Summary

Surfactant Cleansing Emulsifier Emulsion Stabilizer Dispersant

Science

Mechanism of Action

This ingredient reduces the surface tension of liquids, enabling water to effectively blend with oils and dirt for easier rinsing. Its molecular structure features both a lipophilic (fat-attracting) portion and a hydrophilic (water-attracting) ethoxy chain, allowing it to act as a surface-active agent and emulsifier at the interface between oil and water.
