p-Phenylenediamine sensitization and occupation

Contact Dermatitis, 2010
p-Phenylenediamine (PPD) is an extreme delayed-type skin sensitizer, and is relevant in both occupational and non-occupational exposures.To estimate the prevalence of PPD sensitization in a population of consecutive patients with suspected allergic contact dermatitis who attended units of dermatology or occupational medicine in north-eastern Italy and ...

Sensitization to p-Phenylenediamine

Archives of Dermatology, 1965
p-Phenylenediamine (PPD) from 0.2 mg to 1.6 mg in water or in petrolatum was applied as a patch test to 501 patients with different dermatoses, asthma, hay fever, and venereal diseases. Of these patients 10.6% reacted within the first five days indicating previous hypersensitivity and 14.4% between the sixth and the 16th day indicating the initiation ...
