A carpet factory worker, exposed to a number of different dyes, developed a severe hand dermatitis. The handling of warm, wet and freshly-dyed yarn with unprotected hands was thought to have caused the onset of dermatitis. Patch testing indicated that the patient was sensitive to only one of the dyes handled, namely Synacril Red 3B liquid, which is based on the single dyestuff Basic Red 22 (CI 11055). Chemical analysis revealed the dyestuff to be of high purity (greater than 95%), suggesting that sensitization was caused by the Basic Red 22 dyestuff itself and not by an avoidable impurity.
一名地毯厂工人接触了多种不同的染料后，手部患上了严重的皮炎。据认为，用未加保护的手处理温暖、潮湿且刚染好色的纱线是导致皮炎发作的原因。斑贴试验表明，该患者仅对所接触的一种染料敏感，即基于单一染料碱性红22（CI 11055）的Synacril Red 3B液体。化学分析显示该染料纯度很高（大于95%），这表明致敏是由碱性红22染料本身引起的，而非由可避免的杂质所致。
