Valuable CAS 68951-67-7 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A high-performance non-ionic emulsifier and surfactant characterized by its 12-mole ethoxylation, which grants it superior water solubility. It is primarily used to stabilize complex formulations and refine the sensory profile of high-end skincare products.

Surfactant Cleansing Agent Emulsifying Agent

Science

It acts as a surface-tension modulator that bridges the gap between aqueous and lipid phases to create uniform emulsions. In precision skincare, it is frequently utilized to disperse silicone polymers, facilitating a silky, non-greasy finish and enhancing the skin's capacity for sebum regulation.
