Science

Mechanism of Action

This ingredient operates on multiple fronts: as a tocopherol derivative, it provides antioxidant defense by neutralizing free radicals, safeguarding skin cells from oxidative stress. Its polyoxypropylene (PPG) ether structure allows it to function as a solubilizer and solvent, while also attracting moisture to the skin as a humectant. It forms a protective, conditioning layer, contributing to skin cleanliness and suppleness.

The CIR Expert Panel concludes that PPG-20 TOCOPHERETH-5 is safe for cosmetic use when precisely formulated to be non-irritating. However, similar alkyl PEG/PPG ethers may carry a risk of contamination by ethylene oxide and 1,4-dioxane, both recognized carcinogens; this risk is effectively eliminated through proper manufacturing filtration. As a derivative of Tocopherol, its components are generally recognized as safe (GRAS) food ingredients by the FDA.
