Science
Mechanism of Action
This ingredient functions distinctly within formulations and on the skin. Its tocopherol (Vitamin E) component acts as a potent fat-soluble antioxidant, inhibiting oxygen-promoted reactions to prevent ingredient deterioration and protecting skin cells from free radical damage, including some photoprotection against UVB radiation. As a polypropylene glycol and tocophereth derivative, it reduces liquid surface tension, thereby solubilizing and finely mixing immiscible substances like oil and water, crucial for emulsion stability. It also functions as a skin conditioning agent, contributing to improved skin feel.

Safety Profile
The CIR Expert Panel determined that polypropylene glycols (PPGs) with 3 or more repeating units, including PPG-10, are safe for use in cosmetic formulations, provided they are formulated to be non-irritating. The tocopherol component is generally recognized as safe (GRAS) for food use, and topical cosmetic exposure is not expected to exceed safe systemic levels.
