Cocamidopropyl Betaine (CAPB, CAS No.: 4292-10-8) Applications
Cocamidopropyl Betaine (CAPB, CAS No.: 4292-10-8) is a classic amphoteric surfactant featuring excellent mild detergency, high foaming performance, thickening ability and outstanding compatibility. With low irritation, good hard water resistance and stable acid-base adaptability, it is widely compounded with anionic, cationic and nonionic surfactants. Due to its versatile functional properties, it is extensively applied in daily chemicals, industrial cleaning and fine chemical industries. Its main application areas include the following:
1. Daily Chemicals and Personal Care Industry
This represents the most significant application field of cocamidopropyl betaine.
Hair Care Products:
CAPB is a core compound ingredient in shampoos and hair conditioners. It can reduce the irritation of anionic surfactants, produce fine, rich and stable foam, and effectively clean scalp oil and dirt. Meanwhile, it has excellent antistatic and softening effects, reducing hair tangling and improving hair smoothness.
Skin Care Cleansing Products:
It is widely used in facial cleansers, body washes and mild cleansing mousses. Characterized by low skin irritation and weak degreasing power, it protects the skin’s sebum barrier while achieving efficient cleansing, suitable for sensitive skin and infant care formulations.
Oral Care Products:
Cocamidopropyl betaine is applied in mild toothpaste and mouthwash formulations as a foaming and cleansing auxiliary, improving product foam fineness and reducing oral irritation.

2. Household and Industrial Cleaning Industry
Cocamidopropyl betaine has excellent synergistic cleaning and foam stabilization effects, widely used in various cleaning formulations:
Household Cleaning Agents:
Used in dishwashing liquids, multi-purpose household cleaners and laundry detergents. It enhances decontamination and grease removal efficiency, stabilizes foam in hard water environments, and reduces product irritation to hands.
Industrial Mild Cleaners:
Applied in low-corrosion industrial surface cleaners, equipment degreasers and textile cleaning agents, adapting to complex water quality and improving cleaning uniformity.

3. Textile Printing and Dyeing Industry
In textile processing, cocamidopropyl betaine is mainly used as:
A textile softener and antistatic agent for cotton, wool and synthetic fibers;
A dyeing auxiliary and leveling agent to improve dye dispersion and enhance dyeing uniformity;
A low-irritation scouring agent for fine fabric pretreatment.
4. Cosmetic and Fine Chemical Formulation
CAPB plays an irreplaceable role in fine chemical and cosmetic compounding:
Formula Synergist:
Compounded with SDS, AESA and other surfactants to reduce formula irritation, increase foam volume and improve product mildness.
Thickening Stabilizer:
It has natural thickening properties, which can effectively increase system viscosity, stabilize product formulas, and prevent delamination and precipitation of daily chemical products.
5. Pharmaceutical and Disinfection Industry
Cocamidopropyl betaine is widely used in pharmaceutical and disinfection formulations due to its bacteriostatic and mild properties:
Disinfectant Auxiliary:
Compound with quaternary ammonium salts to prepare mild skin disinfectants and environmental disinfectants, improving the dispersion and bactericidal efficiency of active ingredients.
Pharmaceutical Cleansing Preparations:
Used in external pharmaceutical cleansing formulas to reduce irritation and improve the spreadability of preparations.

6. Oilfield and Mineral Processing Industry
Cocamidopropyl betaine has unique application value in oilfield and mineral industries:
Oilfield Foaming Agent:
Used in oil well foam flooding and well washing operations, with high foam stability under high temperature and high salinity conditions, improving oil displacement efficiency.
Mineral Flotation Auxiliary:
Serves as a foaming and wetting agent in non-metallic mineral flotation, optimizing mineral separation effect and improving ore recovery rate.
7. Other Industrial Applications
Additional applications of cocamidopropyl betaine include:
Wetting and dispersing additives for pesticide formulations;
Foam stabilizers and softening additives for leather processing;
Auxiliary surfactants for industrial wastewater deoiling and purification treatment.
