  • Applications

    Octyldodecyl isostearate (CAS 93803-87-3) is a lightweight, skin-friendly ester widely used in cosmetics and personal care as an emollient and slip agent to improve spreadability and conditioning in lotions, creams, and lip products. It also serves as a solvent and carrier for fragrance oils and active ingredients, aiding fragrance delivery and formulation stability. In perfumery and cosmetics, it can function as a fragrance carrier and processing aid for smoother application in color cosmetics and coatings. In industrial contexts, it is evaluated as a lubricating additive or plasticizer for certain polymers and coatings. It may also be found in household products as an emollient and fragrance carrier, depending on regulatory and formulation limits.
