MMA VS EMA for acrylic nails. How do you tell the difference? from IntiMD support

You may have received or made your own acrylic nails for a while and now you’re hearing rumors about EMA and MMA and not sure what to believe. We are here to tell you the difference between the two and what to look for in acrylic nails.

What is MMA and why is it illegal?

MMA (methyl methacrylate) is a common ingredient in professional nail products used in the early days of the nail industry. This acrylic product is now illegal when used on the nails as it can cause permanent loss and damage to the natural nail as well as numbness in the fingers. MMA is also a powerful monomer that can cause natural nails to break off abruptly, leading to rapid infection.

What is EMA and why is it safe?

Most professional nail makers widely use a product called EMA (ethyl methacrylate) which has been declared safe and approved for use in the beauty industry as it does not damage the nail plate in any way. This means that it is not likely to trigger any allergic reactions.

How can you tell the difference between EMA and MMA acrylic paints?

There is a quick test you can do by buffing the shiny layer off the nail and soaking the whole nail in 100% acetone for 30 seconds.

If you take your nail out of the liquid and examine if it’s still shiny and a little slimy but not crumbled, it’s an MMA acrylic.

If it’s an EMA acrylic, after 30 seconds the acrylic should start to crumble, which is what you want to see.

Another way to distinguish EMA from MMA is that MMA nail enhancements are very harsh and have a yellow tinge, “fishy” odor, and grainy texture. The improvements are usually finished by spray-painting the tip white rather than using white acrylic.

What is a product that contains EMA and no MMA?

IntiMD’s (also on Amazon) Professional Liquid Monomer Glamorshield is not only a great option for applying acrylic nails, but it’s also MMA-free, making it a safe alternative. It also contains a non-yellowing formula, is non-toxic, and is made in the USA.

Glamourshield delivers a strong foundation with a smoother finish that allows the color to be much more vibrant and last longer.

Methyl methacrylate (MMA), a liquid adhesive that some manicurists use to glue artificial nails, was banned by the Food and Drug Administration in the 1970s, but retailers still sell it; Nail professionals still buy it and in the end, women everywhere would pay for it in more ways than one.

This chemical, when combined with a polymer powder, becomes an ingredient that not only has the power to beautify pretty acrylic nails that you’re paying to attach and paint, but also some cute rashes and blood blisters (among other health issues).

After complaints from consumers and pressure from the beauty industry, the FDA has banned the use of MMA from nail care products. Even though MMA is banned, the FDA doesn’t screen cosmetics before they hit shelves, so irresponsible nail salons can still get their hands on it. MMA is now banned in more than 30 states. Some nail salons, like those throughout Pennsylvania, New Jersey, and Delaware.

NBC10 investigator Lu Ann Cahn went into a supply store in South Philadelphia that sells MMA; The results weren’t pretty. The bottles on the shelves were not labeled. So Cahn asked the saleswoman, who admitted the stuff in the bottles was MMA. There is no law in Pennsylvania against the sale of MMA to nail salons and supply stores, although its use is illegal.

Up to 18% of people exposed to MMA will have serious problems, a Philadelphia dermatologist said.

What the heck is MMA?

The good news first: MMA is NOT known to cause cancer.

Now the bad news: MMA can cause skin allergies and rashes, loss of sensation and pain in the fingertips, permanent loss of the nail plate. It can irritate the eyes, nose and throat. The worst thing is that your nails may never grow back.

According to the National Nail Council (NMC), there are four main reasons MMA should NOT be used:

MMA nail products do not adhere well to the nail plate. In order for these products to adhere, nail technicians must grind the surface of the nail plate with a coarse-grit abrasive file, resulting in thinning and weakening.

MMA creates the hardest and most rigid nail enhancements, making them very difficult to break. If pinched or pinched, the overly filed and thinned natural nail plate often ruptures before MMA reinforcement, resulting in severe nail damage and possible subsequent bacterial infection.

MMA is extremely difficult to remove once it adheres to the nail plate. Because it does not dissolve in product removers, it is commonly pryed off the nail plate, causing even more damage to the overly thinned nail plate.

Nail professionals who use these inexpensive gray market products are often untrained in the proper procedures for proper nail plate preparation, controlled product application, proper care, and safe removal. They often engage in unsafe practices, work in unsanitary conditions and do not receive professional training.

