Methylchloroisothiazolinone/methylisothiazolinone (MI/ MCI) is a common preservative used in cosmetic products and is a well-established cause of allergic contact dermatitis (ACD). In 2005, MI alone was approved for use in cosmetic products, with a maximum permitted concentration of 25 times that allowed in the MI/MCI combination . In August 2010, the fi rst cases of MI causing ACD to cosmetic products were published, with reactions occurring to MI in shampoos, conditioners, liquid soaps, moist toilet tissues and makeup remover. We report a series of cases from the Skin and Cancer Foundation in Victoria, of ACD occurring on the hands of parents who have used baby wipes (Huggies™ and Mamia™ brands), where MI was shown to be the causative allergen. We also report cases of ACD to MI in other cosmetic products, including facial moisturising creams and a shampoo. This case series provides further evidence that MI is an emerging allergen in cosmetic products, and is the fi rst reported series anywhere demonstrating that ACD to MI in baby wipes is an important cause of hand dermatitis in parents.
