Solid Dish Soap In Tin? 97 Most Correct Answers

In some homes, the water from the washing machine drains into a septic tank, which treats the wastewater. A septic detergent will not affect the operation of this system. In other words, it contains no ingredients that can affect the system’s ability to break down waste.

Of course you want to get your clothes as clean as possible, but for your health and the environment you might want hypoallergenic, natural, plant-based options. The best septic tank cleaning product meets these requirements while properly treating domestic wastewater.

What to consider when choosing the best detergent for sewage treatment plants

If a home’s sewage does not drain into a municipal sewage system, it is treated in a septic tank, which, even if in good condition, requires monitoring and regular maintenance. For example, a septic tank should be pumped every 2-3 years.

To maintain optimal function, users should avoid introducing harmful substances into their wastewater treatment plants, including chemicals that affect the beneficial bacteria that break down waste and substances that can create excessive sludge. Consider the following factors when choosing the best sewage treatment plant cleaners.

Powder vs Liquid

When it comes to septic tanks, there is an ongoing debate about powdered or liquid detergents. However, the difference between powder and liquid is not as important as the ingredients in the detergent.

Powder detergents can contain fillers, such as clay or plastic powder, which can build up in the septic tank and cause clogs. Biodegradable detergent powders do not cause this accumulation.

Liquid detergents should also be biodegradable. It’s especially important to avoid chlorine bleach and other harsh chemicals that can kill the beneficial bacteria in the septic tank that break down the waste.

Septic safe

A “septic-safe” detergent contains no ingredients that interfere with the operation of the facility’s waste treatment system.

To maintain an optimal balance of bacteria and enzymes that break down waste, choose septic cleaning products. Avoid detergents with these ingredients:

Artificial whitening and brightening agents

Chemical dyes and fragrances

Chemical preservatives

Chemical surfactants, sulfates and enzymes

chlorine bleach

1,4-dioxane

parabens

phosphates

phthalates

Synthetic foaming and thickening agents

Safer alternatives are low-foaming, biodegradable laundry detergents that contain plant-based detergents. Scents from essential oils pose no danger to the septic tank. Green or eco-friendly cleaning products are among the best soaps for sewage treatment plants.

surfactants

A “surfactant”, a term derived from the expression “surface active agent”, consists of amphiphilic molecules that are adsorbed at the air-water interface. This absorption results in a reduction in surface tension, which facilitates the detergent’s ability to spread and penetrate the fabrics of the laundry.

The reduction in surface tension brings about the desired cleaning effect, since dirt is transported away. Because of surfactants, detergents appear to loosen dirt and stains from clothing and household linen.

Chemical and petroleum based surfactants can damage a septic system by creating sludge. Plant-based surfactants are both septic-safe and effective cleaning agents. The best plant-based surfactants come from palm oil, coconut oil, and soap nuts (soapberries).

Environmentally friendly and biodegradable

Manufacturers of eco-friendly detergents take care not to harm the environment in the manufacture, packaging and use of their products. This makes natural plant-based cleaning products recyclable and comes in biodegradable packaging. In addition, they try to use less energy during their production processes.

Certain harmful chemicals are particularly lacking in eco-friendly, biodegradable laundry detergents, such as B. phosphates; phthalates; 1,4-dioxane; chemical fragrances; synthetic brighteners; and more. Instead, effective biodegradable cleaning ingredients are often derived from plants. Plant-based detergents in biodegradable laundry detergents offer hypoallergenic properties that benefit those with sensitive skin.

Concentrated formulas

A concentrated liquid detergent contains less water in its formula than non-concentrated liquid detergents. As a result, less concentrated liquid is needed to achieve optimal cleaning results.

Concentrated formulas can be economical because a little goes a long way. Users should get more wash loads from a concentrated liquid detergent bottle than from a non-concentrated liquid bottle of the same size.

Since it is difficult to estimate the right amount of concentrated detergent, users may overuse. Excess detergent leaves residue on clothes as well as deposits that can be harmful to heavy-duty washing machines. Always follow the manufacturer’s instructions when measuring liquid detergent.

frequently asked Questions

Anyone who directs domestic wastewater into a septic tank must pay attention to the health and function of the system when choosing the detergent. The right product can support the long-term maintenance and smooth operation of the system. Read on to see a few questions and answers on the best laundry soap for septic systems.

Q. Are detergent capsules bad for septic systems?

As long as the ingredients are fully biodegradable, detergent capsules are safe to use without damaging septic systems.

Q. Can I use bleach with a septic tank?

To break down waste, beneficial bacteria need to thrive in a septic system, and overuse of chlorine bleach can kill the bacteria. Avoid products that contain chlorine bleach.

Q. What do I do if I haven’t used septic detergents?

Keep a septic system healthy by cleaning (pumping) it every 2 to 3 years or when sludge fills the tank to a third of its depth. Start using a detergent that is labeled safe for septic systems.

Q. What ingredients should I avoid when looking for septic cleaning supplies?

Avoid chlorine bleach, ammonia and phosphates. Also, avoid excessive use of chemical-based detergents; Instead, look for biodegradable, plant-based products.

Q. How do I keep a septic system healthy?

Carry out regular inspections and maintenance work, e.g. B. Pumping the tank when needed (or every 2 to 3 years). Keep the septic tank lid closed, secured and easily accessible.

BACKGROUND OF THE INVENTION

The present invention relates to a solid soap mainly composed of a hard and elastic gel of cornstarch – soap – water and its relevant manufacturing process.

Conventional bar soaps typically consist of about 85% anhydrous soap (mainly sodium salts of higher fatty acids), 10-13% water and the usual additives.