MMA Warning Signs:

Manicurists will most likely wear a mask

Use of a drill – even more so if the drill is damaging or painful

Low prices

Strong, strong smell, different from normal nail acrylic

Unlabeled containers

Nails are VERY difficult to file and extremely difficult to remove – when soaked in solvent, nails usually only take about 20-30 minutes to remove. Artificial nails with MMA can last two or more hours.

Check out these links for even more information about MMA:

Read Lu Ann’s Nail File to learn more about the investigation and for “tips” on how to report a nail salon you suspect is using MMA to the proper authorities.

Pay attention to the products used in nail bars!

You go to a nail salon to have nail extensions put on. They look great, the nails are nice and strong, they hold up well and most importantly you can’t believe how cheap they are compared to other places offering the same type of service.

Have you ever heard the saying that when things seem too good to be true, they usually are!

Recently, many clients came to the salon with big problems and nail damage. Many of these clients go to local nail salons for their enhancements, unaware of the risks they are exposing themselves to. Obviously, attaching nail extensions to a natural nail is a very popular and common practice, so why do you think you’re taking a risk when such a simple procedure is performed? Ok here’s why!

They use a very dangerous product to attach the nail extension known as MMA. Why should they do this? The answer is simple: to maximize their “profit” because the product is really cheap to buy.

What is of utmost concern is the health risk to the customers and technicians using MMA and that is why.

What is the product and why is it dangerous?

It’s called MMA (methyl methacrylate). It has its origins in the dental industry for the manufacture of crowns and bridges. It is also used as a bone cement by orthopedic surgeons in joint replacement procedures. This chemical is not designed to come into contact with skin or nails. Have you ever had to wait for a permanent crown to be made in a lab? This is because MMA in its liquid state should only be used in a controlled laboratory environment by properly trained technicians. This is due to the carcinogenic effect on the body, once cured MMA is harmless.

The use of MMA in nail enhancements has generated plenty of controversy in the US in recent years and is quickly becoming a concern in international markets, apart from the fact that it is labeled with the following warning: “Use it and you will become spontaneous.” Combust” warning from the FDA, there are even more serious reasons to avoid MMA use.

MMA does not bond very well to natural nails

It can stick to the nail only by mechanical adhesion, which requires massive damage to the natural nail plate. The top layers of the board need to be removed to give the MMA something to stick to. After a short period of time, the natural nail plates become thin layers of keratin that tear easily and offer no protection from MMA penetration into the nail bed.

MMA is extremely tough

Due to the great hardness of MMA, the only way to file is through excessive drilling. The surface adhesion of the MMA acrylic to the soft tissue is so strong that even slight trauma to the nail can cause the nail to break and separate from the nail bed. This can lead to severe nail breakage, infection, and loss of the nail plate. Ironically, it is the strength of the acrylic that draws some users to the product. Because MMA is extremely tough, removing and maintaining an MMA reinforcement typically requires the use of a drill. The extra drilling effort required to maintain these improvements leads to situations where technicians burn the nail bed, overthin the plate, and even drill through the natural nail plate.

MMA is also resistant to solvents

This means that it is very difficult to remove. It takes a long time to remove MMA by soaking in acetone. To speed up the removal process, the salon can use an electric drill or an extremely coarse file to remove the MMA acrylic. Since it can be difficult to see where the nail has grown, there is a good chance that the nail will be filed into the natural nail, often leaving a damaged, thin nail plate that leads to permanent nail deformities.

Health risks associated with MMA products range from skin allergies to permanent nail plate loss, including:

nail infection

breathing problems and eye, nose and throat irritation

Permanent nail deformities

Severe allergic reactions

What is the safe alternative in the nail industry?

EMA, most mainstream acrylic manufacturers use a product called EMA (or ethyl methacrylate) which is considered much safer for use in the beauty industry, although close relatives of EMA have a slight but distinctly different molecular structure than MMA. This gives EMA the desirable acrylic qualities without the undesirable side effects so often seen with MMA. EMA has around 25 years of research and development for the nail industry and therefore offers the safest and most advanced option over MMA. Unfortunately, with the rise in salon growth and many salons looking to reduce the cost of supplies, MMA has become a popular nail stick product choice. (MMA is 1/6 the price of EMA.)

How do you know if the salon uses MMA?

