Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No animal died during the 14 day observation period following treatment.
- Clinical signs:
- other: There were no overt signs of toxicity noted in any test animal during the observation period.
- Gross pathology:
- No findings
- Other findings:
- Skin reactions:
Erythrema (scores 1 and 2) was noted on 10/10 animals, on Day 1. Erythrema was reversed in all animals by Day 2. No signs of Edema was noted on any animal during the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item is considered non-toxic in rabbits, at a dose of 2000 mg/kg bw by dermal application, based upon the absence of mortality and criteria set forth by FIFRA.
- Executive summary:
The test item was evaluated for its potential to produce systemic toxicity or death following topical application at a dose of 2000 mg/kg bw in male and female New Zealand White albino rabbits. Based on the absence of moratlity and the criteria of the study protocol, the test substance is defined as non-toxic via the dermal route. It should be noted that erythrema (score 1 and 2) were observed in 10/10 animaly at Day 1, which were fully reversible at Day 2.
