In a human maximization study, 25 healthy, male (11) and (14) female subjects aged 18-31 years old were used. Test material was applied under occlusion to the same site on the volar forearm or back of all subjects for five alternate-day 48 hour periods. The patch site was pre-treated for 24 hours with 2.5% aqueous sodium lauryl sulfate (SLS) under occlusion.

И опять же, что такое maximization study?
