| CAS Number | 61789-40-0 |
| Ionic Type | Amphoteric |
| Abbreviations | CAPB |
Cocamidopropyl Betaine is an amphoteric surfactant used to support foam, mildness, viscosity response, and surfactant compatibility.
Cocamidopropyl Betaine (CAPB) is widely used as an amphoteric co-surfactant in personal care, home care, and HI&I cleaning formulations. It is commonly paired with anionic surfactants to improve foam quality, reduce harshness perception, and help viscosity building in electrolyte-responsive systems.
Commercial CAPB is typically supplied as an aqueous solution. Active matter, sodium chloride, free amidoamine, monochloroacetic acid residuals, and preservative package are supplier dependent.

Review and verify supplier SDS/TDS before handling, scale-up, or commercial use. Concentrated CAPB solutions may cause eye or skin irritation; follow supplier PPE guidance.
Confirm grade purity, residual impurities, preservative system, and regional requirements before use in finished products.
