Science
Mechanism of Action
This copolymer operates by forming a continuous, flexible film across the skin's surface, which physically limits water evaporation. As a PEG/PPG derivative, its hydrophilic nature allows it to attract and bind water molecules, enhancing moisture retention and contributing to the skin's hydration levels. Furthermore, it aids in product formulation by improving spreadability, acting as a solvent and solubilizer, and providing conditioning benefits.

Safety Profile
While a specific CIR safety assessment for PEG-9/PPG-7/MDI COPOLYMER is not available, the broader class of polyethylene glycols (PEGs) and polypropylene glycols (PPGs) and their derivatives are widely utilized in cosmetic formulations and generally considered to exhibit very good skin tolerance. The CIR Expert Panel has determined PEG propylene glycol derivatives as safe for cosmetic use. INCI Beauty indicates 'No penalty' across all categories for this ingredient, suggesting a low level of concern based on existing data.
