Description

<p>Benzalkonium Chloride (BAC), a quaternary ammonium cationic detergent and preservative in health care and household products, is a known irritant. We report two cases of patients who developed contact dermatitis after approximately one year of using diluted OSVAN S® (10%BAC) for deodorant treatment in laundry, as recommended by an internet resource. They presented with erythema and scaly pigmentation and pruritis and tenderness in intertriginous areas, especially those in close contact with underwear. Topical corticosteroid ointment treatment led to little improvement. In both cases, their cutaneous symptoms were improved by cessation of using BAC and wearing BAC-contaminated clothing. There have been similar cases reported from Australia and New Zealand that involve BAC in commercial laundly sanitizers, as described as "granular parakeratosis" or "hyperkeratotic flexural erythema". In Japan, BAC is not an ingredient in marketed laundry products. This is the first report of contact dermatitis caused by inappropriate BAC usage for laundry in Japan, and inspired by inaccurate information from the internet.</p>
