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.

DETERMINATION OF CYTOTOXICITY
- Cytotoxicity test
After being exposed to the test chemical for 3 hours, in the absence or presence of S9, cells were trypsinized and 0.5 x 10 E5 cells per well was seeded in duplicates from two parallel duplicate cultures into 6-well plates in fresh medium. The relative total growth and cytotoxicity was evaluated 24 and 48 hours after seeding. - Evaluation criteria:
- 1) In each concentration, the number of aberrant cells in 200 metaphase cells was presented. Structural aberration was evaluated by classifying to chromosomal
2) Break and exchange, and chromatid break and exchange. A gap was defined as the deletion smaller than the width of chromatid and enumerated, nonetheless, it was not included in the total aberration frequency. As numerical aberration, only polyploidy higher than tetraploid.
3) endoreduplication were evaluated. A cell with more than one type of structural aberration was counted as
4) one positive cell, their percentage of aberration cell was estimated and considered to be the frequency of chromosome aberration. In addition, chromosome aberration types were recorded separately. - Statistics:
- 1) Statistical analysis of chromosomal aberration frequency excluding gaps was performed according to the OECD guideline.
2) In 200 metaphase cells of each group, the numbers of aberrant cells and normal cells were presented.
3) If the dose-dependent increase or the repeated increase was detected. It was evaluated to be positive. The significant difference in the frequence of chromosomal aberration
4) between the negative control and the test substance treatment group was analyzed using Fisher's exact test (Altman, 1993). The test substance was considered to be negative if P-value was lower than 0.05. - Species / strain:

- Executive summary:
Data for the various test chemicals was reviewed to determine the mutagenic nature of Tridecanol (112-70-9). The studies are as mentioned below:
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.
An in vitro mammalian cell gene mutation study was designed and conducted to determine the genotoxicity profile of test chemical when administered to Chinese Hamster Ovary (CHO) cells.
In the genotoxicity test, test substance was administered to CHO cells for 3 hrs at the dose levels of 0, 1.0, 2.5, 5.0 or 10.0 mM and in the absence or presence of exogenous metabolic activation. The results indicate that the test chemical does not give rise to gene mutations when used at concentrations of ≤ 5.0 mM, but when exposed to concentrations above 5.0 mM for 3 hrs, and in organisms with a fully functioning metabolic activation, the test chemical may induce gene mutations. When treated with test chemical and in the absence with S9 liver microsomal fraction, the results show no evidence of genotoxicity when CHO cells are exposed to concentrations of 1.0, 2.5, 5.0 or 10.0 mM, thus indicating that the test chemical does not give rise to gene mutations in organisms who have no or non-functional metabolic activation at the above mentioned concentrations. . Hence the substance cannot be classified as genetox in vitro.

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
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.
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.
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
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.
An in vitro mammalian cell gene mutation study was designed and conducted to determine the genotoxicity profile of test chemical when administered to Chinese Hamster Ovary (CHO) cells.In the genotoxicity test, test substance was administered to CHO cells for 3 hrs at the dose levels of 0, 1.0, 2.5, 5.0 or 10.0 mM and in the absence or presence of exogenous metabolic activation. The results indicate that the test chemical does not give rise to gene mutations when used at concentrations of ≤ 5.0 mM, but when exposed to concentrations above 5.0 mM for 3 hrs, and in organisms with a fully functioning metabolic activation, the test chemical may induce gene mutations. When treated with test chemical and in the absence with S9 liver microsomal fraction, the results show no evidence of genotoxicity when CHO cells are exposed to concentrations of 1.0, 2.5, 5.0 or 10.0 mM, thus indicating that the test chemical does not give rise to gene mutations in organisms who have no or non-functional metabolic activation at the above mentioned concentrations. . Hence the substance cannot be classified as genetox in vitro.
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. Hence the test chemical is not likely to classify as a gene mutant in vitro.
