16-Methylheptadecan-1-ol (Isostearyl alcohol) is a branched-chain fatty alcohol widely used as an emollient, viscosity modifier, and conditioning agent in cosmetics and personal care formulations. It is also used as an intermediate for producing esters, surfactants, lubricants, plasticizers, and specialty chemical additives due to its excellent spreading properties, low freezing point, and oxidation stability.
