Materials and methods

Principles of method if other than guideline:
According to BASF-internal standard: Two white Vienna rabbits were treated for 1, 5 and 15 minutes and for 20 hours using occlusive conditions. An application site of 2.5 x 2.5 cm was covered with moistened test substance. After the application time, the skin was washed. Animals were observed for 8 days.
GLP compliance:
no
