Applicant's summary and conclusion
- Executive summary:
500 mg of the test substance was semi-occlusively applied to the shaved intact skin of 3 male rabbits for an exposure period of 4 h. Evaluation of skin irritation was made according to Draize.
In this skin irritation study Bay Z 7906 was not irritating to the skin.
