Results and discussion

Positive control results:
All 10 animals showed sensitizing effects

Any other information on results incl. tables

When a group of 10 animals was tested with undiluted test substance none was sensitized (whereas all 10 of positive control group were sensitized).

Applicant's summary and conclusion

Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Under the conditions of the present study the test item is not a skin sensitiser.
Executive summary:

The skin sensitizing potential of the test item was determined. A group of 10 guinea pigs was tested with undiluted test substance. No sensitizing effects were observed. All 10 animals in the positive group showed sensitizing effects.
