About
A branched ester of oleic acid and hexyldecanol — a silky, lightweight emollient. Well-tolerated and widely used in luxury skincare and sun care.
Hexyldecyl oleate (CAS 94278-07-6) is the ester formed between oleic acid and 2-hexyldecanol, a branched fatty alcohol. It functions as a skin conditioning emollient with high spreadability, low viscosity, and a silky, non-greasy finish, making it popular in luxury creams, sunscreen emulsions, and makeup. EU CosIng lists it as emollient/skin conditioning. CIR has reviewed closely related branched oleate esters and concluded they are safe as used. No CMR, endocrine, or genotox flags. Score is mid Good tier — clean profile supported by read-across and decades of emollient-ester industry use.
