How To Keep Deodorant From Melting In Car? Best 51 Answer

June 11, 2021

Certain items like laptops, cameras, and travel bags should never be left in your car — at least if you ever plan to see them again. In addition to the risk of theft, there is also a risk of heat damage from solar radiation. Even on a comfortable 73-degree day, a car parked in direct sunlight can reach an internal temperature of 120 degrees Fahrenheit within an hour.

However, it’s not just the electronics that respond poorly to “hot box” conditions. Many common household items can be damaged – or worse – become a hazard when exposed to extreme heat. Read on to learn the 7 things you should never leave in a hot car.

1. Aerosol cans

Most aerosol cans should be stored in a ventilated room at temperatures below 120 degrees. In many parts of the country, the mercury can hit the 90s and 100s, so inside car temperatures will be even higher. The contents of aerosol cans, e.g. Things like those with hairspray, sunscreen, or spray paint are likely to expand when it’s hot.

This creates the possibility of an explosion, which at this point could prove dangerous or even fatal to anyone in the car. Clear your car of aerosol cans as soon as you get home so they are not forgotten.

2. Medication

As you most likely know, many drugs need to be stored at room temperature to be fully effective. Therefore, leaving them in a hot car for a long time is not optimal, as the effectiveness of the drug may decrease. Creams and ointments can also melt. Try to schedule your pharmacy pickup at the end of your errand run, just before you head home.

3. Sunscreen

Like medication, sunscreen does not tolerate well if left in a hot vehicle. Extreme temperatures can cause the formula to be less effective and the ingredients to separate and potentially leak. If you like keeping sunscreen handy in your car, but don’t want an oily mess all over the interior, try a mineral powder sunscreen that comes with a brush. This way you avoid messy spills while protecting your skin from the sun’s harmful rays.

4. Hand Sanitizer

According to stories online, hand sanitizer can explode if left in a hot car. While alcohol-based formulas can explode or ignite if exposed to flame, the high temperatures inside a car make this unlikely. Several studies have shown that the maximum temperature inside a vehicle left in direct sunlight for an hour would reach 160 degrees Fahrenheit.

While the alcohol in the disinfectant would have to reach 600 degrees to ignite itself. However, as with other materials, heat can reduce or destroy the effectiveness of the product.

5. Food

Food can spoil quickly in extreme heat. “Meltables” like chocolate and ice cream come to mind, but any type of perishable food is unfit for consumption if left in the car for an extended period of time. As with picking up medication, you drive straight home after shopping. Are you planning a picnic? Pack your treats in a cooler bag and remove it from the car immediately after parking.

6. Drinks

Your favorite beverages are also susceptible. Nobody wants to drink warm soda, beer or wine on a hot day, so put bottles or cans in a cooler filled with ice. Lukewarm water isn’t tasty either, but plastic water bottles also pose another problem. The chemicals in plastic can leach into drinking water in extreme heat. Instead, decant your H2O into a thermal bottle and enjoy cold, fresh water when you need it most.

7. Glasses

If you must wear glasses to see clearly, hopefully you’ll have them on your face when you get out of the car. But spare sets and of course sunglasses are often left behind. If the glasses are left in the car for a long time, they become too hot to wear and you run the risk of the sun distorting the frame. Keep all spares in a case and consider investing in a chain to keep the sunglasses around your neck.

Conclusion: It’s best not to leave anything in the car on a hot day, but sometimes you have no other choice. If this is the case, try to mitigate the heat by parking in the shade if possible. And consider investing in a sunshade for your windshield.

How hot does a car get in the sun? Most drivers have no idea. But we all know the dangers of sitting in a hot car. In addition to the general ailments, people suffer from heat-related illnesses. Heatstroke, a dangerous and potentially fatal heat-related illness, can occur quickly in a hot vehicle. In 2016, there were 39 heatstroke deaths in children left in cars in the United States. Most hot car deaths are linked to heat stroke.

