What Is Cocamidopropyl Betaine 30%?

Cocamidopropyl Betaine 30% (CAPB 30%) is a mild amphoteric surfactant supplied as a clear to pale yellow liquid, widely used as a secondary surfactant in personal care and liquid cleaning formulations. With an active matter content typically in the range of 29–32%, it offers a balanced combination of foaming performance, mildness, and viscosity enhancement.

CAPB 30% is highly compatible with anionic, nonionic, and cationic surfactants, making it an essential component in surfactant systems to improve foam quality, reduce irritation, and stabilize formulations. It is commonly used in shampoos, body washes, facial cleansers, and sulfate-free systems where gentle cleansing and formulation flexibility are required.

Key Functions

Cocamidopropyl Betaine 30% functions as a versatile amphoteric surfactant, enhancing mildness, foam performance, and formulation stability across personal care and cleaning applications.

Mild Cleansing Performance
Provides effective removal of dirt, oil, and impurities while maintaining lower irritation compared to traditional anionic surfactants, making it suitable for daily-use formulations.
Foam Boosting and Stabilization
Enhances foam volume, density, and stability when combined with primary surfactants, improving overall product performance and user experience.
Viscosity Building Support
Works synergistically with anionic surfactants such as SLS or SLES to increase viscosity, enabling better control of formulation thickness and texture.
Surfactant Compatibility
Highly compatible with anionic, nonionic, and cationic surfactants, allowing flexible formulation design and improved system stability.
Mildness Enhancement
Reduces the harshness of primary surfactants, helping formulators create gentler cleansing systems suitable for skin and hair care.
Improved Sensory Performance
Contributes to smoother skin feel, better rinseability, and enhanced overall formulation aesthetics in finished products.

Applications

Cocamidopropyl Betaine 30% is widely used in personal care and liquid cleaning formulations due to its mildness, foam-enhancing performance, and formulation versatility.

Shampoos and Hair Care Products
Improves foam quality, reduces irritation from primary surfactants, and supports balanced cleansing performance in hair care formulations.
Body Washes and Facial Cleansers
Provides gentle cleansing and stable foam, making it suitable for daily-use skin care products with improved skin compatibility.
Baby Care and Mild Formulations
Used in baby shampoos and sensitive-skin cleansers where low irritation and mild surfactant systems are required.
Sulfate-Free Formulations
Acts as a key surfactant component in sulfate-free systems, providing foam stability and cleansing support when combined with mild surfactants.
Dishwashing Liquids and Household Cleaners
Enhances foam performance and grease removal in liquid cleaning products while improving formulation stability.
Specialty Cleansing Products
Used in oral care and specialty formulations requiring mild foaming performance and broad surfactant compatibility.

FAQs

What makes CAPB 30% different from other CAPB grades?

The main difference lies in active matter concentration. CAPB 30% is the most widely used liquid grade, offering a balanced combination of performance, mildness, and ease of use for personal care and liquid formulations.

Why is CAPB commonly used with SLS or SLES?

CAPB is used as a secondary surfactant to reduce irritation, improve foam quality, and enhance viscosity when combined with primary anionic surfactants such as SLS or SLES.

Is CAPB 30% suitable for sulfate-free formulations?

Yes, CAPB 30% is widely used in sulfate-free systems as a mild surfactant and foam stabilizer when combined with other non-sulfate surfactants.
How does CAPB 30% behave in different pH conditions within formulations?

CAPB is an amphoteric surfactant whose charge behavior varies with pH. In acidic to neutral conditions, it exhibits cationic characteristics that enhance mildness and conditioning effects, while in alkaline systems it behaves more like an anionic surfactant, contributing to cleansing and foaming performance. This dual functionality allows CAPB 30% to improve formulation stability, compatibility, and performance across a wide pH range.

How does CAPB compare to Coco Betaine?

CAPB generally provides better viscosity building, foam stability, and formulation compatibility, making it more widely used in personal care and cleansing products.
