What You'll Learn

Acetone is the likely cause of the nail polish remover smell
Acetone is a naturally occurring chemical in the human body, and it is also a common ingredient in nail polish remover. Acetone is a solvent that breaks down the ingredients in paint and nail polish, allowing for their removal from a surface. It has a strong, sharp, and unmistakable smell that is often associated with nail polish remover.
Acetone is also found in other products and can be released into the air through various sources, including new furniture, paint, cleaning products, and household products, which can result in a strong nail polish remover-like smell in an indoor environment. This off-gassing of volatile organic compounds (VOCs) can lead to a persistent acetone odour that may require proper ventilation or the use of air purifiers with activated carbon filters to eliminate.
Additionally, people with diabetes produce larger amounts of acetone, which may cause them to occasionally emit a body odour resembling nail polish remover. This is a natural occurrence and should not be a cause for concern. However, if the smell is accompanied by other symptoms or concerns, it is always advisable to consult a medical professional.
Furthermore, refrigerant leaks in air conditioners or refrigerators can also be a source of acetone odour. These appliances rely on refrigerants to maintain cool temperatures, and a leak can allow these chemicals to escape into the air, resulting in a sharp, chemical odour. In such cases, it is important to address the leak and seek professional assistance if needed.
While acetone is generally considered safe for nail polish removal when used appropriately and in well-ventilated spaces, long-term exposure has been associated with kidney, liver, and nerve damage in animal testing. Therefore, it is important to use acetone with caution and ensure proper ventilation to mitigate potential health risks.

Potential health risks of nail polish remover
Nail polish removers typically contain acetone as the main active ingredient. While acetone is considered safe 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 dizziness, headaches, irritated eyes, skin, throat, and nose, and in extreme cases, even damage to the liver and kidneys.
The FDA does not categorize acetone as a toxic ingredient. However, it does classify conventional nail polish remover as household hazardous waste since acetone makes the product flammable. Acetone is also a naturally occurring solvent, found in trees, plants, volcanic gases, and even the human body.
Other potential health risks associated with nail polish removers include the presence of other chemicals such as toluene, dibutyl phthalate (DBP), and formaldehyde, which are sometimes referred to as the "toxic trio." Toluene can cause dry or cracked skin, headaches, dizziness and numbness, while DBP can cause nausea and irritate the eyes, skin, nose, mouth, and throat. Formaldehyde has been recognized by the National Cancer Institute as a potential cancer-causing substance and is among the most common substances that cause allergic contact dermatitis.
The use of nail polish remover can also contribute to indoor air pollution, as the chemical fumes from nail polish removers are considered toxic. These fumes can build up indoors and cause adverse health effects, especially for those repeatedly exposed, such as manicurists and beauticians.
To minimize potential health risks, it is recommended to use non-acetone removers or natural alternatives, ensure proper ventilation during use, and avoid prolonged or excessive exposure to the product.

The smell could be due to a refrigerant leak
If you notice a nail polish remover smell, it could be due to a refrigerant leak in one of your appliances. Refrigerant leaks have been reported in dishwashers, refrigerators, wine fridges, air conditioners, and car AC units.
In one instance, a user reported a nail polish remover smell in their home, which was accompanied by issues with their dishwasher. An electrician confirmed that the dishwasher had "fried" inside. The user also owned a wine fridge and a regular-sized fridge/freezer, and suspected that the smell could be coming from one of these appliances.
Another user reported a similar issue with their car's AC unit, emitting a nail polish remover smell. A mechanic found that the cabin air filter was dirty and needed to be changed. The refrigerant level was also checked and refilled.
If you suspect a refrigerant leak, it is important to contact a professional technician to handle the issue. Refrigerant leaks can result in reduced temperature control and require proper disposal procedures.
It is worth noting that other sources have attributed nail polish remover smells to moldy fruit, particularly oranges, and pest control chemicals. However, the presence of mold or pest control chemicals does not exclude the possibility of a refrigerant leak. If you are experiencing persistent or strong nail polish remover smells, it is advisable to investigate multiple potential sources and seek professional assistance if needed.

Rotten oranges or fruit can cause the smell
It is unusual to smell like nail polish remover and could indicate an underlying health condition. Nail polish and nail polish remover contain a mix of chemicals that are potentially harmful to those exposed to them, including manicurists, beauticians, and those who regularly have their nails painted. One such chemical is acetone, which has a fruity scent.
If you notice that your breath or body odour smells like acetone or nail polish remover, it may be a sign of high levels of ketones in your blood. This can be caused by several factors, including:
Dietary Habits
A ketogenic or keto diet, which is high in fat, moderate in protein, and very low in carbohydrates, can cause a spike in ketones. This is because the body uses fat instead of carbohydrates for energy, leading to a buildup of ketones, including acetone, in the blood.
Alcohol Use
Heavy drinking can also cause a buildup of ketones in the blood, a condition known as alcoholic ketoacidosis. This usually occurs in conjunction with other factors such as frequent vomiting and a lack of food intake.
Diabetes
High levels of ketones in the blood can be a sign of diabetes, specifically diabetic ketoacidosis (DKA). This occurs when the body does not produce enough insulin or cannot use insulin effectively, leading to a buildup of glucose in the blood and a corresponding increase in ketone production. DKA can be life-threatening and requires immediate medical attention.
In addition to these causes, it is worth noting that rotten oranges or fruit can also cause a smell similar to nail polish remover. If you are noticing this smell on your body or breath, it is important to consider your health and seek medical advice if you are concerned or experiencing other symptoms.
It is important to note that while this answer focuses on the potential health implications of smelling like nail polish remover, there may be other environmental or external factors at play as well. If you are concerned about this issue, it is always recommended to consult with a healthcare professional for personalized advice and guidance.

The dangers of nail polish and its chemical composition
It is not normal to smell like nail polish remover, and it could be a sign of exposure to toxic chemicals. Nail polish contains a mix of chemicals that can be harmful to those exposed to it, especially with repeated exposure. These chemicals can be absorbed into the body and can cause adverse health effects.
Nail polish has been known to contain toxic and sensitizing components since the 1940s. While the formulations have undergone changes to address this issue, new components have also been found to be toxic and allergenic. One study found that applying nail polish allows a dangerous hormone-disrupting chemical to enter the body and trigger adverse health effects.
The chemical composition of nail polish includes triphenyl phosphate (TPP), a hormonal disruptor found in nearly 49% of nail polishes and treatments. Other toxic chemicals found in nail polishes and removers include Dibutyl Phthalate (DBP), an endocrine disruptor linked to fertility issues and birth defects, and toluene, which is responsible for creating a smooth application and finish. Toluene has a sweet, pungent smell and is considered toxic.
Other chemicals in nail polish with potential health risks include camphor, which can cause skin irritation, allergic reactions, nausea, dizziness, and headaches; xylene, which can irritate the skin, eyes, and respiratory tract and may be potentially carcinogenic; and ethyl tosylamide/epoxy resin, which may contribute to antibiotic resistance.
Additionally, sanitation is a significant concern with acrylic nail powder, as communal jars can become a reservoir for bacteria, fungi, and viruses. The harsh removal process of acrylic nails can also damage the nail plate and cuticle.
To reduce exposure to toxic chemicals in nail polish, some brands market themselves as "five-free," "seven-free," or "ten-free," indicating they are free from specific ingredients like formaldehyde, toluene, dibutyl phthalate, formaldehyde resin, and camphor. However, even "xxx-free" or "natural" products can still contain toxic chemicals, and the health benefits of these alternative formulations are uncertain.
