Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: other: EU GHS
- Conclusions:
- On the basis of these results, under the experimental conditions applied, the test substance did not appear to possess sensitizing capacity.
- Executive summary:
The structural analogue was tested to be non sensitising to the skin of guinea pigs in a study according to OECD-Guideline 406. Since EC 700-397-7 is a near analogue to the test substance (EC 413-750-2), the experimental data from this substance were used in a read-across approach.
