Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LD50 of the test substance for acute oral toxicity to female and male rat was determined to be > 5000 mg/kg bw.
The substance is not classifiable according to CLP criteria - Executive summary:
An oral acute toxicity study with Acid Yellow 232 was performed at dose levels of 5000 and 3100 mg/kg bw in 5 male and 5 female rats per group.
At 5000 mg/kg bw, the following clinical signs were observed: impaired general condition, diarrhoea, and nausea. These clinical signs started directly after application, were of minor severity and lasted until Day 5.
One female rat at 5000 mg/kg bw died on Day 2.
The dose level of 3100 mg/kg bw were tolerated without any adverse effects.
Body weight development was not affected by test substance administration.
The acute oral LD50 was determined to be higher than 5000 mg/kg bw based on test material. This equals to higher than 3400 mg/kg bw based on active ingredient.
