Registration Dossier

Prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate]. The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without S9 metabolic activation system. Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] was predicted to not induce gene mutation in Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 in the presence and absence of S9 metabolic activation system and hence, according to the prediction made, it is not likely to classify as a gene mutant in vitro. Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.

Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate]. The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without S9 metabolic activation system. Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] was predicted to not induce gene mutation in Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 in the presence and absence of S9 metabolic activation system and hence, according to the prediction made, it is not likely to classify as a gene mutant in vitro. Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.

Salmonella/ mammalian-microsome test was performed by Jeanne M. Et al.(Mutation Research, 1979) to evaluate the mutagenic nature of the read across chemicals D&C Red No. 27 (RA CAS no13473-26-2; IUPAC name: 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one . Salmonella/ mammalian-microsome test was performed to evaluate the mutagenic nature of the test compound D and C Red no. 27 (13473 -26 -2). The 2 ml of liquid top agar was cooled to 45°C and 0.1 ml of a broth culture of microorganism and test substance in volumes of ≤ 0.4 ml of DMSO was added prior to placing on minimal agar plates. After 48 h incubation at 37°C, the colonies which reverted to the prototroph were counted and compared to counts on the control plate (containing no test substance) to demonstrate mutagenicity or toxicity. The test material was exposed in the presence and absence of metabolic activation.Materials which caused a 2-fold increase of revertants, as compared to the number of spontaneous revertants on the control plates, was denoted as mutagens. Those which reduced the number of revertants were considered inhibitory. The test compound D and C Red no. 27 failed to induce mutation in Salmonella typhimurium TA98, TA1537, TA100, TA1535) and hence is negative for gene mutation in vitro

Brown et al (Mutation Research, 1979) performed Salmonella/mammalian microsome assay evaluate the mutagenic nature of D and C Red No. 27/ Phloxine B (RA CAS no 18472 -87 -2; IUPAC name: 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one). The dye was dissolved in dimethylsulfoxide and up to 0.2 ml was introduced into 2.5 ml of the tempered top agar together with 0.1 ml Salmonella typhimuriumbroth suspension and 0.25 ml Aroclor 1254 induced rat liver S9. The mixtures was plated on 20 ml of Vogel-Bonner E bottom agar in the usual fashion and incubated for 3 days at 35°. Each agent was tested with all 5 basic tester strains (TA1535, TA100, TA1537, TA1538, TA98) with and without microsomal activation at concentrations of 0, 10, 50 or 100 µg/plate. Phloxine B did not show any mutagenic activity in the Salmonella typhimurium tester strains TA98, TA100, TA1535, TA1537 and TA1538 in the presence and absence of S9 metabolic activation system and hence is not likely to classify as a gene mutant in vitro.

Gene mutation in vivo:

Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate].. The study assumed the use of male and female rat. Dialuminium tris[2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)-3,4,5,6-tetrachlorobenzoate] was predicted to not induce gene mutation in male and female rat and hence, according to the prediction made, it is not likely to classify as a gene mutant in vivo.Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.

In the in vivo micronucleus test performed by Hayashi et al (Food and Chemical Toxicology, 1988) for structurally similar read across chemical Acid Red 92 (Phloxine; RA CAS no 6441 -77 -6; IUPAC name: Dipotassium 3,6-dichloro-2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)benzoate). The chemical was investigated in male ddY mice for mutagenicity. The test chemical was administered by intraperitoneal injection once (at doses 0, 30, 60 or 120 mg/kg) or 4 times 24 hours apart (at a dose of 60 mg/kg/injection). Femoral marrow cells were flushed out with foetal bovine serum and smeared on clean glass slides. Cells were fixed with methanol for 5 min, and stained with Acridine Orange for the pilot experiment and with Giemsa for the full-scale test. One thousand polychromatic erythrocytes per mouse were scored using a light microscope. After treatment, the number of micronucleated polychromatic erythrocytes (MNPCEs) was recorded and the proportion of polychromatic erythrocytes (PCEs) among the total erythrocytes was evaluated. Based on the results, no mutagenic effects could be detected. Therefore, Acid Red 92 is considered to be non-mutagenic when male ddY mice were exposed to the test chemical.

Genetic toxicity in vivo study (SCCS, 2004) was performed for another structurally similar read across chemical Acid Red 92 (RA CAS no 18472 -87 -2; IUPAC name: 2',4',5',7'-tetrabromo-4,5,6,7-tetrachloro-3',6'-dihydroxy-3H-spiro[2-benzofuran-1,9'-xanthen]-3-one) using male and female NMRI mice. Acid red 92 was injected intraperitoneally in mice and the number of micronucleus formed in the polychromatic erythrocytes was noted. The positive control (Cyclophosphamide) induced 2.030 % of MN in PCEs (0.08 % in the control animals: significance p 0.0040). In the treated animals with 100 mg/kg a percentage of MN 0.150 (24h) and 0.110 (48h) was observed: these values, although higher than the control, had a p > 0.34. A reduction of PCE was observed, thus indicating a cytotoxic effect of the test item in the bone marrow cells. Acid Red 92 did not induce micronucleus in the bone maroow polychromatic erthrocytes and hence it is non mutagenic in the In vivo Mammalian Erythrocyte Micronucleus Test performed

Based on the data available for the target chemical and its read across, 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 exhibit gene mutation in vitro and in vivo and hence does not classify for mutagenic effects as per the criteria mentioned in CLP regulation.

Thus based on the above annotation and CLP criteria , the test chemical Dialuminium tris(2-(2,4,5,7- tetrabromo-6-oxido-3-oxoxanthen-9-yl) 3,4,5,6- tetrachlorobenzoate) is considered to be non-mutagenic in vitro and in vivo.
