Didecyldimethylammonium chloride is a cationic surfactant. It is a double chain quaternary ammonium salt compound, a light yellow transparent liquid at room temperature, easily soluble in water and organic solvents, and chemically stable.

Didecyl dimethyl ammonium chloride is a double chain cationic surfactant, which is a more broad-spectrum and efficient bactericide. It can kill Gram positive bacteria, Staphylococcus aureus, Escherichia coli, Escherichia coli and other bacteria by changing the permeability of bacteria, inactivating proteins, destroying the active enzymes in bacteria cells, etc. At the same time, within 5 minutes of contact, it can effectively kill 48 viruses, including HIV and avian influenza. It will not cause secondary pollution to the environment, is non-toxic, harmless, non irritating, odorless, and has no impact on the human body.Commonly used as anti-corrosion and synergistic agents for personal care products, personal care antibacterial products, home disinfection/deodorization products, hospital environment disinfection, fabric antibacterial detergents, etc.

Didecyldimethylammonium chloride is one of the third generation products of quaternary ammonium salt fungicides, and its ability to kill microorganisms is significantly higher than that of the first and second generation products. It can also be compounded with the first generation products to produce the fourth generation products, and according to reports, its bactericidal performance can be 4 to 20 times higher than the previous three generations of products. At room temperature (20 ℃), the double chain quaternary ammonium salt disinfectant containing 5000mg/L of didecyldimethylammonium chloride has basically no killing effect on the spores of Bacillus subtilis var. niger. Heat 2500mg/L of this double chain quaternary ammonium salt disinfectant to 40 ℃ for 120 minutes to kill spores of Bacillus subtilis var. niger with a logarithmic value greater than 3.0; Heating to 60 ℃ for 30 minutes results in a killing logarithm value greater than 3.0. Heat 1250mg/L of this double chain quaternary ammonium salt disinfectant to 80 ℃ for 60 minutes to kill spores of Bacillus subtilis var. niger with a logarithmic value of>5.00.

Didecyl dimethyl ammonium chloride is used for disinfection in medicine, health, and civilian use; It can also be used as a bactericidal and algal killer for oilfield water injection and industrial circulating cooling water systems; It can also be used as a disinfectant for the environment and production equipment. Its bactericidal effect is superior to the most widely used dodecyl dimethyl benzyl ammonium chloride.

The main use of seasonal salt disinfectant is for antibacterial and bactericidal purposes. Seasonal salt disinfectant is mainly used for skin and mucous membrane disinfection, surgical hand washing disinfection, and medical equipment disinfection in hospitals; Used for disinfection of various public places and production tools and equipment, as well as mold prevention of industrial products and agricultural crops; Sanitation and disinfection of livestock sheds; Aquaculture, algal sterilization; Preparation of plastic antibacterial agents, preparation of compound disinfectants, etc.

In daily life, it mainly appears in the form of quaternary ammonium salt wipes, household disinfectant, disposable disinfectant, and disinfection spray.

At the same time, didecyl dimethyl ammonium chloride is the most promising wood preservative and anti tarnish agent. DDAC has a natural affinity for wood. It is fixed on wood by cation exchange and can be used as a wood preservative in contact with the ground. However, its fixation speed is slow, usually taking two weeks. It has been registered and used in some European and American countries.
