About
A branched ester (hexyl alcohol + isostearic acid) used as a light, silky emollient. Reliable workhorse in makeup and lotions.
Hexyl isostearate (CAS 94247-25-3) is the hexyl alcohol ester of isostearic acid. The branched fatty acid gives a light, dry skin feel with low oxidative tendency compared to straight-chain analogs. It functions as a non-ionic emollient and pigment-wetting agent in foundations, lipsticks, sunscreens, and lightweight lotions. CIR has reviewed alkyl isostearate esters as safe for cosmetic use. No CMR, endocrine, or significant GHS hazards; low irritation and sensitization potential.
