Product Overview
Cocamidopropyl Betaine (CAPB) is a mild amphoteric surfactant widely used as a secondary surfactant in personal care and cleaning formulations. It is commonly combined with anionic surfactants such as SLES and SLS to improve foam performance, reduce irritation and enhance formulation stability.
We supply Cocamidopropyl Betaine (CAPB) in standard 30% grade and higher active 35%+ grade for manufacturers of shampoos, shower gels, liquid detergents and household cleaning products.
What is Cocamidopropyl Betaine (CAPB)?
Cocamidopropyl Betaine is an amphoteric surfactant derived from coconut fatty acids. It contains both positive and negative ionic groups, allowing it to work effectively with different surfactant systems.
CAPB is mainly valued for:
- Foam boosting
- Mild cleansing performance
- Viscosity improvement
- Compatibility with other surfactants
- Reduction of irritation in formulations
Unlike strong primary surfactants, CAPB is usually used as a co-surfactant to improve the overall performance of finished products.

How to Choose CAPB Grade?
Choose CAPB 30% when:
- Producing standard liquid products
- Cost control is important
- Large production volume is required
- Normal surfactant concentration is acceptable
Choose CAPB 35%+ when:
- Producing concentrated formulations
- Higher active content is required
- Reducing water content is preferred
- Transportation efficiency is important
Applications
Personal Care
CAPB is widely used in:
- Shampoo
- Shower gel

FAQ
What is the difference between CAPB 30% and CAPB 35%?
The main difference is active surfactant content. CAPB 30% is the standard grade with around 30% active matter, while CAPB 35%+ provides higher concentration and lower water content.
Which CAPB grade is commonly used?
CAPB 30% is the most commonly used grade because it offers good performance and better cost efficiency for regular formulations.
Is CAPB a primary surfactant?
No. CAPB is usually used as a secondary surfactant to improve foam, mildness and stability together with primary surfactants such as SLES.
