Cross-reactions between xanthates and rubber additives.

Background: We previously described allergic contact dermatitis from xanthates used in the recovery of metals from mining ores. We observed cross-reactions with carbamates, believed to be due to the common "dithio" nucleus shared by both groups.

Objective: The present study was undertaken to establish the rate of cross-reactions between xanthates and rubber additives.

Occupational allergic contact dermatitis from xanthates and carbamates in mining processes.

The objective of this article is to describe allergic contact dermatitis from sodium isopropyl xanthate, potassium amyl xanthate, and carbamates in a geotechnician, to discuss possible cross-reactions, and to report the widespread use of carbamates and mercaptobenzothiazole in mining processes.
