Details on study design:

Approximately 24 hours before the test, the rabbits backs and flanks were shorn using electric clippers equipped with a fine comb, so as to expose an area of skin about 6 cm2.
As no tissue destruction was notedafter a treatment during 3 minutes and 1 hour, the test item was applied, as supplied, at a dose of 0.5g, on an undamaged skin area of one flank of each animal, during 4 hours. The patch was secured in position with a strip of surgical adhesive tape. After the removal of the patch, the treated area was rinsed with distilled water.
On the opposite flank an untreated area was served as the control.
Initially, a single animal was treated. After consideration of the cutaneous responses produced in the dirst treated animal, two additional animals were treated during 4 hours.
The skin reaction were appreciated 1 hour and then 24, 48 and 72 hours after removal of the patch.
This examination consists in assessing the irritation reactions in the treated zone, compared to a control area.
If no reaction is observed 72 hours after the treatment, the study is terminated. In case of persistent reactions, additional observations can be carried out from D4 to D14 in order to determine the reversibility character of the lesions observed.

Details on study design:

0.1g of the test item was instilled, as supplied, into the conjuctival sac of one eye. The other eye remained untreated as control.
Initially, a single animal was treated. After consideration of the ocular responses produced in the first treated animal at D4, two additional animals were treated.

Ocular examinations were performed on both right and left eyes 1 hour, 24, 48 and 72 hours following treatment.
If no reaction is observed 72 hours after instillation, the study is terminated. In case of persistent reactions, additional observations can be carried out from D4 to D21 in order to determine the reversible character of the lesions observed.
