Description of key information

Human cases have shown that contact dermatitis patients, for whom a rubber intolerance was often present, occasionally reacted positively to 1,3-diphenylguanidine in the patch test. Cross-reactions with other skin sensitizers rather than a direct sensitising effect of 1,3-diphenyl guanidine cannot be excluded.
