Summary Background In view of the current epidemic of contact allergy to methylisothiazolinone ( MI ), it is important to clarify the extent of use of MI and related isothiazolinones in paints currently available for the consumer and worker in E urope. Objectives To elucidate the use and concentrations of MI , methylchloroisothiazolinone ( MCI ) and benzisothiazolinone ( BIT ) in paints on the E uropean retail market. Methods Wall paints (n = 71) were randomly purchased in retail outlets in five E uropean countries. The paints were quantitatively analysed for their contents of MI , MCI and BIT by high‐performance liquid chromatography coupled to tandem mass spectrometry. Results MI was found in 93.0% (n = 66) of the paints, with concentrations ranging from 0.7 to 180.9 ppm, MCI in 23.9% (n = 17), ranging from 0.26 to 11.4 ppm, and BIT in 95.8% (n = 68), ranging from 0.1 to 462.5 ppm. High concentrations of MI were found in paints from all five countries. Paints purchased in D enmark and S weden contained especially high concentrations of BIT . Conclusion The use of MI across E uropean countries is extensive. In view of the ongoing epidemic of MI contact allergy, an evaluation of the safety of MI in paints is needed.
