Safety Profile
While PPG-77 Trimethylolpropane Ether has not undergone specific review by the Cosmetic Ingredient Review (CIR) Expert Panel, evaluations of related polypropylene glycol (PPG) ethers provide context. PPG Butyl Ethers, for instance, were deemed safe for use in cosmetics when formulated to prevent irritation. PPG Stearyl Ethers were found safe at concentrations between 2% and 10%, and not exceeding 25%. Additionally, PPG-2 and PPG-3 Methyl Ether were concluded safe for cosmetic use at 0.4% to 2%. The broader class of polypropylene glycols and their derivatives is generally recognized for exhibiting very good skin tolerance.
