Cocamidopropyl Betaine – Mild Surfactant

Description

Cocamidopropyl Betaine

Cocamidopropyl Betaine is a mild, coconut-derived amphoteric surfactant used in cosmetic and personal care formulations. It functions as a secondary cleanser and foam booster, enhancing lather quality while reducing the irritation potential of primary surfactants.

This grade contains approximately 30% surfactant matter (active matter) and is compatible with anionic, non-ionic, and cationic surfactants, making it suitable for a wide range of rinse-off systems.
