Method

Ethical approval:
not specified
Details on study design:
50 subjects were dermally exposed to the undiluted test substance with an occlusive patch initially for 72 h (one inch square patch of absorbent cotton twill sealed onto the skin with an elastic adhesive 2 inch square patch). After 7 days, the test substance was applied in the same manner as used for induction procedure and on the same area of the skin.
