- Details on study design:
- Preparation of the Animals
Approximately 22 hours before the test, the fur from animai no. 1 and approximately 23 hours from animals no. 2 and 3 was removed from the dorsal area of the trunk by using an electronic clipper. Care was taken to avoid abrading the skin, and only animals with healthy intact skin were used.
Exposur e Period
The test item was held in contact with thè skin throughout a 4-hour period.
At the end of the exposure period, residuai test item was not removed.
Confirmatory Test
As a corrosive effect was not observed in thè initial test, two additional animals, each with one patch, were used for an exposure period of 4 hours.
Observation Period
All of the animals were observed for 72 hours after the patch removal.
