Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The skin irritation test included topical application of 0.5 ml of neat Dowfax 2A1 to the ear, and to intact and abraded skin on the abdomen of a male New Zealand White (NZW) rabbit. The animal was bandaged for 24 hours after application of the test material to provide occlusion and prevent grooming of the application site. Twenty four hours after application the bandage was removed and the application sites were graded. Five consecutive daily doses of Dowfax 2A1 were applied to the intact abdominal skin, and the apex of the left pinna, and three consecutive daily applications to the abraded abdominal site. Observations were recorded up to 72 hours after the final dose.

- Details on study design:
- The skin irritation test included topical application of 0.5 ml of neat Dowfax 2A1 to the ear, and to intact and abraded skin on the abdomen of a male New Zealand White (NZW) rabbit. The abdomen of the rabbit was shaved with a straight razor at least three days prior to test initiation. The animal was
bandaged for 24 hours after application of the test material to provide occlusion and prevent grooming of the application site. Twenty four hours
after application the bandage was removed and the application sites were graded. Five consecutive daily doses of Dowfax 2A1 were applied to the intact abdominal skin, and the apex of the left pinna, and three consecutive daily applications to the abraded abdominal site. The study was terminated 72 hours after the final dose. - Positive control:
