Summary

Cleansing Foaming Surfactant

Science

Mechanism of Action

As a 'crypto-anionic' surfactant, Sodium Laureth-11 Carboxylate reduces the surface tension of liquids, facilitating the mixing of oil and water. This action allows it to effectively lift and remove dirt, excess sebum, and other fat-soluble particles from the skin and hair, providing a thorough yet mild cleansing experience.
