  • Applications

    Isodecyl Stearate (CAS 31565-38-5) is primarily used as an emollient and slip agent in cosmetics and personal care, providing a soft feel and easy glide in products such as creams, lotions, and facial oils; it also commonly serves as a solvent or carrier for fragrance oils and fragrance components in perfumery and fragrance applications. In household products, it is used as a conditioning additive to improve texture, slip, and spreadability in cleaners and surface-care formulations. In industrial manufacturing, Isodecyl Stearate can function as a processing aid, a plasticizer, and a light lubricant for plastics and polymers; in coatings and inks, it can act as a softening agent for the film and a flow modifier to improve film formation. It is also considered as a plasticizer or compatibility agent in adhesives to enhance flexibility and surface gloss. Its use is typically formulation-dependent and subject to local regulations and limits.