Soaps formulated according to these formulas suffer from several disadvantages. In fact, a large part of the active ingredient (in this case soap, up to 50% of it) is useless for detergents and therefore causes high production costs.

In addition, this excess of active ingredients is harmful because of the excessive degreasing effect on the skin (so-called alkaline effect). On the other hand, attempts to overcome the disadvantage of high cost by using soap with higher water content have not yielded positive results. In fact, when used, these soaps produced copious amounts of scabbing while at the same time experiencing a loss of strength.

Various types of additives, drying materials and fillers have been tried in an attempt to overcome these disadvantages. One of these materials is starch, which is known as a filler. The addition of starch made in the earlier techniques was done in such a way as to prevent the formation of gels and dextrins because of possible difficulties in the manufacture and finishing of the product.

It has now surprisingly been found that a soap containing a hard and elastic gel is composed of:

starch, 8 to 28% by weight,

water, 10 to 60% by weight,

sodium and potassium salts of higher fatty acids, 24 to 54% by weight,

can overcome the above disadvantages.

Gels are rigid or semi-rigid colloids containing large amounts of liquid substance, usually water, in which the individual particles are linked together in web-like structures. Gels can therefore be viewed as solid matter, more or less plastic. Then can be divided into two classes, elastic and non-elastic. Partial desolvation of the first class causes the formation of an elastic solid, while in the second class partial desolvation causes loss of elasticity and possible pulverization and/or vitrification of the gel.

Soaps are generally alkaline salts (sodium and potassium) of higher fatty acids (lauric, myristic, palmitic, oleic, stearic, and others). They are formed by the reaction (saponification) of the esters of fatty acids with glycerine and alkalis. These soaps can be classified as: Soft soaps derived from reaction with potassium alkali Hard soaps derived from reaction with sodium alkali.

Starch is a carbohydrate composed of molecules with linear or branched chains connected mainly in micelles by hydrogen bonds or molecular water bridges.

By adding heat to a suspension of water and starch, the network structure of the starch is weakened due to the disruption of hydrogen bonds. Heat causes hydrolysis of the micelles and thus irreversible gelatinization together with swelling of the micelles due to the addition of water molecules to the released hydroxyl groups. It is also known that when this reaction is carried out together with fatty acids or soaps containing fatty acids, the latter form complexes with the linear portion of the starch, creating cross-bonds between macromolecules, bonds that remarkably strengthen the gel structure.

SUMMARY OF THE INVENTION

The subject of the present invention is therefore a soap bar comprising a hard and elastic gel consisting of:

starch, 8 to 28% by weight,

Sodium and/or potassium salts of higher fatty acids, 24 to 54% by weight,

water, 10 to 50% by weight.

The very large variability in the percentages of the three components depends on the ability of the starch to hold water in small or large quantities and due to the fact that the starch-water gel can be modified by adding sodium or potassium soaps within the above can be limited, resulting in a hard and elastic gel.

It is evident that the properties of the final gel (hardness, elasticity, detergency, skin action, foaming power, etc.) vary, albeit not linearly, with the relative amounts of the above three components and with the Na+soap/K+soap ratio .

It has also been found that boric acid or sodium borate has a beneficial effect on the strength of the gel.

A subject of the present invention is therefore also the use of boric acid or sodium borate in the bar soap described above, in amounts which can vary from 0.05 to 5% by weight of the total weight of the composition. The soap described in the present invention may also contain the additives and auxiliary materials normally used in soap compositions.

Finally, another subject of the present invention is a process for preparing the soap bar described above, comprising the following operations:

(a) mixing starch, water, sodium and potassium salts of the higher fatty acids to obtain a liquid suspension;

(b) heating and mixing the mixture (a) at a temperature between 60 and 100°C to obtain, after gelatinization of the starch, a semi-liquid paste with a water content between 48 and 52% by weight;

(c) further heating the paste (b) to a temperature ranging from 90°C to 160°C to obtain, after a second gelatinization stage, a denser paste with a gel structure having a higher strength than the paste of phase (b ), the water content now being between 45 and 49% by weight.

The disadvantages of conventional bar soaps, as described above, are overcome by the bar soaps which are the subject of this invention. These new soaps are capable of a very efficient washing performance and, due to their high starch content, do not show any harmful effects on the skin due to the alkaline effect. On the contrary, they have a beneficial dermatological effect precisely because of the well-known beneficial effect of starch on the skin.

In addition, because of the lower soap content and because of their very high water content, the soaps according to the invention are much cheaper than those known from the current state of the art. In addition, these soaps do not tend to form plaque during their use, due to their particular gel structure that retains the water they contain.

Whilst the soaps of the present invention are particularly suitable for use as toilet soaps because of the above properties, they can also advantageously be used as laundry soaps.

It is evident that proper proportions of the components are very important to optimize the following variables:

Obtaining a hard and elastic gel with minimal heat input;

low consumption of the product used;

resistance to water;

dermatological properties of the product, taking into account the beneficial effect of starch and the adverse effect of soap;

Ability to bind large amounts of water to the gel;

foam properties, appearance, pleasant touch;

Ability to incorporate multiple additives such as fragrances and colorants without weakening the gel structure.

The proportion of the components can therefore be easily determined by a person skilled in the art through preliminary tests in order to adapt the composition to the changing requirements of the market.

Corn starch is preferably used as the starch, without this preference restricting the possible use of other types of starch.

