Applicant's summary and conclusion
- Interpretation of results:
- Category 3 based on GHS criteria
- Conclusions:
- The substance caused 100% mortality in dust concentrations of 2.15 and 5.20 mg/L air in male and female rats. The 4-h LC50 (inhalation) was determined between 0.51 and 2.15 mg/L air. Therefore, the substance is classified as Category 3 for acute inhalation toxicity.
