Isostearyl Sebacate
What is Isostearyl Sebacate?
Isostearyl Sebacate is a diester compound created by reacting isostearyl alcohol, a long-chain branched alcohol, with sebacic acid, a naturally occurring dicarboxylic acid typically sourced from castor oil. Classified as an emollient in cosmetic formulations, it primarily serves in moisturizers, creams, and lotions. In products, it functions by forming an occlusive layer on the skin surface, which minimizes water evaporation and delivers a silky, non-greasy texture. This action supports skin barrier integrity, improves product glide during application, and allows for better incorporation of active ingredients. Its stable, inert nature suits a range of skin types, contributing to overall formulation elegance and sensory appeal without residue.
