Applicant's summary and conclusion
- Interpretation of results:
- other: EU GHS criteria not met
- Conclusions:
- The study was performed according to the OECD TG401 without deviations and therefore considered to be of the highest quality (reliability Klimisch 1). The validity criteria of the test system are fulfilled. The test material did not induce mortality or treatment-related clinical signs. The test material was considered to be non-toxic under the conditions of the test.
- Executive summary:
A study was performed to assess the acute oral toxicity of the test material in the Sprague-Dawley CD strain rat. The method followed that in the OECD Guidelines for Testing of Chemicals No. 401 "Acute Oral Toxicity" (adopted 24 February 1987) and Method B1 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). Following a range-finding study, a group of ten fasted animals (five males and five females) was given a single oral dose of test material as a solution in distilled water at a dose level of 2000 mg/kg bodyweight. The animals were observed for fourteen days after the day of dosing and were then killed and subjected to gross pathological examination. There were no deaths. No signs of systemic toxicity were noted during the study. All animals showed an expected gain in bodyweight during the study. No abnormalities were noted at necropsy. The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight. No symbol and risk phrase are required according to EU labelling regulations.
