Description of key information
Gene mutation in vitro:
Ames test:
Based on the prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Benzenesulfonic acid, 2,2'-(1,4-phenylenebis(carbonylimino (2-(acetylamino)-4,1-phenylene)-2,1-diazenediyl))bis(5-(2-(4-sulfophenyl)diazenyl)-, sodium salt (1:4). The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with S9 metabolic activation system. Benzenesulfonic acid, 2,2'-(1,4-phenylenebis(carbonylimino(2-(acetylamino)-4,1-phenylene) -2,1- diazenediyl)) bis(5-(2-(4-sulfophenyl)diazenyl)-, sodium salt (1:4) 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 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 be not toxic as per the criteria mentioned in CLP regulation.

Additional information
Gene mutation in vitro:
Prediction model based estimation for the target chemical and data from read across chemicals have been reviewed to determine the mutagenic nature of Benzenesulfonic acid, 2,2'-(1,4-phenylenebis(carbonylimino (2-(acetylamino)-4,1-phenylene)-2,1-diazenediyl)) bis(5-(2-(4- sulfophenyl)diazenyl)-, sodium salt (1:4). The studies are as mentioned below:
Based on the prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Benzenesulfonic acid, 2,2'-(1,4-phenylenebis(carbonylimino (2-(acetylamino)-4,1-phenylene)-2,1-diazenediyl)) bis(5-(2-(4-sulfophenyl)diazenyl)-, sodium salt (1:4). The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with S9 metabolic activation system. Benzenesulfonic acid, 2,2'-(1,4-phenylenebis(carbonylimino(2-(acetylamino)-4,1-phenylene) -2,1- diazenediyl)) bis(5-(2-(4-sulfophenyl)diazenyl)-, sodium salt (1:4) 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 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 prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, chromosomal aberration was predicted for Tetrasodium 2,2'-[1,4-phenylenebis [carbonylimino [2-acetamido-4,1-phenylene]azo]]bis [5-[ (4- sulphonatophenyl)azo] benzenesulphonate]. The study assumed the use of Chinese hamster ovary (CHO) cell line with and without S9 metabolic activation system. Tetrasodium 2,2'-[1,4-phenylenebis[carbonylimino[2-acetamido-4,1-phenylene]azo]]bis[5-[(4-sulphonatophenyl)azo] benzenesulphonate] acid was predicted to not induce chromosomal aberrations in Chinese hamster ovary (CHO) cell line 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.
The above mentioned predicted data is further supportecd by the data from read across chemicals as mentioned below:
In a study by Seifried et al (Chem. Res. Toxicol, 2006), Ames mutagenicity test was conducted for chemical 60 -70% structurally and functionally similar read across chemica; C.I Brilliant black BN ( food black 1; RA CAS no 2519 -30 -4) to evaluate its genetoxic effects when exposed to Salmonella typhimurium strains TA98, TA100, TA1535, TA1537, and TA1538 with dose concentration of 100-10000 µg/plate in plate incorporation hamster reductive assay. Based on the preliminary study conducted, the test compound was used at a five dose level from 100- 10000 µg/plate. C.I Brilliant black BN ( food black 1) did not induce gene mutation in the Salmonella typhimurium TA98, TA100, TA1535, TA1537, and TA1538 both in the presence and absence of S9 activation system and hence it is not likely to be a gene mutant.
Salmonella/microsome mammalian assay was performed by Przybojewska et al (Toxicology letters, 1986) to determine the mutagenic nature of 50 -60% structurally and functionally similar read across chemical Direct Red 81 (RA CAS no 2610 -11 -9). The study was performed using Salmonella typhimurium strains TA 1535, TA 1537, TA 1538, TA 98 and TA 100 in the presence and absence of S9 metabolic activation system. The test chemical was dissolved in Aqua distilled and used at dose levels of 0, 10, 100, 500 or 1000µg/plate. The doses for the main study were decided on the basis of preliminary dose range finding study. The plates were incubated for 48 hrs at 37˚C. An investigated compound was judged to have induced a positive response when a dose-related increase in the number of revertants was observed and the number of revertants exceeded the negative control values by at least 2-foId in at least two successive concentrations of the test chemical. Direct Red 81 did not induce gene mutation in Salmonella typhimurium strains TA 1535, TA 1537, TA 1538, TA 98 and TA 100 in the presence and absence of S9 metabolic activation system and hence it is not likely to classify as a gene mutant.
Based on the data available for the target chemical and its read across, Benzenesulfonic acid, 2,2'-(1,4-phenylenebis (carbonylimino (2-(acetylamino)-4,1-phenylene)-2,1-diazenediyl)) bis(5-(2-(4- sulfophenyl)diazenyl)-, sodium salt (1:4) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant as per the criteria mentioned in CLP regulation.
Justification for classification or non-classification
Based on the data available for the target chemical and its read across, Benzenesulfonic acid, 2,2'-(1,4-phenylenebis (carbonylimino (2-(acetylamino)- 4,1-phenylene)-2,1-diazenediyl)) bis(5-(2-(4- sulfophenyl)diazenyl)-, sodium salt (1:4) (CAS no 70210 -30 -9) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant as per the criteria mentioned in CLP regulation.
