Genetic toxicity in vitro
Description of key information
AMES assay
Experimental Study report of target substance Tridecanol (112-70-9) was observed by U. S. National Library of Medicine (CCRIS ,2018 ) to evaluate its mutagenic nature. Tridecanol was considered to be non mutagenic in Salmonella typhimurium TA100, TA1535, TA98, TA1537, Escherichia coli WP2 uvrA/ PKM101 by AMES test.
In vitro chromosomal abbreviation study
Test substance result was considered to be negative in Mammalian cell line,both in the presence and absence of metabolic activation.Hence the substance cannot be classified as gene mutant in vitro.
In Vitro Mammalian Cell Gene Mutation Test
In a reliable study, test chemical did not increase the gene mutation rate in Chinese hamster V79 cells in the presence or absence of metabolic activation at concentrations up to 20 ug/ml. It is concluded that the test substance is negative for mutagenicity in mammalian cells under the conditions of this test.

- Conclusions:
- Test chemical did not induce structural chromosomal aberrations in the absence or presence of an exogenous metabolic activation system in an in vitro mammalian chromosome aberration test in Chinese hamster lung(CHL)cells.
- Executive summary:
5. Structural chromosomal aberrations and polyploidy were not induced up to a maximum concentration of test chemical under conditions of continuous treatment, and short-term treatment with and without an exogenous metabolic activation system in Chinese hamster lung(CHL)cells. Hence the substance cannot be classified as genetox in vitro
6. In an in vitro chromosome aberration study, Chinese hamster lung fibroblasts (V79) were incubated with 0.6, 10.0 and 20.0 µg/ml of test material dissolved in ethanol for 4 hours, with and without metabolic activation. The test substance did not increase the incidence of chromosome aberrations in Chinese hamster V79 cells in the presence or absence of metabolic activation when tested up to limit concentration. There was no evidence of cytotoxicity at this dose level. The study was comparable to guideline without detailed documentation (publication). It is considered that read across to the registered substance is valid and scientifically justifiable.

Additional information
Data for the various test chemicals was reviewed to determine the mutagenic nature of Tridecanol (112-70-9). The studies are as mentioned below:
Ames assay
1.Genetic toxicity in vitro study was assessed for test substance. For this purpose AMES test was performed similar to Guidelines for Screening Mutagenicity Testing of Chemicals (Japan).The test material was exposed to Salmonella typhimurium TA100, TA1535, TA98, TA1537, Escherichia coli WP2 uvrA /PKM101 in the presence and absence of metabolic activation S9. The concentration of test material used in the presence and absence of metabolic activation were 0, 0.61-10000µg/plate. No mutagenic effects were observed in all strains, in the presence and absence of metabolic activation. Therefore test substance was considered to be non mutagenic in Salmonella typhimurium TA100, TA1535, TA98, TA1537, Escherichia coli WP2 uvrA/ PKM101 by AMES test. Hence the substance cannot be classified as gene mutant in vitro.
2. Salmonella/microsome test in the absence of exogenous metabolic activation and in the presence of liver S-9 from Aroclor-induced male Sprague-Dawley rats and Syrian hamsters was performed to evaluate the mutagenic nature of test chemical using S. typhimurium tester strains TA1535, TA97, TA98 and TA100. The study was performed as per the preincubation assay. The test compound was used at a dosage level of 0, 1, 3, 10, 33, 100, 333, 166 µg/plate in the preincubation assay of 48 hrs. Test chemical failed to induce mutation in the S. typhimurium tester strains TA1535, TA97, TA98 and TA100 and hence is negative for mutation in vitro.
3. Gene mutation toxicity study was performed to determine the mutagenic nature of test chemical. Pre-incubation method was performed to determine its mutagenic nature. Test chemical did not induce gene mutations in the S. typhimurium TA100, TA1535, TA98, TA1537, E. coli WP2 uvrA in a bacterial reverse mutation assay. The assay was performed in the presence and absence of S9 metabolic activation system at dose levels of 0, 156, 313, 625, 1250, 2500, 5000 µg /plate. Test chemical did not induce gene mutations in the S. typhimurium strains TA100, TA1535, TA98, TA1537 and E. coli WP2 uvrA in a bacterial reverse mutation assay in the presence and absence of S9 metabolic activation system up to a concentration of 5000 µg/plate and hence is not likely to classify for gene mutation in vitro.
In vitro chromosomal abbreviation study
5. Structural chromosomal aberrations and polyploidy were not induced up to a maximum concentration of test chemical under conditions of continuous treatment, and short-term treatment with and without an exogenous metabolic activation system in Chinese hamster lung(CHL)cells. Hence the substance cannot be classified as genetox in vitro
6. In an in vitro chromosome aberration study, Chinese hamster lung fibroblasts (V79) were incubated with 0.6, 10.0 and 20.0 µg/ml of test material dissolved in ethanol for 4 hours, with and without metabolic activation. The test substance did not increase the incidence of chromosome aberrations in Chinese hamster V79 cells in the presence or absence of metabolic activation when tested up to limit concentration. There was no evidence of cytotoxicity at this dose level. The study was comparable to guideline without detailed documentation (publication). It is considered that read across to the registered substance is valid and scientifically justifiable.
In Vitro Mammalian Cell Gene Mutation Test
8.In Vitro Mammalian Cell Gene Mutation Test was performed Chinese hamster lung fibroblasts (V79) to determine to genotoxicity of the test chemical. The test was performed on HGPRT target gene, with and without metabollic activation at concentartions of 2.0, 7.5, 15.0, and 20.0 ug/ml. 7,12-dimethylbenzanthracene and Ethylmethanosulphonate were used as positive control. Thus, the test chemical did not increase the gene mutation rate in Chinese hamster V79 cells in the presence or absence of metabolic activation at concentrations up to 20 ug/ml. It is concluded that the test substance is negative for mutagenicity in mammalian cells under the conditions of this test.
9.The test chemical was tested for mutagenicity to mammalian cells in a valid study using a method similar to OECD TG 476 up to toxic concentrations. The test was perfomed on mouse lymphoma L5178Y cells, with and without metabollic activation at 10 concentrations at log intervals between 0.013 and 1.0 µl/ml. No increase in the number of revertants was observed. It was concluded that the test chemical is negative for mutagenicity to mammalian cells under the conditions of the test.
Based on the data summarized, Tridecanol (112-70-9) did not induce gene mutation .Hence it is not likely to be mutagenic in vitro.
Justification for classification or non-classification
Thus based on the above annotyation and CLP criteria available for the test chemical does not exhibit gene mutation in vitro and In-Vivo. Hence the test chemical is not likely to classify as a gene mutant in vitro and In-Vivo.
