Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- None of the animals within the study have showed signs of sensitisation. Therefore the test material has been classed as not sensitising to the skin.
- Executive summary:
The study has been conducted according to EU Method B6 of Directive 92/69 EEC. The test material has been determined to show no signs of sensitisation, as none of the animals within the study have shown signs of skin sensitisation.
