DURATION
- Preincubation period: 60 minutes
- Exposure duration: at least 48 hours
NUMBER OF REPLICATIONS: Three plates for each strain and dose level including controls
DETERMINATION OF CYTOTOXICITY
- Method: clearing or rather diminution of background lawn or reduction in number of revertants down to a mutation facot < 0.5 in relation to solvent control - Evaluation criteria:
- -A minimum of 3 dose levels were required to evaluate the mutagenic potential of test substance. For a test substance to be evaluated as positive, it must cause a dose dependant increase in the mean revertants per plate of at least one tester strain with a minimum of 2 increasing concentrations of test substance.
-Data sets for Strains TA 1535, TA 1537 and TA 1538 were judged as positive if the increase in mean revertants at the peak of the dose response is equal to or greater than three times the mean vehicle control values.
-Equal to or greater than two fold increase in the number of revertants over the spontaneous number for the strain TA 98, TA100 and E.coli WP2 uvrA was considered as minimal criteria for a positive response. The positive response should not be obtained only at concentrations near to toxic dose levels. - Statistics:
- According to the OECD guideline 471, a statistical analysis of the data was not required.The mean values with standard deviation of revertant colonies were calculated for all strains at each dose level.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative with metabolic activation
ambiguous without metabolic activation
In conclusion, it can be stated that during the described mutagenicity test and under the experimental conditions reported, Glucamide CC did not cause gene mutations by base pair changes or frameshifts in the genome of the tester strains used.Therefore, Glucamide CC is considered to be non-mutagenic in this bacterial reverse mutation assay. - Executive summary:
Glucamide CC was tested in a reverse gene mutation assay in bacteria, strains TA98, TA100, TA1535, TA1537 and TA102 of S. typhimurium up to the limit concentration of 5000 μg/plate with and without metabolic activation. The positive controls induced the appropriate responses in the corresponding strains.There was no evidence of induced mutant colonies over background. Based on the study results it can be stated that Glucamide CC did not cause gen mutations by base pair changes or frameshifts in the genome of the test strains used and is therefore considered to be non-mutagenic in this test system. The study is classified as acceptable and satisfies the requirement for Test Guideline OECD 471 for in vitro mutagenicity (bacterial reverse gene mutation) data.
