SCORING SYSTEM:
Erythema and Eschar Formation:
0 = No erythema
1 = Very slight erythema (barely perceptible)
2 = Well defined erythema
3 = Moderate to severe erythema
4 = Severe erythema (beet-redness) to slight, eschar formation (injuries in depth)
Edema Formation:
0 = No edema
1 = Very slight edema (barely perceptible)
2 = Slight edema (edges of area well defined by definite raising)
3 = Moderate edema (raised approx. 1 mm)
4 = Severe edema (raised more than 1 mm and extending beyond the area of exposure)

- Reversibility:
- other: no effects observed
- Other effects:
- Slight to moderate erythema, in 1 animal extending beyond the area of exposure, was observed in all animals during the course of the study. No edema was noted. The cutaneous reactions were reversible in all animals within 8 days after removal of the patch at latest. The average score (24 to 72 hours) for irritation was calculated to be 1.6 for erythema and 0.0 for edema.