On a hot summer day, the inside temperature of a car can be up to thirty degrees Celsius higher than the outside temperature. Common sense dictates that we should never leave other people (especially babies and the elderly) in parked cars as we cannot endure hot car temperatures. What other things shouldn’t we leave in a hot car? We will briefly discuss the most important ones to keep you and your loved ones safe and also to keep your valuables safe.

people and pets

First things first: people should never be left in a parked car, even if the chance of overheating is remote. Babies and the elderly are most vulnerable to this potential hazard. You should also never leave your pets in a parked car. No living being should be left in a parked car: this is the number one rule in preventing car heat deaths.

medication

If you check the labels on most medications, you’ll find that they’re meant to be stored in a cool, dry place. It would be best if you don’t take the risk of leaving them in a hot car. Too high a temperature can easily endanger your medicines.

to eat and drink

You should also not leave your food and drink in a parked hot car. Food can spoil quickly in extreme heat. Candy bars and ice cream are just the most prominent examples. All foods can go bad. Drinks can also be damaged if left in a hot car. When disembarking, remove all supplies from the vehicles.

batteries and electronics

Battery manufacturers warn against exposing them to excessive heat. Your car’s temperature can get hot and cause an explosion. It is also not advisable to leave electronics in the car. Except for those made explicitly for motor vehicles, electronics in a parked car are easily damaged.

plastic bottle

Plastic water bottles and food containers exposed to the extreme heat of packed vehicles release all manner of potentially harmful substances into their contents that can seriously affect your health.

lighters

Lighters explode in extreme temperatures. You can never tell how hot your parked car can get in the summer, so don’t take the risk.

suncream

In the summer, you need your sunscreen to hand. Understandably you often want to have it with you, but don’t leave it in your car. Exposure to excessive heat shortens the shelf life of sunscreen.

Plant

Plants are living beings too. They also die when exposed to excessive heat. Do not leave plants in a parked car, even for a few minutes. Younger plants are much more sensitive. Try to keep the temperature low even when being transported in a vehicle.

glasses

The heat from your hot car can warp the frame of your glasses, affecting fit and function. Extreme temperatures can even deform the lenses.

cosmetics

It’s understandable that you want to have your cosmetics close at hand, but you should never leave them in a parked car. Not only can extreme temperatures destroy their active ingredients, but they can also melt cosmetics and leave a big mess to clean up.

Your car can serve multiple purposes, but it’s not the right place to store things. Hot cars can lead to several ugly situations that are avoidable. The items discussed here should never be left in a packed hot vehicle.

4. Keep the windows open

Start driving, but leave the car windows open for a minute or two to allow all the hot air to escape, do this until the air coming out of the vents feels cooler than the outside temperature.

Unfortunately, most people get stuck in traffic when commuting, which doesn’t benefit airflow. If traffic is an ongoing concern, we strongly recommend investing in a flying car…

5. Close the window and switch to air recirculation

As soon as the air conditioning blows cold, close all windows and switch to (pre-cooled) forced air.

You can now open the upper air vents and adjust the airflow as needed.

More advanced climate control systems allow you to set and maintain a constant temperature inside the car.

Think about your car checks with Summer FORCES

Think of the ‘FORCES’ acronym and you will go a long way in ensuring your car is ready for any long journey.

F stands for FUEL

Make sure you have enough fuel for your trip. Cars use more fuel in heavy traffic and stop-start conditions that can occur regularly, especially in warm weather.

O stands for OIL

To avoid engine damage and a possible breakdown, remember to check your oil level and top up if necessary to reduce the chance of overheating on the road.

R stands for RUBBER

Your tires can tell you a lot about your car’s performance. If they don’t wear out evenly, the tire pressures may not match or there could be a fault in the steering.

Check that all four tires have at least 3mm tread and are inflated to the correct pressure – this is crucial to maintaining good grip in the wet and even on ice. Everything you need to know about checking your tires is in our guide to checking your tires with a short video.

