[Allergic eczematous contact dermatitis due to fatty acid polypeptide condensates (author's transl)].

After an electrocardiogram an eczematous contact dermatitis was found on the skin of a 34-year-old soldier, where the contact of the leads had been fixed to the chest and extremities. 5 months later, he caught an eczematous contact dermatitis which spread over the face after irrigation of the external auditory meatus. In both cases, the contact allergen was a fatty acid polypeptide condensate. This article describes the production, properties and application of the fatty acid polypeptide condensates as well as effects and side-effects in comparison to other detergents.
