What Is Cocamidopropyl Betaine?
Cocamidopropyl Betaine is a classic zwitterionic amphoteric surfactant derived from renewable coconut-oil fatty acid. At room temperature it is transparent pale-yellow liquid with 30% active substance content. Its molecular structure carries both positive and negative charges, exhibiting different charge characteristics under different pH environments.
CAPB can work synergistically with anionic, non-ionic and cationic surfactants. It boosts fine stable foam, builds formulation viscosity, and significantly lowers the irritation of harsh anionic surfactants such as SLES/SLS. It also brings mild conditioning and anti-static performance for skin and hair.
Different from anionic surfactants like Sodium Laureth Sulfate, CAPB features much lower skin & eye irritation, works well in hard-water conditions, and is a core raw material for sulfate-free, baby-safe and sensitive-skin cleansing products. Aogebio supplies high-purity cosmetic-grade Cocamidopropyl Betaine in bulk, offering free samples, full qualification documents and global one-stop shipping services for cosmetic manufacturers.
Core Advantages Of Our Cocamidopropyl Betaine
High-Purified Cosmetic-Grade Raw Material
Adopts multi-step purification process, strictly controls free dimethylaminopropyl-amine impurity, low peculiar odor, stable active-substance content, suitable for high-grade mild cleansing and baby-care cosmetic formulas.
Excellent Foam-Boosting & Foam-Stabilizing Performance
Generates abundant, fine and creamy foam; foam remains stable even under hard-water environment; effectively improves foam quality when compounded with anionic surfactants, avoiding quick-collapse foam issues.
Significant Irritation-Reducing Capacity
When compounded with anionic surfactants such as SLES, it greatly reduces skin and mucosa irritation, relieves tight and dry feeling after washing; ideal for sensitive-skin and no-tear baby cleansing formulas.
Viscosity-Building & Formulation-Stabilizing
Works together with anionic surfactants to increase system viscosity, helps liquid cleansing products reach target thickness, improves low-temperature stability and prevents stratification of finished products.
Broad-Spectrum Surfactant Compatibility
Compatible with anionic, non-ionic, amphoteric and cationic conditioning ingredients; adapts to various rinse-off cleansing formula systems, easy for formula development and industrial production.
Conditioning & Anti-Static Property
Delivers soft skin feeling after rinsing; reduces hair static-electricity, improves wet-combing and dry-combing performance of shampoo products.
Stable Batch Quality & Flexible Supply
Consistent batch-to-batch active content and physical-chemical indicators, fit for large-scale industrial production; support sample testing, small-batch trial order and large-volume bulk customization.
How Cocamidopropyl Betaine Works In Cosmetic Formulations
CAPB is a zwitterionic amphoteric surfactant. In aqueous cleansing systems, its molecules arrange at oil-water interfaces to wrap grease, dirt and sweat, removing contaminants during rinsing.
When compounded with anionic surfactants, mixed micelles are formed, which weaken the aggressive skin-damaging effect of single anionic surfactant, lowering overall formula irritation. Meanwhile it optimizes foam microstructure to get finer, longer-lasting lather. In shampoo systems, partial positive-charge characteristics adsorb onto hair cuticle surface to deliver anti-static and soft conditioning effect. It maintains good surface-active performance within wide pH range (pH 4-8) for most cleansing products.
Main Functions & Cosmetic Application Fields
Core Functional Benefits
- • Mild cleansing agent: remove skin/hair dirt and excess sebum without over-stripping skin barrier
- • Foam booster & stabilizer: produce rich, fine, long-lasting creamy foam, stable under hard-water
- • Irritation reducer: decrease irritation caused by anionic surfactants for gentle cleansing experience
- • Viscosity builder: assist to adjust product viscosity together with other surfactants
- • Hair conditioning & anti-static: reduce hair static, improve combability, leave hair soft and smooth
- • Improve post-wash skin feel: reduce tight-dry sensation after body & facial cleansing
Suitable Cosmetic Formulas
- • Sulfate-free shampoo, 2-in-1 conditioning shampoo, anti-dandruff shampoo
- • Foaming facial cleanser, sensitive-skin gentle cleanser
- • Body wash, shower gel, hand wash liquid soap
- • Baby shampoo, baby bubble bath, infant mild cleansing products
- • Pet cleansing formulas, mild bubble bath products
- • Transparent cleansing liquid, pearl-effect shower-gel systems
Formulation Guide: Dosage, Solubility & Matching Tips
Recommended dosage (based on commercial 30%-active CAPB raw liquid):
- -Shampoo & 2-in-1 hair-care product: 5%-20%
- -Body wash & shower gel: 3%-15%
- -Foaming facial cleanser: 2%-8%
- -Baby no-tear cleansing formula: 4%-12%
Solubility: Fully soluble in water; insoluble in oil phase; add into water-phase or mixed-surfactant phase.
Recommended matching ingredients: Sodium Laureth Sulfate(SLES), Sodium Lauroyl Glutamate, Decyl Glucoside, Guar Hydroxypropyltrimonium Chloride, glycerin, panthenol, sodium chloride (viscosity adjuster).
Formulation Notes:
- -Recommended compound ratio with anionic surfactant: anionic : CAPB = 1:1 ~ 3:1 for optimal foam and mildness effect.
- -Adding sodium chloride can further adjust system viscosity; avoid excessive salt which may trigger stratification.
- -Processing temperature should not exceed 80℃; long-time high-temperature heating will risk hydrolysis and performance decline.
- -Suitable formula pH range: 4.0-8.0; avoid long-term extreme strong-acid or strong-alkali environment.
- -Not recommended for leave-on skincare formulas; mainly designed for rinse-off cosmetic systems.
- -Seal and store under cool-dry condition; avoid freezing, low-temperature may generate slight turbidity; restore to room-temperature and stir evenly for normal use.

Frequently Asked Questions
-
Q1: What is the difference between Cocamidopropyl Betaine (CAPB) and SLES?
A: CAPB is amphoteric surfactant with very low irritation, used for boosting foam, reducing irritation and conditioning; SLES is high-foaming anionic surfactant with stronger detergency but relatively higher irritation. They are often compounded together to balance cleansing power, foam performance and mildness. CAPB is the core option for sulfate-free gentle cleansing products. -
Q2: Can Cocamidopropyl Betaine be used for baby shampoo?
