- Test Groups
The acute oral toxicity of Reaktiv-Gelb F-66 923 FW was tested only at a dose level of 2000 mg/kg body weight.
Five male and five female rats received the test compound as a 20% solution, the application volume being 10 ml/kg bodyweight.
If no compound-related mortality is produced in this limit test according to the guidelines no full study has to be carried out.
Preparation of the test substance
Reaktiv-Gelb F-66 923 FW was dissolved in the stated concentration in deionised water and distributed homogeneously by means of a magnetic stirrer.
Stability and homogeneity of the test substance was determined by analytical methods.
Test procedure
The prepared test substance was administered by gavage to fasted animals at the stated dosage. The observation period following treatment lasted for 14 days. Symptoms were recorded twice every day (in the morning and in the afternoon), on weekends and holidays only once. During this time the animals were weighed weekly. At the end of the observation period the animals were killed by carbon dioxide asphyxiation, dissected and examined for macroscopically visible changes.

- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Acute oral toxicity testing of Reaktiv-Gelb F-66 923 FW in the Wistar rat yielded a median lethal dose above 2000 mg/kg b.w. in both male and female animals.
- Executive summary:
Study conducted to EU test guidance 84/449/EEC part B1 and OECD test guideline 401 in compliance with GLP.
Acute oral toxicity testing of Reaktiv-Gelb F-66 923 FW in the Wistar rat yielded a median lethal dose above 2000 mg/kg b.w. in both male and female animals.
After application of 2000 mg/kg b.w. no deaths occurred.
Clinical signs were observed after application of 2000 mg/kg b.w., consisting of squatting posture and stilted gait. The feces of three animals were mucous and discoloured yellow.
From the first day p.a. up to the end of the study the animals were free of symptoms .
Development of body weight was not impaired.
The animals killed at the end of the observation period showed no macroscopically visible changes.
The substance is not considered harmful.
