Cocamidopropyl betaine

# Cocamidopropyl Betaine (CAPB 30%)

Cocamidopropyl Betaine is a mild, amphoteric surfactant widely used in personal care and cleansing formulations. Supplied as an aqueous solution containing approximately 30% active matter, it enhances foam quality, improves cleansing performance, and helps increase viscosity when combined with compatible surfactants.

It is commonly used in shampoos, body washes, facial cleansers, liquid hand soaps, and other cleansing products. Its compatibility with anionic and nonionic surfactants makes it an excellent co-surfactant for developing effective cleansing formulations.

ChemSolve Labs supplies Cocamidopropyl Betaine 30% for cosmetic, personal care, and cleaning product development.

Important: A product containing 30% active matter is not 100% pure CAPB. The remaining portion consists mainly of water, sodium chloride, and other constituents. Active matter and total solids are different measurements.

# Key Benefits

• Foam Boosting: Helps produce rich, stable foam in cleansing formulations.
• Mild Cleansing: Can help reduce the harshness of certain anionic surfactant systems.
• Viscosity Enhancement: May help increase viscosity when combined with compatible surfactants and suitable salt levels.
• Formulation Compatibility: Works well with common surfactants such as Sodium Laureth Sulfate (SLES).
• Versatile Applications: Suitable for a wide range of personal care and household cleansing products.
• Easy Formulation: Its water-based liquid form makes it convenient to incorporate into aqueous formulations.

#Recommended Applications

Product Type Primary Function
Shampoo Foam enhancement and cleansing
Body Wash Cleansing and foam stabilization
Facial Cleanser Co-surfactant and foam enhancement
Liquid Hand Wash Cleansing and lather improvement
Baby Wash Co-surfactant in mild products
Dishwashing Liquid Foam enhancement and cleansing
Household Cleaning Products Surfactant and cleaning performance enhancement

The suitability of the ingredient depends on the finished formulation, concentration, and intended application.

# Typical Usage Level

Application Example Starting Range
Shampoo 3–10%
Body Wash 3–10%
Facial Cleanser 2–8%
Liquid Hand Wash 3–10%
Dishwashing Liquid 2–10%

These are general formulation starting ranges, not universal specifications. The optimum level depends on the other surfactants, desired active matter, viscosity, foam profile, and mildness requirements.
