Water Treatment Microbiocide

Chemical Name: chloromethylisothiazolinone/methylisothiazolinone

CAS No:26172-55-4/2682-20-4


CMIT/MIT-14 microbicides are high performance, broad spectrum, antimicrobial agents based on the proven isothiazolone chemistry of Ozzie Company. They are effective at very low concentrations in controlling both the planktonic and surface growth of bacteria, fungi and algae and have been produced specifically for water treatment and paper mill applications.Ozzie Company have developed an unrivalled package of regulatory approvals and environmental fate, toxicology, and performance data to support the use of CMIT/MIT-14 in water treatment applications.

Rapid inhibition of growth and macromolecular synthesis

CMIT/MIT-14 causes immediate inhibition of growth on coming in contact with a microorganism.

Broad spectrum activity

CMIT/MIT-14 controls the wide variety of algae, bacteria and fungi found in industrial water systems. Such a broad spectrum product reduces inventory and handling costs, lowers operator training expenses and lessens the risk of dosing error.

Effective at low concentrations

Effective control of such a wide variety of microorganisms at levels as low as 1 ppm active ingredient by CMIT/MIT-14 provides an unrivalled and cost-effective treatment.

Effective against biofilm

CMIT/MIT-14 readily penetrates the surface of adhering biofilm to give effective control of sessile microorganisms.


CMIT/MIT-14 is compatible with chlorine, corrosion and scale inhibitors and most anionic, cationic and non-ionic formulations at normal use levels.

Non-surface active: CMIT/MIT-14 is non-foaming.

Infrequent dosing

CMIT/MIT-14 remains active for long periods of time in the water system, resulting in low service costs.

Easily deactivated

Spills of the concentrated active components of CMIT/MIT-14 are readily deactivated to non-toxic substances by the addition of a slightly acidic solution of sodium metabisulphite or sodium bisulphite.

Application Areas

CMIT/MIT-14 is ideally suited to meet the requirements of an industrial water treatment biocide. CMIT/MIT-14 microbicide is not deactivated by suspended organic matter, and is compatible with other water treatment additives, including chlorine. With the recent change of many cooling towers and paper mills to alkaline operating conditions, it is important to use a biocide such as CMIT/MIT-14 which remains stable at higher pH values. CMIT/MIT-14 is of low toxicity at use levels, easily deactivated and biodegradable. In addition to all these.
