Applicant's summary and conclusion

Interpretation of results:
Category 2 (irritant) based on GHS criteria
Conclusions:
The skin irritation potential is evluated according OECD439 method. in the test conditions, the mean percent viability of the treated tissues was 2.4%. The test substance is considered as Irritating to skin.
Executive summary:

The skin irritation potential is evluated according OECD439 method. in the test conditions, the mean percent viability of the treated tissues was 2.4%. The test substance is considered as Irritating to skin.
