Will the disinfectant be invalid after opening it for a long time?

If the disinfectant is left open for a long time, it will become ineffective for a long time, because the disinfectant will not be used normally after being placed for a long time, and in addition, it may cause contact with air and reduce its effectiveness.

It's 1 to 4 bacteria that grow, and they're still going to be put in the mouth, and none of them will fail, because there's still nothing that can change them.

After the disinfectant is opened, as long as the cap is tightened and used within the expiration date, it should not be invalid, and the effect is still the same as new, and there will be no problems.

Yes. This is possible to be invalidated.

This is a chemical and is subject to change.

Yes. The composition of the disinfectant is a chlorine-containing disinfectant, which can effectively kill the virus. Normally, after the disinfectant water is evaporated into the air, the chemicals can cause damage to the mucous membranes of the human respiratory tract. Therefore, it is usually formulated in a certain proportion for use.

Usually the ratio is 2 or 5, followed by 2ml of disinfectant in 1000ml of water, or 5ml of disinfectant in 1000ml of water, diluted into a certain ratio, and then disinfected the item or air. Usually after 30 minutes, it can effectively kill the virus. After using the disinfectant water, it is recommended to store it in a cool, dry, closed environment.

The disinfectant has a certain shelf life and will not expire within the shelf life.

After opening, it can generally be put for about a week, and it will not fail, and it is easy to slowly fail after a long time in contact with the air.

After opening the disinfectant, it will not fail for a long time, and after opening, a redox reaction will occur when it comes into contact with the air, so it will be ineffective.

It can't be used. The main ingredient of disinfectant water is sodium hypochlorite, if the disinfectant water expires, the sodium hypochlorite in it will be decomposed into hypochlorous acid and sodium chloride, which are non-toxic ingredients and have no disinfection effect. <

The disinfectant solution cannot be used after 2 years of expiration. The main ingredient of disinfectant water is sodium hypochlorite, if the disinfectant water expires, the sodium hypochlorite in it will be decomposed into hypochlorous acid and sodium chloride, which are non-toxic ingredients and have no disinfection effect.

In a sense, the disinfectant has expired, and if the amount of the disinfectant stock solution is increased, the effective concentration in the used solution may be increased, but this may also cause greater harm to the disinfection object.

For ordinary consumers, it is difficult to grasp the preparation because it does not have the conditions to determine the concentration of disinfectant, so it is recommended not to use expired disinfectant as much as possible.

1 Household 84 disinfectant has an expiration date, and the validity period is 12 months. The main ingredient of 84 disinfectant is active chlorine, the content is in the range of 34% and 46%, chlorine is volatile, if it is stored for too long, or the bottle is not tightly capped after use, it will gradually reduce the efficiency due to chlorine volatilization, until it fails. Pay attention to the storage of 84 disinfectant, cover tightly after use, avoid sunlight, and generally use up a bottle for more than a year.

84. The disinfectant should be stored separately from the acid, and should not be mixed. The storage area should be equipped with emergency response equipment for spills and suitable containment materials.

2 Valid for one month.

1. Disinfectants are also often referred to as chemical disinfectants. Disinfectants are used to kill pathogenic microorganisms on the transmission vector, make them harmless, eliminate pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases. Disinfectants can be divided into sterilizers, high-efficiency disinfectants, medium-potent disinfectants, and low-efficiency disinfectants according to their level of action.

2. Disinfectants can be divided into sterilizers, high-efficiency disinfectants, medium-efficiency disinfectants, and low-efficiency disinfectants according to their level of action. The sterilant can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, chlorine dioxide, chlorine, copper sulfate, quicklime, ethanol, etc.

3. Medium-effect disinfectants can only kill microorganisms such as mycobacteria, fungi, viruses and bacterial propagules to meet disinfection requirements, including iodine-containing disinfectants, alcohol-based disinfectants, phenolic disinfectants, etc. Inefficient disinfectants can only kill bacterial propagules and esterophilic viruses to meet the requirements of disinfectants, including quaternary ammonium salt disinfectants such as benzalkonium bromide, biguanide disinfectants such as chlorhexidine, metal ion disinfectants such as mercury, silver, copper and Chinese herbal disinfectants.

4. Definition of disinfectant Disinfectant refers to the preparation used to kill pathogenic microorganisms on the vector and make them harmless, which is different from antibiotics, and its main role in disease prevention is to eliminate pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases. Disinfectants are also often referred to as "chemical disinfectants".

The main active ingredient of 384 disinfectant is sodium hypochlorite, sodium hypochlorite is easy to decompose into active chlorine, chlorine is volatile, if it is stored for too long, or the bottle is not tightly capped after use, it will gradually reduce the efficiency due to chlorine volatilization, until it fails. After the expiration of 84 disinfectant, the effect must be greatly weakened, or even no disinfection effect.

41.To disinfect clothes, 50ml (about one cap) of disinfectant solution is diluted with water at a ratio of 1:50, and the clothes are soaked for 15 minutes before washing.

2.For furniture disinfection, take 50ml of disinfectant solution and dilute it with water at a ratio of 1:50, soak the rag and then wring it out and wipe the furniture.

4.To disinfect floors and sinks, take 50ml of disinfectant solution and wipe it with water diluted at a ratio of 1:50.

5.To disinfect the toilet, pour 50ml of disinfectant into the toilet bowl and scrub it.

6.Keyboard and mobile phone disinfection, disinfectant and water are diluted 1:50, and mobile phones and keyboards can be easily disinfected by wiping them.

Disinfectant is a powerful disinfection tool that is more common in our lives, but because of its strong disinfection effect, it does not need to be used often, so what will happen if the disinfectant is left for too long?

Generally speaking, it will not be good, but the disinfection effect will not be so strong.

The main ingredient of 84 disinfectant is active chlorine, the content is in the range of 34% and 46%, chlorine is volatile, if it is stored for too long, or the bottle is not tightly capped after use, the efficiency will be gradually reduced due to chlorine volatilization, until the cave state fails.

It needs to be judged according to the time situation, generally speaking, the longer the storage time, the weaker the effect of the disinfectant.

The disinfection function of 84 is mainly tested for this strong oxidation. Expired 84 will only affect its disinfection effect, but be careful not to mix 84 disinfectant with other detergents or disinfectants, as this will increase the concentration of chlorine in the air and cause chlorine poisoning.

As can be seen from the above, expired 84 disinfectant will not produce other toxic substances, but the disinfection effect will be reduced, so expired 84 disinfectant can still be used normally. If you want to check whether the purchased 84 disinfectant is expired, you can use a Nayuan teacup with more tea dirt, pour some 84 disinfectant, and let it stand for a while, if the tea dirt disappears, it means that the 84 disinfectant has not expired or the effect is OK, if the tea dirt does not disappear, it means that the 84 disinfectant has expired, and you can pour it out.

About 20 minutes.
