- Details on test system and experimental conditions:
- METHOD OF APPLICATION: preincubation
DURATION
- Preincubation period: 20 minutes at 37°C
- Exposure duration: 48 hours at 37°C
- Selection time (if incubation with a selection agent): simultaneous with exposure
SELECTION AGENT (mutation assays): trace histidine or tryptophan supplemented
NUMBER OF REPLICATIONS: triplicate
DETERMINATION OF CYTOTOXICITY
- Method: reduction in number of revertant colonies and reduction of bacterial background lawn
The test was performed by mixing 0.1 mL of bacterial culture, 2 mL of molten, trace histidine or tryptophan supplemented, top agar, 0.1 mL of test material formulation and 0.5 mL of S9-mix or phosphate buffer. Five concentrations of the test material formulation and a vehicle control (sterile distilled water) were tested together with the positive controls (0.1 mL). In addition, three minimal agar plates were used for each dose level in the main tests which were performed at the same doses. For the sterility test, 0.1 mL of the test solution of the maximum concentration and 0.5 mL of the S9-mix wre put in each tube, 2.0 mL of top agar were then added to the tube, and the contents of the tube were poured over the surface of the minimal agar plate.
The operations were conducted under lamps with UV absorbent filter.
After approximately 48 hours incubation at 37°C the plates were assessed for numbers of revertant colonies using a colony counter and examined for effects on the growth of the bacterial background lawn with a stereomicroscope.

- Additional information on results:
- Preliminary toxicity test:
Growth inhibition was not observed in any strain either with or without metabolic activation.
Mutation test:
In the two main tests, neither an increase in the number of revertant colonies (more tha twice as many as that of the negative control) nor a dose-related response was observed at any doses in any strains of base-pair substitution type of frame-shit type, with or without metabolic activation.
The revertant colonies of the positive controls showed increases of more than twice that of the negative controls and they were within the limit of controls (mean ± 3SD) in historical data, indicating the study was performed correctly.
In the sterility test on the test solution and the S9-mix, no growth of bacteria was observed.
Applicant's summary and conclusion
- Conclusions:
- The test material was considered to be non-mutagenic under the conditions of this test.
- Executive summary:
The genetic toxicity of the test material was investigated in accordance with the standardised guidelines OECD 471 and in accordance with the Japanese Guidelines for Screening Mutagenicity Testing Of Chemicals, under GLP conditions.
The test material was tested on the following strains of bacteria: S. typhimurium TA 1535, TA 1537, TA 98 and TA 100 and E. coli WP2 uvr A both in the presence and absence of metabolic activation in the form of S9-mix.
In the two main tests, neither an increase in the number of revertant colonies (more than twice as many as that of the negative control) nor a dose-related response was observed at any doses in any strains of base-pair substitution type of frame-shift type, with or without metabolic activation.
The revertant colonies of the positive controls showed increases of more than twice that of the negative controls and they were within the limit of controls (mean ± 3SD) in historical data, indicating the study was performed correctly.
In the sterility test on the test solution and the S9-mix, no growth of bacteria was observed.
Under the conditions of the study, the test material was considered to be non-mutagenic.
