Science
Mechanism of Action
This ingredient acts as an emulsifier and surfactant by reducing interfacial tension, facilitating the smooth integration and stability of immiscible phases in formulations. It also attracts and retains moisture, functioning as a humectant to boost skin hydration. Furthermore, it aids in dissolving other components, acts as a solvent to improve formula texture, supports the delivery of other ingredients, and contributes to skin conditioning and gentle cleansing.

Safety Profile
The CIR Expert Panel has concluded PEG-75 Propylene Glycol Stearate is safe for use in cosmetic products at concentrations not exceeding 10%. The previous recommendation against its use on damaged skin has been removed. Manufacturers are advised to implement purification steps to control potential impurities such as 1,4-dioxane, ethylene oxide, polycyclic aromatic compounds, and heavy metals.
