Sensitization to Kathon CG in Geneva and Switzerland
Contact Dermatitis, 1989Between October 1986 and June 1987 we patch tested 420 patients with Kathon CG at 100 ppm and obtained 23 positive reactions (5.5%). The other 5 Swiss university clinics joined our study between January and June 1987 and obtained sensitization rates ranging from 0.7 to 7.5%. The total mean value including Geneva was 3.6%. We did threshold patch testing