Also, take a look at your wiper blades to make sure they’re cleaning the screen effectively and that the rubber isn’t damaged.

C stands for COOLANT

This is essential to ensure that the engine runs at the correct temperature. If it is not between the “min” and “max” values, this could indicate a problem. Therefore, contact a good workshop immediately.

E stands for ELECTRICAL

Your wipers help keep your windshield bug-free, and you need to turn on your lights during heavy downpours. The electrics also control your turn signals and windows, so check to make sure there aren’t any problems.

S stands for SCREEN WASH

Top up your washer fluid with a quality washer fluid, nobody wants bugs and seagull droppings on their windshield after a trip to the beach.

This will prevent your car from getting hot in the first place

1. Park out of direct sunlight

Parking in the shade — perhaps under a tree or under a canopy — is an easy way to keep your car from heating up. If you have a garage, use it. It keeps your car cool, clean and safe.

2. Use a windshield sunshade

A windshield sunshade keeps the sun’s rays out of the interior of your car – especially from touch points such as the steering wheel and shifter. They are available at most auto supply stores; simply stow the blind behind the sun visor when you park the car.

3. Leave the window (slightly) open

Leaving your windows slightly open allows air to circulate throughout the car — especially when the hot air rises inside. However, if your car is parked outside, we recommend leaving no more than a few inches of space between the top of the window and the door frame. You don’t want a potential thief to get inside. Also activate your alarm while the car is parked.

4. Cover your seats

Most modern car cabins are blacker than a coal mine, and that’s bad news for staying cool. Leather seats, in particular, can get uncomfortably hot and sticky — and can wear and crack with regular exposure to heat. Fitting light-colored seat covers is one solution, or you can opt for light-colored upholstery straight away. As a temporary measure, a towel spread over the seat will help keep you cool.

5. Wipe off hot surfaces

On very hot days, the interior door handles, steering wheel, shifter, and handbrake can become painfully hot. A damp wipe will help.

6. Maintain the air conditioner

Air conditioning maintenance is crucial to cool your car quickly and effectively. The cooling gas will normally be depleted over time and the belts may need to be tightened or replaced. Consult your vehicle manual and stick to the maintenance schedule.

Anhydrous stick deodorant has been known and used for many years. They offer many advantages over other deodorant dosage forms, especially over aerosols. These advantages are, for example, a high level of safety in use and storage, the absence of ozone-depleting propellants, simple and inexpensive packaging and good storage stability due to the absence of signs of drying out.

As a solidifying agent in anhydrous deodorant compositions, a combination of two types of wax is conventionally used, one of which has a relatively low melting point, i.e. less than 80°C, and the other has a high melting point, i.e. above 80°C.

The most common low melting point wax described in the literature and used in commercial products is stearyl alcohol, which has a melting point of 60°C.

The main disadvantages of combining a high melting point wax and a low melting point wax, such as stearyl alcohol, are the brittleness of the rods of the chopsticks, which reduces their durability, and the deposition on the skin of noticeable off-white marks that can later be transferred to clothing .

The Applicant has now found that it is possible to overcome these disadvantages by using as a means of solidifying anhydrous deodorant compositions a mixture of waxes free from waxes with low melting points, ie a mixture consisting only of waxes, all of which have melting points above 80°C.

The deodorant compositions of the present invention, solidified by such a combination of at least two waxes with high melting points, show an excellent durability in use and a lower lightening of the skin after application, while maintaining their cosmetic properties, in particular good spreading properties. maintained. such as smoothness, slip and wear.

The subject matter of the present invention is therefore a solid deodorant composition which, as solidifying agent, contains a mixture of waxes with melting points of more than 80° C. and at least one deodorant active ingredient.

In particular, the mixture of waxes of the present invention comprises:

at least one synthetic polyethylene wax with a melting point greater than 80°C, and

at least one wax of natural origin with a melting point above 80°C.

