Mild, foam-boosting co-surfactant
Increases foam and reduces the irritation of anionic surfactants.
CAPB
Cocamidopropyl Betaine (CAPB) Supplier from China
Cocamidopropyl betaine (CAPB) is a mild amphoteric surfactant used in shampoos, body washes, hand soaps and household cleaners to boost foam, build viscosity and reduce irritation. SUNCHEM supplies CAPB mainly as the 35% active grade (CAB-35), a light-yellow liquid shipped in IBC totes, with a batch COA on every shipment.

Product overview & key benefits
CAPB is made from coconut fatty acids, dimethylaminopropylamine and sodium chloroacetate. It is compatible with anionic, cationic and nonionic surfactants; combined with anionics such as SLES it increases foam, thickens the formula with salt, and makes the product milder on skin and eyes. It is used in shampoos, body washes, facial cleansers, hand soaps, dishwashing liquids and household cleaners.
CAPB is supplied as an aqueous solution, so active matter — not “assay” — is the number to compare. Our main grade is CAB-35, with about 35% active matter.
Builds viscosity
Thickens SLES-based formulas with salt, reducing the need for other thickeners.
Specified on your terms
We quote against your active matter, NaCl, free amine and color and send the batch COA for each lot.

Selection & comparison
Choosing the right CAPB grade
| Your requirement | What usually works |
|---|---|
| Shampoos and body washes | Personal-care grade with low free amine and amidoamine |
| Dishwashing and household cleaners | Standard CAB-35; agree active matter and color |
| Salt-sensitive formulas | Ask for low-salt grade |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Mainly IBC totes; drums on request. Tell us your unloading set-up with your inquiry.
Storage
Store in closed containers, protected from freezing and direct heat. Mix before use if it has been stored cold.
From first email to approved supply
Name the end use
Personal care, household or industrial: free-amine and color limits follow from it.
Compare the numbers that matter
Active matter, solids, NaCl, free amine (DMAPA), amidoamine, pH and color.
Compare on active matter
Prices only compare on the same active content; convert offers to 100% active before deciding.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
