3‐Iodo‐2‐propynyl‐butylcarbamate (IPBC) is a fungicide used in both industrial products and cosmetics. We report the first case of allergic contact dermatitis from airborne exposure to this preservative. A 34‐year‐old female production worker at a paint factory developed dermatitis on air‐exposed skin areas. Patch testing showed a ++ reaction to the preservative IPBC 0·01% in petrolatum. The compound was used as a preservative in wood treatment products manufactured at her work place. Based on animal studies, IPBC is considered safe as a cosmetic preservative. However, widespread use of the chemical might lead to increasing levels of contact allergy, and therefore, close monitoring of IPBC is recommended.
