Product Description
Cocamidopropyl betaine (CAPB) CAS 61789-40-0, Low Irritation Amphoteric Surfactant with Excellent Foam, Outstanding Surfactant Compatibility
Product Overview

Cocamidopropyl betaine is an amphoteric surfactant featuring a quaternary ammonium salt group as the cationic part and a carboxyl group as the anionic part. Derived primarily from coconut oil and its derivatives, this substance offers low irritation, thickening, antistatic, softening, bactericidal properties, hard water resistance, and excellent biodegradability.

Easily soluble in water with strong pH stability, CAPB is commonly combined with various surfactants to significantly enhance the softness, conditioning, and low-temperature stability of washing products. It is widely utilized in daily chemical products including shampoos, shower gels, facial cleansers, and oilfield oil displacement agents.

Performance Characteristics
  • Low Irritation: Non-irritating and non-allergenic to skin and mucous membranes, suitable for formulating mild personal care products
  • Excellent Solubility & Compatibility: Easily soluble in water and readily compatible with other surfactants to form transparent liquids or colloids
  • Foaming & Thickening Properties: Produces stable, fine foam; significantly increases product viscosity when compounded with anionic surfactants
  • Strong Detergent Power: Excellent detergency for effectively removing stains and grease
  • Softening, Antibacterial & Antistatic Properties: Improves softness, conditioning, and low-temperature stability while providing antibacterial and antistatic benefits
Packaging & Shipping

Packaging: Typically packaged in 200 kg polyethylene plastic drums, 200 kg plastic-coated iron drums, or ton containers.

Storage: Store in a cool, dry place away from direct sunlight and high temperatures. Ensure containers are tightly sealed to prevent moisture absorption and deterioration.

Applications
  • Daily Chemical Products: Mid-to-high-end shampoos, shower gels, hand soaps, foaming facial cleansers, household detergents, and mild baby care products
  • Textile Printing & Dyeing: Excellent softening conditioner in hair and skincare formulations; softening treatment agent in textile industry
  • Oilfield Extraction: Viscosity reducer, oil displacement agent, and foaming agent for improving tertiary oil recovery rates
Usage Notes

1. While CAPB has low skin irritation and is mild, direct contact with skin and eyes should be avoided. Appropriate protective equipment should be worn during use.

2. With good biodegradability meeting environmental requirements, attention should be paid to reducing wastewater discharge and environmental pollution during production and use.
