Introduction:
Cocamidopropyl Betaine (CAPB) is a mild amphoteric surfactant derived from coconut oil, widely used in personal care and cleansing formulations. It serves as a foam booster, viscosity builder, and co-surfactant, especially in products designed for sensitive skin, baby care, and sulfate-free systems. CAPB is known for its gentle cleansing action, making it ideal for shampoos, body washes, face cleansers, and hand washes.
What is CAPB?
Cocamidopropyl Betaine is a clear to pale yellow liquid with mild odor and is compatible with anionic, cationic, and non-ionic surfactants. It provides rich lather, skin-conditioning, and anti-static properties, improving overall mildness and feel of the final formulation. It also helps reduce the irritation potential of harsher surfactants like SLES or SLS.
Applications of Cocamidopropyl Betaine:
-
Shampoos & Hair Cleansers:
-
Provides stable, creamy foam and reduces irritation caused by sulfates.
-

✅ FAQs (Frequently Asked Questions):
Q1. Is Cocamidopropyl Betaine sulfate-free?
Yes. It is a sulfate-free, coconut-derived surfactant, commonly used in gentle formulations.
Q2. Can CAPB be used in baby products?
Absolutely. It is one of the most trusted surfactants for baby shampoos due to its low irritancy.
Q3. Does CAPB cause allergic reactions?
Rarely. It’s considered safe and mild, but like all ingredients, a patch test is recommended.
Q4. What is its role in formulations with SLES?
It acts as a secondary surfactant, boosting foam, reducing harshness, and improving skin feel.
