Science
Mechanism of Action
This ingredient functions as an emulsifier by reducing interfacial tension between immiscible liquids, due to its dual lipophilic and hydrophilic nature. Derived from glycerin, it is expected to provide humectant properties, attracting moisture and supporting skin barrier integrity.

Stability
Optimal stability occurs at pH 4.0-5.5 (preferably 4.5-5.0) with dilute acid, or above pH 10 (preferably 11.0-12.0) with dilute base. pH adjustment also helps mitigate oxidative degradation at elevated temperatures.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel deemed glycerin, its parent compound, safe as used, up to 78.5% in leave-on products. FDA considers glycerin GRAS, though advises against Jatropha species as a source due to potential toxins.
