Summary

In 1987, the rate of sensitization to Kathon CG in the six main Swiss Dermatology Clinics was 3.5% (87 positive reactions in 2491 patients). In 1005 tested men, 30 positive reactions were observed (3%), and in 1486 tested women, 57 positive reactions (3.8%). In about one-third of our patients, relevance could be confirmed clinically by the disappearance of dermatitis when the use of Kathon-containing creams was discontinued, by a positive patch test reaction with the Kathon-containing cosmetic, or (in Geneva) by threshold patch testing.
