What Is PPG-14 Butyl Ether?
PPG-14 butyl ether is a synthetic mix of a polypropylene glycol derivative and non-irritating fatty alcohol known as butyl alcohol. The mix forms a new compound that functions as a solvent and skin-conditioning agent. This ingredient helps restore a supple feel to skin and enhances the texture of personal care product formulas. In addition to skin care, PPG-14 butyl ether is used in other types of self-care products such as perfumes and deodorants. As a raw material, PPG-14 butyl ether is described as a clear, almost colorless, slightly viscous liquid. The molecular weight of PPG butyl ether ingredients increases as the number they’re correlated with rises (hence PPG-14 butyl ether is lighter than, say, PPG-40 butyl ether). According to the Cosmetic Ingredient Review, PPG-14 butyl ether is typically used in amounts between 0.1% to 1%, although higher concentrations are permissible. Their most recent assessment (in 2017) concluded this ingredient is safe for use in cosmetics.
