Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- There is no skin sensitisation study available with the target substance. Data generated with LABS is considered pivotal to this endpoint. The target substance is considered to be non sensitising and therefore not to be classified according to CLP Regulation
