Coconut diethanolamide (CDFA). manufactured from coconut oil, is widely used as a surface‐active agent in hand gels. hand‐washing liquids, shampoos, and dish‐washing liquids. CD HA has rarely caused allergic contact dermatitis. During NS5 IW2, we investigated 6 patients with occupational allergic contact dermatitis caused by CDEA. 2 became sensitized from a barrier cream, 3 from a hand‐washing liquid, and 1 had been exposed both to a hand‐washing liquid and to a metalworking fluid containing CDEA. Leave‐on products (hand‐protection foams) caused sensitization much more rapidly (2 3 months) than rinse‐off products (hand‐washing liquids: 5–7 years). Due to the extensive use of CDEA and the lack of proper declaration of products, it is difficult to avoid CDEA exposure. No contact allergy to another coconut‐oil‐derived sensitizer (cocamidopropyl betaine) was found in the patients.
