Any other information on results incl. tables
In other experiments in vitro (with Escherichia coli, Bacillus subtilis, Salmonella typhimurium or Saccharomyces cerevisiae, as well as in the Chinese hamster cells) no genetic toxicity was found.
In the CHO-test sister chromatid exchange in the fraction with S9 -mix was reported, but no dose-response appeared.
Applicant's summary and conclusion
- Conclusions:
- No in vitro toxicity found in assays using bacterial cells.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
