Polyglyceryl-3 stearate

Polyglyceryl-3 Stearate (CAS 26855-43-6), also known by trade names Santone 3-1S, Paniplus 504, Poem TRS 100, and Polyaldo TGMS, is a polyglycerol ester of stearic acid. It carries no assigned E-code and is classified as a non-ionic surfactant with an HLB value suited to water-in-oil emulsion systems.

In food manufacturing, it stabilises fat-based emulsions in margarine and bakery shortenings by reducing interfacial tension between lipid and aqueous phases. In personal care formulations, it functions as a co-emulsifier in creams and lotions, improving texture consistency and contributing to moisture retention at the skin surface.

Polyglyceryl-3 Stearate is available in food-grade and cosmetic-grade specifications and is compliant with REACH registration requirements for the European market. Suppliers typically offer it in drum and IBC packaging. Procurement teams should confirm grade suitability against FCC or relevant EU cosmetics regulation standards prior to sourcing.
