Patch test reactions to cocamidopropyl
betaine (CAPB) and its impurities during 2002–2009 (1092 patients)
(++/+++/+++) reactions, n(%)
The aim of the study was to describe
patients with positive patch test reactions to test chemical-related
compounds in an occupational dermatology clinic between 2002 -2009. The test
chemical was tested 1% in distilled water. 1092 patients were patch
tested with Finn Chambers® according to the recommendations of the
International Contact Dermatitis Research Group. The dermal reactions
were read two or three times: on D2/D3/D4 or D2/D3/D6 or D2/D5,
depending on the day of application. The patch test reactions were rated
+/++/+++. 2 of the 1092 patients tested showed allergic reactions to test
chemical. Patch test reactions to test chemical were difficult to
interpret, owing to extremely common irritant reactions. Based on this
observation, the test chemical can be considered to be a potentially
weak skin sensitizer.
