Valuable CAS 68815-25-8 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

TEA-C12-15 Alkyl Sulfate functions primarily as a cleansing and foaming agent, effectively reducing surface tension to aid in the removal of impurities from the skin. Its use is deemed safe with specific formulation restrictions to prevent irritation and the formation of harmful byproducts.

Summary

Cleansing agent Foaming agent Surfactant

Science

Mechanism of Action

This ingredient acts as a surfactant, significantly lowering the surface tension between water and oil phases. This action enables more efficient emulsification and dispersion of dirt and sebum, facilitating their removal from the skin's surface during cleansing.
