Isothiazolinones

(CIT/MIT)

【CAS】26172-55-4，2682-20-4

Molecular Formula：C21H38NCl Molecular weight: 115.16

Structure:

2-methyl-4-thiazoline-3-ketone 5-chloro- methyl-4-thiazoline-3-ketone

Properties and Usage:

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 the bond between

bacteria and algae 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, low cost in operation. Isothiazolinones

can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its

biosludge stripping effect is excellent. Isothiazolinonesis a kind of fungicidal with properties of broad spectrum,

high efficiency, low toxicity and non-oxidative, it isthe ideal biocidal in industrial circulating cool water system

and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics

etc.

Using method:

When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the

dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such

as chlorine, and no used in cooling water system containing sulfur. When used together with quaternary amine,

the effect will be better. When used asindustrial fungicide, the dosage of 0.05-0.4% is preferred.

Package and Storage:

25kgin plastic barrel, or confirmed by clients. Storage for ten monthsin room shady and dry place.

Safety Protection:

Corrosive, Avoid contact with eye and skin, Wear splash resistant safety goggles and rubber glores.

Once contacted , flush with water.
