ABSTRACT
Preservatives and disinfectants are common and well-documented causes of allergic contact dermatitis (ACD), where there are data available indicating incidence and prevalence. In contrast, contact urticaria (CoU) to preservatives and disinfectants is far less common. As a consequence of this, the literature consists almost entirely of case reports with just a few case series, with a notable lack of studies documenting the actual incidence and prevalence of CoU to preservatives and disinfectants.
