Cocamidopropyl Betaine (CAPB): Mild Amphoteric Surfactant for Personal Care Formulations
As consumers keep pursuing mild‑tolerance cleaning products, demand for gentle surfactants continues to rise. Cocamidopropyl Betaine (CAPB) is a widely‑used amphoteric surfactant and an essential ingredient in modern‑day personal‑care formulations.
CAPB is generally a pale yellow clear viscous liquid. It delivers excellent foaming, foam‑stabilizing and thickening performance. It shows good compatibility with anionic, cationic and non‑ionic surfactants. CAPB can effectively reduce skin irritation caused by surfactants such as AES and LAS. It produces fine, rich foam and leaves little slippery residue upon rinsing.
Main Applications
- Personal Care Shampoos, body washes, facial cleansers and baby‑care products. Thanks to its low‑irritation feature, CAPB is popular for sensitive‑skin and infant‑grade formulas. It optimizes foam performance and mitigates skin & eye irritation.
- Household Cleaning Dishwashing liquids and multi‑purpose cleaners. It improves cleaning power while delivering mild skin feel.
- Industrial Formulations Also applied in textile auxiliaries and foam‑making agents.
Key Specifications & Sourcing Notes
The most common commercial grade is 30% active content, 35% grade is also available. Buyers shall focus on these key indicators: active substance content, free amine value, sodium chloride content and pH value. Excess free amine will cause odor and higher irritation, and greatly affect finished‑product quality.
Note: CAPB may turn hazy under low‑temperature conditions. This is normal physical change. It will return to clear after warming up without performance loss.
Practical Purchasing Tips
- Confirm active content clearly, distinguish between 30% and 35% grades, as they differ in unit price and usage dosage.
- Check COA carefully. Strict control of free‑amine content is critical especially for baby‑care end‑products.
- Standard packaging: 200kg plastic drums or IBC totes. Store in sealed condition, avoid long‑time low‑temperature exposure and direct sunlight.
Driven by global consumer trend toward mild personal care, CAPB remains one of the highest‑volume amphoteric surfactants for its balanced cost‑performance. Steady orders come from domestic cosmetic manufacturers and overseas export markets.
