  • Applications

    1-Monopalmitin (CAS 542-44-9) is a monoacylglyceride used primarily as an emulsifier and surfactant in foods (often as an ingredient in oil–water emulsions and texture modifiers). In cosmetics and personal care, it acts as an emollient, emulsifier, and stabilizer for emulsions in creams and lotions. It is also employed in household cleaning products as a surfactant to aid cleaning and foaming. In industrial manufacturing, it serves as a processing aid and as a lubricant or plasticizer in polymer formulations, and as a dispersing agent in coatings and inks.
