Methylisothiazolinone (MI) is a preservative found in cosmetic and industrial products. Contact dermatitis caused by either methylchloroisothiazolinone/methylisothiazolinone (MCI/MI or Kathon CG) or MI has shown increasing frequency. The latter is preferably detected through epicutaneous testing with aqueous MI 2000 ppm, which is not included in the Brazilian standard tray. We describe a series of 23 patients tested using it and our standard tray. A case with negative reaction to MCI/MI and positive to MI is emphasized.
甲基异噻唑啉酮（MI）是一种存在于化妆品和工业产品中的防腐剂。由甲基氯异噻唑啉酮/甲基异噻唑啉酮（MCI/MI或卡松CG）或MI引起的接触性皮炎的发生率呈上升趋势。后者最好通过用2000 ppm的水性MI进行皮肤试验来检测，而这并不包括在巴西标准测试盘中。我们描述了一系列使用该测试方法和我们的标准测试盘进行检测的23例患者。重点介绍了1例对MCI/MI反应阴性但对MI反应阳性的病例。
