Polyglyceryl-3 Dicitrate/Stearate
What is Polyglyceryl-3 Dicitrate/Stearate?
Polyglyceryl-3 Dicitrate/Stearate is a multi-functional ingredient created by esterifying polyglycerol-3 with citric acid and stearic acid. Polyglycerol-3 forms through the polymerization of glycerol, a simple polyol abundant in nature from plant and animal sources. Citric acid derives from citrus fruits, while stearic acid comes from vegetable or animal fats. This compound belongs to the polyglyceryl ester family, commonly employed in rinse-off and leave-on cosmetic products like creams, lotions, and cleansers. It acts primarily as an emulsifying agent and surfactant, lowering surface tension between immiscible oil and water phases to form stable emulsions. This ensures uniform texture, prevents separation, and enhances product spreadability, contributing to effective delivery of active ingredients in formulations.
Benefits
Helps create stable emulsions for smooth, consistent product texture
Supports gentle cleansing as a mild surfactant
Offers a PEG-free option in formulations for broader compatibility