The polyethylene wax or waxes have the function of giving the product its necessary spreading, wear and sliding properties. The natural wax or waxes with high melting points, in combination with the first wax or waxes, reinforce the structure of the stick’s bar and contribute to the necessary rigidity to avoid stick disintegration.

The high melting point (>80°C) polyethylene wax used in the present invention is an ethylene homopolymer or a copolymer of ethylene and another copolymerizable monomer according to the following formula (I):

CH 2 =CHR (I)

wherein R is a linear or branched alkyl chain which may be interrupted by mono- or polyoxyalkylene units, an aryl or aralkyl radical or -CH 2 COOH or -CH 2 CH 2 OH radical.

The alkyl radicals mean in particular the methyl, ethyl, propyl, isopropyl, decyl, dodecyl and octadecyl radical.

The mono- or polyoxyalkylene units are preferably mono- or polyoxyethylene groups or mono- or polyoxypropylene groups.

The aryl group is preferably a phenyl or tolyl group.

The aralkyl radical is, for example, a benzyl or phenethyl radical.

The weight-average molar mass of the high-melting polyethylene wax according to the invention is preferably between about 400 and 1000, in particular between about 400 and 700 and is preferably about 500.

According to a preferred embodiment of the compositions according to the invention, the wax defined above is chosen from ethylene homopolymers, copolymers of ethylene and propylene, copolymers of ethylene and maleic anhydride or acid, or oxidized or ethoxylated polyethylenes.

Among the ethylene homopolymers that can be used according to the invention, those sold under the names Polywax 500, Polywax 655 and Polywax 1000 by the Petrolite company can be mentioned in particular.

Among the ethylene copolymers that can be used according to the invention, mention may be made of the ethylene-propylene copolymers sold under the name Petrolite® by the Petrolite company, and the ethylene-maleic anhydride copolymers sold under the name Ceramer are ® from the company Petrolite, the oxidized polyethylenes sold under the names Unilin® and Unicid® by the company Petrolite and the ethoxylated polyethylenes sold under the name Unithox® by the company Petrolite.

According to a particularly preferred embodiment of the invention, the polyethylene wax is an ethylene homopolymer wax.

In the anhydrous deodorant compositions of the present invention, the polyethylene wax described above is used in combination with at least one second wax which is a natural wax also having a melting point greater than 80°C. This natural wax is selected from mineral, fossil, animal or vegetable waxes or hydrogenated oils, fatty esters, fatty alcohols or polyethoxylated fatty alcohols solid at 25°C.

As examples of waxes of natural origin, microcrystalline waxes, ceresin, ozokerite, candelilla wax, carnauba wax, hydrogenated castor oil, hydrogenated palm oil or hydrogenated coconut oil can be used in the deodorant compositions of the present invention.

According to a preferred embodiment of the invention, the natural wax is an ozokerite with a high melting point. Ozokerite is a fossil hydrocarbon with a complex composition that corresponds to the solid residue from the evaporation of paraffin-rich petroleum.

A commercial ozokerite is the product Cerozo Blanche E626, a mixture of C 20-50 hydrocarbons sold by Barlocher.

The deodorant composition of the present invention comprises 5 to 20% by weight of the synthetic polyethylene wax and 2 to 20% by weight of the natural wax having a high melting point.

Preferably, the proportion of polyethylene wax is greater than that of natural wax and the weight ratio (polyethylene wax/natural wax) is in particular between 10/1 and 1/1 and in particular between 7/1 and 3/1.

The deodorant composition of the present invention comprises at least one deodorant active in addition to the mixture of high melting point waxes.

For the purposes of the present invention, a deodorant active ingredient is understood to mean any substance that is able to reduce the flow of sweat and/or to mask, improve or reduce the unpleasant odor resulting from the bacterial decomposition of human sweat.

