Materials and methods
- Principles of method if other than guideline:
- Standardized test method (BASF-Test)
Before OECD Guideline 404 was established in 1982, skin irritation was tested using an internal method (BASF test). White Vienna rabbits were used. 2 animals were treated for 1, 5, 15 minutes using occlusive conditions. An application site of 2.5 x 2.5 cm was covered with the liquid test substance on a patch. After the application time of 1, 5, and 15 minutes, respectively, the skin was first washed with undiluted Lutrol 9, then with an aqueous Lutrol solution (50 %). The animals were observed for 8 days and skin reactions were recorded 24, 48 hours, 5 and 8 days after treatment. - GLP compliance:
