What is it?
Diphenyl thiourea is an accelerator and activator for neoprene rubber and ethylene-propyline-diene terpolymers for the improvement of the flowing properties of the starting materials in the production of rubber. It is a fixative in photography and photocopy paper.

How can I avoid it?
Skin contact with Diphenyl thiourea is required for it to cause a rash. Discontinuation of exposure to products containing Diphenyl thiourea should result in improvement and/or resolution of your dermatitis. By law, all products made in the US for topical use have ingredients listed either on the product package or the box that contains it, so check the labeling of ingredients in your products. At work, request a Material Safety Data Sheets (MSDS) to help identify potential sources of exposure.Patients who are photoallergic to thiourea should either avoid contact with photocopy paper and photographic developing or should change to a non-thiourea containing process. Althought very unlikely, such patients may react to certain rubber products or adhesive agents and should discuss any such problems with their physician.
