CAPB 35% Cocamidopropyl Betaine Amphoteric Surfactant

CAPB 35% for Personal Care and Household Cleaning Formulations

YARUN CAPB 35%, also known as Cocamidopropyl Betaine or CAB-35, is a versatile amphoteric surfactant developed for personal care, household cleaning and liquid detergent formulations.

It can be combined with common anionic, nonionic and cationic surfactants to support foam stability, viscosity adjustment and formulation mildness. CAPB 35% is particularly suitable for use with SLES, AOS and SLS in shampoo, hand wash, body wash, liquid soap and dishwashing liquid.

Amphoteric Compatibility · Stable Foam · Flexible Formulation Support

Final product performance depends on the complete formula, surfactant ratio, pH, electrolyte level, processing conditions and approved application testing.

Why Choose CAPB 35%?

Compatible with Multiple Surfactant Systems

CAPB 35% is compatible with commonly used anionic, nonionic and cationic surfactants. It can be incorporated into different cleansing systems according to the required foam, viscosity and application positioning.

Foam Stability and Viscosity Support

When used in a properly balanced formulation, CAPB can help create finer and more stable foam and support viscosity development in selected surfactant systems.

Suitable for Mild Cleansing Formulations

CAPB is widely used as a co-surfactant in personal care and household cleaning products where formulators want to balance cleansing performance, foam quality and perceived mildness.

Cross-Category Application Value

One raw material can support shampoo, hand wash, body wash, facial cleanser, liquid soap, dishwashing liquid and selected household cleaning projects, making it suitable for manufacturers and distributors serving several finished-product categories.

Recommended Applications

• Shampoo and baby shampoo formulations
• Hand wash and liquid soap
• Body wash and shower gel
• Facial cleansing products
• Dishwashing liquid
• Liquid laundry detergent
• Household and institutional cleaning products
• Car wash shampoo and selected industrial cleaners

CAPB 35% in Surfactant Formulations

CAPB 35% with SLES 70%

CAPB and SLES 70% are commonly combined in shampoo, hand wash, body wash, liquid soap and dishwashing formulations. SLES provides the primary cleansing and foaming function, while CAPB supports foam quality, viscosity development and formulation mildness.

CAPB 35% with AOS

CAPB can be combined with AOS in high-foam liquid cleansing and household cleaning systems where formulators require balanced foam, cleaning performance and surfactant compatibility.

CAPB 35% with SLS

In selected personal care and cleaning systems, CAPB can be used with SLS to adjust foam character and support the overall surfactant balance.

The appropriate surfactant ratio should be determined according to the finished product, target viscosity, pH, electrolyte content, cost target and approved performance testing.

Frequently Asked Questions

1. CAPB 35% vs SLES 70%: What Is the Difference?

SLES is generally used as a primary anionic cleansing surfactant. CAPB is an amphoteric co-surfactant used to support foam stability, viscosity and formulation mildness. They are often used together rather than treated as direct substitutes.

2. What Products Can CAPB 35% Be Used In?

It is commonly used in shampoo, hand wash, body wash, facial cleanser, liquid soap, dishwashing liquid, liquid detergent and selected household cleaning formulations.

3. Is CAPB 35% Suitable for Dishwashing Liquid?

Yes. It can be combined with suitable primary surfactants to support foam stability, viscosity and hand-feel. The final ratio should be confirmed through formulation testing.

4. Can CAPB 35% Be Combined with SLES, AOS or SLS?

Yes. CAPB is compatible with these commonly used anionic surfactants, but the correct ratio depends on the target product, pH, salt level, viscosity and required performance.

5. Does CAPB 35% Automatically Make a Formula Mild?

No single raw material determines finished-product mildness. CAPB can support a milder surfactant balance, but the complete formula and finished product must be evaluated.

6. What Should Buyers Check When Evaluating CAPB 35%?

Buyers should check appearance, solid content, active matter, sodium chloride, pH, free amine, color, packaging condition and batch COA consistency.

7. Can Samples and Technical Documents Be Provided?

Available samples, product specifications, COA, SDS and packaging information can be provided according to the project stage and commercial requirements.