The soap preferably used is coconut oil soap, which can be replaced by any other type of soap, for example, palm kernel oil soap. Below are the average compositions (in % by weight) of coconut oil and palm kernel oil:

______________________________________ Coconut oil Palm kernel oil ______________________________________ Saturated acids: caproic acid C 6 H 12 O 2 traces traces caprylic acid C 8 H 16 O 2 8.0 2.7 capric acid C 10 H 20 O 2 7.0 7.0 lauric acid C 12 H 24 O 2 48 ,0 46.9 Myristic acid C14 H28 O. sub.2 17.5 14.1 Palmitic acid C16 H32 O2 8.8 8.8 Stearic acid C18 H36 O2 2.0 1.3 Unsaturated acids: Oleic acid C18 H34 O 2 6.0 18.5 linoleic acid C 18 H 32 O 2 2.5 0.7 ______________________________________

A mixture of sodium and potassium soap with the proportions is preferred

100 to 0 Na+ /K+ to 30 to 70 Na+ /K+

The higher the amount of K+ soap, the lower the strength of the product, the more difficult it is to handle and process, the higher the amount of foam and its rapidity of formation.

In addition to additives, auxiliaries can also be used to improve product properties or better adapt them to market requirements.

For example, sodium carboxymethyl cellulose, polyvinyl alcohols with any degree of substitution (PVA), resin, formalin or proteins can be added. Other materials, types and amounts of use in the formula are well known to soap experts. These materials can be used in the proportions:

______________________________________ Sodium carboxymethyl cellulose 0.1 to 10% by weight Polyvinyl alcohol 0.1 to 5% by weight Resin (rosin) 0.1 to 5% by weight Protein (e.g. gelatin) 0.1 to 5% by weight % Formalin 0.0 to 0.1% by weight” ______________________________________

EXAMPLE 1

Here follows a typical starting composition to be processed according to the method, also an object of the present invention.

Composition 1: % by weight Na⁺ soap from coconut oil, 36% solids 63.66 content in water K⁺ soap from coconut oil, 38% solids 9.84 content in water boric acid, 5% solution in water 1.74 sodium chloride , 100% solids (from 1.04 wet soaps above) Sodium Chloride, 20% solution in water 3.47 Industrial water 4.17 Stearic acid 0.35 Cornstarch, 90% solids in water 15.63 Formalin, 30% solution in water 0.10 100.00 ______________________________________

The composition of the soap at the end of the entire manufacturing process is as follows:

______________________________________ Composition 2: wt% ______________________________________ Coconut Oil Sodium Soap 28.84 Coconut Oil Potassium Soap 4.70 Sodium Borate, 100% 0.10 Sodium Chloride, 100% 2.18 Stearic Acid, 100% 0.44 Corn Starch, 100% Solids 17.70 Formalin, 100% 0.04 water 46.00 100.00 ______________________________________

The formalin used is a preservative which can be substituted with others known and normally used in the manufacture of conventional soaps.

Composition 2 can be dried to obtain a soap containing up to 10% moisture, increasing all other components proportionately. This drier product differs from Composition 2 because of its greater hardness, slower consumption rate, easier finishing and packaging, higher softening point.

EXAMPLE 2

production method

To explain the production process, composition 1 is taken as an example and processed into composition 2.

The manufacturing process begins in a stirred kettle, where the following materials are added in order:

Water;

Wet soap obtained through the normal soap making process;

boric acid solution.

The mixture is heated to a temperature in the range from 60 to 95°C and the pH is adjusted to a value of 9 with hydrochloric acid and/or citric acid. Sodium citrate, melted or powdered stearin, starch and formalin solution are added in order. The first stage of gelatinization is almost immediate; The liquid suspension turns into a non-dense paste in a few minutes. This step, carried out for about 10 minutes with constant stirring, results in a paste that will become denser over time. After a maximum of 30 minutes, the paste no longer increases in strength.

At this point in the manufacturing process, the water content is around 50%. The paste is heated to 100-150°C by, for example, milling in a heated roll mill for a time between 10 and 30 minutes. It is the heating that is important, not the physical action of grinding the soap. Here a second gelatinization phase takes place, resulting in a paste much denser and firmer than that obtained after the first heat treatment.

The paste is now smooth and manageable. The water content is about 47%.

EXAMPLE 3

addition of perfume

The paste obtained in the previous example is transferred to a mixer with a double blade stirrer (approx. 40 rpm) and cooled to 40 to 60.degree. At this temperature the perfume is added. Immediately after adding the perfume, the paste significantly loses strength and becomes very soft and sticky. Constant stirring of the mass is continued and after about 5 minutes the paste returns to its former state of non-tacky consistency. The paste is now in a condition to be extruded, pressed and packaged like regular soap. Its water content is around 46% and it is ready for packaging.

The softening point of the product is between 45 and 50 °C at 46% humidity. However, this negative quality can be improved by reducing the water content of the product, which can be done in a regular soap dryer before adding perfume. In order to increase the softening point, the level of sodium chloride and/or sodium citrate can be increased while keeping it within the necessary limits to prevent “whitewashing” of the finished soap, ie migration of mineral salts from within the soap the surface.

EXAMPLE 4

Aging and packaging of the product

The third phase of gelatinization takes place during the aging of the product: the hardness and elasticity of the product increase following an asymptotic curve that reaches the almost flat part after 48 hours of aging. At this stage the gel has reached its final structure. The soap cake is now a firm mass with a smooth surface, pleasant to the touch, elastic. It softens when heated above 50°C, but returns to its previous state when aged at lower temperatures.

