Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LC50
- Based on:
- test mat.
- Exp. duration:
- 7 h
- Remarks on result:
- other: No death were observed during a 7 h-inhalation period of the test animals in a saturated atmosphere at room temperature. As the saturation vapour pressure is very low (less than 0.001 Pa at 20 °C), no exact concentration estimation could be performed..
- Mortality:
- No mortality was observed when 12 rats were exposed for 7 hours to an atmosphere that had been saturated at 20°C with the volatile parts of the compound.
- Clinical signs:
- other: No clinical signs of toxicity were observed.
- Body weight:
- no data
- Gross pathology:
- No abnormal findings were reported.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- No death were observed during a 7 h-inhalation exposure of rats to a saturated atmosphere of the test item at room temperature.
- Executive summary:
In an acute inhalation toxicity study, one group of 12 rats (6/sex) was exposed for 7 h to a saturated atmosphere of D-Panthenol at 20°C. Animals then were observed for 14 days. No mortality occurred. No clinical signs of toxicity. were observed. No gross pathological findings were reported.
