Shelf life and storage conditions of hydrogen peroxide. Shelf life of hydrogen peroxide Storage conditions for working solutions of hydrogen peroxide

Antiseptic Hydrogen peroxide is available in 3 forms:

• Shelf life of 3% hydrogen peroxide solution for external and local use - 2 years .
• Shelf life Perhydrol - a solution of 35% hydrogen peroxide for breeding, subject to proper storage and integrity of the package - 6 months. Ready solution - no more than 24 hours.
• Shelf life Hydroperit- tablets for the preparation of a 35% solution - 2 years. Ready solution - no more than 24 hours.

On tablets, the expiration date is indicated on the blister. On solutions, it is stamped on the bottle and on the carton.

Under the influence of direct sunlight and in severe frost, the chemical elements of the preparations decompose and disappear, so the shelf life is reduced to 2-3 days.

Hydrogen peroxide can be used 5-10 days before the expiration date under proper storage conditions.

At the end of the period, Hydroperit begins to crumble, and perhydrol and 3% hydrogen peroxide solution evaporate.

Signs of expired or defective goods:

1. The integrity of the package or vial is broken.
2. No juice storage on packaging.
3. Traces of evaporation on the bottle.
4. Turbid solution.
5. Presence of sediment.

Hydrogen peroxide in any form can be used within a month after the expiration date, if the integrity of the package has not been violated. Diluted solutions should not be used after a day, since the active substances evaporate in the air, and the product will be useless.

A darkened bottle of a 3% solution and a dense package of Hydroperite protects Hydrogen Peroxide from evaporation and decay of active substances, this helps the antiseptic to be stored for quite a long time. Perhydrol is stored in transparent packaging, which significantly reduces the shelf life.

How to store at home

Hydrogen peroxide in any form release is stored in a dark place at a temperature not higher than +15 o C.

The antiseptic preparation should be stored in a tightly closed package in a specially designated first-aid kit that does not let light through. At temperatures exceeding those allowed for storage, hydrogen peroxide should be transferred to a shelf in the refrigerator door.

It is not necessary to pour the solution into another container. We allow this option only if the integrity of the package is damaged. It is necessary to find a container as close as possible to the original. When opening, indicate the date.

Do not store hydrogen peroxide:

• near heaters;
• when exposed to direct sunlight;
• in the freezer and main compartment of the refrigerator.

Hydrogen peroxide analogues:

• Chlohexidine;
• Antiseptic;
• Biosept;
• Bonaderm;
• Hydrogen peroxide;
• Ichthyol ointment;
• Cutasept;
• Myristamide;
• Septocid;
• Sterillium;
• Farmaseptil.

Rules for storing the drug in pharmacies and clinics

In accordance with the order of the Ministry of Health and Social Development of the Russian Federation N 706n "On Approval of the Rules for the Storage of Medicines", the antiseptic agent Hydrogen Peroxide should be stored:

1. A solution of Hydrogen Peroxide 3% and Pedhydrol is stored in refrigerators at a temperature not exceeding +15 ° C.
2. Hydoperite is placed in special cabinets on a shelf next to similar antiseptics.

According to SanPiN 2.1.7.2790-10, large batches of expired or defective goods are destroyed at manufacturing plants with a special license.

Small quantities of hydrogen peroxide are destroyed in pharmacies. The antiseptic is dissolved in water and poured out.

During transportation, antiseptic preparations must be packed in special containers where the required temperature and humidity are maintained. Carriers must be authorized and licensed to transport medicines. This is regulated by the Federal Law N61 "On the circulation of medicines" dated 04/12/2010.

Employees of pharmacies and clinics are responsible for the proper storage of antiseptics and medicines. In case of untimely disposal, employees may fall under administrative responsibility. In the case of the sale of deliberately stitched or defective goods, the criminal code comes into force.

How to properly store hydrogen peroxide

This substance is very unstable, and under the influence of third-party factors is destroyed incredibly quickly. Therefore, it is important to store it in the right place and in the appropriate container. Peroxide is sold in dark glass bottles or opaque jars. When storing it, two points should be taken into account:

1. The storage temperature does not exceed 23 degrees.
2. Lighting should be minimal, without direct sunlight.

If these conditions are not met, then hydrogen peroxide will very quickly become completely unusable. The best place for this substance would be a refrigerator - both dark and cool. When using peroxide, pour it from a container rather than dipping cotton into it. Upon contact with foreign objects, the solution will quickly lose its properties.

