Applicant's summary and conclusion

Interpretation of results:

study cannot be used for classification

Conclusions:

Executive summary:

The substance was tested for acute inhalation toxicity. No details are available on the study design, doses/concentrations and experimental results. The study was conducted on rats. Exposure occurred by inhalation of an atmosphere saturated with vapor, conducted through a layer of 5 cm of the test item.

No deaths occurred at the highest exposure time of 8 hours, however, no indication regarding the exposure concentration was present. For this reason, the performed study is not suitable for classification purpose.
