- Exp. duration:
- 4 h
- Mortality:
- There were no deaths following a single inhalation dose of the test substance at 12200 mg/m3 air.
- Clinical signs:
- other: Increased motor activity and slight erythema were observed during the 4 hour exposure period. After 4 hours exposure, 1 rat exhibited salivation. After 24 hours and after 14 days all animals appeared normal.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LC50 was considered to be >12,200 mg/m3 air. The test substance would not be considered a highly toxic material by the inhalation route of administration.
- Executive summary:
Five male and 5 female rats of the Spartan strain was used in this test. The group of 10 rats was placed in a sealed 59.1 liter glass chamber and exposed for 4 hours to a dynamic atmosphere containing the dust of 12200 mg/m3 test substance.
The LC50 was considered to be >12,200 mg/m3 air. The test substance would not be considered a highly toxic material by the inhalation route of administration.
