Alcohol in cosmetics: What does 'Alcohol' on the label mean?
Arin Editorial · how this is made
When you see 'Alcohol' on a cosmetic label, it is the same substance you drink: ethanol. However, the version used in cosmetics is usually denatured, meaning it has been made undrinkable. That is why it may also appear as 'Alcohol Denat.' or 'Ethyl Alcohol' on the label.
What is this ingredient?
Ethanol is the alcohol found in alcoholic beverages. In cosmetics, it is 'denatured' to prevent it from being consumed: a bitter taste is added to make it undrinkable. In the US, this process follows government-set formulas. This way, the same substance can be safely used in cosmetics. It appears in many products like perfumes, lotions, hair care, and makeup.
What does it do in cosmetics?
Alcohol has multiple functions. It is a solvent, helping other ingredients mix. It is antimicrobial, preventing the growth of bacteria. It is also an astringent, meaning it tightens the skin. It is used as an antifoaming agent, a viscosity controller, and a carrier for fragrance. It has no single purpose; it is a versatile helper in formulations.
Safety and controversies
Alcohol is classified by IARC as Group 1: there is sufficient evidence that it causes cancer in humans. However, this is a hazard classification, not a risk assessment. It means 'this substance can cause cancer under certain conditions'; it does not mean 'it causes cancer at cosmetic use levels.' Skin and eye irritation studies give mixed results: some found no irritation, others reported mild or severe irritation. These results usually come from tests with high concentrations; the amounts used in cosmetics are much lower. It may cause dryness or a stinging sensation in people with sensitive skin.
Current regulatory status: Alcohol is not a prohibited or restricted ingredient in cosmetics; its safety is assessed under the EU Cosmetics Regulation and it is used accordingly.
If you see 'Alcohol', 'Alcohol Denat.', or 'Ethanol' on the label, do not panic. The IARC classification does not mean you need to avoid cosmetic products. However, if your skin is dry or sensitive and the product stings or feels drying, you might try an alcohol-free alternative.
