DUP040000863 STUDY SYNOPSIS OBJECTIVE To evaluate the contact sensitizing potentialities of two paints. MATERIALS ____________ __................... ...... The two experimental paints were supplied by the Haskell Laboratories of the E, 1, DuPont DeNemours and Company and were identified as follows: Sample 1 hPart A Part B PartC Part D No. 5931 No. 5932 No. 5933 No. 5934 Sample IV Part A Pa rt B Part C No. 5940 No.. 5941 No. 5942 SUBJECTS Twenty-five healthy adult males served as subjects. METHOD The experimental paints were mixed according to the protocol directions two hours before application each day. The experimental paints were applied to one inch square skin sites on the volar forearms of all subjects for a total of fifteen applications on alternate days. A cotton tipped applicator was used to apply the paint. Before each new application the dried paints were removed by peeling. Following a two-week rest period the paints were applied to new skin sites and evaluated twenty-four and forty-eight hours -later. DUP040000864 1 RESULTS The results are recorded, in. the accompanying Tables* No subject presented signs of having become sensitized. During induction some mild irritation was noted, usually erythema and slight glazing. Removing the paint each time may have contributed to this slight non-allergic inflammation. None of the subjects reported any itching, burning or other subjective symptoms associated with contact allergy. .....- ....... CONCLUSIONS Neither paint sample No. 1 or 4 induced any cases of contact sensitization. The contact sensitizing capacity of these paints is very low and not likely to be a significant hazard under conditions of actual use,. Respectfully submitted. A] ,, Ph. D. DUP040000865 E. I.
