The smell of nail polish remover is due to acetone, a solvent that breaks down paint
The distinctive smell of nail polish remover is due to acetone, a solvent that breaks down paint. Acetone is a strong-smelling chemical found in nail polish remover and nail polish. It is used to break down the ingredients in paint, making it useful for thinning or removing paint from a surface. Given that nail polish is designed to stay on for a while, it requires a strong chemical like acetone to remove it effectively.
Acetone is deemed safe for short-term use and in well-ventilated spaces. However, it does have mild toxicity and can irritate the eyes and skin. Long-term exposure to acetone has resulted in kidney, liver, and nerve damage in animal studies. For most people, this is not a concern as their exposure to acetone is limited. Nevertheless, it is important to be cautious when using acetone, especially avoiding ingestion and ensuring proper ventilation during use.
The smell of acetone is sharp and chemical-like, and it can linger in indoor environments, requiring good ventilation to dissipate. Acetone is not only found in nail polish remover but also in household products, beauty products, and even naturally in our bodies. People with diabetes produce higher levels of acetone and may occasionally emit a smell similar to nail polish remover.
The glossy appearance of nail polish is often due to another chemical called camphor, which is also found in vapor rubs and nasal sprays. Camphor is less toxic than other nail polish ingredients but can still cause skin irritation, allergic reactions, nausea, dizziness, and headaches.
While some nail polish removers are labelled as "toxin-free," it is important to be cautious as mislabelling can occur, and even these products may contain high levels of toxic chemicals. Overall, it is important to be aware of the potential health risks associated with exposure to nail polish and its strong chemical smell.

Acetone is naturally occurring in our bodies, produced in larger amounts by people with diabetes
The distinctive smell of nail polish remover is due to acetone, a colourless, highly volatile, and flammable liquid with a pungent odour. Acetone is a ketone, a type of chemical compound produced and disposed of in the human body through normal metabolic processes. It is present naturally in the blood and urine in small quantities.
Acetone is produced in larger amounts by people with diabetes, particularly those with diabetic ketoacidosis. This occurs when the body cannot get energy from glucose and burns fat instead, creating a buildup of acids in the blood called ketones, which include acetone. Diabetic ketoacidosis can be dangerous, leading to a sharp and potentially fatal increase in the acidity of the blood. Other conditions that can cause a buildup of ketones include alcoholism and dietary factors such as fasting and high-fat, low-carbohydrate dieting.
The fruity scent of nail polish remover can be an indicator of high levels of ketones in the blood. People with diabetes who notice this smell may need to test their blood ketone levels and adjust their insulin dose accordingly. However, the smell can also be caused by external factors such as nail polish remover residue on towels or other surfaces.
While acetone is generally recognised as safe when used according to manufacturer instructions, long-term exposure can cause kidney, liver, and nerve damage in animals. It is important to use acetone in a well-ventilated space and avoid ingestion or inhalation.

Other chemicals in nail polish and removers include toxic toluene and phthalates
The characteristic smell of nail polish remover is due to acetone, a solvent that breaks down the ingredients in paint. While acetone is generally deemed safe, it does have mild toxicity and can irritate the eyes and skin. Most testing for acetone has been done on animals, and long-term exposure has resulted in kidney, liver, and nerve damage.
Nail polish and removers may contain other toxic chemicals, including toluene and phthalates. Toluene is a petrochemical solvent that gives off a sweet, pungent smell and is used to create a smooth application and finish. However, its fumes are highly toxic, and studies have shown that exposure can lead to neurological damage, decreased brain function, impaired breathing, hearing loss, and nausea. Toluene has been classified as toxic to the immune system, and its use has been restricted by the European Union in personal care products. In California, it is listed as a chemical harmful to fetal development.
Phthalates, such as dibutyl phthalate (DBP), are another group of toxic chemicals found in nail polish. They are known endocrine disruptors and can cause decreased fertility, hormonal disruption, bioaccumulation, and liver damage in animal studies. The European Union has banned DBP in cosmetic and personal care products, and multiple jurisdictions have classified it as a risk to the reproductive system.
Other toxic chemicals found in nail polish include formaldehyde, formaldehyde resin, and camphor. Formaldehyde is a known carcinogen, and exposure to larger doses can cause cancer of the throat, nose, and blood. It is also associated with asthma, neurotoxicity, and developmental toxicity. Camphor, while used as a topical remedy, can be toxic if consumed.
The potential health risks associated with these chemicals have led to a rise in "non-toxic" nail polish brands that market themselves as being "free" of certain ingredients. However, it is important to note that the exclusion of certain chemicals may not necessarily indicate a safer product, as the exact amount of chemical absorption and its negative health effects are not well established.

