Shelf life of potassium permanganate (potassium permanganate)

Does potassium permanganate have an expiration (storage) date?

Potassium permanganate, better known as potassium permanganate, is probably in every first aid kit.

This is a well-known antiseptic used for burns and open wounds, and is also used as an emetic.

It is believed that the shelf life of potassium permanganate in a dry state is unlimited and it does not require special storage conditions. Is it really durable and under what conditions does it retain its medicinal properties?

General characteristics

This medicine is a dark purple crystalline powder. Upon contact with water it acquires a crimson hue. It is used for both medical and household purposes.

For rinsing the mouth during inflammatory processes.
For disinfection of abrasions, ulcers and burns.
For gastric lavage in case of poisoning and toxic infections.
As an antiseptic for hygienic care of the organs of vision and skin.
For gynecological and urological douching.
To assess water quality.
As a detergent to remove organic compounds such as fats.
When tinting photographs.
To determine the mass fraction of sugar in confectionery and bakery production.
Reagent for the determination of sucrose and potassium iodide.

Side effects and overdose

Potassium permanganate in some cases causes allergic reactions, and upon contact with the skin - redness and burns. Contraindicated for use in people with individual hypersensitivity to the drug.

An overdose when used orally is accompanied by sharp pain directed down the esophagus. The mucous membrane of the oral cavity turns red and swells noticeably. Swelling of the larynx may develop, which in turn leads to mechanical asphyxia.

With low acidity, methemoglobinemia is possible, which is accompanied by severe shortness of breath.

Symptoms of overdose are: hemorrhagic colitis, manifestations of Parkinson's disease, convulsions and increased muscle excitation, nephropathy and hepatopathy, burn shock.

Release form

It is mainly sold in pharmacies in powder form, packaged in glass jars or thick bags made of special paper. Sometimes you can find a larger crystalline substance.

Previously, a ready-made 5% solution was available for sale. But currently the production of liquid permanganate is prohibited.

Shelf life of potassium permanganate

The legislation of the Russian Federation establishes that all chemical compounds used for medical purposes have a certain shelf life, after which their further use is not recommended. And manganese is no exception.

Potassium permanganate, used for medical purposes, can be guaranteed to be stored for up to three years from the date of manufacture, according to GOST 20491-75. Technical product used in agriculture and other industries - up to one year in accordance with GOST 57774-84.

However, manufacturers indicate a shelf life on packaging with dry substances of five years. With longer use, the chemical loses its medicinal properties and becomes useless.

The main indicator is that it ceases to dissolve in water. If you managed to prepare a solution from a 25-year-old powder, you can safely use it.

The main thing is that its color is pinkish or crimson, and not red-brown.

Important! Crystals of the substance are stored as long as potassium permanganate in powder.

The solution has a limited shelf life. It is not recommended to prepare it “for the future.” The 5% solution is suitable for use within just two days from the date of manufacture.

Storage rules

Manganese dust has a toxic effect on the human body. Therefore, it is important to observe certain storage intervals for the drug.

Store in a tightly closed glass container.
Prevent exposure to sunlight.
Keep out of the reach of children, as contact of the concentrated substance with the mucous membrane and skin can lead to burns.
Do not expose to high temperatures. When heated to 240°C, the chemical decomposes, releasing oxygen.
Keep away from various oils and fats, glycerin, phosphorus and sulfur as this may cause fire or explosion.
The compound of manganese with active metals such as aluminum, magnesium, calcium, etc. is explosive both under normal conditions and at elevated temperatures.
The solution remaining after use must be discarded. Rinse the container in which it was located with running water without using detergents that contain glycerin and various fats.

How to properly store at home?

The drug in crystals could be stored for 3 years. It was used in everyday life as an antiseptic for washing wounds, eliminating the consequences of poisoning by inducing vomiting, and preventing intestinal infections. Technical potassium permanganate was supposed to be stored for no more than a year.

How to determine whether potassium permanganate is suitable for use? Very simple. If it has acquired a brown tint, then it’s time to get rid of it. Potassium permanganate in optimal condition has a pink (to raspberry) tint. We diluted potassium permanganate and it was light pink, but after 5 days the solution darkened and acquired a dirty pink color - this means that it has deteriorated. Many people add potassium permanganate when bathing newborn children. Whether to do this or not, watch the video.

Potassium permanganate, better known in everyday life as potassium permanganate, is a potassium salt that is widely used in medicine as an antiseptic for washing wounds, burns, gargling, and also as an emetic.

Is there an expiration date and what is indicated in GOST?

Potassium permanganate has a shelf life. Russian legislation establishes that, according to Article 58 of the Federal Law of April 12, 2010 No. 61 “On the circulation of medicines,” any chemicals used in medicine must have certain expiration dates. After the last one has expired, it is not recommended to use the chemical.

