Applicant's summary and conclusion

Interpretation of results:
Category 1B (indication of skin sensitising potential) based on GHS criteria
Conclusions:
According to (Q)SAR modells: QSAR Toolbox, Toxtree, ChemProp the predicted values indicated that acetoxy-ad-enolether is sensitiser. The result meets the requirement of Hazard Category 1B.