It is, for example, an antiperspirant compound such as aluminum and/or zirconium salts, for example an aluminum hydroxychloride or an aluminum and zirconium hydroxychloride, or alum salts, a bacteriostatic agent, a bactericidal agent such as 2,4,4-trichloro-2-hydroxydiphenyl ether and ,7,11-trimethyldodeca-2,5,10-trienol, and various zinc salts, an odor absorbing agent such as sodium bicarbonate, an antioxidant such as butylated hydroxytoluene, or a mixture of these compounds and/or agents. 3,7,1-Trimethyldodeca-2,5,10-trienol is marketed, for example, under the name Farnesol® by the company Dragoco and 2,4,4-trichloro-2-hydroxydiphenyl ether under the name Irgacare® MP by the company Ciba -Geigy.

Among the aluminum salts, mention can be made of the product sold by the Reheis company under the name Reach 301 or by the Guilini Chemie company under the name Aloxicoll PF 40.

Aluminum and zirconium salts are marketed, for example, by the Reheis company under the name Reach A2P-908-SUF.

This deodorant active or mixture of deodorant actives is present at a level of from about 0.01% to 40% by weight of the total composition, preferably at a level of from about 0.05% to 25% by weight.

When the deodorant active is an aluminum hydroxychloride or an aluminum and zirconium hydroxychloride, it is present in a proportion of 2 to 30% by weight, preferably in a proportion of 5 to 25% by weight, based on the total weight of the composition present.

The solid deodorant composition of the present invention may additionally comprise one or more emollients. The function of these emollients is to improve the cosmetic properties of the final product, to promote good gliding of the stick piece over the skin and thus to facilitate the application of the deodorant composition. Examples of emollients are volatile silicones, such as the product sold under the name DC246 Fluid by Dow Corning, and non-volatile silicones, such as DC556, Polydecene B, sold by Dow Corning. the product Silkflo® S366 NF from Amoco, fatty acid esters such as the product sold by Unichema under the name Estol® 1517, fatty alcohols, ethoxylated and/or propoxylated surfactants or polyalkoxylated esters of glycol or PPG(14) butyl ether (Fluids AP from Union Carbide).

The content of plasticizers in the composition of the present invention is generally between 10 and 70% by weight, preferably between 20 and 60% by weight.

In addition, the deodorant composition according to the invention generally comprises one or more fillers incorporated in the fatty substance of the composition in the form of very fine particles. These fillers are chosen, for example, from talc, silicic acid, starch derivatives, clay or acrylate copolymers (Expansel 551 DE from Kemanord) and are generally present in a proportion of about 0.1 to 10% by weight relative to the total mass of the composition .

In addition, the deodorant composition according to the invention can contain other auxiliaries, such as fragrances and/or dyes. The person skilled in the art will of course take care to select this or these possible additional compounds in such a way that the advantageous properties inherent in the deodorant composition according to the invention are not or not significantly impaired by the intended addition or supplements.

The solid deodorant composition of the present invention is generally provided in the form of a stick deodorant.

Another object of the present invention is the use of the compositions described above to reduce the flow of perspiration and/or to mask, improve or reduce the unpleasant odor resulting from the bacterial decomposition of human perspiration.

This use consists in applying the solid deodorant composition, preferably daily, to the clean areas of the skin to be treated, preferably under the armpits.

The following non-limiting examples illustrate the present invention.

EXAMPLES 1 AND 2 AND COMPARATIVE EXAMPLES A AND B

Four solid deodorant compositions 1, 2, A and B shown in Table 1 below are prepared, differing essentially in the nature of the solidifying agents used.

Compositions 1 and 2 are compositions according to the invention containing two waxes with melting points above 80° C. as solidifying agents. Compositions A and B are prior art compositions containing, as solidifying agents, a high melting point (>80°C) wax and a low melting point (<80°C) wax, namely stearyl alcohol, which has a melting point of 60°C .

