Applicant's summary and conclusion

Conclusions:
The number of revertant colonies in the negative (vehicle) control and positive control groups
in the present study were within the acceptable ranges stipulated at the testing facility. The
positive controls used in the assays with the presence or absence of S9 mix showed clear
positive responses by the respective test strains, as evidenced by the number of revertant
colonies being greater than 2-fold of the respective negative (vehicle) control value.


From the results described above, it was concluded that LiFSI was not mutagenic (negative)
under the conditions employed in the present study.
