10. Purell USA 2009.

Product features: sterilization rate ethanol 62 disinfectant wipes.

1.Peroxide disinfectants: peracetic acid, hydrogen peroxide, etc.

It is a high-level disinfectant, with strong sterilization ability, and has the advantages of broad spectrum, high efficiency and low toxicity, but the disadvantage is poor stability, and the use methods include soaking, wiping, spraying, etc. In addition to hydrogen peroxide (hydrogen peroxide), these disinfectants have some residues.

2.Chlorine-containing disinfectants: calcium hypochlorite (bleaching powder), sodium hypochlorite (84 disinfectant).

As a high-level disinfectant, the main active ingredient of 84 disinfectant is sodium hypochlorite, which is widely used for immersion and disinfection of medical contaminated items, and the wiping and disinfection of object surfaces, with a concentration range of 250 1000 mg L, an action time of 30 45 minutes, and a validity period of 84 disinfectant is limited to 3 months (except for those with stability test reports).

3.Aldehyde disinfectants: glutaraldehyde, compound glutaraldehyde, etc.

It is a high-level disinfectant, which has a good killing effect on all kinds of microorganisms, and the disinfectant is basically not affected by temperature, organic matter, and pH. Compound glutaraldehyde contains surfactants and penetrants that reduce the impact of organic matter in the environment on disinfection effectiveness.

4.Iodine-containing disinfectants: iodophor, iodine tincture, etc.

It is a medium-effect disinfectant, and the sterilization effect is easily affected by organic matter. Iodophor is suitable for disinfection of **, mucous membranes, etc. It is characterized by good solubility, stable properties, and can be stored for a long time, but cannot be used as a sterilant.

5.Alcohol disinfectant: 75% ethanol, etc.

It is a medium-effect disinfectant, mainly used for wiping and disinfection, with the characteristics of fast evaporation and low residue. 75% of alcohol-disinfected contaminated items should be soaked for no less than 30 minutes.

There are a few things to keep in mind: 75% ethanol disinfectant is considered dangerous when stored in excess of 100ml (avoid storing too much at home). In use, it should be wiped and disinfected.

It is forbidden to use spray disinfection methods indoors and elevator halls, especially do not spray alcohol on the body (porous clothes should be soaked in physical or chlorine-containing disinfectant for disinfection), and smokers should stay away from alcohol to prevent fire.

Some people are worried that express delivery and other items carry viruses, so they adopt outdoor spraying alcohol disinfection, which must prohibit open flames to prevent excessive local spraying concentration and the risk of burning in case of open flames. In fact, viruses can only survive in the cells of living organisms, and they basically cannot survive at room temperature, and there is a risk of fire, so this disinfection method is not recommended.

There are also some inefficient disinfectants, which cannot effectively inactivate the coronavirus, are generally stable in nature and can be stored for a long time, but the sterilization spectrum is narrow, so it is recommended not to use them if you have inventory at home. Mainly: phenolic disinfectants:

Coal phenol soap liquid (Lysol); Guanidine disinfectants: amidine carbamate (organic base), chlorhexidine (chlorhexidine); Quaternary ammonium salt disinfectants: benzalkonium bromide (Xinjieer), dumifene (disinfection), etc.

Since it is not effective against the coronavirus, avoid buying the above disinfectants online.

Depending on the needs, there are different types of disinfectants and use scenarios:

The disinfectant solution, the active ingredient is sodium hypochlorite solution, which is mainly used for large-area environmental disinfection and can be used for outdoor yard disinfection.

2. The main ingredient is a brown disinfectant with p-chloro-m-xylenol disinfectant (old housekeeper, Dettol, etc.), which can be used for indoor home, furniture, clothing, flooring, etc.

It's not that other disinfectants can't be used, but from the perspective of cost and effect, this choice is the most effective.

There are five commonly used chemical disinfectants:

One, 2% neutral glutaraldehyde.

Aqueous solution, soaking time is 30 minutes, commonly used for the disinfection of blades, scissors, stitches and microscopic instruments, the sterilization time is ten hours, and the liquid medicine should be replaced once a week.

Second, 10% formaldehyde solution.

The soaking time is 20 to 30 minutes and is suitable for the ureters.

Disinfection of resins, plastics, and plexiglass products such as catheters.

3. 70% alcohol, soaking time 30 minutes, the same use as glutaraldehyde solution, currently more used for soaking sterilized items to maintain the disinfection state, alcohol should be filtered every week, and check the concentration once.

IV, 1:1000 benzalkonium bromide.

solution, soaking time of 30 minutes, although it can also be used for the disinfection of blades, scissors and needles, but because its disinfection effect is not as good as glutaraldehyde solution, it is often used for soaking of sterilized holding forceps.

Fifth, 1:1000 chlorhexidine solution, soaking time is 30 minutes, antibacterial effect is stronger than benzalkonium bromide.

Commonly used disinfectants are 84 disinfectant, peracetic acid, lysophoretic water, bleaching powder, and potassium permanganate.

Disinfectants are divided into household disinfectants, industrial-grade disinfectants, and food-grade disinfectants.

1. Disinfectants are divided into household disinfectants, industrial-grade disinfectants, and food-grade disinfectants;

Disinfectant is a highly effective disinfectant based on sodium hypochlorite;

3. The disinfectant is used to kill the pathogenic microorganisms on the transmission vector, make them harmless, eliminate the pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases.