There are several warning signs to look out for:

Strong or strange smell. MMA has an unusually strong or strange smell; usually fishy; that does not smell like other acrylic liquids. Odor is present during application and when filling the cured product (for fillings or repairs).

Acrylic nails are difficult or almost impossible to remove. When soaked in acetone it can take up to 2 hours to dissolve when normally it should only take around 20-30 minutes. Therefore, drilling is common in the maintenance and removal of MMA.

MMA acrylic nails are extremely hard and very difficult to file, even with coarse files.

Enhancements are cloudy or milky in color when cured.

Additional signs to look out for:

Low prices for complete sets and infills. Because MMA is very cheap to buy, the cost outweighs the safety at these discount salons, although the health risk is more expensive in the long run.

Unmarked products. Technicians/owners/managers are secretive about the brands of products used in the salon

Dust or ventilation masks used (many technicians today use non-MMA dust masks)

At home manicures are, well, the bomb. They are inexpensive and you can create any type of fake nails you want.

But what happens when you prepare to apply your acrylic nail only to find you’re out of acrylic liquid (aka monomer)?

You don’t have to skip your acrylic manicure because you don’t have acrylic liquid.

You can use a few other options instead of monomer to pair with your acrylic powder.

What is acrylic liquid (monomer)?

Before we discuss what other solvents work with acrylic powders, we first need to figure out what monomer actually is.

After all, there is a reason why nail technicians in nail salons apply acrylic with it.

Monomer liquid combines with acrylic powder into a putty-like consistency that shapes the acrylic nails.

Together they act as a “powerhouse” for acrylic nail formation. Without its liquid counterpart, the acrylic powder would be rough and aesthetically unappealing.

What can be used instead of monomer?

Of course, the best option for your acrylic nails is an acrylic monomer.

But you came across this article while looking for how to use acrylic powder without acrylic liquid.

So if you don’t have the right liquid monomer handy, you can try one of these other methods.

However, keep in mind that they may not perform as well as the actual monomer when applied with acrylic powder.

1. Immerse powder activator

Dip powder is one of the best options for creating acrylic paints. That’s because it’s essentially a form of traditional monomer used in combination with acrylic dipping powder.

However, dipping powder tends to be much more expensive than acrylic liquid. Also, some dipping powder bottles aren’t big enough to hold an acrylic brush, making your job all the more difficult.

Instead of going for Dip Powder with your acrylic, why not use Dip Powder Nails instead? They are much less complicated than acrylic paints from start to finish.

2. Rubbing alcohol

If you’re in serious dire straits and only need acrylic nails to cover your natural nails for a day or two or so, you can opt for rubbing alcohol instead.

This doesn’t create the most stunning nail design you’ve ever seen. It can also be a lot lumpier than you’re used to.

However, it can work as a short-term last resort if you want nice nails for a special date night, for example.

3. Nail Glue

If you happen to have some of this lying around, go ahead and use it!

Surprisingly, it contains some of the same chemicals as the “base coat” product for dip nails.

So you should have no problem getting your acrylics to adhere to your natural nail plate.

Just keep in mind that the texture will be relatively fluid and can be difficult to work with.

4. Polyester resin

Polyester resin can be an excellent alternative to liquid monomers.

However, most people don’t have this on hand, so it’s not a very convenient exchange.

The other problem is that this can cause the surface of acrylic manicures to take on a slightly greenish tint after you let them dry completely.

Obviously this can result in an unwanted acrylic paint.

What not to use

Some items will not work with the acrylic dipping powder, although you may see them suggested elsewhere.

1. Acetone Nail Polish Remover

Do not do it! Acetone Nail Polish Remover is designed to do one thing: remove nail polish.

If you try to use acetone in combination with dipping powder, you will be upset with the result.

2. water

Another big no-go is water. Water does not contain the necessary compounds to help the acrylic adhere.

How to use acrylic powder without acrylic liquid

If you decide to try one of these methods, you’ll use essentially the same steps as you would for a typical set of nails.

Prepare and shape natural nails

Regardless of what type of manicure you create, always start with the preparation of the nails.

This includes using nail polish remover to remove existing nail polish and buffing the nail bed.

At this point, you should also use a nail file to shape your nails.

If you want to lengthen your nails (for example, if you have bitten nails that are too short and want them longer), you should apply the fake nail tips at this time.

