Product Description
What Is Cocamidopropyl Betaine?
Cocamidopropyl Betaine is an amphoteric surfactant commonly derived from coconut oil. Its mildness and superior foaming qualities make it a popular ingredient in personal care and home goods like shampoos, body washes, and face cleansers. CAPB acts as a mild cleanser and conditioner, making it ideal for sensitive skin and hair, while also improving the viscosity and foam stability of the formulations.
Preparation:
Cocamidopropyl Betaine is produced through a reaction between fatty acids derived from coconut oil (cocamide) and 3-dimethylaminopropylamine. The process involves the following steps:
- Reaction: Fatty acid (from coconut oil) is reacted with 3-dimethylaminopropylamine under controlled conditions.
- Neutralization: The betaine surfactant is created by neutralizing the reaction mixture.
- Purification: The product is then purified, filtered, and distilled to remove impurities, yielding a clear to pale yellow liquid.
