Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 401 (Acute Oral Toxicity)
- Deviations:
- no
- Principles of method if other than guideline:
- The study was performed before GLP- and OECD-testing guidelines were available and in force.
A group of approximately 70 albino male and female rats, fasted for twenty-four hours were employed to establish an LD50 range for each product under test. Young adult rats which had not been used for previous test purposes were assigned to various dose levels at random. Both sexes were equally distributed. Body weight of the rats were 200-300 grams at the beginning of the study. Animals on the same dosage level were then placed in a common cage with free access to food and water. The animals were observed daily for a two week period.
No postmortem, or histopathology examinations were performed in this particular study. - GLP compliance:
- no
- Remarks:

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute oral toxicity on Albino rats was determined to be 12300 mg/kg for males and 10800 mg/kg for females.
- Executive summary:
A study was carried out equivalent or similar to EU Method B.1 and OECD Guideline 401 (Acute Oral Toxicity). 6 groups of 10 rats (5 male, 5 female) were treated by gavage with doses from 2000 up to 16000 mg/kg.Males and females dosed at 2.0 g/kg and 4.0 g/kg exhibited moderate diarrhea for 2-3 days following intubation. Lethargy and moderate to severe diarrhea were noted at 6.4 g/kg (only males tested) and 8.0 g/kg (both sexes). Rapid erratic respiration, lethargy, severe diarrhea, ruffled and unkempt coats were evident at the 10.0 g/kg and 12.6 g/kg dosage levels in both sexes. Death animals were observed at dose levels of 6400 mg/kg and above; for details refer to the above mentioned table. At 16000 mg/kg, the animals succumbed within 30 minutes after forced feeding. The LD50 was determined to be 12300 mg/kg for females and 10800 mg/kg for males.
