- Evaluation criteria:
- A test item is classified as non-clastogenic if:
- the number of induced structural chromosome aberrations in all evaluated dose groups is in the range of our historical control data (0.0-4.0%
aberrant cells, exclusive gaps).
and/or
- no significant increase of the number of structural chromosome aberrations is observed.
A test item is classified as clastogenic if:
- the number of induced structural chromosome aberrations is not in the range of our historical control data (0.0-4.0% aberrant cells, exclusive
gaps).
and
- either a concentration-related or a significant increase of number of structural chromosome aberrations is observed.
Statistical significance was confirmed by means of the Fisher’s exact test (p < 0.05). However, both biological and statistical significance should be considered together. If the criteria mentioned above for the test item are not clearly met, the classification with regard to the historical data and the biological relevance is discussed and/or a confirmatory experiment is performed.
Although the inclusion of the structural chromosome aberrations is the purpose of this study, it is important to include the polyploids and endoreduplications. The following criterion is valid:
A test item can be classified as aneugenic if:
- the number of induced numerical aberrations is not in the range of our historical control data (0.0-8.5% polyploid cells).

Applicant's summary and conclusion
- Conclusions:
- In conclusion, it can be stated that under the experimental conditions reported, the test item did not induce structural chromosome aberrations as determined by the chromosome aberration test in V79 cells ( Chinese hamster cell line) in vitro.
Therefore, Butanedioic acid, sulfo, 1,4-bis(1,3-dimethylbutyl) ester, sodium salt (80% active ingredient) is considered to be non clastogenic in this chromosome aberration test with and without S9 mix when tested up to cytotoxic concentrations. - Executive summary:
The test item Butanedioic acid, sulfo, 1,4-bis(1,3-dimethylbutyl) ester, sodium salt (80% active ingredient), dissolved in deionised water, was assessed for its potential to induce structural chromosome aberrations in V79 cells of the Chinese hamster in vitro in two independent experiments up to 5000 µg/mL(approx. 10 mM of the active ingredient). In each experimental group two parallel cultures were set up. Per culture 100 metaphase plates were scored for structural chromosome aberrations and 500 cells were scored for polyploidy. Toxic effects indicated by reduced cell numbers and/or mitotic indices of about and below 50% of control were observed in all experimental parts. However, in experiment I in the absence and the presence of S9 mix concentrations showing clear cytotoxicity were not evaluable for cytogenetic damage. In both independent experiments, no biologically relevant increase in the number of cells carrying structural chromosomal aberrations was observed after treatment with the test item. The observed statistical significance's and dose-dependency are regarded as being biologically irrelevant. No increase in the frequencies of polyploid metaphases was found after treatment with the test item as compared to the frequencies of the controls. Appropriate mutagens were used as positive controls. They induced statistically significant increases (p < 0.05) in cells with structural chromosome aberrations. In conclusion, it can be stated that under the experimental conditions reported, the test item did not induce structural chromosome aberrations as determined by the chromosome aberration test in V79 cells (Chinese hamster cell line) in vitro. Therefore, the test item is considered to be non-clastagenic in this chromosome aberration test with and without S9 mix when tested up to cytotoxic concentrations.
