Surfactant Emulsifying Cleansing Light Stabilizer Dispersing Agent Solubilizing Agent

Science

Mechanism of Action

This ingredient acts primarily as a surfactant, reducing surface tension to facilitate the removal of impurities and promoting better spreadability of formulations. Its emulsifying properties are key in forming and stabilizing oil-in-water mixtures, ensuring product consistency. Furthermore, it serves as a solubilizer for active ingredients, fragrances, and colorants, and functions as a light stabilizer to protect light-sensitive compounds from degradation. As a polyethylene glycol (PEG) derivative, it contributes to hydration by attracting and retaining moisture within the skin.
