Product Details:

Product Features：

1. This product is a quaternary ammonium salt type cationic surfactant. It belongs to non-oxidizing bacteriostatic agent. Soluble, slightly soluble in acetone, insoluble in ether or benzene, aromatic and extremely bitter;

2. The aqueous solution is alkaline and can generate a lot of foam when stirred. Stable in nature, light-resistant, heat-resistant, non-volatile, easy to store;

3. It has good peeling and cleaning effect of slime, and has a certain deodorizing effect;

4. At low temperature, the clarified liquid will become turbid or precipitated, and the gelatinous body may gradually form a waxy solid; it can reduce the surface tension and emulsify the fat, so it has the function of cleaning and decontamination;

5. It can change the permeability of the bacterial cytoplasmic membrane, make the cytoplasmic material of the bacteria extravasate, and hinder its metabolism; it can inhibit the gram-negative bacteria, mycoplasma, and fungal protozoa;

6. Non-irritating to skin and tissues, non-corrosive to metal and rubber products;

Application:

1. Used as a bacteriostatic preservative. It is used for antibacterial in livestock breeding environment, equipment, wounds, skin, surface of objects and indoor environment;

2. It is used for bacteriostasis in aquaculture water; prevent and control aquatic animals such as fish, shrimp, crab, tadpole, frog and other aquatic animals caused by bacteria such as Vibrio and water vapor single cells, rotten gills, ascites, enteritis, scabies, rot skin disease.

3. Used as antibacterial algicide, slime stripper and cleaning agent. It is widely used in oil field, chemical industry, medicine and industrial water treatment. It is also widely used in emulsification, descaling, solubilization and so on.

Reminders and suggestions：

1. Compatible with anionic surfactants, salt bacteriostats, iodides and peroxides. Preparation packaging materials should be selected: PET, HDPE.

2. Preparation production process: 95% content requires heating equipment. After dilution, a lot of foam will be generated in the filling, so it is not suitable to use a self-priming filling machine.

3. Water quality requirements: Can not be prepared with tap water with higher hardness, preferably deionized water.

4. This product is a bacteriostatic antiseptic for external use. Do not take it internally. Not suitable for bacteriostasis of cystoscope, ophthalmic instruments and synthetic rubber.