The manufacturing process, machinery and equipment described above can be modified by an expert in these techniques to improve the efficiency of the process. However, in order to obtain the product described above, it is essential that, after the first gelatinization phase, the liquid mixture and the paste are heated homogeneously in order to complete the gelatinization of the starch. Mechanical processing of the paste is necessary for even heat distribution but has little or no effect on the gel structure. On the contrary, excessive mechanical processing of the paste in the rolling mills can damage the structure of the starch-water gel due to the “shear” effect.

The product should be packed in a waterproof film to avoid high moisture loss. The packaged soap should be stored in a hard case to allow storage in places and warehouses where the room temperature may be high.

The quality of the product thus obtained is remarkably superior to that of a conventional toilet soap. This superior quality derives both from the particular physico-chemical structure of the product and from the intrinsic properties of the materials used. In fact, consumer tests have clearly proven that this product is superior to traditional soaps in terms of skin impact, amount and type of lather, rinsing, wet and dry feel. Its superiority is also demonstrated by its ability not to create any deposits in the soap dish despite the very high water content. It has also been found that some of the consumers who are allergic to conventional soaps have used this product with no ill effects. After all, the production costs are significantly lower than for normal soaps.

EEK! i feel your pain

Why does it come to a soap soap?

Something speeds up the saponification process. It is usually a fragrance oil or essential oil.

For fragrance oils, look for flowers and spices, and for essential oils, look for spices (cloves, bay leaves, cinnamon, etc.). Some fragrances are labeled “may cause acceleration”. These are scents that, combined with some factors, tend to get stuck.

Temperatures – Temperatures play a large role in the movement of your soap to and through saponification. Cooler temperatures will cause your soap to move more slowly; Higher temperatures will cause your soap to move faster. Higher temperatures in combination with a fragrance oil or essential oil known to work quickly = soapy water! Soap cooler (75-85 degrees F) when working with fast moving fragrances and essential oils.

Watch out for other additives that can cause your soap to heat up like oatmeal, honey, beer, etc.

Water Amount – Reduced water combined with a difficult EO or FO can cause your soap to set. If you’re using a water discount when lathering, make sure you’re not using a tricky EO or FO.

Blending – Using an immersion blender can help speed up tricky EOs and FOs. Stir by hand or mix with a whisk.

Add your fragrance or essence to your melted oils BEFORE adding the lye solution. Sometimes diluting the FO or EO helps slow it down.

What can you do?

You can prevent this by paying attention to the temperature and the amount of water. Soap up cool and don’t go without your water. If you’re using a new fragrance or essential oil and don’t know how it will affect your soap, do a 1 pound test batch first. If it happens, don’t panic!

If there is a slight sticking where exactly where you got stuck with the hand blender at the bottom of the pot, break off with the hand blender and stir to trace by hand.

If it’s a serious seizure and you can’t save it, you have three options!

Hot Process it – Put it in a crockpot and process it hot. If it’s past the point where it can be stirred smoothly and poured into a mold, you can work it hot. Just put it in a saucepan and cook until the entire mass has gelled (become translucent), and then put it in a mold.

Repeat – If you managed to get it into a shape but it’s UGLY, you can stack it again. Here are rebatch instructions. If you do it the day after, you usually don’t need to add extra water. If you’re making it again weeks later, feel free to add some water to the cutlets before cooking.

Chunk it – You can let your soap sit until it’s set. Cut it into small pieces. Make a new batch of soap and add the bars to the new batch. That’s how I came up with some really nice designs. Here’s a soap that Benjamin and I had to chop up to fix. I love the way it looks!

If you’re in the soap making business, chances are you’ve had a soap spree. If you are new to soap making, one day it will happen! Keep calm and know there is a way to fix it! It may not turn out the way you imagined, but you will end up with a unique soap with a unique story.

Happy soaping again!

You can melt a bar of soap or leftovers in a variety of ways to form new soap. To melt soap on the stovetop, first shred it with a cheese grater. Then heat it in a saucepan with 8 cups of water over low or medium heat. When the soap is completely melted, turn off the heat, cover the pot, and let sit for 12 to 24 hours. You can also melt soap in the microwave. Simply cut into small cubes in a glass bowl. Then, microwave the soap for 30 seconds at a time, stirring each time until melted. For more tips, including how to melt soap with a double boiler, read on!

THANKS to the internet, cleaning fans have a long list of quick and easy tricks they’re dying to try around the house.

If you don’t use cling film to clean your shower hose, make sure your baseboards are dust-free by wiping them down with fabric softener.

6 cleaning fans swear by frozen dish soap to clean burnt-in grease Credit: tanyahomeinspo/Tiktok

The latest trend now is for cleaning fanatics to freeze dish soap in ice cube trays.

They believe this is the secret to tackling dishes covered in baked-on dirt, as the detergent easily penetrates the dirt and removes it effortlessly.

TikTok user @tanyahomeinspo tried the hack herself and revealed how easy the frozen cubes of dish soap clean dirty oven racks.

In a step-by-step video, she was seen filling an ice tray with dish soap before taking out a frozen cube and rubbing it over each grease-covered groove of the rack.

Just like that, the fat started falling off as the frozen cube melted and worked its way into the dirt and grime.

She had a sparkling oven stand that looked as good as new and people were amazed at her results.

Hundreds liked the video shared online, with one person commenting: “Omg. That’s brilliant.”

Another said: “I’ll do that right now (sic).”

A third agreed: “I’m definitely going to try that.”

Meanwhile, a mom revealed how to remove sweat stains from white clothes with just one ingredient.

Plus, here’s why a lemon is the secret to all your kitchen cleaning problems, and it’ll smell amazing too.

And a professional cleaner reveals how often you should clean your toilet brush – but sparks debate about her method.

