Applicant's summary and conclusion
- Interpretation of results:
- other: Skin Sens 1B, according to the CLP Regulation (EC) No 1272/2008
- Conclusions:
- Test item caused skin reactions after challenge in all treated animals
- Executive summary:
To assess the allergenic potential of test item in albino guinea pigs the Maximization-Test of B. Magnusson and A.M. Kligman (1969) was used.
Five males were used as control group and 10 males were used as test group.
The highest non-irritating test article concentration used for challenge application was 25 % in bi-distilled water.
All treated animals of the test group showed erythematous skin reactions 24 and 48 hours after epidermal challenge exposure and the test material is judged skin sensitising.
Conclusion
Skin sensitizer; more than 30 % responding at an intradermal induction dose higher than 1 %.
