AMMONIUM LAURYL SULFOSUCCINATE.

Valuable CAS 221391-03-3 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

A gentle anionic surfactant that effectively removes oils, dirt, and sebum while maintaining skin barrier integrity. Its larger molecular structure compared to traditional sulfates reduces skin penetration, making it suitable for sensitive skin cleansing applications.

Science

Functions by reducing water's surface tension through its amphiphilic molecular structure, enabling efficient spread and penetration. Forms micelles that encapsulate and suspend oils, dirt, and sebum for easy removal during rinsing, while its larger molecular size limits barrier penetration compared to simpler sulfates.
