  • Applications

    2-Hexyldecyl isononanoate (CAS 93843-29-9) is an ester of isononanoic acid with the 2-hexyldecyl alcohol. In cosmetics and personal care, it is commonly used as an emollient and solvent to improve skin feel and dissolve active ingredients. In perfumery, it serves as a solvent carrier for fragrance oils and helps disperse aroma compounds for stability. In polymers and plastics, this ester can function as a plasticizer or processing aid to enhance polymer workability. In coatings and inks, it is used as a solvent and rheology modifier to improve flow, leveling and gloss of formulations. In household and cleaning products, it is included as a base oil or conditioning component to provide slip and formulation stability.
