Applicant's summary and conclusion

Conclusions:
The test substance did not induce reverse mutations in any test strain with or without metablic activation.
Executive summary:

The test material was tested in two independant experiments in test strains TA 98, 100, 1535, 1537 and 1538 according to OECD test guideline 471 at concentrations of 8 -5000 µg/plate. No toxic effects were noted at any concentration. The test substance did not induce reverse mutations in any test strain with or without metabolic activation.
