Methylisothiazolinone丨CAS 2682-20-4

Methylisothiazolinone丨CAS 2682-20-4, is a broad-spectrum biocide and preservative widely used in various industries for its strong antimicrobial properties. It belongs to the class of isothiazolinone compounds, which are effective against bacteria, fungi, and algae. MIT is especially valued for its ability to prevent microbial contamination in aqueous systems and products, thus extending shelf life and maintaining product integrity.

● It helps maintain the safety and stability of water-based formulations by preventing bacterial and fungal contamination during storage and use.







● Methylisothiazolinone丨CAS 2682-20-4 helps prevent microbial growth during textile processing and in finished products, thereby reducing odor and fabric damage.

A. Effective Broad-Spectrum Antimicrobial
● Kills a wide range of bacteria (both Gram-positive and Gram-negative), yeasts, and molds.







● Effective at very low concentrations (typically {{0}}.0015% to 0.01%), which minimizes cost and reduces potential toxicity concerns when properly formulated.

Methylisothiazolinone丨CAS 2682-20-4 is a highly effective antimicrobial preservative widely used in personal care, household, and industrial products to prevent microbial contamination and extend shelf life. Its broad-spectrum activity, low use concentration, and water solubility make it a popular choice for aqueous formulations. However, increasing concerns about skin sensitization have led to regulatory restrictions and the search for safer alternatives. Despite these challenges, MIT remains a key preservative in rinse-off formulations, balancing efficacy and safety under regulated use.