“I try very hard to give evidence-based information and not be anecdotal. I’m a scientist with decades of experience in this field, working with a group of scientists from the International Forum for Home Hygiene, all of whom share the same commitment. So what can I say? Using soap or detergent is better than not using anything! But I think it depends on what you flush. For example, if you have heavily soiled, greasy pans and dishes, I think the liquid detergent cuts through the grease better and loosens the microbial contaminants so they wash away. And for containers or dishes that have been in contact with raw meat and chicken and are likely to be contaminated with bacteria like salmonella, campylobacter, or E.coli, I would want to use a liquid detergent because of the chances of bacteria surviving bar soap and the soap dish.”

Q: I’ve run out of detergent capsules for my dishwasher. Can I use detergent in a dishwasher?

A: That’s a really good question that a lot of people ask themselves when they run out of the handy dishwasher capsules we use so often. Years ago it was common to use a liquid dishwasher soap solution in a dishwasher, although these days most people are turning to capsules. It might make sense that a liquid dish soap could play the same role, but it’s not as cut and dry.

Learn why these two soapy solutions aren’t perfectly interchangeable, what happens when you try to use dish soap in a dishwasher, and some homemade cleaning options.

Dishwashing detergent is designed to clean without foam.

Although dish soap is a soap, it doesn’t work like other types of soap. Dishwashing liquid is designed to clean with a thick suds foam. Instead of suds, dishwashing detergent relies on enzymes to clean up the mess.

When you put dish soap or a capsule in the funnel of your dishwasher, it will dissolve in the water. As the water sloshes and splashes around in the dishwasher, the enzymes in the detergent attach themselves to stains, dirt and residue. They break down the long protein and starch chains into smaller and smaller particles until they can be washed away with the water.

What happens when you use regular liquid dishwashing detergent in a dishwasher?

Unlike dish soap, dish soap is designed to create a thick, sudsy foam that helps break down food and stains on pots, plates, cups, and bowls. It works very differently than dishwashing detergent. Although both come in liquid form, they’re not apples for apples.

If you use the same amount of detergent as dishwashing liquid in a dishwasher, you should be prepared for a mess. The detergent creates a thick foam of soapy water and bubbles in the dishwasher, which eventually leaks through the door and drains into the sink. That might be funny in movies, but it’s not so funny when it’s your flooring and drywall that could get damaged.

If you put regular washing-up liquid in a dishwasher, stop the cycle immediately and rinse the appliance thoroughly.

Things happen and we can sometimes get so busy with daily life that we make the mistake of putting dish soap in the dishwasher. The first step is to stay calm and the second step is to flush the soap out of the system.

If you accidentally put detergent in a dishwasher, stop the washing machine immediately. When things have calmed down a bit, put the washing machine in rinse mode to get rid of the suds as quickly as possible. This could still result in overflowing sinks and suds on the floor, so you might have to stop and restart the rinse cycle a few times in the name of damage control.

Once the suds are gone, you should run the dishwasher at least one more time to remove the soap residue inside. You might also want to clean the dishwasher afterwards.

Other foam soaps that spell disaster when used in the dishwasher:

Dish soap isn’t the only type of soap you shouldn’t use in a dishwasher. Any soap that forms a thick, sudsy lather will achieve the same results. Other foam soaps that you shouldn’t use in a dishwasher include:

hand soap

shampoo

car wash

shower gel

Solution for high-pressure cleaners

Realistically, you wouldn’t want to put these in the dishwasher anyway, as these soaps aren’t food safe. But understand that any type of foam soap makes a big, sudsy mess and can even damage your dishwasher. If you must use household soap other than dish soap, a much better option is to fill your dishwasher’s soap container 3/4 full with baking soda and add just a few drops of dish soap.

How to make homemade dishwashing liquid in no time.

While you really should only use dish soap (otherwise you could damage your machine and void your warranty), there are some homemade solutions that will result in clean dishes in your dishwasher.

This recipe is a dry mix, so it’s best kept in a large jar or bag for easy scooping and pouring. All you need is:

1 cup washing soda

1 cup baking soda

1 cup kosher salt

Just mix these ingredients together. Pour the mixture into the detergent dispenser to use. If you prefer a bit of fragrance, you can use a drop or two of essential oils like lemon or orange, or any other scent that smells nice and clean. Add to the soap container before running the washer, not to the dry mix in the jar.

*NEW PACKAGING

Zero-Waste Vegan Dishwashing Block™ Bar is a cleaning powerhouse with a rich, frothy lather. Removes stubborn dirt and grease without drying out hands.

You can even use it for cleaning tasks around the house. Remove stains from laundry, remove labels from glasses, spot clean your carpet, use it to wipe down counters… it’s a truly versatile product.

Each 5.9 oz bar lasts a LONG time. Based on customer feedback, it is estimated that a single person washing all dishes by hand (no dishwasher) will last around 5 months. If the person only uses the rod for pots and pans, it will last even longer.

Each block can replace up to 3 bottles of typical liquid dish soap. (based on real customer feedback)

Use: Scrape dishes to remove excess grease and food. Dampen the sponge for plates, bowls and cups and rub the soap block to create foam. (Repeat as needed to refresh lather.) Wash item and rinse well. Works in warm or cold water. We prefer warm water for best results. Use a scrubber or scourer for pots and pans.

For particularly shiny crockery: Wipe the dishes dry with a cloth.

Pro kitchen tip: Use the same Dishwashing Block™ soapy water to clean your sink when it gets dirty. This is safe to use on porcelain, stainless steel, stone and glass sinks. We’ve seen customers use it to clean dirty and stained oven surfaces too!

Please note: using the block exclusively with a strong scouring pad or scrubber will wear it down faster than using a soft sponge or cloth.

When people make DIY soaps, it turns out that they are often too soft. We have the solution! Use these 5 tips to make your bar soap tough and durable.

Make your DIY soap tougher

As a soap maker, I often hear the question, “How do you get your DIY soap bar so hard?” or “How can I make my soap last longer?”

The hardness of the soap depends on the formula used and the time it takes to harden. But there are a few things you can do to make your DIY soap tougher, which in turn will help it last longer.

How to get tougher, longer lasting homemade soap

If you’ve never made homemade soap bars before, you might want to check out my basic recipe and see how weight and volume measurements work when making cold process soap. You can also check out this article on lye if you’re a little hesitant about using it. After you’ve made a few batches, it’s time to start thinking about how to improve the process and get a harder, longer-lasting bar.

Here are five things that can lead to a harder bar:

1. Use a water reducer

You have to dissolve lye in water to turn oils into soap. The amount of water you use will affect the curing time and will also affect the outcome of the DIY bar’s hardness.

Too much water will cause the bars to become soft and take longer to set. They also lose a lot of weight during curing, potentially leaving you with a softer bar. If the recipe calls for 5.75 ounces of water, you can decrease it by about 10% or use about 5.25 ounces. This allows your bar to cure much harder.

2. Add some wax

A small amount of beeswax added to the melted oils will help harden your DIY soap bar. If you’re looking for a vegan alternative, you can also try soy wax, bay wax, or any other type of vegetable wax. You can also try kokum butter, which is one of the hardest butters known to man.

If using my basic recipe, about 3 ounces melted and added to the oils will do just fine. Don’t wait to add these to Trace; They just harden and don’t clump or disperse in the soap base at all.

3. Add sodium lactate

Sodium lactate is a clear liquid that comes from the natural fermentation of sugars found in things like sugar cane and sugar beets. Used at about a 1% level, or about four tablespoons (2.25 ounces) for this recipe, sodium lactate will significantly harden your DIY bar. This is especially recommended for custom molds with intricate designs, as they can sometimes be very difficult to demould.

4. Increase the olive oil

Oils in soaps have different properties. And some oils cannot be substituted for others because of a certain SAP value. Simply put, the SAP value is the amount of caustic it takes to turn that oil into soap. There’s a lot more to the numbering system, but all you really need to know is that the numbers have to be close together to swap them out.

Coconut oil has a very different SAP value than olive oil and should be left alone in the recommended amount. But olive oil comes very close to certain other oils in terms of SAP. So you could decrease the amount of “other oil” recommended in this recipe and increase the amount of olive oil. The DIY soap bar will still look the same, but the end result will be a tougher bar.

5. Add some salt

Like sodium lactate, salt helps harden soap into very hard bars. Add about ½ teaspoon per pound of oil to the recipe. This recipe has 14.25 ounces of oil, so between ¼ and ½ teaspoon of salt will do. Stir it well into the lye solution and make sure it is completely dissolved before adding the lye to the oils.

Be sure to use pure salt with no additives; Any additives may affect the outcome of the final bars.

Have you used any of these methods to make homemade soap bars harder? If yes, how did it work?

With so many zero-waste dishwashing detergents to choose from, how do you decide which one is best for you? This article looks at the plastic-free options, including solid bars, powdered soap, dishwasher tabs, liquids, and DIY options.

Who would have thought that washing dishes could be so much?

Types of zero waste dish soap

Solid bar soaps

The most popular and widely used are traditional bar soaps.

These bars are usually unscented (some contain essential oils or natural fragrances) and will last for a few months with regular use.

No Tox sells a 22.5 ounce bar of soap that could last for years (plus smaller sizes).

To use, rub your sponge or brush over the soap until you’ve created enough suds, then use that to wash your dishes.

Soap bars should be kept dry between uses so they last as long as possible.

Consider getting a zero-waste soap dish to ensure proper drainage (or make one yourself with a bowl and some rocks).

liquids

Liquids are arguably the most natural transition to a zero-waste dishwashing routine, but they’re also the most difficult zero-waste alternatives to find because they have to be packaged in a bottle.

If you want liquid soap, it’s best to buy it in bulk from a local store. This way you can reuse containers you already have.

If you don’t have a Zero Waste store near you, you can try Frillaree’s online refill subscription. Another option is to order large quantities from Amazon.

Dishwashing tabs / washing-up liquid

People often think of dishwashers as ecological no-nos.

However, several studies have now shown that newer dishwashers can be more economical than washing up by hand.

Just make sure you:

Use eco mode

have a full charge

Use a zero-waste dishwasher soap

Zero-waste dishwashing detergent options usually come in a box.

These ECO Store dishwashing tabs have been independently tested to ensure effective cleaning.

DIY dish soap

It is always a sense of achievement to create your own organic products.

We’ve had great success with our eco-friendly DIY toothpastes and sustainable mouthwash makeshift recipe, so we figured why not try dish soap too.

Making most homemade dish soap doesn’t require a chemistry degree either, often only 3 or 4 ingredients are needed.

More on that and some tried-and-tested recipes later in the article.

If you’re using a natural soap, you’ll get better results by applying the soap directly to your dishes rather than filling a sink with soapy water. Rinse your dishes, scrub clean with soap and rinse again.

The manufacturers of these dish soaps strive to be sustainable and produce natural products.

Castile soap in bulk

Castile soap is what most zero-waste dish soap options are based on, but you can also just buy pure castile soap.

Traditionally olive oil based, the soap is biodegradable and non-toxic, making it the perfect natural ingredient.

