  • Applications

    Decyl stearate (CAS number: 32509-55-0) is commonly used as an emollient and slip agent in cosmetics and personal care products, providing a light, non-greasy feel. In perfumery and fragrance formulations it serves as a solvent/vehicle for aroma components. It can function as a processing aid, plasticizer, or lubricant in coatings, inks, and plastics formulations to improve handling and texture. It is also employed in household and cleaning products as a conditioning additive to enhance pleasantness and skin compatibility.