According to GOST 20490-75, which is called “Reagents. Potassium permanganate. Technical Specifications” was compiled back in the days of the USSR and contains changes made to it in 2020, this period on average is exactly 3 years from the date of manufacture of potassium permanganate. However, it is necessary to take into account the exact form in which it is presented and, when calculating the shelf life, build on it.

What is the storage time for different types?

Today, many people use potassium permanganate in everyday life, which they received from their grandmother, and think that after such a long time it has not yet lost its abilities. However, this is not the case. Let us consider the main states in which potassium permanganate can be present.

Powder

In powder form, the shelf life of potassium permanganate is 5 years from the date of production. But it must be remembered that in this case it must be stored at a temperature no higher than 25°C.

Therefore, if for some reason potassium permanganate is lying around in the first aid kit from the times of the USSR, then it is worth checking it first with a solution. Also, to preserve the beneficial properties of the powder, you need to protect it from water.

These crystals are those chemicals that are stored with the utmost care. This potassium permanganate is stored for 5 years. Exactly the same as powder.

Diluted solution

According to the state standard, potassium permanganate should not be allowed to be stored for a long time in the form of a solution, because it in no way applies to long-term storage medications - maximum 1-2 days.

In order for this solution in the form of a solution to exhibit all its chemical properties, it must be fresh.

After using it, the container in which it was located is thoroughly washed with running water without the use of detergents or soap.

What determines the period of suitability?

There are a number of factors that can affect the quality of potassium permanganate during storage:

Firstly, in what form the product is stored - this was discussed above.
Secondly, from the storage location.
Thirdly, on the handling of potassium permanganate and the room temperature.

Therefore, under any circumstances, you need to pay special attention to the conditions of its storage, because even in a normal environment it can be explosive.

Storage conditions

A person must follow certain storage rules, because... manganese dust is toxic to his body.

Due to the fact that potassium permanganate is explosive, the supply to some pharmacies has stopped, but others follow strict rules regarding its sale and storage:

The pharmacy must be specially equipped to safely store this flammable substance. For example, have continuous supply and exhaust ventilation.
Various tests of potassium permanganate in pharmacies (for example, weighing) should be carried out in the laboratory in a fume hood.
The temperature should not rise above 25°C. When heated to 240°C, this chemical decomposes and begins to release oxygen.
Keeping strict records of the consumption and receipt of potassium permanganate.
Potassium permanganate is stored away from active metals: aluminum and magnesium. When they interact with it, an explosion may occur.

Many pharmacies refuse to sell potassium permanganate due to its expensive content. Few of them can afford expensive special lockers. In addition, the product itself is too cheap and does not pay for this kind of expense.

Basic conditions for storing potassium permanganate at home:

In a dark place, out of reach of children, where the sun's rays do not penetrate. It must be remembered that if it gets on the mucous membrane or skin, it can cause severe burns to the mucous membranes of the nasopharynx, throat and eyes. A closed glass container is best for storing this product.
When using the drug, it is necessary to observe the rules of personal hygiene, as well as personal protective equipment.
Potassium permanganate must not be stored together with various oils and fats, glycerin, sulfur, phosphorus, heating devices and active metals. Such proximity usually leads to a fire or explosion.
After using a 5% solution, it must be thrown away, because The shelf life of potassium permanganate in this form does not exceed 2 days.

How to identify a low-quality drug?

As mentioned above, during long-term storage, potassium permanganate loses its properties and becomes unusable. But what happens to it after the expiration date and how to determine whether it can still be used or not? If potassium permanganate comes into contact with water or hot air, then it loses its own chemical properties as an oxidizing agent and becomes useless.

Potassium permanganate in the form of a solution or powder also has several signs that indicate its deterioration and unsuitability:

A certain proportion of crystals cease to dissolve in water, resulting in a crystalline precipitate.
If the 5% solution comes out not crimson or pink, but red-brown, then under no circumstances can it be used.

Be sure to follow the expiration date indicated on the packaging and follow the storage rules. If everything is done correctly, potassium permanganate will retain its chemical qualities for a long time.

In order to determine whether potassium permanganate is suitable for consumption or not, you just need to turn to the laws of chemistry and prepare a solution from it.

According to similar laws, manganese loses its oxidizing properties if stored improperly, even if all expiration dates are met.

Also, if you manage to dissolve potassium permanganate, which is more than 5 years old, without signs of deterioration, then you can still safely use it.

Potassium permanganate is a unique remedy that, if all storage rules are followed, will come to the rescue at any time. If you have the slightest doubt, you can check it in advance by turning the powder or crystal into a solution. If everything is in order, then you can use it without fear.
