Results and discussion

Any other information on results incl. tables

The relative mean viability of the test item treated tissues was 98.8% after the 3 minute exposure period and 104.2% after the 60 minute exposure period. (TOS 24)

The relative mean viability of the test item treated tissues was 94.8% after the 3 minute exposure period and 94.7% after the 60 minute exposure period. (TOS 24)

The relative mean viability of the test item treated tissues was 101.9 % after the 3 minute exposure period and 55.9 % after the 60 minute exposure period. (TOS E)

In conclusion all three test items were not considered to have the potential to be corrosive in vivo.

Applicant's summary and conclusion

Conclusions:
None of the samples were considered to be corrosive under the conditions of the study.
Executive summary:

In a well conducted EpiDerm study to evaluate the corrosivity of three test items, the results were as follows,
