Science

Mechanism of Action

This nonionic block linear copolymer is structured with hydrophilic polyethylene oxide (PEO) blocks surrounding a hydrophobic polypropylene oxide (PPO) core. This specific architecture provides the molecule with surface-active properties, enabling it to function effectively as a surfactant, emulsifying agent, solubilizing agent, and dispersing agent within formulations. In skincare, it contributes to skin conditioning properties, leading to an improved tactile experience on cleansed skin.
