  • Applications

    1-Monolinolein (CAS 2277-28-3) is a monoacylglycerol derived from linoleic acid, commonly used as an emulsifier and texturizing agent in foods to stabilize fats and improve mouthfeel; in cosmetics and personal care it acts as an emulsifier, an emollient, and a surfactant, contributing to formulation stability and skin feel; in pharmaceuticals it can serve as an excipient and lipid carrier or solubilizer in certain dosage forms; in the plastics and polymers sector it may function as a plasticizer or processing aid to improve flexibility; in household cleaning formulations and coatings/inks it can serve as an emulsifier and stabilizer to aid oil dispersion. Applications are subject to local regulations and formulation limits.
