Additional information

Additional information from genetic toxicity in vitro:

Gene mutation in vitro:

Gene mutation was predicted using SSS QSAR prediction model, 2016. The study used Salmonella typhimurium TA97 strain with and without S9 metabolic activation system. The test material 4-amino-5-hydroxynaphthalene-1,7-disulphonic acid (CAS no 130 -23 -4) is not mutagenic in vitro in Salmonella typhimurium strain without S9 metabolic activation system.

Based on the QSAR prediction done using the Danish (Q)SAR Database (2016), the genetic toxicity was estimated to be negative duringAmes test in S. typhimurium. Thus it can be concluded that the substance 4-amino-5-hydroxynaphthalene-1,7-disulphonic acid (CAS no 130 -23 -4) is non genotoxic.

Based on the QSAR prediction done using the Danish (Q)SAR Database (2016), the genetic toxicity was estimated to be negative during Chromosome Aberrations in Chinese Hamster Ovary (CHO) Cells. Thus it can be concluded that the substance 4-amino-5-hydroxynaphthalene-1,7-disulphonic acid is non genotoxic.

Gene mutation toxicity study was performed to evaluate the mutagenic nature of the test compound 3-amino-4-hydroxybenzene sulphonic acid (RA CAS no 98 -37 -3). Genetic toxicity in vitro for 3-amino-4-hydroxybenzene sulphonic acid in S. typhimurium TA 1535 is found to be negative at dose concentration of 0 - 2000 ug/Plate with and without metabolic activation and hence is likely to be not classified for gene mutation in vitro..

(Mortelmans et al, 2000).

Genetic toxicity in vitro study was performed for the test chemical 3-amino-4-hydroxybenzenesulphonic acid (RA CAS no 98 -37 -3) using S. typhimurium TA 98. The test compound was found to be negative at dose concentration of 0 - 2000 ug/plate with and without metabolic activation and hence is likely to be not classified for gene mutation toxicity in vitro (Mortelmans et al, 2000).

The test chemical 3-amino-4-hydroxybenzenesulphonic acid (RA CAS no 98 -37 -3) was studied to for its ability to induce mutations in strains of Salmonella typhimurium (Zeiger et al, 1988).The test compound was tested at concentration of 0, 33, 100, 333, 1000 or 2000 µg/plate using Salmonella typhimurium TA100, TA1535, TA97 and TA98 in the presence and absence of rat and hamster liver S9 metabolic activation system. Preincubation assay was performed. The test compound is not mutagenic to the Salmonella typhimurium TA100, TA1535, TA97 and TA98 in the presence and absence of rat and hamster liver S9 metabolic activation system.

Bacterial reverse mutation assay was performed (BG Chemie, 2000) to evaluate the mutagenic nature of the test compound 6-Amino-4-hydroxy-2-naphthalene-sulfonic acid (RA CAS no 90 -51 -7). Standard plate incorporation assay was performed at concentrations ranging from 8-5000 µg/plate, with and without metabolic activation system. At concentrations above 200µg/plate, the test chemical had a weak strain specific bacteriotoxic effect. No concentration dependent biologically relevant increase in the number of revertant count was observed

The test compound 6-Amino-4-hydroxy-2-naphthalene-sulfonic acid is not mutagenic in the bacterial reverse gene mutation assay performed using Salmonella typhimurium TA98, TA100, TA1535, TA1537.

Based on the information observed for the test chemical using prediction model and data from its various read across, it is summarized that

4-amino-5-hydroxynaphthalene-1,7-disulphonic acid (CAS no 130 -23 -4) is not likely to exhibit genetic toxicity. Thus, the chemical is not classified as a genetic toxicant.


Justification for selection of genetic toxicity endpoint
The data is obtained using Prediction model.

Justification for classification or non-classification

Based on the weight of evidence and also as per the CLP criteria, 4-amino-5-hydroxynaphthalene-1,7-disulphonic acid (CAS no 130 -23 -4) is not mutagenic in vitro.
