  • Applications

    Octadecanoic acid, 12-hydroxy-, 2-octyldodecyl ester (CAS 74659-70-4) is a long-chain hydroxy fatty acid ester used as a wax-like lubricant and rheology modifier in a range of formulations. In cosmetics and personal care, it acts as an emollient, thickener, and texture enhancer in creams, lotions, and hair/skin care products; in polymers and plastics, it serves as a processing aid and plasticizer to improve flexibility and processability; in coatings and inks, it functions as a waxy additive that helps adjust viscosity and surface feel; in industrial manufacturing, it is used as an intermediate for specialty esters and as a component of lubricant formulations; and in household products, it may be employed as an emollient or texture-enhancing additive to improve slip and sensory attributes.