Triphenyl phosphate (TPP) is a hormone-disrupting chemical found in nearly 49% of nail polishes
The smell of nail polish remover is due to acetone, a solvent that breaks down the ingredients in paint. Acetone is naturally occurring in our bodies, and people with diabetes produce it in larger amounts, giving off a smell similar to nail polish remover.
Triphenyl phosphate (TPP), also known as TPHP, is a chemical used in plastics to improve flexibility and as a flame retardant. It is listed as an ingredient in nearly 49% of nail polishes. TPHP is a potential endocrine disruptor, which can affect hormones and reproductive health. It has been associated with altered thyroid hormone levels and decreased semen quality in humans, as well as altered sex hormone balance and disruptions of reproductive performance in animal studies.
TPHP exposure from nail polish occurs through dermal exposure and inhalation. Urinary metabolites of TPHP increased seven-fold following nail polish application, indicating that TPHP is absorbed into the body. However, it is important to note that data on the toxicity of TPHP in humans is scarce, and the health effects of TPHP are not yet fully understood.
The presence of TPHP in nail polish is concerning due to its potential health risks. As consumers, it is essential to be aware of the ingredients in the products we use and to make informed choices to protect our health. While the evidence is not conclusive, it is worth considering the potential risks associated with TPHP exposure and opting for nail polishes that do not contain this chemical.
Additionally, it is worth noting that some companies have made efforts to create effective nail polish removers with less toxic ingredients. These alternatives may be worth considering for those concerned about the potential health risks associated with traditional nail polish removers.

Painting nails indoors leaves a strong, long-lasting smell, despite toxin-free labels
Painting your nails indoors can leave a strong, long-lasting smell, even if the nail polish is labelled as toxin-free. This is due to the build-up of odours that develop within the airspace of the indoor environment, which can flood throughout the entire area. The chemical fumes from nail polish are considered toxic, as they are made up of chemicals that are known to be dangerous to the human body. These chemicals, such as acetone, toluene, and dibutyl phthalate (DBP), can travel through the air and lead to exposure through inhalation or ingestion, potentially causing eye, nerve, and lung damage.
While some nail polishes are labelled as "toxin-free", it is important to note that many of these products may still contain high levels of toxic chemicals and be mislabelled for consumers. Formaldehyde, toluene, and DBP are three key ingredients that have been targeted as potentially toxic. DBP, for example, is a hormone disruptor that is also found in children's toys. Its purpose in nail polish is to make it last longer.
The strong smell of nail polish can also be attributed to the use of nail polish remover, which can produce fumes that may be even more harmful to human health than nail polish itself. In addition, the smell will linger in spaces with poor ventilation and little airflow, settling onto surfaces in the home.
Some individuals may have a stronger sense of smell or a sensitivity to nail polish, which can make them more aware of the lingering odour. However, it is important to note that the effects of indoor nail painting can have long-lasting impacts on the odour within the airspace, leaving a strong smell that may be unpleasant or bothersome.
To mitigate the strong, long-lasting smell of indoor nail painting, it is recommended to use an air purifier to help combat the chemical odour in the air. While technologies like ozone, carbon, and ionizers have been used for odour removal, they may have flaws such as the inability to neutralize odours or the potential to emit dangerous byproducts.
