Any other information on results incl. tables
Discrete or patchy to moderate and confluent erythema was noted at the intradermal induction sites of test group animals. No skin reactions were noted at the intradermal induction sites of control group animals. Discrete or patchy erythema was noted at the topical induction sites of all control group animals at the 1 -hour observation. No skin reaction were noted at the topical induction sites of control group animals at the 24 -hour observation. Bleeding from the intradermal injection sites was noted in all test group animals and four control group animals at the 1 -hour observation.
Applicant's summary and conclusion
- Interpretation of results:
- sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material produced a 90% (9/10) sensitisation rate and was classified as an extreme sensitiser to guinea pig skin under the conditions of the test. The test material produced a sensitisation rate of more than 30% and therefore, will be classified as skin sens. 1, H317 according to GHS/CLP
classification criteria. - Executive summary:
The substance was tested in a skin sensitisation study in the Guinea Pig (Magnusson and Kligman Maximisation Method) according to OECD 406, and GLP in year 2001. The test material produced a 90% (9/10) sensitisation rate and was classified as an extreme sensitiser to guinea pig skin under the conditions of the test. The test material produced a sensitisation rate of more than 30% and therefore, will be classified as skin sens. 1, H317 according to GHS/CLP classification criteria.
