  • Applications

    25-Methyl-1-hexacosanol (CAS 75382-95-5) is a long-chain fatty alcohol commonly used as a waxy emollient and thickening agent in cosmetics and personal care formulations; it also serves as a lubricant and processing aid in polymer and plastics manufacture, helping improve slip and processing stability. As a wax-like additive, it is used in coatings, inks, and adhesive formulations to enhance slip, gloss, and water resistance. In household products such as polishes and cleaners, it functions as an emollient and thickener. In industrial manufacturing, it acts as a lubricant component in metalworking fluids. It can also be a raw material or intermediate for the synthesis of esters used in fragrance, cosmetics, or specialty chemical applications.
