Materials and methods

Principles of method if other than guideline:
To assess the skin irritation potential of the test substance, it was applied to the shaved intact or abraded skin of animals (species not reported). The treated skin areas were observed for erythema and edema 24 and 72 hours after administration of the test substance. Only the intact skin was taken into account for assessment of the skin irritation potential of the test substance.
GLP compliance:
no

Irritant / corrosive response data:
Well-defined erythema was observed on the treated intact skin areas in 2/3 animals 24 hours after exposure ended. One of the treated skin areas exhibited a greater degree of erythema at the 72-hour reading time point, while the effect was completely reversed in the other animal. No erythema was observed in 1/3 animals at the 24- as well as the 72-hour reading time point. No edema was noted at any reading time point.
