- Justification for choice of solvent/vehicle: Based on the results from a solubility test: In a non-GLP pre-test, the solubility of the test item was tested in a concentration of 50 g/L in demineralised H2O, dimethyl sulfoxide (DMSO), ethanol and in a concentration of 200 g/L in tetrahydrofuran (THF). THF was chosen as vehicle, because the test item was sufficiently soluble, and this solvent does not have any effects on the viability of the bacteria or the number of spontaneous revertants in the tested concentrations.

EXPERIMENTAL PERFORMANCE
Eight hours before the start of each experiment, one vial permanent culture of each strain was taken from the deep freezer and an aliquot was put into a culture flask containing nu-trient broth. After incubation for eight hours at 37 ± 1 °C, the cultures were used in the experiment. During the test, the cultures were stored at room temperature as to prevent changes in the titre. Per strain and dose, three plates with and three plates without S9 mix were used. Top agar basis was melted in a microwave oven, after melting, 10 mL of histidine-biotin-solution 0.5 mM per 100 mL basis was added and the bottle was placed in the water bath at 43 ± 1 °C.
- Experiment I :
Date of treatment: 02. Aug. 2016
Concentrations tested: 5000 / 1500 / 500 / 150 / 50 µg/plate
Incubation time: 48 h
Incubation temperature: 37 ±1 °C
Tester strains: TA97a, TA98, TA100, TA102, TA1535
Method: plate incorporation method
The following materials were gently vortexed in a test tube and poured onto the selective agar plates:
- 25 µL test solution at each dose level, 100 µL solvent (negative control) or refer-ence mutagen solution (positive control)
- 500 µL S9 mix (see chapter 6.4.18, for test with metabolic activation) or phosphate buffer (for test without metabolic activation).
- 100 µL bacteria suspension (see chapter 6.3.2, test system, culture of the strains)
- 2000 µL overlay agar (top agar)
The plates were closed and left to solidify for a few minutes, then inverted and placed in the dark incubator at 37 ±1 °C.
- Experiment II:
Date of treatment: 09. Aug. 2016
Concentrations tested: 5000 / 2500 / 1250 / 625 / 313 / 156 µg/plate
Incubation time: 48 h
Incubation temperature: 37 ±1 °C
Tester strains: TA97a, TA98, TA100, TA102, TA1535
Method: pre-incubation method
The following materials were gently vortexed in a test tube and incubated at 37 ±1°C for 20 minutes:
- 25 µL test solution at each dose level, 100 µL solvent (negative control) or refer-ence mutagen solution (positive control)
- 500 µL S9 mix (see chapter 6.4.18, for test with metabolic activation) or phosphate buffer (for test without metabolic activation).
- 100 µL bacteria suspension (see chapter 6.3.2, test system, culture of the strains)
After pre-incubation, 2000 µL overlay agar (top agar) was added, the tube was gently vor-texed and the mixture was poured onto the selective agar plate.
The plates were closed and left to solidify for a few minutes, then inverted and placed in the dark incubator at 37 ± 1 °C.
EVALUATION:
The colonies were counted visually and the numbers were recorded. A spreadsheet soft-ware (Microsoft Excel®) was used to calculate mean values and standard deviations of each treatment, solvent control and positive control. The mean values and standard deviations of each threefold determination was calculated as well as the increase factor f(l) of revertant induction (mean revertants divided by mean spontaneous revertants) of the test item solutions and the positive controls. Additionally, the absolute number of revertants (Rev. Abs.) (mean revertants minus mean spontaneous revertants) was given. A substance is considered to have mutagenic potential, if a reproducible increase of re-vertant colonies per plate exceeding an increase factor of 2 in at least one strain can be observed. A concentration-related increase over the range tested is also taken as a sign of mutagenic activity. - Evaluation criteria:

- Additional information on results:
- In the first experiment, VOELOFA Monomer (dissolved in THF) was tested up to concen-trations of 5000 µg/plate in the absence and presence of S9-mix (0.74 % final concentration in the treatment) in the strains TA97a, TA98, TA100, TA102 and TA1535 using the plate incorporation method. VOELOFA Monomer showed no precipitates on the plates at any of the concentrations. The bacterial background lawn was not reduced at any of the concentrations and no rele-vant decrease in the number of revertants was observed in all bacteria strains. The test item VOELOFA Monomer showed no signs of toxicity towards the bacteria strains in both the absence and presence of metabolic activation. The results of this experiment showed that none of the tested concentrations showed a significant increase in the number of revertants in all tested strains, in the presence and the absence of metabolic activation.
On the base of the first experiment, VOELOFA Monomer was tested up to concentrations of 5000 µg/plate in the absence and presence of S9-mix (0.74% final concentration in the treatment) in all bacteria strains using the pre-incubation method. VOELOFA Monomer showed no precipitates on the plates at any of the concentrations. The bacterial background lawn was not reduced at any of the concentrations and no relevant decrease in the number of revertants was observed in all bacteria strains. The test item VOELOFA Monomer showed no signs of toxicity towards the bacteria strains in both the absence and presence of metabolic activation. The results of this experiments showed that the test item VOELOFA Monomer caused no increase in the number of revertants in all bacteria strains compared to the solvent con-trol, in both the absence and presence of metabolic activation. The test item VOELOFA Monomer did not induce a dose-related increase in the number of revertants colonies in all strains, in the presence and absence of metabolic activation. - Remarks on result:

Applicant's summary and conclusion
- Conclusions:
- Under the experimental conditions reported, VOELOFA Monomer did not cause gene mutations in an Ames Test conducted according to OECD 471. Therefore, the test item is considered to be non-mutagenic in this bacterial reverse gene mutation assay.
- Executive summary:
In a bacterial reverse gene mutation assay conducted according to OECD guideline 471, strains TA97a, TA98, TA100, TA102 and TA1535 of Salmonella typhimurium were exposed to VOELOFA Monomer (100% purity) in THF at concentrations of up to 5000 µg/plate in the presence and absence of mammalian metabolic activation. The positive controls induced the appropriate responses in the corresponding strains. There was no evidence of induced mutant colonies over background in all tester strains in both experiments (plate incorporation and pre-incubation). Based on the results, the test item is considered to be non-mutagenic in the bacterial reverse gene mutation assay.
This study is classified as acceptable. This study satisfies the requirement for Test Guideline OPPTS 870.51001; OECD 471 for in vitro mutagenicity (bacterial reverse gene mutation) data.
