Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The LD50 values for acute toxicity (oral) in mice (ICL-ICR) of the test item were reported to be 1150 mg/kg bw (female) and 900 mg/kg bw (male).
- Executive summary:
The oral LD50 values of the substance in mice (ICL-ICR) were reported to be 900 (males) and 1150 (females) mg/kg body weight (Litchfield-Wilcoxon statistics).
Most of the deaths in male mice occured within 1h after administration, whereas those in treated female mice occured between 1 and 48h after administration. Thinning of the stomach and small intestinal walls, bleeding of the glandular portion of the stomach, and hypertrophy of the gallbladder were seen in the treated animals.
