  • Applications

    Octadecyl lactate is the long-chain ester of lactic acid with an 18-carbon alcohol, used primarily as an emollient and softening agent in cosmetics and personal care products (creams, lotions, lip products). In polymers and coatings, it can act as a plasticizer or slip agent to improve processing and the feel of finishes and inks. In industrial manufacturing, it serves as a low-volatility solvent or carrier for lipophilic actives and as a lubricating additive in plastic and coating formulations. It can also function as an intermediate in the synthesis of other esters or specialty chemicals, depending on formulation and local regulations.