Properly diluted, the soap is even suitable for use on the body.

Nowadays you can find different variations made from a variety of different vegetable oils like coconut or hemp oil.

You can find it in both solid soap form and liquid form.

For the liquid form, to keep the packaging small, we recommend buying a concentrated version in bulk, which you can then dilute with water as needed.

For dishwashing we recommend a dilution ratio of 1 part castile soap to 10 parts water.

Castile soap has an alkaline pH, so it will react with anything acidic, like vinegar and lemon. This reaction nullifies the cleaning properties of the soap and leaves a white film on your dishes.

Very hard water can produce the same effect. If you notice this, installing a water softener should fix the problem. top tip

Castile soap is so great because you can use it for so much more than just washing your dishes, it has almost unlimited uses around the house.

Its purifying properties make it useful for everything from cleaning your toilet to a bug spray for plants.

If you want to use your soap for other things, check out this super handy dilution cheat sheet.

Another advantage of castile soap is the price, especially if you buy it in bulk. If you are looking for a cheap, zero-waste dish soap, then Castile Soap is the way to go.

If you can’t find bulk castile soap in your local stores, sustainable options online include:

Recipe for homemade dish soap

Homemade zero waste dish soap is easy to make and takes less than 5 minutes.

Our recipe uses natural ingredients that clean effectively while being good for the environment.

No harsh chemicals are used, so the dish soap is gentle on your skin too.

ingredients

1/3 cup liquid castile soap (add more if you find the soap too weak)

1 – 2 tablespoons baking soda (for really stubborn stains, scrub with a little baking soda first)

1 1/2 cups hot water

A few drops of essential oil of your choice (optional)

If you don’t have liquid castile soap, you can substitute solid soap.

Any bar soap you have at home should work, but we recommend using one of the options above or looking for a traditional olive oil bar.

You’ll need to grate the soap (or blend it in a blender), so you’ll need to use some elbow grease.

method

mix hot water and castile soap / melt grated soap in hot water allow to cool and mix in baking soda while the mixture is still warm (add all the essential oils here) keep in any container shake well before use (if you used a soap block with additives, you may need to shake quite vigorously as the soap can harden)

Homemade dishwashing liquid recipe

If you have a dishwasher, you can also make your own zero-waste dish soap.

Our homemade detergent is much cheaper than exorbitant prices in the supermarket.

Not to mention better for you and the environment.

The amounts given here are for guidance only. You’ll need to experiment with the recipe as the exact amounts you need will depend on the type of water in your area and how dirty your dishes get.

In general, the harder your water, the stronger you should make your detergent.

Adding more citric acid and using white vinegar as a rinse aid will help remove any cloudy residue. You can also try using hotter water or less detergent.

ingredients

1 cup washing soda (for cleaning)

1 cup baking soda (helps cut fat)

1 cup citric acid or lemonade Kool-Aid (antibacterial)

3/4 cup salt (helps soften hard water and adds scrubbing power)

method

Mix all ingredients. Store in an airtight container in a cool, dry place. Use 1 tbsp per charge. As a rinse aid, fill the compartment with white vinegar

If you find the mixture hardens after storage try adding some rice to the mixture, old rice filled pantyhose will work and is reusable.

This will suck moisture out of the mixture and prevent clumping.

To make dishwashing tabs, scoop the mixture into a silicone ice tray and allow to set.

Final Thoughts

There are MANY zero-waste dish soap options out there. It may take a few tries to find the perfect one for you, but once you have it you won’t look back.

Now you wash your dishes with Zero Waste dish soap, why not try de-linting your clothes with a Zero Waste Lint Brush?

Q: I’ve run out of detergent capsules for my dishwasher. Can I use detergent in a dishwasher?

A: That’s a really good question that a lot of people ask themselves when they run out of the handy dishwasher capsules we use so often. Years ago it was common to use a liquid dishwasher soap solution in a dishwasher, although these days most people are turning to capsules. It might make sense that a liquid dish soap could play the same role, but it’s not as cut and dry.

Learn why these two soapy solutions aren’t perfectly interchangeable, what happens when you try to use dish soap in a dishwasher, and some homemade cleaning options.

Dishwashing detergent is designed to clean without foam.

Although dish soap is a soap, it doesn’t work like other types of soap. Dishwashing liquid is designed to clean with a thick suds foam. Instead of suds, dishwashing detergent relies on enzymes to clean up the mess.

When you put dish soap or a capsule in the funnel of your dishwasher, it will dissolve in the water. As the water sloshes and splashes around in the dishwasher, the enzymes in the detergent attach themselves to stains, dirt and residue. They break down the long protein and starch chains into smaller and smaller particles until they can be washed away with the water.

What happens when you use regular liquid dishwashing detergent in a dishwasher?

Unlike dish soap, dish soap is designed to create a thick, sudsy foam that helps break down food and stains on pots, plates, cups, and bowls. It works very differently than dishwashing detergent. Although both come in liquid form, they’re not apples for apples.

If you use the same amount of detergent as dishwashing liquid in a dishwasher, you should be prepared for a mess. The detergent creates a thick foam of soapy water and bubbles in the dishwasher, which eventually leaks through the door and drains into the sink. That might be funny in movies, but it’s not so funny when it’s your flooring and drywall that could get damaged.

If you put regular washing-up liquid in a dishwasher, stop the cycle immediately and rinse the appliance thoroughly.

Things happen and we can sometimes get so busy with daily life that we make the mistake of putting dish soap in the dishwasher. The first step is to stay calm and the second step is to flush the soap out of the system.

