Methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI), a widely used preservative/biocide, was included in the European baseline series in 1988 at a concentration of 100 ppm (0.01%) in a ratio of 3:1 (1). Although recently it has been recommended to be tested at 200 ppm (0.02%), many centres still test it at 100 ppm (2). MCI/MI is also included in the TRUE Test®, offering an alternative patch test technique. The objective of the current investigation was to compare the diagnostic performance of MCI/MI 0.01% aq. with MCI/MI in the TRUE Test®.
