Science
Mechanism of Action
On the skin, PEG-30 Glyceryl Triisostearate acts as a mild surfactant, efficiently capturing oil-soluble debris and makeup for effortless rinsing without leaving a greasy film. Its emulsifying properties are crucial for product stability and texture. Furthermore, it can enhance skin hydration by forming hydrogen bonds with water molecules, thereby supporting the skin's barrier function and reducing moisture loss.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed PEG-20 Glyceryl Triisostearate, a structurally similar compound, as safe for cosmetic use. General safety data on some PEG compounds indicates no concern at concentrations up to 100%. However, a potential concern for PEG compounds includes contamination with toxic impurities such as Ethylene Oxide and 1,4-Dioxane. The maximum use concentrations cited (20% for rinse-off, 5% for leave-on) are specifically for PEG-20 Glyceryl Triisostearate, suggesting a cautious approach for leave-on applications of related PEGs like PEG-30 Glyceryl Triisostearate.
