1.Oil & gas industry: strong biocide and algicide ability, to prevent pipe from being blocked and rusted

2.Water treatment : Used as bactericide, kill green,black spot and mustard algae;

3.Detergent: raw detergent materious;


Dodecyl dimethyl benzyl ammonium cloride is a kind of cationic surfactant, a nonoxidizing biocide.

It can efficiently kill bacteria and algae ,and con-reproduction and sludge growth. Dodecyl dimethyl benzyl ammonium cloride 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 to use, unaffected by water hardness.


As nonoxidizing biocide, the preferred dosage is 50-100mg/L; as sludge remover, 200-300mg/L dosage is preferred, and it can add the appropriate amount of silicone antifoaming agent if needed 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.

Product Avantages
 1.Dodecyl dimethyl benzyl ammonium cloride owns the broad spectrum, highly effect to be sterilization and algicide,specially for killing the sulfate-reducing bacteria.

2.Soluble in water, easy to use, free from the influence of water hardness, and a strong sticky-mud exfoliation.

3.Low toxicity and no toxicity accumulation, unlike chlorine causes secondary pollution, as it contains residual chlorine if used in water treatment.

4.In the system which can not control if use chlorine, dodecyl dimethyl benzyl ammonium cloride can effectively control the growth of algal blooms and slime.

5.Even under the different range of PH value, dodecyl dimethyl benzyl ammonium cloride has strong biocide ability, as it can be used both in acidic and alkaline conditions.

6. Owning dispersion and penetration effect, dodecyl dimethyl benzyl ammonium cloride can penetrate and remove slime and peel attached algae .It also has oil degreasing and cleaning ability.
