| contents | Tert‐butylhydroquinone and tert‐butylcatechol positivity as warning lights of skin sensitization to tert‐butylphenol derivatives in adhesives and diabetes devices Ella Dendooven Tania Naessens Kenn Foubert Nina Hermans Olivier Aerts Contact Dermatitis AbstractIntroductionTert‐butylphenol (TBP) derivatives, antioxidants in adhesives and diabetes devices, may provoke allergic contact dermatitis (ACD).ObjectivesThe objective of this study is to report sensitization to TBP derivatives in medical devices and to highlight that tert‐butylhydroquinone (BHQ) and tert‐butylcatechol (TBC) are potential screeners in this regard.MethodsFifteen patients with ACD from adhesives and diabetes devices were patch tested to different TBPs: BHQ 1% pet., TBC 0.25% pet., BHA 2% pet., BHT 2% pet., 4‐tert‐butylphenol (TBP) 1% pet. and 2,4‐di‐tert‐butylphenol (di TBP) 1% pet. The culprit devices (medical adhesives, sanitary pads, diabetes devices) and TBP patch preparations were analysed using gas chromatography‐mass spectrometry (GC–MS).ResultsBHQ (9/13), TBC (7/13), and to a lesser extent BHT (3/15), BHA (2/15) and TBP (2/13) gave positive reactions. Seven patients had developed ACD from adhesives and diabetes devices, respectively, and one patient from sanitary pads. GC–MS analyses of the medical devices and patch test materials confirmed the presence of the patch‐test positive TBPs, or chemically related derivatives, or, interestingly, tert‐butylbenzoquinones (BBQ) were found, that is, spontaneously formed, highly reactive TBP metabolites, likely (pseudo‐) cross reacting with the patch tested TBPs.ConclusionTBPs might be overlooked sensitizers in medical devices, and BHQ and TBC are potential screeners in this regard. 10.1111/cod.14670 http://onlinelibrary.wiley.com/termsAndConditions#vor |
