Application

Isothiazolinones is composed of Chloromethylisothiazolinone (CMI or CMIT) and Methylisothiazolinone (MI or MIT). Isothiazolinones are antimicrobials used to control bacteria, fungi, and algae in cooling water systems, fuel storage tanks, pulp and paper mill water systems, oil extraction systems, wood preservation and antifouling agents. They are frequently used in personal care products such as shampoos and other hair care products, as well as certain paint formulations. Often, combinations of MIT and CMIT (known as Kathon CG).
