Optional CAS 52304-21-9 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Ammonium Myristyl Sulfate is an anionic surfactant known for its cleansing and foaming properties. It effectively emulsifies oils and dirt for easy rinsing from the skin.

Summary

surfactant cleansing foaming

Science

Mechanism of Action

This anionic surfactant reduces water's surface tension, allowing it to mix with and lift oil and dirt. Its molecular structure traps air bubbles, contributing to foam formation and efficient impurity removal.
