Formula IngredientEmollientCetyl Alcohol
INCI: Cetyl Alcohol
Cetyl alcohol is a fatty alcohol (hexadecan-1-ol, C16H34O) derived from coconut oil, palm kernel oil, or petroleum. Despite its name, it behaves nothing like drying alcohols such as ethanol — it is a waxy solid that acts as an emollient, emulsifier, and thickener, helping to create smooth, stable cream and lotion textures. It softens and conditions the skin by forming a protective film on the surface that reduces moisture loss.

Is Cetyl Alcohol safe? Key considerations
Can Cetyl Alcohol cause irritation?
Low RiskThe CIR Expert Panel has classified cetyl alcohol as non-sensitizing, non-toxic, and safe for cosmetic use. INCIDecoder rates its irritancy at 2/10 (low). However, some individuals with rosacea, psoriasis, or a known contact allergy to fatty alcohols may react — fatty alcohols can alter the lipid bilayer of the epidermis in susceptible skin. No EU CosIng Annex II or III restrictions apply.
Does Cetyl Alcohol increase sun sensitivity?
No RiskCetyl alcohol does not increase photosensitivity. No sun protection precautions are needed based on its presence in a formulation.
Is Cetyl Alcohol safe during pregnancy?
SafeCetyl alcohol is not flagged in any reproductive toxicology database. The CIR Expert Panel considers it non-toxic. The FDA lists it as a permitted food additive. It is widely regarded as safe during pregnancy at standard cosmetic concentrations.
