- Additional information on results:
- Observations:
In both mutation assays, there was no reduction of the
bacterial background lawn and no biologically relevant
decrease in the number of revertants at any of the
concentrations tested in all tester strains in the absence
and presence of S9-mix.
In both mutation assays, no increase in the number of
revertants was observed upon treatment with the test
substance under all conditions tested. - Remarks on result:
- other: preliminary test
Any other information on results incl. tables
Comments:
The negative and strain-specific positive control values
were within our laboratory historical control data ranges
indicating that the test conditions were adequate and that
the metabolic activation system functioned properly.
Applicant's summary and conclusion
- Conclusions:
- All bacterial strains showed negative responses over the entire dose range, i.e. no significant dose-related increase in the number of revertants in two independently repeated experiments.
Based on the results of this study it is concluded that Reaction products of Fatty acids, C16-18 and C18-unsatd. and reaction mass of 1,3-alkanediol, 2-(hydroxymethyl)-2-[(methoxymethoxy)methyl]- and 1,3-heteromonocycle-5,5-dimethanol is not mutagenic in the Salmonella typhimurium reverse mutation assay and in the Escherichia coli reverse mutation assay.
