  • Applications

    2-Octyldodecyl 2-ethylhexanoate (CAS 69275-04-3) is a fatty ester widely used as an emollient and solvent in cosmetics and personal care, providing slip and a light, non-greasy feel. It is commonly employed as an emollient and solvent for fragrance components in perfumery, helping dissolve and carry fragrance oils. In coatings, plastics, and related applications, it can act as a plasticizer or processing aid to improve flexibility and handling of polymer formulations. In household cleaning products, it serves as a solvent/emollient alternative to more volatile solvents, contributing to formulation rheology and skin feel. It may also be used as a solvent or carrier in pharmaceutical formulations, depending on local regulations and formulation limits.
