Executive summary:

In an OECD Guideline study (TG 404) 500 mg of ADPA (moistened with water) was applied under semi-occlusive conditions to the clipped intact skin of 3 rabbits for 4 hours. There were no signs of irritation at 1, 24, 48, 72 hours and 7 days. The skin response scored according to the method of Draize was all time points 0 (Bayer AG 1982a).
