Used as a non-ionic surfactant and solubilizing agent in cosmetic and pharmaceutical formulations. Its polyether chain provides excellent water solubility and emulsifying properties, making it effective in stabilizing oil-in-water emulsions. Commonly found in skin cleansers, moisturizers, and topical delivery systems where it enhances penetration of active ingredients. Also utilized in industrial cleaning products for its ability to reduce surface tension and improve wetting. Low irritation potential makes it suitable for sensitive skin formulations.
