Application Fields
Daily Chemical Industry Cocamidopropyl Betaine is a mild amphoteric surfactant that can be widely combined with various surfactants. When compounded with other surfactants, it exhibits excellent synergistic effects, reducing the irritation caused by traditional surfactants. It also improves foaming power, producing fine, stable, and abundant foam, and has a high thickening effect. Used in shampoos, foam bath gels, facial cleansers, personal hygiene products and baby cleaning products, industrial cleaning, vehicle cleaning, etc.

Packaging Method

Stability and Storage Conditions
Cocamidopropyl Betaine is relatively stable under normal conditions, but exposure to light, oxygen, and humidity may cause decomposition or deterioration. Therefore, it should be stored in sealed containers to minimize contact with air, and extreme temperatures should be avoided. It is best stored at room temperature in a cool, dry place. Do not mix storage; it should be kept separate from oxidizers, acids, and bases.
