What You'll Learn
Acetone-based nail polish removers
Acetone is a powerful solvent that can quickly and easily remove nail polish. It is the major solvent in nail polish removers and can break down the polymers present in nail paint. However, acetone is a harsh chemical that can dry out fingernails and skin, making it flaky. It can also penetrate through the skin and is known to be harmful to the liver. Prolonged exposure to acetone can dehydrate and weaken nails, so it is important to use it carefully and gently.
To use acetone-based nail polish removers effectively and safely, it is recommended to soak a cotton ball or pad in the remover and place it on the nail. You can secure it with aluminium foil and let it sit for a few minutes to help break down the nail polish. Then, gently rub or swipe the cotton ball to remove the dissolved polish. It is important to avoid the cuticles and skin around the nails as acetone can be drying and damaging to these areas.
Some acetone-based nail polish removers contain a small amount of glycerin to help counteract the drying effect of acetone. Glycerin is known to strengthen and lubricate fingernails. However, it is immiscible with acetone, so ethyl alcohol is added to solubilize the glycerin in the acetone. Ethyl alcohol itself is not a solvent for nail polish but aids in the solubilization process.
Another ingredient that is often used in combination with acetone is ethyl acetate. It is a stronger and less volatile solvent. Together, acetone and ethyl acetate can effectively remove nail polish, but they are also harsh on the skin and nails. As a result, many people are opting for acetone-free nail polish removers to prevent any damage to the skin and its natural barriers.
Overall, while acetone-based nail polish removers are effective at quickly removing nail polish, they can be harsh and drying. It is important to use them carefully and consider alternatives if you have dry, brittle nails or sensitive skin.

Non-acetone nail polish removers
While acetone is a highly effective way to remove nail polish, it is a harsh chemical that can dry out skin and nails and even damage the nail and cuticles. As a result, non-acetone nail polish removers have been developed, which are gentler on the skin. These typically contain less aggressive solvents like ethyl acetate, a colourless and fragrant liquid made from ethanol and acetic acid. Ethyl acetate is also flammable and is used as a solvent and in perfumes.
Non-acetone removers may also contain isopropyl alcohol and propylene carbonate. While these formulations are less drying than acetone, they can still have a drying effect, so some brands add moisturising agents like glycerin, panthenol and soy to their products. Soy-based nail polish removers, for example, can effectively remove natural nail polishes while promoting healthy and moisturised nails. These removers contain vitamins A, C and E, and are free from harsh acetates.
Some non-acetone nail polish removers are marketed as "natural" and biodegradable. However, it's important to note that even these products still use a solvent, they just don't use acetone. If you have strong health concerns about the chemicals used in nail polish removers, you may want to opt for one of these natural alternatives.
It's worth noting that non-acetone removers are less effective at removing nail polish than acetone. They require more effort to remove polish, especially darker colours, and won't work on shellac (no-chip) manicures.

Ethyl acetate as a substitute for acetone
Nail polish remover is an organic solvent used to remove nail polish from nails. Acetone is a common ingredient in nail polish removers. However, acetone has been known to have undesirable effects, such as drying out fingernails and harming the liver. As a result, some people may prefer to use alternative solvents, such as ethyl acetate, which is often used in combination with acetone.
Ethyl acetate is a less volatile solvent than acetone and is considered milder and less harsh on the skin. It is also a stronger solvent, which means it can be more effective at removing nail polish. However, some people find that they need to use more product and rub it in more when using ethyl acetate-based nail polish removers. This is because ethyl acetate is a weaker solvent than acetone. The efficiency of ethyl acetate also depends on the composition of the nail polish, with regular nail polishes responding similarly to acetone, but gel and acrylic polishes potentially responding differently.
Despite these differences in user experience, ethyl acetate is still a viable substitute for acetone in nail polish removers. It is important to note that ethyl acetate and acetone have different chemical properties, such as polarity, which may affect their performance in certain applications. For example, in silica gel column chromatography, substituting acetone with ethyl acetate may not yield the desired results due to differences in solubility and peak broadening, ultimately decreasing overall efficiency. However, in other applications such as hexane/ethyl acetate purification, acetone can be generally substituted.
When choosing a nail polish remover, consumers have the option to select products without certain chemicals. In addition to ethyl acetate, other alternative solvents to acetone include isopropyl acetone, MEK (Methyl Ethyl Ketone), and NMP (N-Methyl-2-Pyrrolidone). However, it is important to note that these alternative solvents may also have potential health risks. For example, isopropyl acetone has been associated with respiratory and eye irritation, headaches, and nausea in human studies. NMP has been linked to acute contact dermatitis, causing symptoms such as swelling and itching, and it is also a severe eye irritant. Therefore, it is important for consumers to carefully consider the ingredients in nail polish removers and opt for safer alternatives when possible.

Moisturising agents like glycerin or aloe vera
Nail polish removers generally come in two types: acetone-based and non-acetone. While acetone is a powerful solvent for removing nail polish, it has the undesirable side effect of drying out fingernails. To counteract this, some nail polish removers contain moisturising agents like glycerin or aloe vera.
Glycerin is a well-known humectant, meaning it locks in moisture, softening the skin and preventing it from drying out. It also has the added benefit of strengthening and lubricating fingernails.
Aloe vera is another excellent moisturising agent with anti-inflammatory properties. It helps with wound healing and skin regeneration, making it a great choice for those with sensitive skin.
In addition to their hydrating properties, both glycerin and aloe vera are useful in combating the drying effects of acetone and alcohol, which can be detrimental to nail health if used frequently.
Scout Cosmetics' nail polish remover, for example, contains both glycerin and aloe vera, as well as other moisturising agents, to ensure nails and cuticles stay hydrated during the polish removal process.
By including these moisturising agents, nail polish removers can help keep your nails healthier, especially with frequent use.

Potential health risks of ingredients
Acetone is a common ingredient in nail polish removers, acting as a solvent to break down nail polish. While it is not considered toxic and is not a registered carcinogen, it can be dangerous if ingested. It can also dehydrate the nail plate, cuticles, and surrounding skin, leading to dryness and irritation. Prolonged exposure to acetone may result in brittle nails and flaky, red, and irritated cuticles.
Ethyl acetate is another solvent found in nail polish removers, often used in combination with acetone. It is less volatile than acetone and helps to solubilize glycerin, an ingredient that strengthens and lubricates fingernails. While ethyl acetate is mostly non-toxic, chronic or high exposure may lead to irritant contact dermatitis, a skin reaction caused by damage to the outermost layer. Additionally, there are respiratory risks associated with ethyl acetate, especially for individuals regularly exposed, such as nail artists.
Butyl acetate is a similar ingredient to ethyl acetate and may be used interchangeably in nail polish removers. It is an effective antimicrobial agent, helping to prevent microbial growth in nail polish and nail polish removers.
Isopropyl alcohol is sometimes included in nail polish remover formulations, often in combination with ethyl acetate, to provide a gentler alternative to acetone. While it can be effective, it may not be suitable for all surfaces and materials due to its potential to damage certain coatings.
Overall, while these ingredients in nail polish removers may pose some potential health risks, the level of concern varies. Dermatologists and nail technicians emphasize that any chemical or mechanical process beyond simply trimming and buffing nails will cause some degree of damage. It is important to practice caution and moderation when using these products and to prioritize moisturizing after nail polish removal to mitigate potential negative effects.