Apply primer

A primer is _essential_ when applying acrylics without using acrylic liquid.

A primer not only prepares your nails for adhesion, but this necessary top coat smooths out the nail so that acrylic paint can be applied smoothly and easily.

Create acrylic nails

Use your brush to dip into the liquid monomer substitute.

Then dip it in the acrylic powder.

Put a dab of the acrylic powder and monomer liquid mixture on the nail and then shape the nails to your liking.

Finished

Once the nails are completely dry, you can use a nail file to file away any stains or rough areas.

Then you can add a pop of color if needed.

frequently asked Questions

Can I make acrylic liquid at home?

Some people got lucky by mixing water and non-toxic glue (not made specifically for nails) in one bottle.

What ingredients are in acrylic liquid?

The ingredients found in acrylic liquid include ethyl methacrylate, triethylene glycol dimethacrylate, and dimethylamylamine.

You’re about to do acrylic nails and you’ve got everything on the nail table, but you realize you don’t have enough liquid acrylic monomer. Can you use acetone to apply acrylic powder instead of the monomer?

Can you apply acrylic powder with acetone?

no Acetone cannot be used to apply acrylic powder as it is a strong solvent that will dissolve the acrylic powder and turn it into a mixture of acetone and acrylic powder. This mixture is not synonymous with the end product of a chemically exothermic reaction in the combination of acrylic powder and acrylic liquid.

Acrylic nails are the end product of combining acrylic powder and acrylic liquid. After these two acrylic components undergo an exothermic reaction when mixed together, the combined product is in a solid state.

Adding acetone to acrylic powder is like adding sugar to water. No chemical reaction is generated that solidifies the acrylic powder. The acrylic powder is simply suspended in acetone. Therefore, acrylic powder will not solidify in acetone to be filed and shaped into a nail.

What about non-acetone nail polish remover?

Can you use nail polish remover to apply acrylic powder?

Again, the answer is still a no. Non-acetone or regular nail polish removers do not chemically react with acrylic powder to create a solid product. Like acetone, non-acetone nail polish removers dissolve the acrylic powder and do not react to form a combined solid substance.

If you add a lot of powder to acetone or non-acetone nail polish remover, you will end up with a pasty product, making it impossible to make tough acrylic nails in solid form.

Can you use alcohol on acrylic nails?

Alcohol is another solution that does not react with acrylic powder to make a new product in solid form. You can try adding the powder to alcohol to see for yourself, but it will be a paste-like product, not a solid one.

What can you use if you don’t have acrylic liquid?

If you don’t have acrylic liquid, you should wait until you can get some. Attempting to make acrylic nails where you don’t have both ingredients is impossible.

What liquid is used to apply acrylic powder?

Two different types of acrylic liquid can be used with acrylic powder. They are named after their main ingredients MMA and EMA.

MMA: The main component of this type of acrylic liquid is methyl methacrylate. This type of acrylic liquid was widely used in the nail industry until it was banned by the FDA.

EMA: The main component of this type of acrylic liquid is ethyl methacrylate. This liquid is an FDA approved product.

Can you use different brands of acrylic powder and liquid?

All brands of acrylic nails should have similar acrylic ingredients. They should theoretically be interchangeable. However, as a manufacturer tries to market their brand of acrylic nails to a specific group of users, their acrylic nail system is slightly different from the others.

Different brands of acrylic nails are advertised under using conditions and under different temperatures or seasons. In general they are called:

All-season acrylic systems: Acrylic can be used all year round

Acrylic Quick Systems: They allow the user to quickly create acrylic nails.

Odorless Acrylic: The liquid monomer has no strong odor, suitable for areas with limited ventilation.

So if you try to use a brand of acrylic powder with another liquid acrylic monomer, you will get a chemical reaction that creates solid acrylic nails. However, how quickly or slowly the acrylic paints will set, how close the application will be to using just one brand, cannot be predicted.

Where to buy liquid acrylic monomer

Again, you can’t use acrylic powder without a monomer. Trying to do this is impossible, will only give you more headaches and will ruin your acrylic nails.

You can go back to the nail supply store where you bought your acrylic paints, or you can go online and buy it from their websites. Most major nail manufacturers offer their acrylic nail systems for sale on their websites or on Amazon.

