What is Cetyl Alcohol?

Cetyl alcohol is a single-component fatty alcohol (C16) derived from coconut, palm or other vegetable oils. Like cetearyl alcohol, it is a waxy solid used to thicken creams, stabilise emulsions and provide a soft, conditioning skin feel. Despite the word 'alcohol' in its name, cetyl alcohol does not dry out the skin — it is the opposite of drying alcohols like ethanol or denatured alcohol.

Comedogenic Rating: What 2/5 Means for Your Skin

Cetyl alcohol is rated 2/5 comedogenic. For most people it is non-problematic, but a minority of acne-prone users do notice congestion when it appears high in the ingredient list of a leave-on product.

Benefits for skin