When properly stored, hydroperoxide does not lose its properties for three years if the container has not been opened. After opening the vial, the expiration date will be approximately thirty to forty days. And if you have prepared a mixture of peroxide with water for use on the farm, then such a working solution will not lose its bactericidal qualities for just a day.
How to determine if hydrogen peroxide has retained its characteristics? If you doubt the correct content of the container with the solution, then it is better to check and be one hundred percent sure. There is one very easy and fast way to do this. Just pour some liquid from the bottle into the sink. If it hisses, then the expiration date has not yet expired.

Can peroxide be used after the expiration date?

Once the expiration date has passed, the properties that make hydrogen peroxide a good disinfectant are gone. Therefore, there is no benefit in using it. It will not cause harm, but the expected death of infections will not occur.

Hydrogen peroxide should only be used externally. In recent years, the idea has emerged that this solution, when taken orally, has healing properties. But this is not subject to official medicine. Thus, you can only hurt yourself. Remember that peroxide, even at low concentrations, is considered a strong oxidizing agent. Use with caution, avoid contact with eyes and mucous membranes. And if you find an expired bottle in your first aid kit, it's better to get a new one.

Hydrogen peroxide is a slightly viscous liquid that is colorless and odorless. In medicine, this substance is used as a disinfectant for the treatment of wounds of various origins. But, like any other medical product, peroxide has its own expiration date, which should certainly be taken into account when using it.

Hydrogen peroxide expiration date

The shelf life of hydrogen peroxide 3% depends on the method of its production, that is, factory or pharmacy. When manufactured at the factory, the shelf life of hydrogen peroxide is 2 years, and at the pharmacy - 15 days, according to clause 161 of Appendix 2 of the order of the Ministry of Health of the Russian Federation dated July 16, 1997 No. 214 "On quality control of medicines manufactured in pharmacy organizations (pharmacies)"

The expiration date of hydrogen peroxide must be indicated on the packaging of the drug:

• A solution of 6% is stored in a dark place in a closed package at temperatures up to +25 degrees Celsius for 2 years
• Once opened, this solution will keep for 12 months.
• Peroxide working solution should be used within 48 hours

Hydrogen peroxide expiration date after opening

There is no regulatory documentation according to which it is possible to determine the shelf life of hydrogen peroxide after opening the package. But you must always remember that in an open vial, the active substance of the drug loses its properties, and thus hydrogen peroxide reduces its antiseptic effect.

In order to reduce the loss of the antiseptic effect, it is recommended to pack the drug in smaller containers at. It is also important to control the amount of the drug that is part of the drug. These requirements are approved by the order of the Ministry of Health of the Russian Federation dated July 16, 1997 No. 214.

Features of hydrogen peroxide:

1. Keeps bactericidal properties at freezing with the subsequent thawing.
2. The tool can be transported using any type of transport, subject to the temperature regime from -30 degrees Celsius to +30 degrees Celsius.
3. It is a safe disinfectant, which belongs to the IV class of low-toxic substances, the decomposition of which occurs during contact with air. This releases oxygen.
4. The bactericidal effect is achieved due to the formation of an intermediate product, namely the active hydroxyl radical.
5. The activity of the drug is aimed at the cytoplasmic membrane of bacteria and spore membranes, the oxidation of enzymes, proteins and peptides. This process is accompanied by lysis of microorganisms.
6. It is effective to use a solution of 6% hydrogen peroxide to disinfect contaminated surfaces with gram-positive and gram-negative bacteria, as well as mycobacteria, helminths, protozoa, tuberculosis pathogens, pathogenic fungi and viruses.
7. Disinfects the premises from the main protozoa, which are the source of candidiasis, dermatophytosis and conidia of pathogenic fungi that live in humid air.

and objects is carried out according to a special regime:

To learn more about this technique, you should refer to the document: "Guidelines for disinfection, pre-sterilization cleaning and sterilization of medical devices" (No. MU-287-113, approved by the Ministry of Health of the Russian Federation on December 30, 1998). Repeated disinfectant solutions must not be used.

For this, aerosol generators are used, on which special modes are set, which are prescribed in the relevant instructions for use.

