Benzoic acid has a higher antibacterial activity in the molecular state than in the ionic state. Because it is related to the pH value, only the molecular benzoic acid can enter the cell and play a role, so the lower the pH value, the stronger the antibacterial effect. When pH=, 60% is not dissociated; When pH=, only undissociated. Benzoic Acids Antibacterial agent Applicable to Apple In high acid foods such as juice, soft drinks and tomato sauce, the acidity of these foods is enough to inhibit bacteria, but not enough to inhibit mold and yeast. Therefore, benzoic acids are mainly added to inhibit mold and yeast. Undissociated acid of 1 can inhibit most molds and yeasts, and undiluted acid can effectively inhibit the spore producing bacteria of pathogenic bacteria.
The raw material of tea polyphenols mainly comes from tea, which has strong antioxidant capacity and can be added to fish oil, vegetable oil, salad oil and other foods. As a natural antibacterial agent, tea polyphenols can control a variety of fungi, such as golden yellow Grape Cocci, Bacillus subtilis and Escherichia coli; At the same time, tea polyphenol is also a natural preservative with low toxicity, which can be used for the preservation of food, cosmetics and health products.
Dew disinfectant is also common. Most people will think that this kind of disinfectant is more expensive, less corrosive and safer than 84. But in fact, this kind of disinfectant is a phenolic preparation. The effective component is p-chloro-m-methylphenol, which is a broad-spectrum anti mold and antibacterial agent. It can prevent mold * * *, and is widely used in clothing disinfection, personal care, and home disinfection.
The commonly used effective disinfectants are chlorine containing disinfectants and 84 disinfectant, 75% alcohol disinfectant for hands, ultraviolet lamp or chlorine dioxide for indoor air, etc. During the supervision and inspection, we found that some schools used disinfection products that could not achieve the disinfection effect, such as antibacterial agents or bacteriostatic agents. As far as hand disinfection is concerned, hand washing free disinfectant should be used instead of hand washing free disinfectant, especially when you have been to hospitals, school clinics, or contacted patients.
Titanium dioxide is a commonly used antibacterial agent of * *. It uses light as a catalyst. When excited by light of certain energy, it will produce many strong oxidizing substances, such as hydroxyl radical (- OH) and superoxide ion (O2 -). These strong oxidizing substances can undergo a series of oxidation-reduction reactions with organic substances to degrade organic substances. Bacteria are one of the organics, so titanium dioxide antibacterial agent has a * * * effect under the action of light.
Just now, the * * * materials of Geely automobile interior have passed the * * test conducted by Guangdong Provincial Microbiology Research Institute. The test results show that the * * * rate of ******** steering wheel is over 99%, which is almost sterile and meets the national Class I standard. It is understood that the key to the powerful performance of the ******* steering wheel is the introduction of an organic compound antibacterial agent, which combines the immediate effect and sustainability of the organic system with the safety and heat resistance of the inorganic system. It can prevent the viral surface from being embedded into human cells by denaturing and destroying the protein on the surface of the virus, so as to achieve the antibacterial effect of * * *. Experiments have proved that the ****** steering wheel can kill bacteria within 2-3 hours after contact with bacteria, which can reach the standard that the bacterial content is better than that of drinking water, especially for Escherichia coli, Staphylococcus aureus, mold and other common bacterial viruses in life, which can play a very good inactivation or bacteriostasis effect.
Functional auxiliaries: antibacterial finishing agent, acarid resistant and antibacterial finishing agent, mosquito resistant finishing agent, deodorant finishing agent, anti ultraviolet finishing agent, far-infrared finishing agent, silver ion antibacterial agent, copper ion antibacterial agent, heating finishing agent, cooling finishing agent, aromatic microcapsule finishing agent, etc.
Class A products are processed during the post-processing of fabrics to maintain the cost performance ratio of clothing while having * * * property. Dipping, padding, coating or spraying and other methods can apply and fix antibacterial agents, so that traditional fabrics also have * * * function.
Nano silver is a metallic silver substance with a diameter of less than 100 nm. Silver nanoparticles are silver particles composed of atomic structure, not silver ions. Nano silver is a solid powder without charge. It is to process metallic silver into metallic silver with particle diameter less than 100 nm through physical and chemical methods. Can Chicheng nano silver ion antibacterial agent be used as a mask? The main reason why it is recognized by so many * * academic institutions is that silver ion itself has unique lethality, can kill poison, and is harmless to humans and animals!
Nano silver * * * coating technology originates from * * medical and health care fields, and the technology is mature and stable. This technology is applied to the floor, that is, the imported antibacterial agent is added to the floor coating, and the nano silver particles will suffocate the cell membrane by entering and destroying the cell membrane, playing the role of sterilization. Nano silver * * * technology is pure physical mechanism * * *, non * * * element sterilization, does not contain any chemical composition and other mixed harmful ingredients, does not release formaldehyde, is harmless to human body disinfectant 2 * * *, and is safe and environmentally friendly.
Examples of food contact substances include polymers (plastic packaging materials), pigments and antioxidants used in polymers, canned coatings, adhesives, materials used in the production of paper and paperboard, adhesives and biocides (antibacterial agents); The products involved include: food packaging tableware , kitchenware, food processing machinery, kitchen electrical products, etc.
