  • Applications

    Octadecyl decanoate is primarily used as an emollient and conditioning agent in cosmetics and personal care, providing a smooth feel in moisturizers, lotions, and lip care oils; it serves as a carrier for active ingredients and fragrance components in perfumery and fragrance formulations; in polymers and plastics, it can function as a lubricant and softening additive to improve processing and gloss; in coatings and inks, it can act as a waxy additive to improve slip and pigment dispersion; in household products, it may be used as a surface conditioning agent or moisturizing additive in cleaners and detergents; use is subject to local regulations and formulation limits.
