  • Applications

    Cetylarachidol, CAS 17658-63-8, is a long-chain fatty alcohol used primarily in cosmetics and personal care as a waxy structuring agent and thickener for creams, lotions, and emulsions, while also serving as an emollient and conditioning component for skin and hair. It is also evaluated for use in household products such as thickeners and rheology modifiers in cleaners and detergents. In the polymer/plastics industry it can function as a lubricating additive and processing aid to improve handling and surface feel. In coatings and inks it can act as a wax-like additive to enhance gloss, slip, and water resistance.
