Non-occupational allergic contact dermatitis from 2-N-octyl-4-isothiazolin-3-one in a Japanese mattress gel-sheet used for cooling.

摘要

In a review of the current literature, we found propylene glycol as the cause of an allergic contact dermatitis in self-adhesive ECG electrodes in two cases (2, 5). Furthermore, guar gum - largely used in food industry and plastics - could be a possible allergen in the gel part of the ECG electrodes although no case of contact dermatitis to guar gum has been reported so far. Guar gum has caused asthma (6) and contact urticaria (7).