If you are serious about acrylic nails, I recommend the Young Nails brand. The company was founded in 1996 and developed a premium acrylic nail system.

You can go wrong with an acrylic nail system with a long history.

You can buy his acrylic nail systems on Amazon.

Try to stick with one brand name. You know how the product works and its properties and you can be sure of its quality and the valuable acrylic nail expertise that you have acquired through numerous acrylic nail applications.

Conclusion:

So there you are. You’d better wait until you have acrylic powder and liquid acrylic monomer to make acrylic nails. Without one or the other, you’re wasting your time doing the impossible.

Happy acrylic nails!

ACRYLIC OVERLAY ON NATURAL NAILS: A COMPLETE GUIDE

Everything you need to know about applying acrylic to your natural nails.

Concealing damaged nails can make problems worse. Covering up brittle, soft or damaged nails can make existing nail problems worse.

Fake nails can lengthen short nails and make your fingers look long and slender. They can also be harsh on your nails.

In order for acrylic nails (a type of artificial nail) to stick, the surface of your natural nails must be filed until they feel rough. As a result, your natural nails become thinner and weaker. Chemicals in the products used to apply fake nails can irritate the skin around your nails and elsewhere.

The list of health risks does not end here. Removing false nails often involves soaking them in acetone or filing them down. If you intend to wear artificial nails for more than a few weeks, you will need to touch up every 2 to 3 weeks to fill in the gaps that appear as your nails grow. Frequent touch-ups can seriously damage your natural nails.

In short, artificial nails can leave your nails thin, brittle and dry.

Still, some people love the look of fake nails. If you’re one of them, these tips from dermatologists can help you reduce the damage:

Choose soak off gel nails instead of acrylic nails. While gel nails can cause nail brittleness, peeling, and cracking, they are more flexible than acrylic nails. This means your own nails are less likely to break.

You should ask for gel nails that peel off rather than ones that need to be filed off.

Go to a salon that uses an LED curing light instead of a UV curing light. Gel nails require ultraviolet (UV) light to cure. LEDs emit less UV radiation than a UV curing light. An LED light also cures faster, reducing your UV exposure.

Ask your nail stylist to skip trimming the cuticles. Cuticles are often trimmed when getting any type of manicure. That’s a problem. Cuticles protect your nails and the surrounding skin from infection. Trimming or cutting your cuticles makes it easier for bacteria and other germs to enter your body and cause infection. Nail infections can take a long time to go away.

Cut cuticles also tend to feel rough as they grow back, so a nail artist may still be able to trim your cuticles to keep them smooth.

Reserve artificial nails for special occasions. If you love the look of fake nails, buying them just for a special occasion can reduce nail problems. The time without artificial nails gives your nails a chance to repair themselves.

If you don’t wear artificial nails, a regular or French manicure can make your nails look fabulous.

“Acrylic” nails (liquid and powder) are the most common form of salon nail enhancement due to their ease of use, strength and durability. When a nail technician uses a file or drill that is too coarse for the natural nail, layers of the nail plate are removed, resulting in a delicate and thin natural nail. If a nail technician abuses “primer” – an adhesion promoter used with acrylic paints, it can cause sensitivity (stinging) and possible allergic reactions when in contact with the surrounding skin.

“Foundation” – a caustic chemical that can burn the skin. If a salon uses (prohibited) liquid MMA monomer instead of the approved liquid EMA monomer when making acrylics, this can create several possible complications (see EMA/MMA information below). When a nail technician removes the artificial product by mechanically squeezing it out of the natural nail with acrylic pliers, this unnecessarily removes the layers of the nail plate, leaving the natural nail fragile and thin

WHAT IS MMA?

Methyl methacrylate (MMA) is an ingredient commonly used in early “acrylic” nail services. In the early 1970s, the FDA received numerous personal injury complaints related to the use of acrylic monomer formulated with MMA. Reports have included severe nail damage or loss, contact dermatitis, soreness and infection from fractures caused by the rigidly adherent MMA acrylic. By the late 1970s, the FDA had taken action against several manufacturers who were marketing liquid MMA monomers. Most professional nail makers use a product called EMA, or ethyl methacrylate, which has been declared safe and approved for use in the beauty industry. What are the health risks associated with MMA products?

