OLEYL BETAINE

Safety grade: A

Oleyl Betaine is a gentle, plant-derived cleaning agent derived from oleic acid (found in oils) and a natural compound called betaine. It works like a mild soap that helps remove dirt and oil while being kind to skin and hair.

This ingredient cleanses the skin and hair, reduces frizz and static electricity, boosts lather in shampoos and cleansers, and conditions both hair and skin by helping them retain moisture.
