Endpoint summary

Description of key information

Acute oral toxicity:

Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the acute oral toxicity of the test chemical Aluminum, 2-(1,3-dihydro-1,3-dioxo-2H-inden-2-ylidene)-1,2-dihydro-6,7-quinolinedisulfonate complexes (CAS no.: 94891-32-4). The studies are as mentioned below:

1. The acute oral toxicity study was designed and conducted for test chemical in Sprague Dawley rats. Initially, 3 female animals were treated at the dose level of 300 mg/kg body weight of the test item (Step - I). Administration of the test item at 300 mg/kg did not result in any signs of toxicity and mortality at 24 hours after the dosing. As no mortality was observed at 24 hours after the dosing, 3 female animals were added to the study and treated with the same dose of 300 mg/kg of the test item (Step - II). Administration of the test item at 300 mg/kg did not result in any signs of toxicity and mortality after the dosing. No mortality was observed at 300 mg/kg dose group, hence additional 3 female animals were treated with the higher dose of 2000 mg/kg of the test item (Step - I). Administration of the test item at 2000 mg/kg resulted in diarrhoea (blue colour stools) in all animals with onset at 2 hours and no mortality after the dosing. As no mortality were observed at 24 hours after the dosing, hence additional 3 female animals were treated with the higher dose of 2000 mg/kg of the test item (Step - II). Administration of the test item at 2000 mg/kg resulted in diarrhoea (blue colour stools) in all animals with onset at 2 hours and no mortality after the dosing. All animals from 300 mg/kg and 2000 mg/kg dose groups survived through the study period of 14 days. Staining of the stool is attributed to the blue colour of the test item. Gross pathological examination did not reveal any abnormalities in animals from 300 mg/kg and 2000 mg/kg dose groups. The acute oral LD50 (Cut-off value) of test chemical was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of test chemical, when administered via oral route in Sprague Dawley rats falls into the “Category Not classified” criteria of CLP.

Initially, 3 female animals were treated at the dose level of 300 mg/kg body weight of the test item (Step - I). Administration of the test item at 300 mg/kg did not result in any signs of toxicity and mortality at 24 hours after the dosing.

Administration of the test item at 300 mg/kg did not result in any signs of toxicity and mortality after the dosing. No mortality was observed at 300 mg/kg dose group, hence additional 3 female animals were treated with the higher dose of 2000 mg/kg of the test item (Step - I). Administration of the test item at 2000 mg/kg did not result in any signs of toxicity and mortality after the dosing. As no mortality were observed at 24 hours after the dosing, hence additional three female animals were treated with the higher dose of 2000 mg/kg of the test item (Step - II). Administration of the test item at 2000 mg/kg did not result in any signs of toxicity and mortality after the dosing. Gross pathological examination did not reveal any abnormalities in animals from 300 mg/kg and 2000 mg/kg dose groups. The acute oral LD50 (Cut-off value) of test chemical was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of test chemical, when administered via oral route in Sprague Dawley rats falls into the “Category Not classified” criteria of CLP.

Thus, based on the above summarised studies, Aluminum, 2-(1,3-dihydro-1,3-dioxo-2H-inden-2-ylidene)-1,2-dihydro-6,7-quinolinedisulfonate complexes (CAS no.: 94891-32-4) and it’s structurally similar read across substances, it can be concluded that LD50 value is >2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Aluminum, 2-(1,3-dihydro-1,3-dioxo-2H-inden-2-ylidene)-1,2-dihydro-6,7-quinolinedisulfonate complexes (CAS no.: 94891-32-4) cannot be classified for acute oral toxicity. Hence, Aluminum, 2-(1,3-dihydro-1,3-dioxo-2H-inden-2-ylidene)-1,2-dihydro-6,7-quinolinedisulfonate complexes is not toxic for acute oral toxicity.