MMA-related ailments range from skin allergies to permanent nail plate loss. Here are the most common complaints that prompted the FDA to take action:

Nail Infections – The surface adhesion of MMA acrylic is so strong that even slight trauma will cause the nail to break and lift off the nail bed. which can lead to infection and/or loss of the nail plate. Ironically, it is the strength of the “Acrylic” that draws some users. While MMA used in the medical and dental industries provides excellent adhesion to bone, it is not suitable or safe for use on the softer nail tissue.

Respiratory Issues: Eye, nose and throat irritation – Without proper extraction, MMA fumes can cause sinus problems and tingling in the extremities.

Permanent Nail Deformities – The extreme damage that can occur as a result of trauma can compromise the matrix (where the nail plate comes from) and cause total or partial permanent loss of the nail plate.

Severe Allergic Reactions – Repeated exposure to MMA can result in severe allergic reactions. Redness, swelling, numbness and itching are common symptoms that can lead to blisters/open sores that can result in a permanent allergic reaction.

Is EMA really safe?

You will be pleased to know that ethyl methacrylate is one of the most studied monomers on earth. There is a vast body of scientific literature confirming the safety of this important substance. It is used in everything from household plastics to medical devices that are implanted in the body.

There is no evidence that EMA can affect or harm an unborn baby. The strange odor of the substance worries and frightens people. But smell has nothing to do with safety. Some very dangerous chemicals have no odor or even smell sweet and wonderful. For example, the vast majority of cosmetic-related allergic reactions are caused by fragrances in products. For this reason, it is foolish to assume that odorless or odorless = safe. It doesn’t! (For example – GASOLINE smells wonderful, but it is DEATHLY!)

Of course, you should still be careful and work safely. Working safely is important regardless of your job. Nail technicians should ensure they use adequate ventilation to control both dusts and fumes. Nothing in the world is 100% secure. Millions have died from too much water. Despite this, we know that water is safe to use. The same goes for nail enhancement products.

How can I say?

Since MMA is banned, you’re unlikely to find it on the ingredient label. However, it is usually not difficult to determine whether a product contains MMA. Here are three simple things to look out for: 1. Unusually strong or strange odor that doesn’t smell like other acrylic liquids. 2. Reinforcements that are extremely hard and very difficult to file, even with coarse abrasives. 3. Improvements that do not soak in acrylic removing solvents. Price discounts can also be an indicator of using MMA. MMA costs several times less than EMA. The last character in the list above is the most important indicator. Nail designers who come across artificial nails containing ingredients containing MMA are usually surprised to hear how difficult it is to remove the product. The products can only be removed by filing with a very coarse abrasive or burs, which usually leads to further damage to the client’s nail plates and nail beds.

Methyl methacrylate (MMA) is a monomer also known as methacrylic acid, methyl ester.

MMA is a key building block for acrylic-based polymers and has applications that include safety glazing, exterior paints, vinyl impact modifiers, adhesives, illuminated light displays and more.

In this article, we provide a general overview of this important monomer, covering everything from its polymerization to important safety and handling considerations. Here are 5 important facts about Methyl Methacrylate Monomer (MMA):

1. The Basics of Methyl Methacrylate

As previously mentioned, MMA forms the basis for many acrylate polymers and is a key comonomer in resin formulations for paints, coatings and adhesives. In free radical initiated copolymers, MMA increases the Tg (glass transition) and contributes to durability, strength, transparency, and UV and abrasion resistance.

The chemical structure of MMA is shown below.

Here is some other important information about methyl methacrylate:

CAS Number 80-62-6 EINECS Number 201-297-1 Molecular Formula C 5 H 8 O 2 Molecular Weight 100.12 Melting Point -48°C (-54℉) Boiling Point 101°C (214℉) Flash Point 2°C ( 36℉)

Also note that the Tg for PMMA homopolymer is 105°C. In polymers, MMA contributes to durability, hardness, impact resistance, scratch resistance, and clarity.

2. The polymerisation of MMA

When it comes to polymerization, the range of acrylic copolymers that can be used with MMA is extensive. Monomer feeds can contain:

butyl acrylate.

2-ethylhexyl acrylate.

methyl methacrylate and other methacrylate esters.

acrylic acid and methacrylic acid.

styrene.

butadiene.

The monomer composition selected for copolymers is determined by the desired Tg of the resin, which ranges from -30°C to >30°C. The free radical reactivity ratios for MMA copolymer systems have been well studied and are available in the literature.

