  • Applications

    1-Decanol, 2-methyl- is a long-chain aliphatic alcohol (C11) that is mainly used as an intermediate and processing aid in several industries. In perfumery and cosmetics, it serves as a fragrance raw material and as a precursor to ester derivatives for flavor and scent formulations, and can act as an emollient in personal care products. In coatings and inks, it functions as a solvent and processing aid to improve flow and compatibility. In polymers and plastics, it is used as a chemical intermediate for synthesis of plasticizers and as a building block for ester derivatives in polyester or polyurethane systems. In household cleaning formulations, it may serve as a solvent or co-solvent for active ingredients. Its use is subject to local regulations and formulation limits.