This test is carried out using an electronic error measuring device developed by OREAL RAD and manufactured by the company J. Bouleffroy (Estr{acute over (e)}es Saint-Denis, France). The sample to be tested is placed in a controlled chamber stabilized at 20 ± 1 °C for at least 16 hours. Immediately before the measurement, the sample is placed in the cup holder, which is adjusted so that the distance between the wire and the rod of the rod is 2-3 mm, and that the wire perpendicular to the longitudinal axis of the rod is exactly 10 mm from the base (cup ) remote from the latter. The minimum force (in g) required to cut through the rod with the specified standard wire is then measured. 2 – The static brittleness test consists in measuring the maximum force (in N) exerted by a standard tool (flat surface of a vernier caliper) that a sample can withstand under defined conditions before being split by this tool. This test is also carried out with the fracture measuring device used for the shear resistance measurement described above. The sample to be tested is placed in a controlled chamber stabilized at 20 ± 1 °C for at least 16 hours. Immediately before the measurement, it is inserted into the cup holder, which is adjusted so that the cut surface of the rod is parallel to the flat surface of the caliper at a distance of 3 mm from it. Then the minimum force (in N) required for the flat surface of the tongs pressed against the cut surface of the bar to split the latter is measured. The results of these tests, obtained for the two compositions of the invention (1 and 2) and the two comparative compositions (A and B), are shown in Table 2 below. TABLE 2 Composition Composition Composition Composition 1 2 A B Shear Strength (in g) 185 ± 5 154 ± 3 121 ± 4 not measurable (stick collapsed) Static Brittleness (in N) 6.9 ± 1.1 5.7 ± 0.3 4 .4 ± 0.2 not measurable (stick disintegrates) The values ​​obtained are the arithmetic means ± standard deviation calculated from 10 measurements. These results show that inventive compositions 1 and 2 have significantly better shear strength and static brittleness than compositions A and B, the latter being even too brittle to be measurable.

During a summer heatwave, a car parked in the sun or shade quickly builds up intense internal heat that can severely damage all kinds of items we normally carry with us.

Some of these will be very obvious. Most drivers are aware that leaving children or pets in a car can result in tragedy – breaking a window isn’t enough – but as you’ll see below there are many other things we keep in cars that do could be damaged by heat.

How quickly does a car interior heat up?

It doesn’t have to be a particularly hot environment for a car interior to suffer from the greenhouse effect. This is where the sun’s energy enters the car and begins to heat solid objects such as the dashboard and seats. These in turn begin to radiate heat – but this heat cannot escape through the windows.

With outside temperatures of 16°C, a car interior can heat up to 38°C (100°F). Weather experts say that when the outside temperature is 30°C, inside the car it quickly reaches 60°C. Stanford University School of Medicine conducted studies that showed that 80% of the average temperature rise occurred within 30 minutes of parking the car.

1. Pets

It is clearly unacceptable to leave dogs or other animals in a car when the interior reaches the temperatures described above, but research in 2014 by Dogs Trust, the UK’s largest dog charity, showed that more than one of ten people know of a dog that does this was injured in a parked car in hot weather. It states that less than 20 minutes in a hot car can kill a dog if its body temperature exceeds 41°C.

The RSPCA adds that if it’s 22°C outside in a car, it can reach 47°C in an hour. Both organizations say it is still very dangerous for dogs, even if the windows are left open (Dogs Trust claim this has no significant impact) or the car is parked in the shade.

If you see an animal in a hot car and are showing signs of heat stroke, the RSPCA recommends calling 999 as it is not authorized to enter and while you wait you should take photos/video as evidence. Do not attempt to break into the car unless you believe the owner of the property you are damaging would consent to the damage if they knew the circumstances, otherwise it could be classified as property damage.

2 children

It seems unbelievable, but children die in hot cars: an average of 38 a year in America. In 2010, Reggie McKinnon made headlines after the death of his 17-month-old daughter, Payton. The Floridian had left work to take her to the doctor, then returned to the office, but while driving he had forgotten that Payton was sleeping in her booster seat in the back of his Ford Explorer. McKinnon didn’t realize his mistake until three hours later, when he returned to his car at the end of the workday.