Please refer to the table below for reference Tg values ​​of some comonomers.

AA stable. MMA BA 2-EHA 87˚C 100˚C 105˚C -45˚C -55˚C

3. The Applications of Methyl Methacrylate

Methyl methacrylate monomer readily polymerizes to form high molecular weight homopolymers and copolymers.

The main application for MMA monomer is the formation of polymethyl methacrylate (PMMA) homopolymer for the manufacture of cast and extruded acrylic sheet. These cast PMMA film products exhibit good optical clarity, high transparency and UV stability. Applications include…

Shatterproof glass replacement.

security glazing.

Panels and light displays.

Outdoor lighting fixtures.

Sanitary fittings and components.

Outside of glazing and film applications, MMA is most commonly used as a comonomer in paints and coatings such as exterior paints and paper coatings. Polymers and copolymers of methyl methacrylate are in…

metal and foil coatings.

Industrial finishes.

floor polishes.

textile surfaces.

adhesives.

sealants.

Construction materials.

PVC impact modifiers.

Packaging.

inks.

These polymers are manufactured as aqueous, solvent and dispersion resins for these applications. Methyl methacrylate butadiene styrene (MBS) resins are used as impact modifiers for clear rigid PVC, an example of which would be bottles. In addition, MMA can partially replace styrene monomer in unsaturated polyester resins for better weather resistance and longer outdoor life.

For products such as signage, displays, bathtub surrounds, spas and table tops, as well as automotive lights and lighting fixtures, MMA polymerization can be cast into a solid shape.

Applications also include technical adhesives. These are liquid, reactive, permanent adhesives for bonding various substrates and they are made from MMA monomer with PMMA. Thin, fast-curing MMA reactive resin systems are ideal for sealing and filling cracks and pores in concrete surfaces and structures.

Other uses of MMA copolymers include mining flocculants, soil stabilization polymers, waterproofing agents and oil field drilling fluids.

4. The composition of a methyl methacrylate emulsion

To give an example of a methyl methacrylate application, we have included an example of an emulsion composition with MMA.

Below is a typical paint formulation using MMA monomer in a copolymer.

5. Safety and handling for MMA

When handling methyl methacrylate, paying special attention to safety is crucial for several reasons.

MMA is a flammable, colorless liquid that melts at -48°C and boils at 101°C. While MMA is soluble in most organic solvents, it is insoluble in water.

Aside from being flammable, direct contact with MMA can cause irritation of the eyes, skin, nose and throat. Methyl methacrylate is considered a skin sensitizer and can cause an allergic reaction on contact, where future exposures can cause itching and a rash.

More seriously, inhaling MMA vapor or mist can irritate the nose, throat, and lungs and can be fatal in high concentrations.

Because MMA can homopolymerize violently and generate significant heat and pressure, MMA is only provided in a stabilized form. To ensure the stabilizer of MMA can work effectively, it is important to store MMA under air and replenish the dissolved oxygen.

To obtain a Safety Data Sheet (SDS) and other MMA handling information please contact or telephone us. At Gantrade Corporation, we encourage our customers to obtain a thorough understanding of the health, safety, environmental and regulatory information on our products before handling.

Personally, my nails are in better shape since I switched nail technicians. The first time she put her hands on my nails she said she had to start over because she didn’t want to work over other people’s “work”. Fair enough. So we started with a blank canvas, which in the nail world means vacuuming off the acrylics and shaving off the tips. Unfortunately, the nail salon I’ve been going to for years used fake products even though I paid the maximum amount (insert emoji vape face).

Methyl methacrylate, or MMA, is the liquid acid used to activate the acrylic powder so it melts onto your nails — and it’s super dangerous to your nails, too. However, many salons are still using MMA and clients have NO idea. Here’s what you need to know about MMA acrylic powder and its safer alternative, EMA.

1. MMA acrylic is dangerous for the nail and the skin around the nail. When used, it can yellow the natural nail, cause permanent nail loss, numb the nail and the skin around it, and cause irritation and air blockages. MMA creates super tough nail enhancements that won’t break. However, when pinching the nail, the natural nail breaks first, causing even more painful damage under the MMA acrylic.

