- Details on test system and experimental conditions:
- Five dose levels of BENZOESÄURE-ISONONYLESTER in the absence and in the presence 01 metabolic activation were spaced at
half-log intervals. The test #AM-02/09.2 was performed with a concentration range based on the results 01 test #AM-02/09.1. In test #AM-02/09.1 the plate incorporation method, and in test #AM-02/09.2 the preincubation method was used.
Plate incorporation test
In a sterile tube,
- 0.1 ml of the appropriately diluted test material (or 0.1 ml of the solvent)
(or 0.1 ml [0.05 ml for TA 1535] of the strain specific positive control item)
(or 0.05 ml of the positive control items for proving metabolie activation)
- 0.5 ml phosphate buffer
(or 0.5 ml 89 mix in the experiment with metabolie activation)
- 2 ml of molten trace histidine supplemented top agar at approx. 45"C
- 0.1 ml of the bacterial overnight culture
were mixed. Mixing was done in triplicate, for each bacterial strain and for each concentration of the test material. The mixture was then poured onto the surface of minimal agar plates. These plates were incubated at 37 °C for 72 hours and then the number of revertant colonies was counted.
Preincubation test
In a sterile tube, a 0.1 ml aliquot of each one of the bacterial overnight cultures was mixed with a 0.5 ml volume of 89 mix (for tests with metabolie activation) or phosphate-buffer (for tests without metabolie activation). Then either 50 µl of the positive controls 2-Aminofluorene
and 2-Aminoanthracene (+89), 50 µl of the solvent, or 50 µl of the test item solution were added. The tubes were incubated at 30°C for 30 min with gentle agitation. At the end of the incubation period, 2 ml of molten trace histidine supplemented top agar was added to each tube, mixed briefly and poured onto minimal agar plates. These plates were incubated at 37 °C for 72 hours and then the nurnber of revertant colonies was counted. - Evaluation criteria:
- For a test compound to be considered positive, it must (in two independent experiments) cause at least a doubling in the mean revertants per plate of at least one tester strain. This increase must be accompanied by a dose response towards increasing concentrations of the test article. A test article that does not meet these criteria will be called non-mutagenic in bacteria. Single increases in revertant frequencies, which are not dose-related and not reproducible in two independent tests are considered non-relevant. If however these increases do occur in both tests, this will be taken as an indication of a mutagenic effect.

- Additional information on results:
- With two exceptions all five bacterial strains exhibited a positive mutagenic response with the positive controls tested both with and without metabolie activation by S9 mix. The strain TA 1537 showed a limited response to the presence of the positive control item 2-Aminoanthracene in case of the plate incorporation test with metabolic activation (#AM-02/09.1). But the parallel tested additional positive control item 2-Aminolluorene showed
enough activity. The strain TA 102 also showed a limited response to the positive control item 2-Aminoanthracene (tests #AM-02l09.1 and #AM-02/09.2 with metabolie aetivation), but 2-Aminofluorene showed enough activity.

Applicant's summary and conclusion
- Conclusions:
- BENZOESÄURE-ISONONYLESTER did not induce a mutagenic effect in S. typhimurium. It is therefore not considered to be a bacterial mutagen.
- Executive summary:
BENZOESÄURE-ISONONYLESTER was tested for its ability to induce reverse mutations in an in vitro bacterial system. Salmonella typhimurium strains TA 98, TA 100, TA 102, TA 1535 and TA 1537 were treated with the test item by the Ames test plate incorporation (test #AM-02/09.1) as well as by the preincubation method (test #AM-02l09.2). Dose levels covering the range of 50 to 5000 µg/plate, in triplicate both with and without the addition of a metabolising system (Phenobarbital/-ß-Naphthoflavone co-induced rat liver S9 mix) were employed.
A reproducible mutagenic activity of the test compound to any of the tester strains TA 98, TA 100, TA 102, TA 1535 or TA 1537 was not observed with and without metabolic activation. It is therefore concluded, that Benzoesäure-isononylester is not a bacterial mutagen.
