What are the main ingredients of disinfectant?

Composition and classification of disinfectant.

Oxidations. The sterilization mechanism is to release new ecological atomic oxygen and oxidize the active groups in the bacteria; Sterilization is characterized by fast and strong action, which can kill all microorganisms, including bacterial spores and viruses. It is mainly used for surface disinfection, such as chlorine dioxide, hydrogen peroxide, ozone, sodium hypochlorite, etc., and this kind of disinfectant is a sterilizing agent.

Aldehydes. The bactericidal mechanism is to denature or alkylate proteins; Bactericidal characteristics are effective against bacteria, spores, fungi and viruses. However, the temperature has a greater effect. Such as formaldehyde, glutaraldehyde, etc. This type of disinfectant can be used as a disinfectant.

Phenols. The bactericidal mechanism is to denature, precipitate, or inactivate the enzyme system; Bactericidal characteristics are effective against fungi and some viruses.

Alcohols. The sterilization mechanism is to denature the protein and interfere with metabolism; Bactericidal characteristics are effective against bacteria, but ineffective against spores, fungi, and viruses, such as ethanol, ethylene propyl alcohol, etc. This type of disinfectant is a medium-potency disinfectant and can only be used for general disinfection.

Alkaline salts. The bactericidal mechanism is to denature, precipitate or dissolve proteins; Sterilization is characterized by killing bacterial propagules, bacterial spores, viruses and some microorganisms that are difficult to kill. Strong bactericidal effect and strong corrosiveness, such as sodium hydroxide, calcium oxide, salt (non-corrosive), etc.

Generally, it can only be used as a preventive disinfectant and sterilization washing solution.

Halogens. The bactericidal mechanism is to oxidize the active genes in the bacterium, which bind to amino groups to denature the protein; It is characterized by being able to kill most microorganisms, mainly surface disinfection, unstable in nature, and the sterilization effect is greatly affected by environmental conditions, such as sodium hypochlorite, chlorogen, etc. This type of disinfectant is a medium-effect disinfectant and can be used as a general disinfectant.

Surfactants.

The bactericidal mechanism is to change the permeability of the cell membrane, so that the cytoplasm leaks, hinders respiration or denatures the protease; Bactericidal characteristics are that it can kill bacterial propagules, but has poor effect on spores, fungi, viruses, and tuberculosis bacteria. The effect is good under alkaline and neutral conditions, such as Xinjieer, 100 poison killing, etc. This type of disinfectant is a low- to medium-efficiency disinfectant and can be used as a general disinfectant.

The disinfectants on the market are mainly hydrogen peroxide disinfectant, hypochlorite disinfectant and quaternary ammonium salt disinfectant, the most commonly used is sodium hypochlorite disinfectant, such as our commonly used 84, which contains chlorine, and the main ingredient is sodium hypochlorite.

According to the composition, disinfectant can be divided into chlorine-containing disinfectant, alcohol-based disinfectant, phenolic disinfectant, iodine-containing disinfectant, etc.

1.Chlorine-containing disinfectant: the main representative product is 84 disinfectant, which is mainly used for disinfection in medical and health care and public places, and the advantages are that it is cheap, not volatile, long-lasting sterilization, and has strong virus inactivation ability.

2.Alcohol disinfectant: the main representative product is ethanol, when the effective concentration is more than 75%, it can kill viruses or bacteria, and 75% alcohol is mainly used for disinfection of the surface of objects.

3.Phenolic disinfectant: The main representative product is chloro-m-xylenol, which is a broad-spectrum antifungal antibacterial agent, which has the effect of killing most bacteria and viruses, and is mostly used in the disinfection of clothing and clothing.

4.Iodine-containing disinfectant: The main representative product is iodophor, which is mainly used for wound or ** disinfection, postoperative wound disinfection.

For disinfectants, mainly chlorine dioxide or alcohol, they will have a sterilizing effect, so well, for some places where this disinfectant should really be used, it will be good for health.

Sodium hypochlorite (Naclo) is the main active ingredient, of course, the solvent is water, which accounts for a larger proportion, and there is some less sodium chloride (NaCl). Because sodium hypochloride itself has strong oxidation and easy decomposition when seen in light, it is not easy to retain for a long time, and it will decompose into other substances after dissolving into water. There is also a medicine that says that after adding a certain concentration, it will have an anti-virus effect.

The main ingredient is peracetic acid. .What disinfectant are you referring to? .Hypochlorous acid. .Sodium hypochlorite (Naclo) is the main active ingredient ,..

Depending on what kind of disinfectant is, most of the disinfectants on the market are 84 disinfectants, and the main ingredient is peracetic acid.

What disinfectant are you referring to?

The chemical formula of 84 disinfectant solution is Naclo.

Sodium hypochlorite, the chemical formula is crying plexus naclo, molecular weight, the solid is white or pale yellow powder, extremely unstable, the melting point is 19 (heptahydrate 21 (hexahydrate.)5 (pentahydrate (hemihydrate 78 (anhydrous), easy to decompose.

Industrial products are colorless or light yellow liquids, with strong oxidation Zheng Min cherry properties, can gradually separate and liberate oxygen, and decompose very quickly when exposed to light or heating. It is very dangerous to mix with reducing substances and organic matter, which can make the red litmus paper black and then fade. Nazhao has excellent disinfection performance.

The aqueous solution is evaporated in a vacuum to obtain colorless to yellow-green deliquescent hydrated crystals.

Disinfection principle. 84 disinfectant is generally prepared by the reaction of chlorine (Cl2) and sodium hydroxide (NaOH), and sodium hypochlorite in the reaction product is the main component of the disinfectant.

Sodium hypochlorite is a strong electrolyte, which is first ionized in water to form hypochlorite ions (clo), hypochlorite ions are hydrolyzed to form hypochlorous acid, and further decomposed to form new ecological oxygen [O] (a substance directly composed of oxygen atoms), its chemical properties are very active, with strong oxidizing power, and play a great role in the disinfection process.

The main components of oxidizing disinfectant generally contain chlorine dioxide, sodium hypochlorite and ozone, as well as hydrogen peroxide, etc., generally such a disinfectant sterilization mechanism is to release a new ecological atomic oxygen and oxidize the active genes in the bacteria, the use of such a dissipation venom, the biggest advantage is that the effect is very fast, and strong, can kill all microorganisms, including germs and bacterial spores, the use of this disinfectant can sanitize the surface of bacteria, and very fast.

Aldehyde disinfectants generally contain more formaldehyde, formaldehyde is a substance known by more people in life, and it is a substance that has a greater impact on physical health. The sterilization mechanism of this disinfectant is to denature or alkylate the protein, so you must be cautious when using this disinfectant.

The main ingredient in alcohol disinfectant is ethyl propanol or ethanol, and the sterilization mechanism liquid hall is to denature the protein, and then interfere with metabolism.

The disinfectant of alkali and hidden salt mainly contains salt or calcium oxide, as well as sodium hydroxide, etc., the sterilization mechanism of such a disinfectant is also to denature the protein and precipitate or dissolve, the sterilization effect is very strong, and it is corrosive, we must be careful in the process of use, this disinfectant can only be used as a preventive disinfectant and sterilization detergent. The edible salt that people usually eat actually has a certain anti-inflammatory and sterilizing effect, which is why some bacon will not deteriorate after being sprinkled with a little salt.