2. MMA was introduced to the nail industry in the 1970s when dentists used the same powder to make porcelain dentures. It can also be found in plastic. However, by the late 1970s, numerous complaints were being filed with the FDA about this powder’s horrific effects on skin, and thus it became “somewhat” illegal. I’m saying something because nail salons still use MMA today as it’s the cheaper route.

3. MMA acrylic powder reacts differently to everyone. For example, when I get my nails done with MMA, my nails feel super tight and slightly swollen, like tight braids waiting to be loosened. Why did I have someone who might not even be licensed put this on my nails? I didn’t know any better!

The tension I experienced with every fresh set was my skin reacting to chemicals that wouldn’t let your nails breathe, which are the strong chemicals used to make synthetics. This is a common side effect that most people put up with on a regular basis. Another side effect is swelling so severe that your cuticles can easily become infected with collections of pus if you are very sensitive. My nail technician actually told me that a young girl she knew didn’t know she was allergic to MMA and as soon as the acrylic hit her nail bed the reaction took hold and she had to be hospitalized. Shortly after her nails were done, they had to be cut off while the ambulance rushed to the hospital.

4. According to the FDA, MMA is a dangerous chemical that can cause miscarriage. The dust from the acrylic powder is also a problem. MMA is difficult to file and shape, creating a lot of dust when the nail technician uses a drill. This makes MMA unsafe to use as it cannot adhere well to the nail plate, often causing denting and thinning or no natural nail at all.

6. When MMA sucks up your natural nails it looks like gooey melted glue and smells so bad. The smell lingers even when exposed. If you walk past some of these gourmet salons, you can smell what is being cooked from just a few meters away.

6. Unfortunately, and for cheap reasons, many nail salons in low-income areas still use MMA acrylic and no one seems to care. The fact that nail vendors are still selling MMA is ridiculous. It poses risks for the nail technician (who usually wears a mask to prevent inhaling the odor) and the nail wearer (damaging nail beds and yellowing nails).

7. EMA (ethyl methacrylate) is a much better type of acrylic liquid. In 1999, the Cosmetic Ingredient Review approved EMA as safe for use in nail products. The difference between MMA and EMA products is in the smell, the way they soak up your nail beds, the damage to your natural nails and the overall reaction.

If you are concerned that you have been exposed to MMA, the first step is to get it off your nails right away. Proper nail care requires a fresh set every month, so get EMA or a regular manicure.

Methyl methacrylate (MMA) is an adhesion promoter used in artificial nail products. It is found in nail preparations used in and around beauty salons across Australia. Nail kits sold at retail stores may also contain the chemical.

As an adhesion promoter, MMA hardens much faster and adheres more strongly to the nail than other products. It is also cheaper compared to other agents, for example ethyl methacrylate (EMA).

However, MMA use has been linked to adverse health effects, and MMA-based acrylic nails are tough, inflexible, and difficult to remove.

What are the health risks?

Industrial use of MMA is known to be irritating to the eyes, nose, throat and respiratory tract.

People who have been repeatedly exposed to significant levels of MMA often complain of:

sleepiness

carelessness

dizzy spells

trembling of the hands.

Repeated exposure to MMA can also cause skin sensitization or dermatitis, resulting in:

skin redness

itching

rash

Swelling.

Using MMA as a nail product can contribute to nail damage and deformity in nail growth.

While consumers using MMA-containing products may be at some risk for some of these side effects, the risk is much higher for nail designers, who are frequently and typically exposed to MMA-containing products in the course of their work. MMA is not banned in Australia as it is safe to use in other applications. The Department of Health strongly recommends that MMA products not be used in nail salons.

How do you know if a product contains MMA?

MMA is listed as an active ingredient on the product label.

It has a strong irritating chemical odor that doesn’t smell like other acrylic liquids.

The product cures much harder, feels less flexible and is very difficult to file with a nail file.

Acrylic nails containing MMA are extremely hard or virtually impossible to remove with regular solvents.

It is a much cheaper product (about a third of the price) compared to other acrylic nail products.

Consumers have the right to ask and be informed whether a product contains MMA.

Substitute for MMA

There are a number of alternatives to MMA including ethyl methacrylate (EMA), light cure gels, wraps and natural nail manicures.

Is MMA banned?

MMA is not a banned substance in Australia as MMA is safe to use.

However, it is important that employers, workers and customers are aware of the health risks associated with this product.
