Acetone is a solvent. It is not an allergen as some think. The human body produces small amounts of acetone through metabolism. It is however an irritant which means it can dry skin faster than natural moisture can be produced. This can cause some symptoms that are often misdiagnosed as an allergy.
Efficient Removal of UV Gel and Nail Coatings
Acetone is a crucial product in the nail industry as it is the most efficient remover for both UV gel products and liquid and powder nail coatings. It quickly breaks the bonds without melting them, altering the structure so it can be easily removed from the nails.
A way to understand how this works is to imagine a roll of kitchen paper towel is put in a bucket of water. It will become mushy and lose its structure, but it is still paper though. If it is dried out the structure will be different, in that it is no longer in neat sheets, but it is still paper in a chaotic state.
Acetone’s Role in Nail Product Removal
Even though it can be drying for the skin, it remains the most efficient option because the contact time with the skin is kept as short as possible.
There are many ‘acetone free’ polish removers where acetone is replaced by ethyl acetate or butyl acetate. These will remove polish but are not so efficient so takes longer to do the job. This results in longer skin contact with an equally drying solvent.
My advice to consumers is to use acetone to remove polish as it is quicker and skin contact is as short as it can be. The alternatives need more rubbing and longer skin contact.
Why Cosmetic-Grade is Essential for Nail Care
But only buy acetone suitable for cosmetic use. The acetone sold in stores such as DIY is unlikely to be impure and may have trace ingredients that are unsuitable for skin contact and could even be an allergen. Pure acetone from beauty suppliers is best for use in nail services.
Don’t be scared of acetone, other than understanding the fact that it is very flammable and any flame near to it can cause a flashback. Acetone should be stored in the cool and dark as it is very volatile meaning it evaporates easily so keep all containers of acetone covered to stop evaporation as it does have a strong smell that many don’t like or believe to be harmful.
It is the most efficient for nail coating removal and is often an ingredient in cleansers. It is not so effective alone for cleansing and dehydrating the nail plate. A mix of a solvent and alcohol (such as isopropyl alcohol, IPA) is the most efficient for this job.
Acetone Science Check
Acetone does not damage, weaken, or change the structure of the natural nail plate.
It does not denature keratin or cause permanent harm.
Acetone temporarily removes surface oils and moisture, which can make nails feel dry. This is a cosmetic effect, not structural damage, and is fully reversible with proper hydration and regular use of nail oil.
