Science
Mechanism of Action
This ingredient functions by creating a delicate emollient film on the skin, contributing to a smoother and softer texture. In formulations, its emulsifying properties are crucial for forming stable, finely dispersed mixtures of oil and water, thereby preventing phase separation. As a surfactant, it effectively lowers surface tension, aiding in the dispersion of oil and dirt, which facilitates their removal during cleansing.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed PEGylated alkyl glycerides, including Glyceryl Hydrogenated Soyate (a related compound), concluding their safety under current use practices and concentrations, provided they are formulated to be non-irritating. A maximum concentration of 10% is recommended for leave-on products, a restriction based on ocular and sensitization data from similar PEG glyceryl cocoates. Potential for 1,4-dioxane contamination exists due to the ethoxylation process, which can be controlled through rigorous purification. The SCCS has not specifically reviewed PEG-7 GLYCERYL SOYATE, and while the FDA does not approve cosmetic ingredients, no specific warnings have been identified.
