Cocamidopropyl Betaine is typically a colorless to pale yellow viscous liquid at room temperature and is readily soluble in water. As a zwitterionic surfactant, it exhibits mild chemical properties with very low irritation potential. It remains stable in acidic, alkaline, and hard water conditions, while possessing excellent foaming, foam-stabilizing, and thickening capabilities. Based on its mild and synergistic characteristics, its primary application is as a key co-surfactant in mild personal cleansing products (such as baby care items, premium shampoos, body washes, and facial cleansers). It is often formulated in combination with primary surfactants like Sodium Laureth Sulfate (AES) and Sodium Lauryl Ether Sulfate (SLES) to significantly reduce formulation irritation while enhancing foam richness and longevity.
