Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate]

Endpoint summary

Description of key information

Acute oral toxicity:

The acute oral LD50 (Cut-off value) of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6 -tetrachlorobenzoate] (CAS No. 15876-58-1) was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered via oral route in Sprague Dawley rats considered to be "Not classified" as per the CLP regulation.

Acute inhalation toxicity:

The study need not to be conducted because exposure of human via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size – (exposure considerations)

Acute dermal toxicity:

It was concluded that the acute dermal median lethal dose (LD50) of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered to male and female Sprague Dawley rats was found to be greater than 2000 mg/kg body weight. Thus, according to CLP criteria for acute toxicity rating for the chemicals, it infers that Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) does not classify as an acute dermal toxicant.

Conclusions:

Under the condition of the study, the acute oral LD50 (Cut-off value) of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6 -tetrachlorobenzoate] (CAS No. 15876-58-1) was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered via oral route in Sprague Dawley rats considered to be "Not classified" as per the CLP regulation

Executive summary:

The study now reported was designed and conducted to determine the acute oral toxicity profile of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) in Sprague Dawley rats.

Initially, three 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 resulted in test item coloured feaces and test item coloured urine with onset on day 1 after the dosing and no mortality at 24 hours after the dosing. As no mortality was observed at 24 hours after the dosing, three 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 resulted in test item coloured feaces and test item coloured urine with onset on day 1 after the dosing and no mortality after the dosing.

No mortality was observed at 300 mg/kg dose group, hence additional three 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 test item coloured feaces and test item coloured urine with onset at 6 hours after the dosing and no mortality after the dosing. As no mortality was observed at 24 hours after the dosing, 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 resulted in test item coloured feaces and test item coloured urine with onset at 6 hours after the dosing and no 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 Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1)was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered via oral route in Sprague Dawley rats considered to be"Not classified" as per the CLP regulation.

The test item was applied to shorn skin of 5 male and 5 female animals at 2000 mg/kg body weight. Administration of the test item at 2000 mg/kg did not result in any skin reaction at the site of application during the study period of 14 days. Administration of the test item did not result in any signs of toxicity and mortality during the study period of 14 days.   

Animals exhibited normal body weight gain through the study period of 14 days.

Gross pathological examination did not reveal any abnormalities attributable to the treatment. 

It was concluded that the acute dermal median lethal dose (LD₅₀) of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered to male and female Sprague Dawley rats was found to be greater than 2000 mg/kg body weight. Thus, according to CLP criteria for acute toxicity rating for the chemicals, it infers that Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) does not classify as an acute dermal toxicant.

Additional information

Acute oral toxicity:

In a studies, Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] has been investigated for acute oral toxicity to a greater or lesser extent. Study based on in vivo experiments in rodents, i.e. most commonly in rats for Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] and summarized below.

In a experimental study conducted by Sustainability Support Services (Europe) AB, Sweden (2017), the study now reported was designed and conducted to determine the acute oral toxicity profile of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) in Sprague Dawley rats.

Initially, three 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 resulted in test item coloured feaces and test item coloured urine with onset on day 1 after the dosing and no mortality at 24 hours after the dosing. As no mortality was observed at 24 hours after the dosing, three 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 resulted in test item coloured feaces and test item coloured urine with onset on day 1 after the dosing and no mortality after the dosing.

No mortality was observed at 300 mg/kg dose group, hence additional three 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 test item coloured feaces and test item coloured urine with onset at 6 hours after the dosing and no mortality after the dosing. As no mortality was observed at 24 hours after the dosing, 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 resulted in test item coloured feaces and test item coloured urine with onset at 6 hours after the dosing and no 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 Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1)was 5000 mg/kg body weight. Thus, it was concluded that the acute toxicity study of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1), when administered via oral route in Sprague Dawley rats considered to be"Not classified" as per the CLP regulation.

Acute inhalation toxicity:

The study need not to be conducted because exposure of human via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size – (exposure considerations)

Acute dermal toxicity:

In a studies, Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] has been investigated for acute dermal toxicity to a greater or lesser extent. Study based on in vivo experiments in rodents, i.e. most commonly in rats for Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] and summarized below.

In a experimental study conducted by Sustainability Support Services (Europe) AB, Sweden (2017), Sprague Dawley male and female rats were treated with Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] as per OECD 402. The test item was applied to shorn skin of 5 male and 5 female animals at 2000 mg/kg body weight. Administration of the test item at 2000 mg/kg did not result in any skin reaction at the site of application during the study period of 14 days. Administration of the test item did not result in any signs of toxicity and mortality during the study period of 14 days.  Animals exhibited normal body weight gain through the study period of 14 days. Gross pathological examination did not reveal any abnormalities attributable to the treatment.

It was concluded that the acute dermal median lethal dose (LD50) of Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] (CAS No. 15876-58-1) when administered to male and female Sprague Dawley rats was found to be greater than 2000 mg/kg body weight.

Thus, based on the above study on Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate], it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] can be classified as category V of acute dermal toxicity.

Justification for classification or non-classification

Based on the above studies and predictions on Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] , it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Di aluminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] can be considered as "Not classified" for acute oral and dermal toxicity.
