Solvent Surfactant Emulsifier Cleansing Agent Humectant Skin Conditioner Rheology Modifier

Science

Mechanism of Action

This amphiphilic polymer, a fusion of polyethylene glycol (PEG) and polypropylene glycol (PPG), functions by improving a formulation's hydrophilicity. Its PEG component is instrumental in forming hydrated layers, contributing to skin conditioning and product texture. The copolymer acts mechanistically as a solvent, surfactant, emulsifier, cleansing agent, and humectant, thereby enhancing overall product performance.