• Walls, floors, furniture and other surfaces in the room are treated using rags that are moistened in a peroxide solution or irrigation is carried out from a hydro-panel or other sprayer.
• In the same way, they irrigate and wipe sanitary vehicles.
• Disinfection of linen is carried out at the rate of 4 liters of the product per kilogram of linen. After that, the linen is washed and rinsed with clean water.
• Dining and laboratory glassware is immersed in the solution at the rate of 2 liters of product per 1 set of dishes. After that, the dishes are washed with clean running water.
• Various patient care items, as well as toys, are disinfected with a rag soaked in a peroxide solution. Small objects are completely immersed in the solution, while large objects can be treated by irrigation. The final step is to rinse the items with water.
• Medical items are processed by complete immersion in the working solution. In this case, it is necessary to achieve complete filling of all cavities using a pipette or syringe. If the product can be disassembled into smaller parts, then this must be done. The solution layer above the objects should be at least 1 centimeter. After the end of the procedure, the items are thoroughly rinsed with running water:
  • when treated with a 3% peroxide solution - at least 3 minutes;
  • when treated with a 4-6% peroxide solution - at least 5 minutes;
  Dental impressions are disinfected by complete immersion in the working solution, while adhering to the modes suggested by the instructions. When finished, the impressions are washed with water.

Hydrogen peroxide(or hydrogen peroxide H2O2) is one of the most environmentally friendly substances that are widely used due to their unique properties.

Its scope includes oxidative reactions and bleaching processes, purification of exhaust air and drains, disinfection.

The power of matter lies in extra oxygen atom attached to water in several ways.

Is there an expiration date?

Peroxide and more concentrated perhydrol quite easily enter into chemical reactions that cause them to decompose, so they have have an expiration date.

This is perhaps the only disinfectant that is distinguished by the simplicity of its composition - only oxygen and water.

The shelf life of a 3% solution depends on whether the product is manufactured industrially or in.

Product suitability kept for use:

• in factory production- 2 years;
• in pharmaceutical preparation- only 15 days (according to the order of the Ministry of Health of the Russian Federation of July 16, 1997 No. 214).

Hydrogen peroxide solution 3% and 6% stored according to GOST 177-88:

1. unpacked- 2 years;
2. unpacked– maximum 1 month;
3. working solution recommended for use no later than 24-48 hours.

Perhydrol (30-40%) is a fairly strong and dangerous oxidizing agent, especially if it is not diluted. According to GOST 10929-76, perhydrol should be used for a maximum of six months from the date of manufacture, and the use of working solutions is given no more than one day.

Storage Features

For hydrogen peroxide, and even more so perhydrol, it is of no small importance in what containers it is stored.

The most suitable storage option is original containers from tinted glass or opaque plastic bottles.

The main factor influencing storage is the property of a substance to easily decompose into water and gaseous oxygen.

In this regard, the capacity of over 200 ml cannot be hermetically sealed.

Suitable for storage where cool and dark and no ultraviolet radiation.

Solution 3% and 6%

A medical solution, which is certainly found in every first aid kit, requires, first of all, darkness and temperature, not exceeding +23°C.

In any case, it is preferable to store the medication in the refrigerator, especially the already opened vial.

After opening, the duration of storage does not exceed 30-45 days. Interaction with foreign objects, as well as with oxygen, is fraught with the development of chemical reactions, which quickly leads hydrogen peroxide to an unusable state.

Perhydrol 33% and 38%

High reactivity does not prevent perhydrol from maintaining a long chemical stability.

This is the key to its stable storage throughout several years if the conditions of its maintenance meet the requirements.

Among the factors, contributing to the acceleration of the process of chemical decomposition of perhydrol, stand out such as:

• impact high temperature;
• hit sunlight, especially direct;
• elevated pH value;
• presence in it impurities, especially salts formed by transition metals.

Perhydrol is a highly hazardous substance that can cause serious damage to the eyes, skin and respiratory tract!

When using it, you should take care in advance about security measures- Protective masks and gloves.

When ingested deadly it is customary to consider a dose of 50-100 ml of 30% perhydrol. A concentrated solution can cause detonation.

It is better to store it in original packaging, excluding the placement of foreign objects in the container, in order to avoid contamination with all the ensuing consequences.

He will familiarize you with the permissible storage period for levomekol.

Suitability test

Even if the container is closed, there is still a slight flatulence, indicating decay processes.

The only difference is that the degree of intensity of this process much less than in contact with a wound or other surface.

To check the suitability of H2O2, it is enough to lightly sprinkle it on a cut of a potato or just in a sink. Hiss solution confirms its suitability for further use.

