Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
negative with and without metabolic activation

With and without addition of S9 mix as the external metabolizing system, the test item was not mutagenic under
the experimental conditions described.
Executive summary:

The investigations for the mutagenic potential of the test item were performed using Salmonella typhimurium tester strains TA 98, TA 100, TA 102, TA 1535 and TA 1537, and Escherichia coli WP2 uvrA.

The plate incorporation test with and without addition of liver S9 mix from Aroclor 1254-pretreated rats was used.

Two independent experimental series were performed. In the two series with S9 mix, 10 or 30 % S9 in the S9 mix were used in both series, respectively.

The test item was dissolved in ultrapure water and tested at concentrations ranging from 5.00 to 5000 µg/plate.

Precipitation of the test material on the agar plates did not occur.

Toxicity to the bacteria was (not observed / observed at concentrations >=1580 µg/plate in TA 102).

Daunomycin, sodium azide, 9-aminoacridine, 4-nitroquinolin-N-oxide and cumene hydroperoxide served as strain

specific positive control test materials in the absence of S9 mix.

2-Aminoanthracene and benzo[a]pyrene were used for testing the bacteria and the activity of the S9 mix.

Each treatment with the test materials used as positive controls led to a clear increase in revertant colonies,

thus, showing the expected reversion properties of all strains and good metabolic activity of the S9 mix used.
