ALCOHOL (Ethanol) – function in cosmetics

Ethyl alcohol, used as a solvent and to give a quick-drying feel.

What it is

In INCI, alcohol means ethanol. It dissolves fragrance and other ingredients, evaporates quickly, gives a light, fresh feel and helps preservation at higher levels. Alcohol denat. is ethanol made unfit for drinking.

Where it is used

Found in perfumes, deodorants, toners, gels, hair sprays and hand sanitisers.

Limits of interpretation

The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.

High in the list it is a main solvent; low in the list it may only carry fragrance or extracts. Its effect on skin depends on concentration and the rest of the formula.
