Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- No signs of erythema and edema were observed at 1.0% ICC and 10% ACC concentrations. Hence, the test chemical was considered to be non-irritating on guinea pigs in the preliminary irritation tests performed for the sensitization study.
- Executive summary:
Preliminary irritation tests were performed for the test chemical in guinea pigs to determine the concentration suitableforthe sensitization study[injection challenge concentration (ICC) and application challenge concentration(ACC)].
In the preliminary irritation study, 4 Albino Hartley guinea pigs of the same sexwereinjected intradermally on the shaved flanks with 0.1 ml aliquots of a range of concentrations of tests material in a suitable solvent. The reactions were examined for size (two largest diameters), erythema and oedema 24 h later and the concentration giving slight but perceptible irritationwith no oedema was selected as the injection challenge concentration (ICC).0.1 ml of the test material in arange of concentrations in a suitable solvent were applied in small circular areas to the shaved flanks of 4 guinea pigs of the same sex.The reactions were examined for erythema 24 hours later and the highest concentration which caused no irritation was selected as the application challenge concentration (ACC).
No signs of erythema and edema were observed at 1.0% ICC and 10% ACC concentrations. Hence, the test chemical was considered to be non-irritating on guinea pigs in the preliminary irritation tests performed for the sensitization study.
