Abstract

Human subjects were used to evaluate the skin sensitization potential of several substances used in marketed drugs and cosmetics, as well as other chemical agents. The results show that a modified Draize test is a useful, predictive patch-test procedure. Potentially strong sensitizers show a dose-response relationship when a range of concentrations of test material are used (at induction), whereas weak sensitizers may not; thus a range of concentrations of test materials may be used as a means of disclosing the potential of these compounds to produce delayed skin hypersensitivity.
