TEST SITE
The day before the treatment the skin area on the back of the rabbits was clipped as closely as possible with an electric clipper.
The test item was applied to a 16-layer gauze patch (2.5 x 2.5 cm) and moistened with the vehicle, the patch was placed on the skin and secured semi-occlusively with adhesive Gothaplast tape (2.5 cm). After an exposure time of 3 minutes. The first patch was removed, the treated skin was cleaned with mild soap and lukewarm water. A first assessment of the skin reaction took place immediately after the termination of exposure.
No corrosive effects were observed and a second patch with test item was applied on the rabbit back. In order to improve the patch securing the trunk of the animal was additionally wound with 5 cm wide adhesive Gothaplast tape. After an exposure time of 1 hour the second patch was removed, the treated skin was cleaned with mild soap and lukewarm water. The skin reaction was first assessed immediately after the termination of exposure.
Again no corrosive effects were observed and the exposure time was extended to 4 hours. An amount of the test item was applied on a third patch, was moistened with 0.1 ml olive oil and put on the skin. Adhesive Gothaplast tape (2.5 cm and 5 cm wide) served again as the semiocclusive securing. After a 4-hour exposure time the third patch was removed, the treated skin was cleaned with mild soap and lukewarm water. The first assessment of the skin reaction took place again immediately after the termination of exposure.
A confirmatory test with two animals was carried out after the initial test. The animals were treated the same way as in the initial test except that the animals were only exposed for 4 hours.
