CAS No. : 26172-55-4, 2682-20-4
Structural Formula :
2-Methyl-4-Isothiazoline-3-one (MI) 5-Chloro-2-Methyl-4-Isothiazolin-3-one (CMI)
Molecular Formula : 115.16
Properties :
Isothiazolinones is composed of 5-Chloro-2-Methyl-4-Isothiazolin-3-one (CMI) and 2-Methyl-4-Isothiazoline-3-one (MI). The bactericidal effect of it is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes. It can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has a strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good co***tibleness, good stabilization, a low cost in operation.
It can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.
It is a kind of fungicidal with properties of broad spectrum, high efficiency, a low toxicity and non-oxidative. It is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, ***ergent and cosmetics etc.
