Abstract
Contact allergy to CAPB is now infrequent, partly because of the increasing use of new non-irritating surfactants that have been introduced on the market in the last decade. However, cases of patients allergic to commercial CAPB who only react to DMAPA -and not to CAPB- when they are patch tested are still being reported. DMAPA itself, and other molecules like amidoamine, would be the true allergens, and some cases of CAPB allergy are therefore being overlooked because DMAPA is not always included in the cosmetics series. CAPB may no longer be necessary in patch tests, as DMAPA seems to be the principal allergenic fraction in this surfactant, and also because manufacturers of skin allergens currently prepare CAPB extracts that are so pure that they are no longer a good screening tool for contact allergy to commercial CAPB.
