2.widely-used biocide, and can act as biocide in circulating cooling water treatment and swimming pool.

CAS No. 26172-55-4, 2682-20-4 Molecular weight: 115.16

Structural Formula:


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


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 is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, 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.

Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, 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, detergent and cosmetics etc..


Notes: 2%, 4% and 8% or any concentration can be supplied on demands.

Benzalkonium chloride 1227

CAS No. 8001-54-5 or 63449-41-2, 139-07-1 Molecular weight: 340.0

Molecular Formula: C21H38NCl

Structural Formula:



Benzalkonium chloride 1227 is a kind of cationic surfactant, belonging to nonoxidizing boicide. It can efficiently withhold algae propagation and sludge reproduction. Benzalkonium chloride also has dispersing and penetrating properties, can penetrate and remove sludge and algae, has advantages of low toxicity, no toxicity accumulation, soluble in water, convenient in use, unaffected by water hardness. It can be also used as anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.

As nonoxidizing boicide, dosage of 50-100mg/L is preferred; as sludge remover, 200-300mg/L is preferred, adequate organosilyl antifoaming agent should be added for this purpose. This product can be used together with other fungicidal such as isothiazolinones, glutaraldegyde, dithionitrile methane for synergism, but cannot be used together with chlorophenols. If sewage is appeared after thrown of this product in circulating cool water, the sewage should be filtered or blown off in time to prevent their deposit in bottom of collecting tank after froth disappearance.

No blending with anion surfactant.

Package and Storage:

25kg or 200kg in plastic barrel, or confirmed by clients. Storage for two year in room shady and dry place.

Safety Protection:

A little smell of almond, no visible stimulation to skin. When contacted, flush with water.
