Materials and methods

Principles of method if other than guideline:
BASF-Test. Two animals were treated for 3 min or 1 h using occlusive conditions. An application site of 1x1 cm was covered with the liquid test substance. After the application time the skin was washed with water and water/Lutrol (1:1). The animals were observed for 8 days and skin changes were recorded daily.
GLP compliance:
no
