  • Applications

    Hydroxyoctacosanyl Hydroxystearate (CAS 93840-71-2) is a high‑molecular‑weight wax ester used in cosmetics/personal care as an emollient and slip agent, helping condition the skin and provide desirable texture in creams, lotions, and solid balms; it also serves as a rheology modifier and structuring agent in cosmetic formulations. In polymers and plastics, it can function as a long‑chain plasticizer or processing aid to improve lubrication and flexibility during extrusion or molding. In coatings and inks, it acts as a wax additive to enhance gloss, slip, and open time, while in household products it can contribute fatty‑oil‑like conditioning properties to cleaners and polishes. Its use is formulation‑dependent and subject to local regulations and limits.
