Description

1,3-Diolein is a high-purity, unsaturated diglyceride, a key chemical intermediate and functional ingredient. This compound matters for its role as a versatile building block in organic synthesis and as a non-ionic surfactant or emulsifier in advanced formulations. Industries such as pharmaceuticals, cosmetics, and specialty chemicals need it for research, development, and production of lipid-based delivery systems and fine chemicals.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, phospholipids, and other bioactive lipid conjugates for drug delivery applications.
• Cosmetic & Personal Care Ingredient: Acts as an emollient, skin-conditioning agent, and co-emulsifier in creams, lotions, and serums.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies, particularly those involving lipases and lipid metabolism.
• Food-Grade Emulsifier: Employed as a food additive (where compliant) to stabilize emulsions in certain food products.
• Lubricant & Plasticizer: Functions as a bio-based lubricant additive or a plasticizer in specialized polymer formulations.
• Surfactant Synthesis: A crucial precursor for manufacturing non-ionic surfactants and other oleochemical derivatives.
