4. Peroxide disinfectants: commonly used are peracetic acid, hydrogen peroxide and peroxyglutaric acid. Peroxyacetic acid is widely used, but its disadvantage is that it is unstable and corrosive to metals. Hydrogen peroxide is mainly used for air disinfection, skin disinfection and mucosal disinfection. The stability of peroxyglutaric acid is better than that of peracetic acid and hydrogen peroxide, but its cost is high, and it is in a state of production suspension, which is basically not seen in the market.

You can smell lysol as soon as you get to the hospital.

Chinese herbal medicine disinfectants need to be mixed with chemical disinfectants because of their high extraction cost and high bactericidal activity. Biological agents, such as biological enzymes and bacteriophages, have specific targets and may not be able to disinfect widely.

Extended information

Disinfectants should be selected: environmental-friendly disinfectants with broad spectrum, high efficiency, quick-acting, long-lasting, non-toxic, tasteless, non-irritating, non-residue and no secondary pollution.

misunderstanding of disinfectant:

1. Do not mix washing powder with disinfectant when washing clothes.

Many people like to add some disinfectant when washing clothes with washing powder, which greatly reduces the cleaning and disinfection effects. Washing powder mostly contains surfactants. If washing powder and disinfectant are mixed, chemical reactions will easily occur, which will weaken their respective efficacy.

If chlorine-containing disinfectant is mixed with acid-containing washing powder, chlorine will be produced. When the chlorine concentration is too high, it will irritate people's eyes, nose, throat and other organs, and even damage people's heart and lung tissues and even endanger their lives.

unless someone in the family suffers from pinkeye, diarrhea, onychomycosis, tinea capitis, etc., or women's menstrual period, puerperium and infancy, it is completely unnecessary to use disinfectant to wash clothes. Frequent use of disinfectant not only reduces the body's own resistance, but also easily causes liver damage.

2, add disinfectant to sterilize when brushing tableware.

disinfection of daily necessities can be done without disinfectant. Solar ultraviolet radiation is the best disinfectant; Washing clothes with soapy water can also complete sterilization; Tableware can be cooked in boiling water for 15-31 minutes.

3. Dilute the disinfectant and apply it to the minor wound.

both are disinfectant, and there are two kinds of product classification: "Xiao" and "Yao". If you treat wounds or disinfect skin, you should use products with the prefix "medicine"; The "Xiao" prefix product is only used for prevention and disinfection and has no therapeutic effect.

it is not optional to choose dressings for treating wounds at home: you can choose some sterilized and packaged cotton balls, gauze and other materials at home, and you can directly cover the superficial wounds with a band-aid.

4, mixed with other daily necessities.

Someone once mixed toilet cleaner with disinfectant to clean the toilet, thinking that it could kill the poison by the way. Unexpectedly, after mixing the two drugs, a chemical reaction occurred, and a large amount of chlorine gas was discharged, which led to suffocation on the spot. Experts suggest that most disinfectants should be used separately with reference to the instructions.

Avoiding misunderstandings and using disinfectant correctly can also prevent colds.

I always feel uneasy about cleaning kitchen supplies with chemical liquid. Therefore, some experts suggest that kitchen supplies such as chopping boards are either wooden or plastic with dark lines. Therefore, it is easy to accumulate dirt and bacteria. When cleaning, you may wish to use hot alkaline water to rinse.

This is because alkaline water has decontamination and sterilization effects, which can wash away the stains in the chopping board. The specific method is to go to the supermarket to buy edible alkali and dilute it with water to make a safe descaling solution, or directly sprinkle the edible alkali on kitchen supplies, then wipe it with water, and then rinse it with clear water. If someone at home has a cold and needs to guard against infection, it can be used with a low-concentration disinfectant.

It should be reminded that alkaline water is irritating to the skin of hands, so it is suggested to wear gloves to protect the skin of hands during cleaning.