If bubbles are not observed, then the decomposition process has gone too far and the product in the bottle is hopelessly spoiled.

The danger of an expired solution

The delay does not pose a particular danger, it is rather about meaninglessness the use of such a tool if necessary, since almost all bactericidal properties are irretrievably lost. What is the point of treating the wound with an absolutely useless liquid?

If you find peroxide in your first aid kit, which has spent a lot of time there, it’s better first check date its production, and then tested for suitability.

Maybe it's time to buy new packaging medical product.

Does he exist?

Does hydrogen peroxide have an expiration date?

Hydrogen peroxide is available to the consumer in pharmacies as a 3 or 5 percent aqueous solution.

This is, in fact, the only disinfectant consisting exclusively of water and oxygen.

Hydrogen peroxide is often regarded as the true "green chemical". When H2O2 reacts with organic material, it breaks down into oxygen and water, which is not toxic for general use.

Peroxide and more concentrated perhydrol are easily decomposed, therefore they have a certain shelf life, taking into account the impact of external factors on it.

According to GOST

Hydrogen peroxide is found in many households with low concentrations(3-9%) for disinfections and some cosmetic procedures. For medical purposes and industry, perhydrol is used in more than high concentrations(33-38% and more).

Storage Features

The shelf life of hydrogen peroxide is affected by the material from which the container for the content of H2O2 is made.

The product is available in dark glass containers or opaque polyethylene bottles - this the most suitable materials for storage.

The higher the percentage of hydrogen peroxide, the more carefully you need to consider the storage conditions of the product.

The property of a substance to decompose in the presence of certain active impurities, with the formation of gaseous oxygen and water, is an important factor for proper storage funds.

Peroxide should be stored in a dark, cool place, protected from UV rays. A container of more than two hundred milliliters is not hermetically clogged.

3% and 6% solution

Hydrogen peroxide, which is in almost every home first aid kit, should be kept in a dark place, at a temperature no higher than 23 degrees. Sealed peroxide is best stored in the refrigerator, including an already opened bottle.

From the moment the container with the solution is opened, the peroxide is good for another 30-45 days.

Do not contaminate the solution by dropping the soiled swabs into the container. Upon contact with foreign objects, as well as upon reaction with oxygen, the peroxide will begin to decompose, and will soon be completely useless for further use.

33% and 38% perhydrol

Despite its high reactivity, perhydrol is a stable substance, and when kept under optimal conditions, can be stored for many years.

The most important factors increasing the rate of decomposition, are:

• high pH value;
• high temperatures;
• direct sunlight;
• the presence of transition metal salts and all kinds of impurities.

Perhydrol - very powerful oxidizing agent and if mishandled can be severely corrosive to the skin, eyes and respiratory tract. Hydrogen peroxide must be protected from all types of contamination.

1. Perhydrol is kept in the original container. It is not allowed to put anything inside the container with the solution - this reduces the risk of contamination.
2. The substance is stored in a place protected from light and heat. When stored for a long time in the light, H2O2 decomposes and loses its properties.
3. Perhydrol should keep away from organic compounds, combustible mixtures and heavy metals (iron, copper, manganese, nickel, chromium).
4. When the content of the solution in a refrigerator the container must have a clearly marked label so as not to confuse it with water.

How to check for suitability?

Whether the hydrogen peroxide bottle is open or not, the process of breaking it down into water and oxygen always goes: 2 H 2 O 2 → 2 H 2 O + O 2 (g).

Even in a closed container, the process of gas formation occurs, but the reaction proceeds much more slowly than when the substance comes into contact with a cut or other surface.

Gas formation reactions, that is, the appearance of bubbles, contribute to transition metals such as the presence of iron in the blood.

If you are not completely sure about the suitability of H2O2, there is a safe way to check this. It is enough to sprinkle a little peroxide into the sink or onto a potato slice.

If the solution "hisses", then the product is suitable for further use. There are no bubbles - it's time to replace the bottle.

Not worth it open the container with the substance in advance and pour H2O2 into another container, especially from transparent glass.

Why is it dangerous to use an expired one?

The danger of an expired substance is senselessness of its application.

When a bactericidal agent is urgently needed, and a useless liquid is used instead, then this will not bring any benefit, except harm.

If you find a bottle of peroxide in your first aid kit that has been stored there for a long time, look at date of manufacture and check the substance for suitability. Maybe it's time to replace it?
