  • Applications

    1-Linolenoylglycerol (18465-99-1) is a monoacylglycerol that functions as an emulsifier and surfactant across several industries. In food processing, it acts as an emulsifier and thickening aid in baked goods and spreads. In cosmetics and personal care, it serves as an emollient and surfactant in creams, cleansers, and lotions. In pharmaceutical formulations, it can act as a lipid-based excipient and solubilizer for lipophilic active ingredients. It is also used as a processing aid and potential plasticizer in edible films and biodegradable polymers. It can contribute as a co-surfactant in industrial cleaning formulations. In specialty lipid synthesis, it may be used as an intermediate for structured lipids.
