Cocamidopropyl Betaine (CAPB)
كوكاميدوبروبيل بيتين (CAPB)
Amphoteric surfactant · CAS: 61789-40-0
Milder, coconut-derived - but a recognised contact allergen for some.
Why this verdict
GHS-hazardous (irritant/allergen/possible carcinogen) but a legitimate, common surfactant - flagged.
What It Is
A coconut-derived 'gentle' foam booster used in mild washes and shampoos.
Marketed as the gentle, coconut-derived surfactant - and it is milder. But it's a recognised contact allergen (it was 'Allergen of the Year' in 2004), driven by manufacturing by-products, and hairdressers show a measurably higher allergy rate. Fine for most; a known trigger for the sensitised.
