Applicant's summary and conclusion

Executive summary:

500 mg of the test substance was semi-occlusively applied to the shaved intact skin of 3 female rabbits for an exposure period of 4 h. Evaluation of skin irritation was made according to Draize.

In this skin irritation study Anilinomorpholinon was not irritating to the skin.
