Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In a study according to OECD test guideline 423 (acute oral toxicity) under GLP, the LD50 (rat) of the test substance was determined to be > 2000 mg/kg bw.
- Executive summary:
The test substance was administered to a group of 6 female Sprague Dawley rats at the single dose of 300 mg/kg body weight and to a group of 6 female Sprague Dawley rats at the single dose of 2000 mg/kg body weight. The experimental protocol was established on the basis of the official method as defined in the O.E.C.D, guideline N° 423 dated December 17th, 2001. No mortality occurred during the study at 300 mg/kg or at 2000 mg/kg body weight. No clinical signs related to the administration of the test substance were observed. The body weight development of the animals remained normal throughout the study. The macroscopical examination of the animals at the end of the study did not reveal treatment-related changes. In conclusion, the LD50 of the test isubstance is higher than 2000 mg/kg body weight by oral route in the rat.
