Potential occupational exposures

What are the reactions to coconut diethanolamide allergy?

Coconut diethanolamide can rarely cause contact allergic dermatitis, particularly on the hands. Leave-on products (hand-protection foams) cause sensitisation much more rapidly (2-3 months) than rinse-off products (hand-washing liquids; 5-7 years).

Am I allergic to coconut diethanolamide?

Coconut diethanolamide contact allergy is diagnosed by a positive patch test to coconut diethanolamide.

Treatment of contact dermatitis due to coconut diethanolamide exposure

If you are diagnosed with coconut diethanolamide allergy then avoid products which contain this. Read product labels. It may take 2-3 weeks of avoiding exposure before improvement in the dermatitis occurs.

Standard treatment is used for the dermatitis i.e. topical corticosteroids and emollients.
