Glyceryl stearate citrate

Glyceryl Stearate Citrate (CAS 55840-13-6) is an esterified monoglyceride produced by combining glyceryl stearate with citric acid. It is sold under trade names including Acidan, Axol LC, Poem K-30, Acidan N 12, and Sunsoft 621B. No E-number designation applies to this ingredient.

In food manufacturing, Glyceryl Stearate Citrate functions as an emulsifier in fat-based systems such as margarines and shortenings, where the citrate group enhances oil-water interfacial stability and contributes mild acidulant activity. In personal care formulations, it stabilises oil-in-water emulsions in creams and lotions by reducing interfacial tension between the aqueous and lipid phases.

Glyceryl Stearate Citrate is available in food-grade and cosmetic-grade specifications and is subject to REACH registration requirements for EU supply. Suppliers typically offer the material in flake or pellet form, packed in fibre drums or lined bags. Buyers should confirm grade suitability against relevant FCC or regional cosmetic regulatory frameworks.
