Isothiazolinone is mainly composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI). Isothiazolinone exerts its bactericidal effect by breaking the bonds between bacterial and algal proteins. After coming into contact with microorganisms, isothiazolinone can rapidly and irreversibly inhibit their growth, leading to the death of microbial cells. Therefore, it has strong inhibitory and killing effects on common bacteria, fungi, algae, etc. It has the characteristics of high killing efficiency, good degradability, no residue production, safe operation, good compatibility, strong stability, and low usage cost. Can be miscible with chlorine and most anionic, cationic, and nonionic surfactants. At high doses, isothiazolinone has a significant effect on the stripping of biofouling.
Isothiazolone is a broad-spectrum, highly efficient, low toxicity, non oxidizing biocide. Widely used in industries such as oil fields, papermaking, pesticides, cutting oils, leather, inks, dyes, and leather making.
