Regulatory frameworks exist within the EU to limit the dermal exposure of the general population and workers to chemicals in general, as well as to limit the use of certain substances in cosmetic products. The objective of the study was to investigate and compare toxicological evaluations of dermal exposure performed under current regulatory frameworks. The publicly disseminated hazard information under the respective regulatory frameworks was compiled and compared for the five substances resorcinol, pphenylenediamine, p-aminophenol, N-phenyl-p-phenylenediamine, and diethylene glycol monoethyl ether. A low consistency between evaluations was observed in respect to data coverage and cited dose descriptors. No systematic differences over all five substances were identified from the viewpoint of dermal hazard assessment. The critical effect and corresponding systemic effect dose descriptor was identical for two substances, differed somewhat for two other (a factor of 2 to 2.5). For N-phenyl-p-phenylenediamine a critical effect was only identified under REACH.
