Cocamidopropyl betaine is used as a foam booster in shampoos, emulsifying agent, thickener, antistatic agent and rarely an antiseptic agent. Impurities formed during the manufacturing process are thought to increase the prevalence of contact sensitization and mild skin irritations.
Cocamidopropyl betaine: Uses and safety
Cocamidopropyl betaine, or CAPB for short, is an ingredient in many personal care products, including some brands of shampoo, body wash, and soap. Manufacturers also use it to formulate household cleaners and laundry detergent.
Uses and properties of CAPB
- Surfactant: CAPB allows water and oil — two substances that usually repel each other — to interact. This makes it possible to remove oil with water, lifting it from the skin or hair.
- Foam enhancer: In shampoos and body washes, CAPB can help create a rich lather when it comes into contact with water.
- Thickening: CAPB adds viscosity to products, making them thicker and creamier. This is useful in products such as hair conditioners, as it makes them less likely to drip.
