MEA-LAURYL SULFATE.

Valuable CAS 4722-98-9 / CLEANSING, SURFACTANT - CLEANSING

MEA-Lauryl Sulfate is an anionic surfactant that efficiently lowers surface tension, enabling the harmonious mixing of oil and water-based ingredients. It serves as a multi-functional agent, contributing to cleansing, foaming, emulsifying, and thickening in various formulations. Primarily, it aids in dislodging fat and soil particles from the skin and hair, ensuring effective purification.

Summary

cleansing surfactant - cleansing foaming emulsifying thickening

Science

Mechanism of Action

This anionic surfactant operates by significantly reducing surface tension, which is crucial for blending immiscible substances like oils and water. Its dual hydrophilic and hydrophobic structure allows it to effectively encapsulate and remove fat and soil particles from the skin and hair, providing a thorough cleansing action.
