Summary

skin conditioning hair conditioning surfactant cleansing

Science

Mechanism of Action

The hydrophobic isostearoyl chain anchors the ingredient to the skin's surface and lipids, while hydrolyzed corn protein peptides bond with keratin. This creates a protective, semi-permeable barrier that maintains moisture and reduces surfactant-induced irritation.
