Ingredient review
Phenethyl Alcohol
INCI: PHENETHYL ALCOHOL
A gentle, rose-scented alcohol that adds fragrance and helps preserve formulas without the drying effects of denatured alcohol.
In plain English
Phenethyl alcohol is a natural compound found in rose, jasmine, and other flowers. In skincare, it's used to give products a pleasant floral scent and to help keep them fresh by boosting the preservative system. Unlike denatured alcohol, it doesn't strip moisture from your skin, so it's generally well-tolerated even by sensitive types.
