- Details on study design:
- TEST SITE
- Area of exposure: flanks
A single dose of 0.5 ml of the test substance was prepared on a 6 cm2 dry gauze pad
(Cooperative Pharmaceutique Francaise, 77000 Melun, France) which was then applied to the
right flank of the animals for 4 hours.
The test substance and the gauze pad were held in contact with the skin by means of an adhesive
hypoallergenic aerated semi-occlusive dressing (Laboratoires de Pansements et d'Hygiene,
21300 Chenove, France) and a restraining bandage (Laboratoires 3M Sante, 92245 Malakoff.
France).
The day before treatment, the flanks of each animal were clipped using electric clippers. The
skin of each animal was examined in order to use only animals without any signs of cutaneous
irritation. Animals showing signs of cutaneous irritation, cutaneous defects or pre-existing
dermal injury were not used.
The untreated skin served as control.
REMOVAL OF TEST SUBSTANCE
No residual test substance was noted at removal of the dressing.
OBSERVATION TIME POINTS
1, 24, 48, and 72 hours after removal of dressing

A slight oedema (grade 2) was also observed on day 1 in 1/3 animals. Mean scores over 24, 48 and 72 hours for individual animal were 0.33, 0.67 and 0.0 for erythema and 0.0 for oedema.
