Species / strain
- Species / strain / cell type:
- S. typhimurium TA 1535, TA 1537, TA 98, TA 100 and E. coli WP2
- Metabolic activation:

- Test concentrations with justification for top dose:
- 1.5, 5, 15, 50, 150, 500, 1500 and 5000 µg/plate with and without metabolic activation.
The maximum dose level of the test item was selected as the OECD 471 recommended dose level of 5000 µg/plate. - Vehicle / solvent:
- - Vehicle/solvent used: DMSO
- Lot No. 184106
- Justification for choice of vehicle: The test item was immiscible in sterile distilled water at 50 mg/mL but was fully miscible in DMSO at the same concentration

- Remarks:
- DMSO
- True negative controls:
- no
- Positive controls:

- Remarks:
- -S9: ENNG (2 µg/plate) f. WP2uvrA, (3 µg/plate) for TA100 + (5 µg/plate) f. TA1535; 9AA (80 µg/plate) f. TA1537; 4NQO (0.2 µg/plate) f. TA98 / +S9: 2AA (1 µg/plate) f. TA100, (2µg/plate) f. TA1535 + TA1537, (10µg/plate) f. WP2uvrA; BP (5 µg/plate) f. TA98
- Details on test system and experimental conditions:
- METHOD OF APPLICATION:
Initial mutation test: Plate incorporation
Confirmatory mutation test: Pre-incubation
DURATION
- Pre-incubation period: 20 min at 37 ± 3 °C
- Exposure duration: 48 to 72 h
NUMBER OF REPLICATIONS: triplicates each in two independent experiments
DETERMINATION OF CYTOTOXICITY
- Method: observation of bacterial growth inhibition - Evaluation criteria:
- A test item was considered mutagenic (positive) if the following criteria were met:
- a dose-related increase in mutant frequencies over the dose range tested
- a reproducible increase at one or more concentrations
- biological relevance against historical control ranges
- a fold increase greater than two times the concurrent vehicle control for TA100, TA98 and WP2uvrA or a three-fold increase for TA1535 and TA1537
A test item was considered non-mutagenic (negative) if the above mentioned criteria were not met. - Statistics:
- Statistical significance was confirmed by using Dunnetts Regression Analysis (p < 0.05) for those values that indicate statistically significant increases in the frequency of revertant colonies compared to the concurrent solvent control.

Applicant's summary and conclusion
- Conclusions:
- Under the tested conditions, the test compound was not mutagenic in any of the four tested S. typhimurium strains (TA 98, TA 100, TA 1535 and TA 1537), nor in the E. coli strain WP2uvrA with and without metabolic activation up to 5000 µg/plate.