In the UK, where it is proportionately cooler, such tragedies are almost unknown – when Driving.co.uk asked, the Royal Society for the Prevention of Accidents could not recall any cases. But on hot days (temperatures are expected to hit a record 41C this week), parents and guardians should be vigilant.

Activists say visual reminders can help, e.g. For example, leaving a teddy bear in the car seat when not in use and putting it in the front seat when you buckle up a child.

3. Mineral water

It makes sense to have a bottle of water in the car during a heat wave. However, there are widespread health concerns about the use of bisphenol A and phthalates in plastics, chemicals that act as binders and make plastics flexible. If water in plastic bottles is left in a hot car, these agents can get into the water.

4. Smartphones and other battery powered devices

If you’ve left a modern smartphone in the sun for even a short time, it’s likely warned you to put it in a shady spot and let it cool down. The battery and processing chips generate enough heat to overheat a smartphone at normal temperatures. So exposing it above 40C doesn’t help.

Any other electronic device that contains a battery is the same, ie tablets, portable DVD players, MP3 players, cameras and more.

5. Sunscreen / Sunscreen

Ironically, the very thing we need to protect ourselves from the sun’s damaging effects can break in a hot car. The active ingredients contained in sunscreens can be degraded as temperatures rise in the car and in the packaging.

In some cases, sunscreen bottles can explode and leave a nasty mess that’s fiendishly difficult to clean off upholstery.

6. Aerosol canister

It might leave you smelling fresh or save a bad case of a bed headache, but keeping a can of deodorant or hairspray in the car isn’t a good idea in hot weather. As soon as temperatures reach around 48 °C, the pressure inside the canister rises to the point where it explodes, experts say.

7. Wine

It’s good to be organized and make good on the promise to bring home a nice bottle of rosé wine. But don’t buy it in the morning and leave it in the car or you might end up spitting the first bite down the sink. If wine gets too hot, aging and flavor can change, wine connoisseurs say.

Of more concern are studies showing that excessive heat exposure can lead to the formation of ethyl carbamate (EC), which could prove to be a carcinogen. Delicious.

8. Sunglasses

It’s annoying enough when you lose a nice pair of sunglasses. However, it might be a mistake to leave them in the car for safekeeping, as plastic frames can warp and discolour, and lenses can warp.

9. Medication

Some medications, such as antibiotics, should be stored in the refrigerator. Other everyday medicines, including Piriton and children’s treatments like Calpol and Nurofen, shouldn’t be exposed to temperatures above 25°C, the manufacturers say.

And if you carry or use adrenaline syringes like EpiPens, be aware that they will also deplete in hot cars. Which of course is a matter of life and death.

10. Lipstick

At nearly £30 for a Chanel lipstick, you’d kick yourself for leaving makeup in the car. It melts just above room temperature, so it doesn’t stand much of a chance in a muggy car.

11. Cans for carbonated drinks

Who hasn’t opened a can of soda after it’s been in the car while driving, only to have it splatter all over the place? Unfortunately, that’s the least of a problem in hot weather: It’s well documented that soda cans explode in hot weather and cover a car interior – which is a particular problem with sticky sugary drinks. Even orange juice can explode if left in the car for a long time.

12. Disposable lighters

Another exploding container, disposable lighters have been known to shatter windshields after exploding in hot cars. Take this with you when you exit the vehicle.

Yes. I’m actually talking about deodorant. On a boat. When it’s hot outside.

Seems like a stupid topic. Unless you had this problem. . .

When we bought our first ride boat over 10 years ago, one of our first “crisis moments” was when we discovered our deodorant stick had melted in the Mexican summer heat. And it seeped all over the shelf in the locker. Yuck! A mess to clean up and no deodorant to apply.

We had boarded less than a day ago and we were already realizing that there were problems with life on board that we would never have dared to dream of.

The solution turned out to be pretty simple: instead of buying stick deodorant, we started using roll-on. Because it is designed as a liquid, it is not affected by heat.

It’s silly stuff like melting deodorant that makes the first year of cruising seem like a straight-line learning curve. It really is easier!
