Type of coverage:
semiocclusive
Vehicle:
unchanged (no vehicle)
Details on dermal exposure:
TEST SITE
- Area of exposure: clipped skin of the dorsal area of the trunk
- Type of wrap if used: the treated skin site was covered with a gauze patch/dental dam, wrapped with an elastic bandage and secured with non-irritating tape.

REMOVAL OF TEST SUBSTANCE
