Results and discussion
- Preliminary study:
- 1 animal/sex was tested at 5000 mg/kg bw. The female was found dead one day after dosing. Signs of systemic toxicity noted in the female were hunched posture, lethargy, decreased respiratory rate, ptosis and ataxia. Based on this information, a dose level of 5000 mg/kg bw was selected for the main study.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this test, the acute oral median lethal dose (LD50) of ITC 288/S was found to be greater than 5000 mg/kg body weight in the Sprague-dawley strain rat. Therefore no classification is required according to the EU legislation (CLP regulation (1272/2008) and Directive 67/548/EEC).
- Executive summary:
In an acute oral toxicity study (Tuffnell PP, 1992) a group of ten fasted animals (five males and five females) was given a single oral dose of the test material, as a solution in distilled water at dose level of 5000 mg/kg bodyweight. The animals were observed for 14 days after the day of dosing and were then killed for gross pathological examination. There were no deaths. No signs of systemic toxicity were noted during the study. Moreover, all animals showed expected gain in bodyweight during the study. No abnormalities were noted at necropsy. Under the conditions of this test, the LD50 combined of ITC 288/S was found to be greater than 5000 mg/kg body weight. Based on the present results in males and females, ITC 288/S is not classified according to the EU legislation (CLP regulation (1272/2008) and Directive 67/548/EEC).
This acute oral study is classified as acceptable. It satifies the guideline requirement for an acute oral study in the rats.
