Application: 

CMIT/MIT is widely used in various industries, including personal care products, paints and coatings, adhesives, and industrial water treatment. It is effective against a broad spectrum of microorganisms, including bacteria, fungi, and algae.

  1. In personal care products, CMIT/MIT acts as a preservative to prevent the growth of bacteria, fungi, and other microorganisms that can cause product spoilage and degradation. It helps maintain the safety and shelf life of products such as shampoos, lotions, and household cleaners.
  2. In paints, coatings, and adhesives, CMIT/MIT is added to prevent microbial growth, ensuring the quality and longevity of these products.
  3. CMIT/MIT is also used in industrial water treatment applications, such as cooling towers, to control microbial contamination and inhibit the growth of biofilms.

Storage Notes: Sealed stored in cold, dry, good ventilated place, avoid high temperature and moist.
