Acute Oral Toxicity:

Acute oral toxicity dose was predicted based on OECD QSAR toolbox for target substance3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)was estimated to be 4566 mg/kg bw andfor differentstudies available on the closely related read across substance Niobium pentoxide (1313-96-8) was considered to be 4000 mg/kg bw for mouse and Dibismuth trisulphide (1345-07-9) was considered to be 5000 mg/kg bw for rats. All these studies concluded that the LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation,3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)can be classified as category V of acute oral toxicity.

Acute Inhalation Toxicity:

3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt has very low vapor pressure (4.49E-018 Pa), so the potential for the generation of inhalable vapours is very low. Also the normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be highly unlikely and therefore this end point was considered for waiver.

Acute Dermal Toxicity:

Acute dermal toxicity dose was predicted based on OECD QSAR toolbox for target substance substance3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)was estimated to be 14289.59 mg/kg bw for rabbits andfor differentstudies available on the structurally similar read across substance 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one (18472-87-2) was considered to be >2000 mg/kg bw for rats and for the closely related read across substance 2,2',6,6',-tetrabromo-4,4'-isopropylidenediphenol (79-94-7) was considered to be >2000 mg/kg bw for rabbits. All these studies concluded that the LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation,3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)can be classified as category V of acute dermal toxicity.

Acute Oral Toxicity:

In different studies,3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)has been investigated for acute oral toxicity to a greater or lesser extent. Often the studies are based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats for3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)along with the study available on the closely related read across substance Niobium pentoxide (1313-96-8) and Dibismuth trisulphide (1345-07-9). The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies. The studies are summarized as below –

In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9). The LD50 was estimated to be 4566 mg/kg bw when female Wistar rats were exposed with 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9)orally.

The above study was further supported by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) for the closely related read across substance Niobium pentoxide (1313-96-8). Acute oral toxicity study was done in mouse usingNiobium pentoxide(1313-96-8).No mortality was observed at dose 4000mg/kg bw. Clinical signs like Behavioral,muscle contraction or spasticity liver (hepatitis i.e. hepatocellular necrosis), in lungs, thorax, or respiration: acute pulmonary edema was observed in treated mouse. Hence, LD50was considered to be>4000mg/kgbody weight. When mouse was treated with Niobium pentoxide(1313-96-8)orally.

This is further supported by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) for the closely related read across substance Dibismuth trisulphide (1345-07-9). Acute oral toxicity study was done in rat using Dibismuth trisulphide (1345-07-9). 50% mortality was observed at dose 5000mg/kg bw. Hence, LD50was considered to be 5000 mg/kg body weight, when rats were treated with Dibismuth trisulphide (1345-07-9) orally.

Thus, based on the above studies on 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) and it’s closely related read across substances, it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) can be classified as category V of acute oral toxicity.

Acute Inhalation Toxicity:

3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt has very low vapor pressure (4.49E-018 Pa), so the potential for the generation of inhalable vapours is very low. Also the normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be highly unlikely and therefore this end point was considered for waiver.

Acute Dermal Toxicity:

In different studies, 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) has been investigated for acute dermal toxicity to a greater or lesser extent. Often the studies are based on in vivo experiments and estimated data in rodents, i.e. most commonly in rabbits for 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) along with the study available on structurally similar read across substance 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one (18472-87-2) and the closely related read across substance 2,2',6,6',-tetrabromo-4,4'-isopropylidenediphenol (79-94-7).The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies. The studies are summarized as below –

In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute dermal toxicity was estimated for 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9).TheLD50 was estimated to be 14289.59 mg/kg bw,when male and female New Zealand White rabbits were exposed occlusively 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) by dermal application for 24 hours.

The above study was further supported by Sustainability Support Services (Europe) AB (study number:18810, 2016-10-19) for structurally similar read across substance 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one (18472-87-2). The study now reported was designed and conducted to determine the acute dermal toxicity profile of 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3- oxoxanthen-9-yl)benzoic acid in Sprague Dawley rats. 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 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid supplied by Sustainability Support Services (Europe) AB, when administered to male and female Sprague Dawley rats was found to be greater than 2000 mg/kg body weight. Thus by considering the CLP criteria for acute toxicity rating for the chemicals, it infers that 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabro mo-6-hyd roxy-3-oxoxanthen-9-yl)benzoic acid does not exhibits acute toxicity by the dermal route.

This is further supported by U.S. National Library of Medicine(HSDB (Hazardous Substances Data Bank); US national Library of Medicine,2017) and IFA GESTIS (Gestis Substance Database ,2017) for closely related read across substance 2,2',6,6',-tetrabromo-4,4'-isopropylidenediphenol (79-94-7). In acute dermal toxicity study,groups of 5 male and female rabbits were treated with2,2',6,6',-tetrabromo-4,4'-isopropylidenediphenol(79-94-7)in the concentration of 2000 mg/kg bw by dermal application.No mortality was observed in treated rabbits at dose 2000 mg/kg bw.Therefore, LD50 value was considered to be >2000 mg/kg bw,when rabbits were occlusively treated with 2,2',6,6',-tetrabromo-4,4'-isopropylidenediphenol (79-94-7) by dermal application for 24 hours following 14 days of observation period.

Thus, based on the above studies on 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) and it’s structurally similar and closely related read across substances, it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) can be classified as category V of acute dermal toxicity.

Based on the above studies and prediction on 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) and it’s closely related and structurally similar read across substances, it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt (84473-86-9) can be classified as category V for acute oral and dermal toxicity. For Acute inhalation toxicity wavier was added so, not possible to classify.
