COMPARISON WITH HISTORICAL CONTROL DATA:
The spontaneous mutation frequencies for untreated and solvent treated cultures were within the historical range for the laboratory for all strains in the absence and in the presence of S9.
Any other information on results incl. tables
No increase in the number of revertants relative to the solvent and negative controls was observed in any strain at any concentration in first and second experiments. The results of the first test are presented in tables 1 and 2 below. The results of the second test, conducted over a smaller range of concentrations, were very similar to the first.

Applicant's summary and conclusion
- Conclusions:
- In a reliable study, the C6 alcohol Lorol C6 98% did not increase the reverse mutation rate in histidine dependent bacterial strains of Salmonella typhimurium at concentrations of up to 5000 µg/plate in the presence or absence of metabolic activation (cytotoxicity observed at 5000 µg/plate).
The study was performed in compliance with GLP. Expected results were obtained with negative (buffer) solvent and positive controls. The repeat experiment gave the same results as the initial test.
It is concluded that the test substance is negative for mutagenicity in bacteria under the conditions of the study.
