An epidemic of allergic contact dermatitis caused by a new allergen, caprylhydroxamic acid, in moisturizers

Abstract

We found a new contact allergen, caprylhydroxyamic acid, which caused an epidemic of allergic contact dermatitis in patients using moisturizers containing this preservative. Whether the sensitizing capacity of caprylhydroxamic acid depends on the other chemicals used in Apobase® moisturizers needs further investigation.
