Cocamidopropyl betaine is an amphoteric surfactant used increasingly in cosmetic products. We describe 20 cases of cosmetic allergy to cocamidopropyl betaine; all were caused by shampoo or shower gel. 8 patients were hairdressers, who had occupational allergic contact dermatitis from shampoos. We recommend patch testing cocamidopropyl betaine 1% aq. routinely in hairdressers with dermatitis of the hands, and in all patients suspected of suffering from cosmetic allergy.
