Materials and methods

Principles of method if other than guideline:
Two rabbits were applied 500 µl of the test substance (Macrolexviolett 3R) at the inner side of one of the ears. The test material was fixed by an adhesive bandage for 24 hours. After 1 and 24 hours and 2, 3, 5, 6 and 7 days the skin areas were scored for erythema and edema according to Draize.
GLP compliance:
no

Executive summary:

Two rabbits were applied 500 µl of the test substance (Macrolexviolett 3R) at the inner side of one of the ears. The test material was fixed by an adhesive bandage for 24 hours. After 1 and 24 hours and 2, 3, 5, 6 and 7 days the skin areas were scored for erythema and edema according to Draize. Erythema and edema scores were = 0 at any time point. Macrolex Violet 3R was not irritating in this test.
