Background: Different textile constituents may act as allergens and/or irritants and provoke textile contact dermatitis (TCD).Objectives: To report a case of TCD caused by ethylene glycol monododecyl ether and 2.4-dichlorophenol present in a bikini.Methods: A woman presented with an eczematous, pruritic rash in the area of the straps and back. Patch testing was performed with the (extended) European baseline, textile, sunscreen and photo-patch series, the bikini "as is", and ethanol and acetone extracts of the bikini. Thin-layer chromatography (TLC) of the extracts and gas chromatographymass spectrometry (GC-MS) analysis were used to elucidate the culprit(s).Result: Positive reactions were found to the bikini "as is", and to the ethanol and acetone extracts. Patch testing with TLC strips showed a strong reaction to particular fractions (3 and 4). GC-MS was performed to identify substances in each fraction, and those suspected to be skin sensitizers were patch tested. On day 4 positive reactions to ethylene glycol monododecyl ether (IR) and 2.4-dichlorophenol (++) were observed.
Conclusion:A myriad of chemical compounds can be found in clothing. Ethylene glycol monododecyl ether and 2.4-dichlorophenol were identified as the potential culprits of this bikini TCD.
