  • Applications

    Ethyl henicosanoate is commonly used in perfumery and fragrances as an odorant and fixative component, providing long-lasting notes in formulations. In cosmetics and personal care, it may act as an emollient and solvent for active ingredients and fragrances, improving texture and spreadability. It can serve as a non-polar solvent or carrier in household and cleaning products. In industrial manufacturing and coatings, it is employed as a plasticizer and processing aid for polymer systems and as a solvent for formulation concentrates. It may also function as an intermediate in chemical synthesis for longer-chain esters.
