  • Applications

    Dotriacontanol (CAS 79554-32-8) is a very long-chain fatty alcohol (C32) that is typically used as a waxy additive in cosmetics and personal care, functioning as a thickener, emollient and texture enhancer; it is also incorporated into coatings and polishes as a wax component to impart gloss, slip and water resistance; in household products and cleaners it serves as a wax-like thickener and glossing agent; in plastics, rubbers and other polymer formulations it can act as a processing aid and lubricant to improve processing and surface feel; and it may serve as an intermediate for the synthesis of long-chain esters used in specialty fragrances, coatings and cosmetic ingredients.
