  • Applications

    1-Heptacosanol (CAS 2004-39-9) is used as an emollient and thickener in cosmetics and personal care, contributing to conditioning, moisturization, and product texture; it also serves as a wax-like processing aid and slip modifier in polymers/plastics to influence crystallinity, rheology, and end-use feel; as a wax additive in coatings and inks to improve gloss and moisture resistance; as a precursor for fatty alcohol-derived nonionic surfactants (for example fatty alcohol ethoxylates) used in cleaning formulations; and can function as a waxy component in various household products such as polishes and surface cleaners.
