Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance is a mild skin irritant but no classification is requested under CLP Regulation.
- Executive summary:
Three New Zealand white rabbits were treated with 200 mg of test substance occlusively, produced slight erythema of all 3 three animals at 4.5 hours reading. Similar observations were made at 24hr, 48 hr and 72 hours. The skin responses completely resolved by 72 hours reading. Based on the observations, the test substance is a mildly irritating to the dermal tissue of the rabbit.
