  • Applications

    1-Palmitoyl-2-oleoyl-3-stearoylglycerol (CAS 2190-27-4) is a triglyceride composed of palmitic, oleic, and stearic acids, serving as a lipid base and emollient in cosmetics and personal care (providing skin conditioning and acting as a carrier for actives and fragrances); it appears as a component of fat systems in food processing, contributing to texture, mouthfeel, and melting behavior; it can function as a lipid-based excipient or carrier in pharmaceutical formulations and nutraceuticals; in polymer and plastics processing it can act as a processing aid, lubricant, or plasticizer to improve flow and reduce friction; and in coatings, inks, and household products it serves as a natural oil-based carrier for cleaning formulations and other oil-containing products.
