Science
Mechanism of Action
This copolymer efficiently regulates product consistency by modulating viscosity, thereby enhancing texture and application. Its emollient action helps to soften and smooth the skin, while its film-forming capability assists in moisture retention and product adherence. Additionally, it likely functions as a humectant, drawing moisture into the stratum corneum, and an emulsion stabilizer, maintaining product integrity.

The Formula
Formulation
Stability
The compound is generally stable and does not readily hydrolyze or deteriorate when stored in the absence of oxygen. However, prolonged exposure to temperatures exceeding 50°C can induce oxidation and lead to the formation of peroxides. Integrating antioxidants into formulations is recommended to mitigate these radical mechanisms.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has deemed PEG/PPG-32/3 Copolymer safe for use in cosmetics under current conditions of intended use. It is associated with minimal to no ocular or dermal irritation and exhibits very low acute and chronic toxicities. While it does not readily penetrate intact skin, application on damaged skin should be avoided. Manufacturers are advised to minimize impurities such as ethylene oxide and 1,4-dioxane.
