Materials and methods

Principles of method if other than guideline:
Before OECD Guideline 404 was established in 1982, skin irritation was tested according to the acknowledged Draize test method.
An amount of 0.5 mL of test material was applied to a skin area of 2.5 x 2.5 cm under occlusive conditions for 24 hours. The application site was either intact or scarified. The application site on the intact skin was located dorsally whereas the area of scarified skin was located on the left side. Skin findings were assessed after 24 hours, 48 hours, 72 hours and after 8 days. The assessment of the findings was based on the Federal Reg. 38, No. 187, Para. 1500.41, page 27029 (1973).
