The Chemistry Of Nail Polish Remover

what nail polish remover made of

Nail polish remover is an organic solvent used to remove nail polish. It comes in two types: acetone-based and non-acetone-based. Acetone is the most common and powerful ingredient in nail polish removers, but it can be harsh on nails and skin, leading to dryness and brittle nails if used frequently. It is also toxic and flammable. Non-acetone removers, such as those with ethyl acetate, are gentler and cause less dryness, but they may take longer to work and may struggle with tougher polishes.

Acetone-based nail polish removers

Acetone-based removers are best for removing stubborn or thick polishes, including gel, shellac, or glitter. They are also suitable for removing nail polish from natural nails as they can weaken and cause nail extensions to separate from the natural nail.

The simplest and least expensive acetone-based nail polish removers contain about 90% acetone and 10% water. However, acetone has the undesirable side effect of drying out fingernails and can be harsh on the skin, often leading to dryness and brittle nails if used frequently. To counteract this, some acetone-based removers include moisturizing agents such as oils, fatty materials, castor oil, lanolin, glycerin, or aloe vera.

Other ingredients found in acetone-based nail polish removers include ethyl acetate, which is a solvent used in combination with acetone, and ethyl alcohol, which helps solubilize the glycerin with the acetone.

While acetone-based nail polish removers are effective, exposure to acetone can cause side effects such as irritation to the eyes, nose, and throat, as well as headaches, nausea, vomiting, dizziness, and lightheadedness in high concentrations. It is important to use acetone-based removers in a well-ventilated area to avoid inhaling the fumes. Additionally, acetone is flammable, so it should not be used near an open flame.

Non-acetone nail polish removers

The main ingredient in non-acetone nail polish removers is ethyl acetate. This is a gentler solvent compared to acetone but is still effective at dissolving nail polish. Ethyl acetate softens and dissolves the film-forming agents in nail polish, although it may take a bit longer to remove tougher polish like dark colours or glitter.

Ethyl acetate is made from ethanol and acetic acid and has a strong fruity odour. It can also be used in combination with acetone. Ethyl alcohol is often added to non-acetone removers to help solubilize glycerin with the ethyl acetate. This alcohol may be pure or diluted with water.

Glycerin is also sometimes included in non-acetone removers to counteract the drying effects of solvents. It helps to moisturize, strengthen, and lubricate fingernails. Other moisturizing agents that can be added include aloe vera.

Other ingredients found in non-acetone nail polish removers include isopropyl alcohol, which is a secondary solvent that assists in the breakdown process of dissolving nail polish. It works to evaporate quickly, speeding up the drying process. However, like acetone, isopropyl alcohol can be drying if used frequently.

Some non-acetone nail polish removers may also contain harmful chemicals such as isopropyl acetone, MEK, and NMP. These chemicals can cause respiratory and eye irritation, headaches, nausea, and sore throats. N-Methyl-Pyrrolidone, in particular, is prohibited for use in cosmetics in the European Union due to links to cancer and reproductive toxicity.

Potential health risks of acetone

Acetone is a common ingredient in nail polish removers. It is highly effective and works quickly to dissolve nail polish. However, acetone is harsh on nails and skin, often leading to dryness and brittle nails if used frequently. It can also cause respiratory and eye irritation, headaches, nausea, and sore throats.

Acetone is a potential health risk for those who work with it regularly, such as nail salon workers. Inhalation of acetone can cause a sore throat or cough, and it is highly flammable. It is important to use proper ventilation and follow safety procedures when working with acetone to keep exposure levels below safety limits.

Acetone has been studied for its potential health effects on humans and animals. Some studies have found that exposure to acetone can cause degenerative changes in the skin, decreased protein synthesis, and an increased risk of unspecified skin conditions. However, other studies have shown that acetone does not appear to be toxic to the lungs when administered orally to animals.

In the European Union, isopropyl acetone, a type of acetone used in nail polish removers, is restricted to low doses in workplace environments. N-Methyl-Pyrrolidone (NMP), another solvent used in nail polish removers, is prohibited for use in cosmetics in the European Union due to links to cancer, mutagenicity, and reproductive toxicity. It is important for consumers to be aware of the potential health risks associated with the use of acetone-based nail polish removers and to choose products that are safe for their health.

To summarize, acetone is a powerful and effective ingredient in nail polish removers, but it can pose potential health risks, particularly with frequent or prolonged exposure. It is important to be informed about the ingredients in nail polish removers and their potential effects on health, and to take appropriate precautions when using or handling these products.

Other harmful ingredients to avoid

Nail polish removers generally come in two types: acetone-based and non-acetone. While acetone is a safe ingredient to use in moderate quantities, over-exposure or sensitivity to this ingredient can cause an allergic reaction. Prolonged or excessive exposure to acetone can cause symptoms such as respiratory and/or eye irritation, headaches, nausea, sore throat, and weakness. To avoid these side effects, it is recommended to always use nail polish remover in a well-ventilated area. Non-acetone removers, on the other hand, are a gentler option and can help prevent adverse skin reactions like contact dermatitis. However, they may take longer to work and might struggle with tougher polishes or artificial nails.

  • Ethyl tosylamide/epoxy resin: While rated as a low hazard by the EWG, this ingredient is an antibiotic and could contribute to antibiotic resistance.
  • Lead: Lead has been linked to a wide range of harmful health effects, including disruption of the HPA axis and brain and kidney damage.
  • Hydroquinone monomethyl ether (MEHQ/HQ): This ingredient can cause skin and eye irritation.
  • Methylisothiazolinone (MIT) and methylchloroisothiazolinone (CMIT): These preservatives have been linked to lung toxicity, allergic reactions, and possible neurotoxicity.
  • Parabens: Parabens are common preservatives that act as endocrine disruptors, mimicking estrogen in the body.
  • Isopropyl acetone, MEK, and NMP: These solvents used in nail polish removers can have harmful effects. Isopropyl acetone can cause respiratory and eye irritation, headaches, nausea, sore throat, and weakness. MEK has been linked to elevated risks for multiple myeloma in women with higher exposures. NMP is linked to cancer, mutagenicity, and reproductive toxicity.

It is important to prioritize the quality of ingredients in nail care products and choose non-toxic alternatives whenever possible. Unfortunately, nail polish companies are not required to list their ingredients, making it challenging to know exactly what we are putting on our bodies. Look for brands that not only list the ingredients they omit but also disclose all the ingredients they use, such as YAPA, a non-toxic, vegan, cruelty-free, and gluten-free option.

Moisturizing agents in removers

Acetone is the most common and powerful ingredient in nail polish removers. It is a strong solvent that breaks down resins and film-formers in nail polish, allowing it to be wiped away. However, acetone can be harsh on nails and skin, often leading to dryness and brittle nails if used frequently.

Non-acetone removers, such as those containing ethyl acetate, are gentler alternatives that cause less dryness. These removers may also contain moisturizing agents like glycerin, aloe vera, and vitamin E to combat the drying effects of solvents and keep nails and cuticles hydrated.

Glycerin and aloe vera are common moisturizing agents in nail polish removers. Glycerin is a humectant, meaning it helps lock in moisture and prevents water loss from the skin. Aloe vera has similar moisturizing properties and is also rich in vitamins and minerals, which can nourish the nails and cuticles.

Vitamin E is another important moisturizing agent in some removers. It helps to nourish and protect the nails and cuticles, promoting healthy nail growth.

Some companies offer soy-based nail polish removers, which are free from harsh chemicals and enriched with vitamins to nourish the nails. These removers are much gentler but may not be as effective on all types of polish.

It is important to note that while moisturizing agents can help combat dryness, frequent use of nail polish remover, especially those containing acetone, can still lead to dry and brittle nails. It is recommended to limit exposure to nail polish remover, moisturize after use, and use a strengthening base coat to protect the nails.
