Industrial Preservatives - kathon (CIT/MIT)
KATHON is one of the isothiazolinones, English abbreviation CMIT/MIT, chemical formula C8H9ClN2O2S2, mainly composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2-methyl-4-isothiazolin-3-one (MIT). Isothiazolinones work by breaking the bonds between bacterial and algal proteins. After contact with microorganisms, isothiazolinone can rapidly and irreversibly inhibit their growth, resulting in the death of microbial cells, so it has a strong inhibition and killing effect on common bacteria, fungi, algae, etc.
Isothiazolinone fungicides are also widely used in iron and steel smelting, oil field water injection, oil refinery, thermal power plant, large fertilizer plant, paper factory, textile, water coating, industrial cleaning and other fields.
kathon is a heterocyclic structure, and its bactericidal principle mainly relies on the active part of the heterocyclic ring to destroy the DNA molecules in the bacterial cells, so that the bacteria are inactive. Isothiazolinone fungicides were first formed by the Americans through the halogenation of β-thioketone amide in an inert organic solvent, and are considered to be the best fungicides in water treatment applications for their advantages of high efficiency, broad spectrum and low toxicity. In addition, isothiazolinone bactericides in iron and steel smelting, oil field water injection, oil refinery, thermal power plant, large fertilizer plant, paper factory, textile, water coating, industrial cleaning and other fields are also widely used.
It is characterized by strong antibacterial ability, small application dose, good compatibility, low toxicity, and it has a strong antibacterial effect on a variety of bacteria and fungi. It has high efficiency, good compatibility, wide pH range and natural biodegradation.
