Details on test system and experimental conditions:
The test was conducted in duplicate by the preincubation method. Into a test tube was poured 0.1 mL of test substance solution, 0.5 mL of 0.1 M sodium phosphate buffer solution (pH 7.4) and 0.1 mL of bacterial suspension were added, and the mixture was shaken for 20 min at 37 degrees C. When S9 was present, 0.5 mL of S9 mix was added instead of the 0.1 M sodium phosphate buffer solution. Following preincubation, 2 mL of top agar was admixed to the test tube and the contents tereof were layered on a minimum glucose agar plate medium. Once the layered top agar had solidified, the bacteria were cultured for 48 hours at 37 degrees C. The development of bacterial colonies was observed with a steromicroscope. After checking for the presence of antibackterial properties due to the test substance, the number of reverse mutation colonies on the plate was counted with an automatic colony counter. In the preliminaty tests, one plate was employed at each concentration. In the main test, three plates were employed at each concentration and the test was conducted twice to confirm reproducibility. Further, a negative control substance (solvent) and a positive control substance for each bacteria strain were employed in place of the test substance solution to provide control groups that were handled in the same manner as the test substance groups.
Evaluation criteria:
when the number of reverse mutation colonies (average value) accompanying an increase in test substance concentration increased to twice or more that of the negative control value, and that increase was found to be reproducible, the test substance was judged to be positive. All other cases were judged to be negative.
Statistics:
Statistical menthods were not employed to judge the test results.

Gene toxicity in vitro:

Prediction model based estimation and the data from read across (CAS no 8004 -92 -0) is used to predict the mutagenic nature of the test compound CAS no 84864 -68 -6. The summary is as below:

Gene mutation was predicted using SSS QSAR prediction model, 2016. The study used Salmonella typhimurium TA1535 strain and with S9 metabolic activation system. The test material sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate is not mutagenic in vitro in Salmonella typhimurium strain TA 1535 with S9 metabolic activation system. In another study, Salmonella typhimurium TA102 strain was used without S9 metabolic activation system. The test material sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate is not mutagenic in vitro in Salmonella typhimurium strain TA 102 without S9 metabolic activation system. In yet another study, Chinese hamster cell line was used without S9 metabolic activation system. In all the studies conducted the test material sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate is not mutagenic in vitro.

Spot test was performed by Blevins et al (1982) to determine the mutagenic potential of the test compound D & C yellow no 10 (RA 8004 -92 -0). Following cosmetic ingredient treatment of the individual Salmonella strains, the strains were plated on Vogel Bonner Medium E minimal agar plates and incubated for 48 hr at 37°C. The toxicity of the cosmetic ingredient was evidenced by either a clearing of the bacterial lawns (the reduction of colony counts below the range of spontaneous revertants) or the appearance of pinpoint his colonies.Prior to and following chemical cosmetic ingredient exposure, plate counts were done to determine percentage survival of colony-forming units per complete growth medium plates.The cosmetic ingredient was considered mutagenic if there was a significant increase (a reproducible dose related increase in the number of revertant colonies) in the number of colonies on the plate compared with both the nontreated and cosmetic ingredient treated plates. Colonies with a diameter of more than 0.2 mm were counted. The test compoundD & C yellow no 10 did not induce mutation in theSalmonella typhimuriumLT2 - hisTA98, hisTA100, hisTA1535, hisTA1537, and hisTA1538 in the spot test performed and hence is negative for mutation in vitro.

OECD 471 guideline was followed (SCCS, 2004) to determine the mutagenic nature of the test compound Acid yellow 3 (RA CAS no 8004 -92 -0). The chemical was tested at 6 concentrations from 33-5000 μg/plates. In a preliminary experiment with 8 doses, no toxicity was observed, although some toxicity was observed in the first experiment at the high doses. There was no increase in the number of revertants in all strains and in the two experiments in all conditions. The test compound D & C yellow no 10 is not mutagenic in the S. typhimurium TA 98, TA 100, TA 1535, TA 1537; E. coli WP2 uvr A in the mutagenic study performed.

OECD 476 guideline was used (SCCS, 2004) to determine the mutagenic potential of the test compound D & C yellow no 10 (RA CAS no 8004 -92 -0) to mouse lymphoma L5178Y (Thymidine kinase locus) with and without S9 activation system. The test material was tested at concentration of 118-3800 μg/ml. No toxicity was observed until the dose of 3800 μg/ml. The test item did not induce a significant increase of the number of mutant colonies (small and large) in the presence and in the absence of a metabolic activation system in the replicated cultures. The test compound D & C yellow no 10 is not mutagenic/clastogenic to mouse lymphoma L5178Y (Thymidine kinase locus) with and without S9 activation system.
