Endpoint summary
Administrative data
Description of key information
acute oral toxicity, rat (M/f), gavage, > 8000 mg/kg bw
Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 8 000 mg/kg bw
Additional information
The analogue test item was tested for acute oral toxicity (Huntsman, 1980). Male and female rats were gavaged at different doses up to 8000 mg/kg bw. Under the experimental conditions the LD50 > 8000 mg/kg bw.
Based on the read across considerations the same results apply to Acid Black 164.
Justification for classification or non-classification
According to the CLP Regulation (EC n. 1272/2008), table 3.1.1, Acute toxicity hazard categories and acute toxicity estimates (ATE) defining the respective categories:
For Acute toxicity oral route:
Category 1: ATE <= 5 mg/kg bw
Category 2: 5 < ATE <= 50 mg/kg bw
Category 3: 50 < ATE <= 300 mg/kg bw
Category 4: 300 < ATE <= 2000 mg/kg bw
The LD50 of the test substance was determined to be 8000 mg/kg bw , which is outside the above criteria. Therefore, the test substance is not classified for Acute toxicity by oral exposure.
