About

A long-chain branched fatty alcohol — serves as a skin-conditioning emollient that gives products a rich, luxurious feel without greasiness.

Hexyldecyloctadecanol is a C16 + C18 branched long-chain fatty alcohol. It is produced by the reduction of corresponding fatty acids derived from natural oils. In cosmetics it functions as a thickener, opacifying agent, and emollient. Its branched structure gives it a lower melting point than straight-chain analogues, resulting in a pleasant sensory profile. It is not listed in EU Annex II (banned) or Annex III (restricted) and is considered safe at concentrations used in leave-on and rinse-off products.
