Poly(hexamethylendiamine guanidinium chloride)
Other CAS No.: 34331-58-3;31961-54-3;89697-78-9;57029-18-2
Polyhexamethylene guanidine hydrochloride (short as PHMG) is a guanidine derivative that is used as a biocidal disinfectant, often in the form of its salt Polyhexamethylene guanidine hydrochloride phosphate (PHMG-P). Studies have shown that polyhexamethylene guanidine hydrochloride (PHMG) in solution has fungicidal as well as bactericidal activity against both Gram-positive and Gram-negative bacteria. It also has detergent, anti-corrosive, and flocculant properties and prevents biofouling. PHMG-P is a white powdered solid, and as all polyguanidine salts, readily soluble in water.
Polyhexamethylene guanidine hydrochloride (PHMG) is a broad-spectrum fungicide with long-lasting antibacterial function. Guanidine has high activity, and its salt makes the polymer positively charged, so it is easily adsorbed by various types of bacteria and viruses that are usually negatively charged. Polyhexamethylene guanidine hydrochloride (PHMG) has excellent performance. It is widely used as a sterilant in industrial circulating water sterilization, oil field reinjection water sterilization, aquaculture and animal husbandry sterilization, disinfection of wipes, skin and wound disinfection agents, women vulvar lotion, public places Sterilization, sterilization in textile industry and food processing industry. Polyhexamethylene guanidine hydrochloride (PHMG) disinfectants are cationic surfactants, and must not be compatible with anions to ensure good sterilization effect.
Advantages of polyhexamethylene guanidine hydrochloride(PHMG):
Dilute 25% or 50% of polyhexamethylene guanidine hydrochloride (PHMG) with pure water or ethanol to the required concentration, and then mix with other (non-anionic) raw materials to be used as a disinfectant in various situations.
Polyhexamethylene guanidine hydrochloride(PHMG) has many advantages, such as non-toxic, colorless, odorless, non corrosive, broad spectrum of sterilization, etc. It is very suitable for home disinfection. For example, washing vegetables and fruits; sterilizing and cleaning clothes, towels, sheets and other fabrics; disinfecting the surfaces of high-frequency items such as tableware, toys, doorknobs, sofas, etc.; polyhexamethylene guanidine hydrochloride(PHMG) can also be used to eliminate the smell of kitchen and bathroom drains.
Polyhexamethylene guanidine hydrochloride(PHMG) disinfectant has a good bactericidal effect on bacterial propagules, fungi and some viruses. However, due to the influence of many factors on the unilateral aqueous solution, Polyhexamethylene guanidine hydrochloride(PHMG) compounds are currently used as medical disinfectants mainly with alcohols and other additives. Effective ingredients are compounded. The compounded guanidine disinfectant not only improves the bactericidal effect, but also reduces adverse reactions, which is more convenient for popularization and application.
Disinfection of fruits and vegetables and tableware
Studying the surface, 5-10% of polyhexamethylene guanidine hydrochloride(PHMG) can make the total number of bacteria and coliforms on the surface of the tableware meet the relevant national health standards. Polyhexamethylene guanidine hydrochloride(PHMG) and chlorhexidine acetate disinfection solution soaked in cucumber. After 30 minutes, the surface contamination of Escherichia coli decreased by 3.35, and it also had a good effect on killing natural bacteria on the surface of fruits and vegetables. Polyhexamethylene guanidine hydrochloride(PHMG) disinfectant is much less toxic, corrosive and irritating than chlorine-containing disinfectants or peroxide disinfectants in the disinfection of fruits and vegetables.
Disinfection of aquaculture
According to the 2002 edition of the "Technical Specifications for Fishery Medicine Clinical Trials" test method, the disinfection of Polyhexamethylene guanidine hydrochloride(PHMG) disinfectant with a content of 250g / L was observed to observe the effect of pathogenic Vibrio spp. And its toxicity to marine animals was studied. It has excellent killing effect on Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio floating, Vibrio harveyi, Vibrio anguillarum and Vibrio spp. There is no toxic effect on development and survival, and it can be used for disinfection of aquaculture environment. Adding this product during the water cycle treatment can enhance the activity of water, reduce ammonia and phosphate in water, control algae growth, and naturally balance the ecosystems of sea cucumber ponds and fish and shrimp ponds.
In addition, polyhexamethylene guanidine hydrochloride(PHMG) is also widely used in foreign countries to sterilize pipes, containers, and factory floors during the production of beverages, beer, and food. It is also used for algae removal in lakes, ponds, cooling towers, and fountains. It can also be applied to the anti-mildew problem of oil extraction and various types of building materials.
