Description and Uses
Disperse orange 3 is an azo dye which can induce contact dermatitis in workers in the textile industry. Patch tests are frequently positive (about 30%) in hairdressers with a hand dermatitis. It is probably an indicator of contact sensitization to PPD, but disperse orange 3 can also be found in so me semipermanent hair dyes.
Disperse Orange 3 may be used as a test material for investigating its degradation by the white rot fungus?Pleurotus ostreatus and the products obtained upon degradation are determined using UV-visible spectrophotometric and high-performance liquid chromatographic techniques.
