MIT is an antimicrobial used to control slime-forming bacteria, fungi and algae in cooling water systems, fuel storage tanks, pulp and paper mill water systems, oil extraction systems and other industrial settings. It is frequently used in personal care products such as shampoos and other hair care products, as well as certain paint formulations. Moreover, MIT is often used in combination with either Chloromethylisothiazolinone (known as Kathon CG when paired with Methylisothiazolinone) or Benzisothiazolinone (an added antiseptic). MIT is also used to control the growth of mold, mildew, and sapstain on wood products.
