Quaternary ammonium salts are a commonly used disinfectant, widely used in fields such as household cleaning, healthcare, food processing, and water treatment. Common Quaternary ammonium salt compounds include Tetramethyl ammonium chloride, Hexadecy ltrimethyl ammonium bromide, and Didecyl dimethyl ammonium chloride. These compounds can decompose into positively charged quaternary ammonium ions in water.   The bactericidal mechanism of Quaternary ammonium salts is mainly achieved through two methods: surface activity and microbial membrane disruption:   Firstly, Quaternary ammonium salts have good surface activity, which can reduce the surface tension of the solution and make it easier for the solution to come into contact with microorganisms. The cationic part of Quaternary ammonium salts has hydrophilicity and can adsorb onto the cell membrane of microorganisms, disrupting the cell membrane structure of bacteria and causing leakage of cell contents, thereby killing bacteria. Secondly, Quaternary ammonium salts can also damage the biofilm of microorganisms. Many microorganisms form bacterial or biological membranes to protect themselves, which are composed of lipids and proteins. Quaternary ammonium salts can interact with these membrane structures, alter membrane permeability, cause membrane loss of integrity, disrupt the balance of substances inside and outside the cell, and thus kill microorganisms.   In general, Quaternary ammonium salts achieve bactericidal effects by disrupting the cell membrane structure and biofilm of microorganisms.

The application of Quaternary ammonium salts is very extensive, one of the main applications being as disinfectants, widely used in medical, health, industrial and other fields, and its bactericidal effect and safety are highly recognized. Paris 2024 Olympics are currently being held enthusiastically. So, what are the specific applications of Quaternary ammonium salts as disinfectants in the Paris 2024 Olympics? Please check the details summarized by Ahsuperchem as follows:   1. Cleaning and disinfection of venues and facilities Hygiene guarantee: During the Paris 2024 Olympics, in order to ensure the health and safety of athletes, spectators, and staff, all competition venues, accommodation facilities, public areas, etc. need to be regularly cleaned and disinfected. Quaternary ammonium salts, as an effective disinfectant, may be used in disinfection work in these places due to their broad-spectrum sterilization, low toxicity, and low irritation. Environmental maintenance: In addition to its direct disinfection effect, Quaternary ammonium salts can also help maintain the cleanliness and hygiene of venues and facilities, reduce the growth of bacteria, viruses, and other microorganisms, and provide athletes with a safer and healthier competition environment.   2. Athlete health and safety Personal hygiene products: Some athletes may use personal hygiene products such as disinfectant wipes and hand sanitizers containing Quaternary ammonium salts to keep their hands and other parts of the body clean and reduce the risk of infection. Disinfection of sports equipment: Athletes' sports equipment, such as swimsuits, goggles, running shoes, etc., may be contaminated with bacteria or viruses after prolonged use and contact. Regularly disinfecting these equipment with Quaternary ammonium salt disinfectant can help protect the health of athletes.   3. Protection for audience and staff Disinfection of public areas: Quaternary ammonium salt disinfectants may be regularly sprayed or wiped in public areas such as audience seats, corridors, and restaurants to reduce the spread of viruses and bacteria.   Quaternary ammonium salt disinfectant is widely used in the Paris 2024 Olympics due to its advantages of wider spectrum sterilization, longer lasting antibacterial effect, lower toxicity, and greater stability. We, Ahsuperchem, provides all kinds of Quaternary ammonium salt raw materials for Quaternary ammonium salt disinfectants, such as Didecyl dimethyl ammonium chloride, Benzalkonium chloride, Cetyl trimethyl ammonium bromide etc...which are all our strong products and widely used by our customers at home and abroad.

Alkyl trimethyl quaternary ammonium salts belong to this category. Sodium hydroxide is added to higher fatty amines and reacted with chloromethane under pressure to produce quaternary ammonium salts. The reaction is as follows:   For example, Dodecyl trimethyl ammonium chloride is the main representative of this type of quaternary ammonium salt cationic surfactant, which is easily soluble in water, transparent, and has good surface activity. It can be used as an additive in adhesive solidification liquids.   Alkyl dimethyl benzyl ammonium chloride also belongs to this category. It is made by reacting alkyl dimethyl amine with benzyl chloride, and the reaction formula is:   One representative example is Dodecyl dimethyl benzyl ammonium chloride, which is easily soluble in water and forms a transparent solution. A mass fraction of a few tens of thousands has the ability to sterilize and disinfect. It is non irritating to the skin, non-toxic, and does not corrode metals. It is stable even in boiling water, and its bactericidal ability increases with increasing pH. In addition, it also has good foaming ability.
