Results and discussion
- Positive control results:
- The non-irritating test article concentration used for the challenge application of the positive control was 15 % in mineral oil. 95 % of the animals were observed with positive skin reactions after treatment with a non-irritating concentration of 15% in mineral oil. No skin reaction were observed in the negative control group. According to the rating of allergenicity by Magnusson and Kligman, the positive control tested under the test conditions is considered as an extreme sensitizer.

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified within the CLP Regulation (EC1272/2008)
- Conclusions:
- The test substance is not sensitising under the condition of the test.
- Executive summary:
In order to assess the cutaneous allergenic potential of the test substance, the Maximization-test in accordance with OECD Guideline No. 406 was carried out in 30 (20 test and 10 control) albino guinea pigs.
According to the procedures used in this experiment, no differences between the test group and the vehicle-treated controls where evident after epidermal challenge application of the test substance. The test item is considered to possess no skin sensitizing (contact allergenic) potential in albino guinea pigs.
