Disinfectant refers to a chemical factor that can kill infectious or harmful microorganisms in the external environment, that is, a preparation used to kill microorganisms on the media to achieve disinfection or sterilization requirements.
According to its effect, it can be divided into disinfectant, high-efficiency disinfectant, medium-efficiency disinfectant, and low-efficiency disinfectant.
Sterilizers can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, potassium permanganate, chlorine dioxide, chlorine, copper sulfate, quicklime , Ethanol, etc.
High-efficiency disinfectants can kill all bacterial propagules (including mycobacteria), viruses, fungi and their spores, etc. It also has a certain killing effect on bacterial spores, meeting high-level disinfection requirements, including chlorine-containing disinfectants, ozone, and methyl Hydantoin compounds, double-chain quaternary ammonium salts, etc.
Moderate disinfectants can only kill microorganisms such as mycobacteria, fungi, viruses and bacterial propagules, and meet the disinfection requirements, including iodine-containing disinfectants, alcohol disinfectants, phenol disinfectants, etc.
Low-efficiency disinfectants can only kill bacterial propagules and lipophilic viruses, and meet the disinfectant requirements, including quaternary ammonium salt disinfectants such as benzalkonium bromide, benzalkonium chloride, didecyl dimethyl ammonium chloride, and gluconic acid Guanidine disinfectants such as chlorhexidine, chlorhexidine acetate, polyhexamethylene guanidine and polyhexamethylene biguanide, metal ion disinfectants such as mercury, silver, and copper, and Chinese herbal medicine disinfectants.
Taian Green Industry Co.,Ltd is a professional manufacturer of disinfectant raw materials in China. The company has two production bases, mainly producing quaternary ammonium such as benzalkonium bromide, benzalkonium chloride, and didecyl dimethyl ammonium chloride. Salt surfactants and guanidine disinfectants such as chlorhexidine gluconate, chlorhexidine acetate, polyhexamethylene guanidine and polyhexamethylene biguanide, the products are exported to Europe, the United States, Japan, Korea, Southeast Asia, India And other countries and regions, have been praised and respected by customers.
According to its main ingredients, it can be divided into chlorine disinfectant, peroxide disinfectant, aldehyde disinfectant, alcohol disinfectant, iodine disinfectant, phenol disinfectant, ethylene oxide, biguanide disinfectant and quaternary disinfectant. Ammonium disinfectant.
Chlorine-containing disinfectant refers to a disinfectant that dissolves in water to produce hypochlorous acid with microbicidal activity, and its microbicidal active ingredients are often expressed as available chlorine. Such disinfectants include inorganic chlorine compounds (such as sodium hypochlorite, calcium hypochlorite, trisodium chlorinated phosphate), organic chlorine compounds (such as sodium dichloroisocyanurate, trichloroisocyanuric acid, ammonium chloride T, etc.).
Peroxide disinfectants have strong oxidizing ability, and various microorganisms are very sensitive to them, and can kill all microorganisms. Such disinfectants include hydrogen peroxide, peracetic acid, chlorine dioxide, and ozone. Their advantage is that they leave no residual toxicity on the items after disinfection.
Aldehyde disinfectants include formaldehyde and glutaraldehyde. The principle of this type of disinfection is that a lively alkylating agent acts on the amino, carboxyl, hydroxyl and sulfhydryl groups in the microbial protein, thereby destroying the protein molecule and killing the microbe.
The most commonly used alcohol disinfectants are ethanol and isopropanol, which can coagulate proteins and cause the death of microorganisms. They are moderately effective disinfectants, which can kill bacterial propagules and destroy most lipophilic viruses. Alcohols are often used as solvents for certain disinfectants and have synergistic effects. The usual concentration is 75%.
Iodine-containing disinfectants include tincture of iodine and iodine, which can kill bacterial propagules, fungi and some viruses, and can be used to disinfect skin and mucous membranes. It is often used in hospitals for surgical hand washing and disinfection.
Phenolic disinfectants include phenol, cresol, halogenated phenol and phenol derivatives. Halogenated phenol can enhance the bactericidal effect of phenol. For example, triclosan as a preservative has been widely used in clinical disinfection and antiseptic.
Ethylene oxide, also known as ethylene oxide, is a highly effective disinfectant that can kill all microorganisms. Because of its strong penetrating power, it is often used for disinfection or sterilization after packaging leather, plastic, medical equipment, and medical supplies, and it has no damage to most items. It can be used for the disinfection of precision instruments and valuables, especially for The color of the paper has no effect, and it is often used for the disinfection of books, text and archive materials.
Guanidine and quaternary ammonium salt disinfectants
In addition, there are biguanide and quaternary ammonium salt disinfectants, which belong to cationic surfactants, which have sterilization and decontamination effects. They are generally used for cleaning and disinfection of non-critical items in hospitals, and can also be used for hand disinfection. Ethanol can enhance its bactericidal effect as a skin disinfectant. Because these compounds can change the permeability of the bacterial cell membrane, make the cytoplasmic substance extravasate, hinder its metabolism and play a role in killing bacteria. They are often compounded with other disinfectants to improve their sterilization effect and sterilization speed, and are used for disinfection of non-critical items and hand skin in hospitals.
Guanidine disinfectant is also known as chlorhexidine and its scientific name is chlorhexidine. It is a guanidine disinfectant. It is a safe disinfectant with low toxicity, corrosivity and irritation. Since chlorhexidine is hardly soluble in water, it generally reacts with acid to form a soluble salt to increase its solubility in water. Taian Green Industry Co., Ltd is a professional manufacturer in China and a professional supplier in China. It produces chlorhexidine acetate and chlorhexidine gluconate. Chlorhexidine acetate can be used to wash hands before surgery and prepare for surgery. Chlorhexidine gluconate can be used for mouthwash. Chlorhexidine is compatible with soap or other anionic surfactants. In addition to producing chlorhexidine acetate and chlorhexidine gluconate, Taian Green Industry Co., Ltd is also a professional manufacturer and supplier of polyhexamethylene guanidine hydrochloride and polyhexamethylene biguanide hydrochloride in China.
Quaternary ammonium salt disinfectants encapsulate single-chain quaternary ammonium salts and double-long-chain quaternary ammonium salts, which are non-irritating to skin and mucous membranes, have low toxicity, and have good stability. Taian Green Industry Co.,Ltd mainly produces didecyl dimethyl ammonium chloride (DDAC, D1021), dihydrogenated tallow dimethyl ammonium chloride (D1821), Di(hydrogenated tallow) benzyl methyl ammonium chloride (D1817), Laurylamine in its production base in Binzhou, Shandong Province Dipropylenediamine (Triameen Y 12, 12Y), we are a professional manufacturer and supplier in China. Our products are exported to dozens of countries and regions at home and abroad, and have been praised and respected by customers.
