As market demand continues to expand, reliable supply chain capabilities have become critical.

7. Excellent Physical & Chemical Stability

The product demonstrates outstanding chemical stability during transportation, storage and use, with a typical shelf life of 12 months.

1. Personal Care Products (Core Application)

CAB-35 is a mild amphoteric surfactant with excellent compatibility with all types of surfactants.

Shampoos & Body Washes: Used in mid-to-high end shampoos and body washes to enhance hair and skin softness, improve combability, increase lubrication during wet washing and dry combing performance. It also significantly reduces the irritation of anionic surfactants in the formulation. Recommended dosage: 2% – 12%.

Baby Care Products: The mildness and low irritation properties of Cocamidopropyl Betaine make it ideal for formulating baby shampoos, baby bubble baths and baby skin care products. It is a key ingredient in many high-quality baby cleansers.

Facial Cleansers & Hand Soaps: Acts as a primary or auxiliary surfactant, producing rich, creamy foam and delivering a gentle, moisturizing skin feel.

2. Household & Industrial Cleaning

This product exhibits excellent detergency, wetting and hard water resistance, playing an important role in household detergents and hard surface cleaning.

Laundry Detergents & Dishwashing Liquids: Functions as a thickener and foam stabilizer in liquid detergents, improving formulation stability and apparent viscosity.

Hard Surface Cleaners: Used in kitchen and bathroom hard surface cleaning to effectively remove oil stains and enhance wetting and spreading performance.

Q1: What is Cocamidopropyl Betaine?

A: Cocamidopropyl Betaine (INCI Name: Cocamidopropyl Betaine, Common Abbreviations: CAPB / CAB, CAS 61789-40-0) is a mild amphoteric surfactant derived from natural coconut oil fatty acids and dimethylaminopropylamine. It appears as a colorless to pale yellow transparent liquid, with excellent foaming, thickening, gentle cleansing and antistatic properties. It is the most widely used mild surfactant in modern personal care formulations.

Q2: What is CAB-35? What grades do you offer?

A: CAB-35 refers to the most common commercial grade of Cocamidopropyl Betaine with 35% active matter content. As a source manufacturer, we provide multiple grades to meet different formulation needs:

CAB-30: 30% active matter, cost-effective for general cleaning products

CAB-35: 35% active matter, most widely used, best balance of performance and cost

CAB-45: 45% active matter, high concentration for high-efficiency formulations

High-purity grade: Low DMAPA and amidoamine content, ideal for baby and sensitive skin products

Q3: What is the recommended dosage of Cocamidopropyl Betaine?

A: Dosage varies by product type (calculated based on 35% active matter content):

Shampoos & body washes: 2.0% – 12.0%

Baby care products: 2.0% – 8.0% (optimal for tear-free formulations)

Facial cleansers & hand soaps: 3.0% – 10.0%

Dishwashing liquids & laundry detergents: 1.0% – 5.0%

Hard surface cleaners: 0.5% – 3.0%

Q4: Is Cocamidopropyl Betaine safe for babies and sensitive skin?

A: Yes, Cocamidopropyl Betaine is exceptionally gentle and is the gold standard ingredient for baby care products. Its large molecular size prevents skin penetration, and its amphoteric nature reduces eye irritation by 80% compared to sulfate-based surfactants. When used within recommended dosages and in high-purity grades, it is safe for even the most sensitive skin and eyes.

Q5: Can Cocamidopropyl Betaine cause skin irritation?

A: When properly purified, Cocamidopropyl Betaine has an extremely low irritation potential. Any reported skin reactions are almost always caused by trace impurities such as residual DMAPA (dimethylaminopropylamine) and amidoamine, not the CAPB itself. Our high-purity grades strictly control these impurities to minimize sensitization risk.

Q6: What is the difference between Cocamidopropyl Betaine and Coco Betaine?

A: They are two distinct chemicals that are often confused:

Cocamidopropyl Betaine (CAPB): CAS 61789-40-0, synthetic, milder, more biodegradable, lower irritation

Coco Betaine: CAS 68424-94-2, natural, more irritating, less biodegradable

CAPB is the preferred choice for modern personal care formulations due to its superior safety and performance profile.

Q7: Is Cocamidopropyl Betaine sulfate-free?

A: Yes, Cocamidopropyl Betaine is completely sulfate-free. It is the most common co-surfactant used in sulfate-free formulations, where it compensates for the reduced foaming and cleansing power of sulfate-free primary surfactants while maintaining mildness.

Q8: What are the core functions of Cocamidopropyl Betaine?

A: As a multifunctional amphoteric surfactant, it provides:

Superior mildness: Significantly reduces the irritation of anionic surfactants

Excellent foaming: Produces rich, creamy and stable foam

Synergistic thickening: Dramatically increases viscosity when combined with anionic surfactants, reducing sodium chloride usage

Antistatic & conditioning: Improves hair combability and skin feel

Broad compatibility: Works with all types of surfactants (anionic, cationic, non-ionic)

Q9: What are the storage and packaging requirements?

A:

Store in a cool, dry and well-ventilated place, away from direct sunlight

Keep containers tightly sealed to prevent contamination

Shelf life: 12 months from the date of manufacture under proper storage conditions

Standard packaging: 200kg plastic drums or 1000kg IBC totes
