Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Remarks:
- No detail on the test item was provided (purity, solubility and stability), no details on preparation of test item was provided, the volume of gavage was not given. The non GLP-compliant study did not follow modern standard but give information on the range of the LD50 value.
- Conclusions:
- Under the experimental conditions of this study, the test item induced mortality of all animals at the high dose level. However, in male male, no mortaility was found at 1250 mg/kg bw and 3 females were found dead at this dose level. The LD50 value was below the value of 2500 mg/kg bw and for female was between 625 mg/kg bw and 1250 mg/kg bw. Hence, the test item was classified as Acute Oral Hazard Category 4 according CLP criteria.
- Executive summary:
This non-GLP compliant study was performed in order to assess the potential Acute Oral Toxicity of the test item HC Yellow 2 in rats. No detail on the test item was provided (purity, solubility and stability), no details on preparation of test item was provided, the volume of gavage was not given. The non GLP-compliant study did not follow modern standard but give information on the range of the LD50 value in acute oral toxicity test on rats.
A 10% suspension of the test substance in 3% acacia was administered once via oral gavage to groups of 5 male and 5 female rats at the dose levels 625, 1250, and 2500 mg/kg bw. At the low dose no mortalities were observed, at the mid dose no deaths were seen in the males while 3 of 5 females died within 8 h after dosing. At the high dose all animals died.
Under the experimental conditions of this study, the test item induced mortality of all animals at the high dose level. However, in male, no mortaility was found at 1250 mg/kg bw and 3 females were found dead at this dose level. The LD50 value was below the value of 2500 mg/kg bw and for female was between 625 mg/kg bw and 1250 mg/kg bw. Hence, the test item was classified as Acute Oral Hazard Category 4 according to CLP criteria.
