Methylisothiazolinone (MIT) is used for controlling microbial growth in water-containing solutions. It can be used on its own or more typically used in a formulation with 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT). It has the properties to be used to control slime in the manufacture of paper products that contact food. In addition, this product serves as an antimicrobial agent in latex adhesives and in paper coatings that also contact food.
