Isothiazolinones

Isothiazolinones

【CAS】26172-55-4, 2682-20-4 Molecular weight: 115.16

Properties:　Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking thebondbetween bacteria andalgae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has 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 compatibleness, good stabilization,lowcost in operation.

Isothiazolinones canmixwith chlorine andmostcation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.