If you accidentally put detergent in a dishwasher, stop the washing machine immediately. When things have calmed down a bit, put the washing machine in rinse mode to get rid of the suds as quickly as possible. This could still result in overflowing sinks and suds on the floor, so you might have to stop and restart the rinse cycle a few times in the name of damage control.

Once the suds are gone, you should run the dishwasher at least one more time to remove the soap residue inside. You might also want to clean the dishwasher afterwards.

Other foam soaps that spell disaster when used in the dishwasher:

Dish soap isn’t the only type of soap you shouldn’t use in a dishwasher. Any soap that forms a thick, sudsy lather will achieve the same results. Other foam soaps that you shouldn’t use in a dishwasher include:

hand soap

shampoo

car wash

shower gel

Solution for high-pressure cleaners

Realistically, you wouldn’t want to put these in the dishwasher anyway, as these soaps aren’t food safe. But understand that any type of foam soap makes a big, sudsy mess and can even damage your dishwasher. If you must use household soap other than dish soap, a much better option is to fill your dishwasher’s soap container 3/4 full with baking soda and add just a few drops of dish soap.

How to make homemade dishwashing liquid in no time.

While you really should only use dish soap (otherwise you could damage your machine and void your warranty), there are some homemade solutions that will result in clean dishes in your dishwasher.

This recipe is a dry mix, so it’s best kept in a large jar or bag for easy scooping and pouring. All you need is:

1 cup washing soda

1 cup baking soda

1 cup kosher salt

Just mix these ingredients together. Pour the mixture into the detergent dispenser to use. If you prefer a bit of fragrance, you can use a drop or two of essential oils like lemon or orange, or any other scent that smells nice and clean. Add to the soap container before running the washer, not to the dry mix in the jar.

A good dishwashing liquid effectively removes food residue, degreases and leaves a shiny finish. It can be in the form of a gel, liquid, powder or tablet. Which type you choose will primarily come down to personal preference, but consider the quantity in the pack and the scent when shopping. Also remember: there are eco-friendly formulas, rinse aids and hard water solutions. The Finish Powerball Quantum dishwashing tabs are our favorite because they have three chambers of cleaning power that are convenient to use and effective. The tabs also make glassware look very shiny. Here are the best dishwashing liquids on the market to keep your plates, cups, bowls, mugs and more sparkling and feeling fresh.

Soap is a pretty useful thing. Without them we would be a lot dirtier and a lot smellier. If you’ve ever lost sight of your soap in the bath, you know how difficult it can be to find it because it will sink to the bottom and slide around in the water when you try to reach for it. However, there is a special soap called Ivory Soap that floats! They mix air with the soap to keep it from sinking! This air also allows us to do a really neat (and kinda messy) experiment with ivory soap that will teach us a little about the properties of matter. Make sure you have Ivory Soap as this is the only one that works with it!

procedure

Open the bar of soap and place it on your plate. Put the plate in the microwave. Set the microwave to high for about a minute and a half. Stand back and watch what happens!

summary

Make sure you let the soap cool down for a while before removing it from the microwave. Once it’s cool enough, you can feel it. How does it feel? It’s hard? Soft? Bubbly?

The reason ivory soap expands into a big sudsy mess has to do with the air they mix with to make them levitate. Air is a state of matter called a gas. A bar of soap is a state of matter called a solid. The third state of matter is a liquid, like water or juice. Matter takes on different states because the tiny parts that make it up, called atoms and molecules, move at different speeds. In gases like air, they whiz around quickly and go anywhere. In liquids they slide past each other. In solids, they’re really bonded together and just vibrate in place.

When you add heat to any matter, that new energy moves the atoms and molecules faster. Molecules in a solid vibrate more strongly. In a liquid, they move farther and faster. If you add enough energy to a solid, these tight bonds break and the molecules begin to flow past each other as a liquid. If you add enough energy to a liquid, the molecules start doing their own things and start flying in all directions and you end up with a gas. Think of water going from ice (solid) to regular water (liquid) to vapor (gas) as it gets hotter.

Because the molecules move more and further when you add heat, whatever you heat actually expands and gets bigger the hotter it gets! Since gas molecules are already running all over the place, new energy will make a gas expand much more than a solid. So when you heated the ivory soap, both the solid soap and the air bubbles inside it started to expand, but the air bubbles expanded much more than the soap, causing it to foam up into a giant soap monster!

All cleaning products – whether for hands, hair, clothes or dishes – work on the same principle: dissolve and wash away oils and dirt. However, different products are formulated for specific conditions and are not interchangeable.

The main differences are in pH, the presence or absence of bleach, and the types of surfactants — long molecules that are water-loving on one end and oil-loving on the other. “Surfactants are active ingredients that we put in cleaning products that bridge the gap between water and greasy dirt and help wash it away,” says Allen Clauss, a chemistry professor at UW-Madison who previously worked at consumer goods company Procter & Gamble .

Automatic dishwashing detergents use a brute-force approach that’s effective but far too harsh on skin, breaking down stains and high-pH foods and chlorine bleach. “It’s a great way to clean your dishes, but it’s not something you want to get your hands on,” says Clauss. Hand dishwashing detergents contain no bleach and use surfactant blends that are kind to the skin and have a near-neutral pH.

Detergents fall somewhere in between – tougher than hand dishwashing products but gentle enough on fabrics and dyes. Traditional powder versions are closer to automatic dishwashing detergents and use a higher pH to clean, while the newer liquid detergents are closer to neutral pH and rely more on surfactants that are less susceptible to water hardness, enzymes to break down proteins, starches and fats and water soluble polymers to help disperse dirt and oils.
