Nail polish remover is a common household product used to remove nail polish. It is typically composed of acetone, ethyl acetate, or a combination of the two, which are derived from non-renewable, petroleum-based sources. These organic solvents are effective at breaking down and dissolving the chemical bonds in nail polish, allowing for its easy removal. However, due to their inorganic nature and potential health and environmental concerns, there has been a growing interest in seeking more sustainable and eco-friendly alternatives. This includes exploring organic and natural options, such as plant-based solvents, as well as non-chemical solutions like press-on nails, which offer a salon-quality experience without the need for harsh removers.

What You'll Learn
Acetone is the major solvent in nail polish removers
Acetone is a clear, colourless, volatile liquid solvent with a somewhat fruity odour. It is the major solvent in nail polish removers, and it works by breaking down the polymers in nail polish, making it easy to wipe off. It is highly effective at removing tough, glittery polishes or gel nails. It is also the simplest and least expensive composition for nail polish remover, containing about 90% acetone and 10% water.
Acetone is a powerful ingredient, and its strength as a solvent means it can be harsh on the skin and nails, leading to dryness or irritation. It is also toxic, and ingesting it can cause an upset stomach, headache, dizziness, nausea, vomiting, difficulty breathing, low blood pressure, rapid heartbeat, loss of consciousness, and may even be fatal. It can also penetrate through the skin and is known to be harmful to the liver.
To avoid the harsh effects of acetone, non-acetone removers can be used, which are gentler on the nails but may take longer to dissolve the polish. The key active ingredient in non-acetone removers is usually ethyl acetate, which is made from ethanol and acetic acid. It is a solvent with a strong fruity odour and is also used in perfumes.
Other solvents used in nail polish removers include isopropyl acetone, methyl ethyl ketone, and n-methyl-pyrrolidone. However, these chemicals may cause reproductive harm and organ toxicity. N-Methyl-Pyrrolidone, for example, is prohibited for use in cosmetics in the European Union due to links to cancer and reproductive toxicity.

Acetone is derived from non-renewable, petroleum-based sources
Acetone, also known as dimethyl ketone or 2-propanone, is a colourless, highly volatile, and flammable liquid with a characteristic pungent odour. It is the major solvent in nail polish removers, and about 6.7 million tonnes were produced worldwide in 2010.
The cumene process accounts for approximately 83% of acetone production, with the remaining processes involving the direct oxidation of propylene (Wacker-Hoechst process) or the hydration of propylene to yield 2-propanol, which is then oxidized to acetone. Acetone can also be produced indirectly from propene through the hydration of propylene to 2-propanol, followed by oxidation. Additionally, acetone was previously produced through the dry distillation of acetates, such as calcium acetate in ketonic decarboxylation.
The shift towards petroleum-based production has raised sustainability concerns due to the non-renewable nature of these sources. With increasing pressure to adopt greener practices, the industry is exploring alternatives, and biotechnological advancements are paving the way for bio-acetone, which utilizes renewable resources.
While nail polish removers may contain additional ingredients, such as oils or fatty materials, acetone remains the primary solvent, and its production is closely tied to non-renewable, petroleum-based sources.

Acetone has an undesirable effect of drying out fingernails
Acetone is a common ingredient in nail polish removers. It is a powerful chemical solvent that can effectively break down nail polish. However, acetone has an undesirable side effect: it can dry out and damage fingernails and the skin around them.
Acetone is a simple and inexpensive ingredient, and a typical nail polish remover composition may contain about 90% acetone and 10% water. While it is an effective solvent for removing nail polish, acetone can also dissolve natural oils and moisture from the nails and the surrounding skin. This can lead to dryness, flaking, and irritation of the nails, cuticles, and skin.
The drying effect of acetone can make nails brittle and prone to peeling, splitting, and breakage. Prolonged exposure to acetone, such as during the removal of gel, SNS, or shellac manicures, has been associated with nail splitting (onychoschizia) and white discolouration (pseudo-leukonychia). It can also contribute to overall thinning and severe brittleness of the nails.
In addition to the undesirable effects on nail health, acetone can also be harmful if ingested or if there is high exposure. While small amounts used in nail polish removers are generally considered safe, acetone can be toxic in larger quantities or with prolonged exposure. It can cause skin irritation, redness, and cracking, and it is harmful to the liver.
To mitigate the drying effects of acetone on the fingernails, some nail polish remover formulations include additional ingredients such as oils or fatty materials. These additives help prevent nail dryness, but they may result in an unpleasant feel or undesirable colour changes in the formulation.

There are organic and natural alternatives to acetone-based removers
Nail polish removers are generally based on acetone, which is a simple, inexpensive, and effective solvent for removing nail polish. However, acetone has been known to have adverse effects on nail and skin health, causing dryness, brittleness, irritation, and even potential harm to the liver. As a result, there has been a push for organic and natural alternatives to acetone-based removers in the beauty industry.
One such alternative is ethyl alcohol, which can be used to remove any oil from the nail bed prior to applying polish. This helps to dry out the bed so that the varnish can bind effectively. Some nail polish removers also use ethyl alcohol in combination with acetone to help solubilize other ingredients in the formula.
There are also acetone-free nail polish removers available on the market that utilize different ingredients to effectively remove nail polish without the harsh effects of acetone. For example, Olive & June's Polish Remover Pot uses soybean and lavender essential oils to leave cuticles and nail beds hydrated and smooth while effectively removing polish. Static Nails also offers a 100% non-toxic remover that is formulated without scent and without the use of acetone, leaving nails with their natural oils intact.
For those seeking vegan and eco-friendly options, Zao's water-based nail polish remover is a great choice. It is formulated with organic ethyl lactate and organic bamboo water, which help to strengthen and fortify nails while gently removing polish. This remover is free from parabens, triclosan, phthalates, mineral oils, and artificial colours, and it comes in recyclable glass packaging. Another vegan and cruelty-free option is the French brand Manucurist, which offers an acetone-free remover with 97% bio-sourced ingredients, leaving nails hydrated and gentle.
In summary, while acetone-based nail polish removers are widely used due to their simplicity and cost-effectiveness, there are organic and natural alternatives available that provide effective removal without the harsh side effects associated with acetone. These alternatives prioritize nail and skin health, offering gentler formulas that nourish and hydrate while removing nail polish.

Acetone is harmful to the liver
Acetone is a chemical commonly found in nail polish removers. It is also a ketone produced by the body when it breaks down fat reserves. While acetone is generally recognised as safe, overexposure to it can be harmful.
Acetone is also known to cause fatty deposits in the liver. Autopsies of guinea pigs that died after inhaling high concentrations of acetone revealed fatty deposits in their livers. However, it is important to note that intermittent exposure of rats to high concentrations of acetone did not produce signs of liver toxicity.
While the effects of acetone on the liver are concerning, it is important to note that acetone is generally safe when used as directed. The majority of acetone-based products, such as nail polish removers, are designed for external use and are safe when used properly. However, inhaling or ingesting acetone can be dangerous and may lead to health problems, including liver damage.
To minimise the potential risks associated with acetone, it is important to follow safety guidelines when using acetone-based products. This includes ensuring proper ventilation, keeping lids tightly closed when not in use, and disposing of any acetone-soaked materials properly. By taking these precautions, individuals can help protect themselves from the potential harmful effects of acetone on the liver and other organs.
