Several sources discuss the possibility of mixing nail polish remover with ATF (Automatic Transmission Fluid). Nail polish remover typically contains acetone, which is also sold separately and is often combined with ATF to create a penetrating oil. However, some users have reported issues with mixing ATF and acetone, with the two liquids separating into two distinct layers. This separation may be due to phase partitioning, a common industrial phenomenon where certain compounds segregate into two phases. While some suggest shaking the mixture before use, others recommend avoiding this combination altogether due to acetone's high vaporization rate, flammability, and potential health hazards.

What You'll Learn

Acetone is a primary component of nail polish remover
Acetone is a colourless liquid solvent that is commonly used as a nail polish remover. It is a simple ketone with the chemical formula (CH3)2CO. Acetone is an excellent solvent for organic compounds due to its carbonyl group (C=O). It quickly breaks down substances like paint, varnish, or grease, making it ideal for removing nail polish.
Acetone is a primary ingredient in traditional nail polish removers, paired with a fatty material like lanolin or caster oil. It works by breaking apart the nail varnish and stripping it from the nail plate surface. While acetone is effective at removing nail polish, it can also dehydrate the nail plate, cuticles, and surrounding skin. Prolonged exposure can lead to nail splitting, white discolouration, thinning, and severe brittleness.
Despite these potential side effects, acetone is not considered toxic or carcinogenic. The US Food and Drug Administration (FDA) has deemed it safe in adhesives and food contact coatings. However, ingestion of acetone can be dangerous, and proper handling is important. Acetone is also flammable and can attack rubber, so it should be used with caution and in appropriate settings.
Acetone has a wide range of applications beyond nail polish removal. It is used in the production of various chemicals, including methacrylates for adhesives and bathtubs. It is also employed in the food industry as a flavouring agent in small quantities. In electronics, acetone is useful for cleaning PCBs and preparing semiconductors. Additionally, it acts as a solvent in the rubber industry, aiding in the vulcanization process.
While acetone has multiple uses, it is important to note that it should not be mixed with certain substances, such as ATF (Automatic Transmission Fluid), as they do not combine effectively. Acetone is a versatile and valuable chemical, but understanding its properties and potential risks is crucial for safe and proper utilisation.

Acetone and ATF do not mix well
Acetone and ATF (Automatic Transmission Fluid) do not mix well. Several users have reported that the two liquids separate into two distinct layers, with the thinner acetone floating on top of the denser ATF. This behaviour is similar to the immiscibility of oil and water. The separation of layers occurs even after vigorous shaking, suggesting that acetone and ATF are not completely soluble in each other.
One user observed that the acetone and ATF mixture turned very dark, nearly black, over time. This discolouration could be due to the oxidation of ATF, as it is known to darken with prolonged exposure to air. Additionally, acetone has a high vaporization rate and is flammable, which can lead to an explosion or corrosion of parts if used in an enclosed space. Therefore, it is not recommended to mix acetone and ATF, especially in a closed garage.
Nail polish remover is often acetone-based, and some people have attempted to use it in place of pure acetone to mix with ATF. However, nail polish remover typically contains only about 40% acetone, along with water, alcohol, and glycerin. These additional components may further hinder the mixing of acetone and ATF, as they are unlikely to carry any lubricant. Therefore, using pure acetone is preferable if one intends to create a penetrating oil by mixing it with ATF.
While the acetone and ATF mixture may have some efficacy as a penetrating oil due to phase partitioning, it is not a stable mixture and requires constant shaking during use. Overall, the immiscibility of acetone and ATF, along with the potential safety hazards of acetone, make it challenging to work with this combination. Alternative penetrating oils, such as PB Blaster or Kroil, may be more effective and safer options.
It is important to note that any experiments with chemicals should be conducted with proper safety equipment and precautions. Acetone, in particular, should be handled with chemical-resistant gloves, as it can facilitate skin penetration by other compounds.

Acetone is a carrier that facilitates skin penetration
Acetone is a chemical commonly used in nail polish removers. It is also used in other household products, such as lacquer, varnishes, and paint removers. It is typically safe to use in moderate amounts, but prolonged exposure or large quantities can lead to negative health effects. For instance, acetone can cause skin dryness, irritation, and cracking, also known as dermatitis. In severe cases, long-term exposure to acetone may result in kidney, liver, and nerve damage.
In addition to its use in cosmetics, acetone is also employed in industrial applications. It is used for cleaning or degreasing large machines and creating products. However, due to its high flammability and potential health risks, it is important to exercise caution when using acetone. It is recommended to wear chemical-resistant gloves and protective clothing when handling acetone or acetone-based products.
While acetone is a potent solvent, it is not suitable for every application. For example, when mixed with ATF (Automatic Transmission Fluid), the two liquids do not combine effectively. Acetone has a high vaporization rate and evaporates quickly, leaving only the ATF behind. This mixture is not recommended for use as a penetrating oil due to its ineffectiveness and potential safety concerns.
In summary, acetone is a versatile chemical that can facilitate skin penetration by other compounds. While it is commonly used in nail polish removers and cosmetic procedures, it is important to use acetone in moderation and take the necessary precautions to avoid potential health risks.

Acetone is a mild paint remover
Acetone is a chemical that has been used for many years to thin and remove paint. It is often the main component in nail polish remover. It is a popular choice for paint thinning due to its tremendous thinning power, despite being a mild solvent. It is relatively safe for workers, with a low risk of regulation.
Acetone is a good option for those who want to strip paint from metal surfaces, such as carpentry tools. It is also useful for removing vinyl prints. However, acetone should be used with caution, as it has strong stripping capabilities and can damage delicate surfaces. It is also important to note that acetone is highly flammable and can cause eye and lung irritation, dizziness, and drowsiness.
When using acetone to remove paint, it is recommended to dampen a towel with the chemical and then wipe off the paint. It is unlikely to remove 100% of the paint, especially if it has been applied deeply in multiple layers. The effectiveness of acetone also depends on the type of paint and the surface being treated.
Acetone is sometimes combined with other chemicals to create paint removers or strippers. These products can come in thin liquid or semi-paste forms, with the latter being ideal for vertical or overhead applications. Biochemical and non-toxic strippers are milder and take longer to work, but they are safer for the user and can still remove multiple layers of paint.
In summary, acetone is a mild paint remover that can be effective for certain applications, but it should be used with caution due to its potential health and safety risks. It is important to consider the surface being treated and the desired level of paint removal before choosing a paint remover.

Acetone is flammable
Acetone is a highly flammable liquid that can ignite at room temperature. Vapours released by acetone can form an explosive mixture with air and can be ignited by a static discharge. Even dilute solutions of acetone in water may be flammable. Closed containers of acetone can rupture violently when heated, releasing their contents.
Acetone is a common ingredient in nail polish remover, comprising about 40% of the solution. It is also used extensively as a solvent for the safe transportation and storage of acetylene. Acetone is an organic compound with the formula (CH3)2CO and is colourless with a characteristic pungent odour.
When considering mixing acetone with ATF (Automatic Transmission Fluid), it is important to note that the two substances do not readily mix. The acetone, being less dense, will sit on top of the ATF and the mixture will separate over time. Acetone has a high vaporization rate and evaporates quickly, which can lead to the liquid flashing out and leaving only the ATF behind.
In addition to being flammable, acetone is also a potent material that can dissolve certain types of plastics and damage car systems by melting gaskets, o-rings, and other rubber parts. It is important to exercise caution when handling acetone and to wear chemical-resistant gloves to protect the skin.
