Potassium Permanganate Uses

Potassium Permanganate Uses

Potassium Permanganate: Potassium permanganate crystals and concentrated solutions are caustic and can burn the skin. Even fairly dilute solutions can irritate skin and repeated use may cause burns. If redness or irritation continues, notify your doctor. When preparing solutions, make sure that the crystals or tablets are fully dissolved in water before using them.

Potassium permanganate soaks are not suitable for dry skin conditions. Note that potassium permanganate may leave a brown stain on skin and nails as well as the bath or vessel holding the solution. Use nail varnish or by apply soft paraffin to fingernails and toenails before treatment.

Potassium Permanganate Formula

Potassium permanganate, KMnO4, is delivered in crystal form, typically in 25 or 50 kg kegs or 150 kg drums. The crystals do not deteriorate and may be stored indefinitely but should be kept away from organic chemicals such as polymers and activated carbon

The chemical is prepared as a solution of around 4% w/v, usually in batching tanks with mixers. The product is free-flowing, allowing metering conveyors to be used to transfer crystals from a storage hopper to the batching tanks.

The prepared solution is metered to the dosing point using reciprocating diaphragm pumps. The dose rate is normally controlled in direct proportion to flow past the dosing point. Potassium permanganate should not be dosed in the same location as PAC, as the PAC may consume the permanganate (US EPA, 1999), although it can be dosed with coagulants or polyelectrolyte solutions.

Potassium Permanganate Boiling Point

Potassium Permanganate Boiling Point

Potassium permanganate is a powerful oxidizing agent, that is, it will initiate a fire or explosion if brought into contact with reducing materials, combustibles, organic materials; strong acids; or oxidizable solid, liquid, or gas; glycerine, ethylene glycol, polypropylene, hydroxylamine, hydrogen trisulfide, antimony, arsenic, sulfuric acid, hydrogen peroxide, phosphorus, and any finely divided combustible material. It will decompose, and release oxygen if brought into contact with heat, alcohol, acids, ferrous salts, iodides and oxalates.

In nonpolar solvents addition of oxidants to Bchl does not result in the formation of the second type of spectrum. After the addition of oxidants, the Bchl+ intermediate in acetone lacks a marked 520 mμ band but retains the band at 900 mμ.

Besides being oxidized, Bchl can be reduced in air-free pyridine in the presence of a suitable electron donor (e.g., ascorbic acid) and light (52). The reduced compound shows a band at about 660 mμ (53). No mention is made of a band in the reduced compound on the longwave side of the 770 mμ Bchl bands.

Pekkarinen and Lipschitz (22) measured the absorption spectrum of a metastable, probably triplet, state of Bchl obtained with brief flashes (10−5sec) of high-intensity light. The absorption spectrum (in air-free pyridine) shows a Soret band at about 400mμ and a broad plateau from about 500 to 650 mμ. No measurable band was found in the 900 mμ regions.

Where To Buy Potassium Permanganate

What does the procedure involve?

The solution should be prepared freshly just before use as if left it will start to oxidize and go brown. Use a clean container lined with a clean white bin liner bag. Fill with 4 liters of warm tap water and add one (Permitabs) tablet (wearing gloves) and allow to dissolve completely. The water should be light pink colored. If treating hands and feet, apply vaseline to the nails to prevent staining. If recommended for the limbs, then immerse the area to be treated. Occasionally it may be recommended that you soak some gauze swabs with the diluted solution and apply the damp swabs to the weeping areas of skin for example under the breasts or in the groin. Soak affected areas for 10-15 minutes and then pat dry. Discard the solution and clean container thoroughly after use.

How should the treated area be cared for?

Once the affected area has been soaked and dried apply any prescribed cream/ointment and or dressings, and repeat as recommended by your healthcare professional.

What are the possible side effects of potassium permanganate soaks?

  • Can cause irritation if the dilution is not adequate.
  • Contact with eyes and mucous membranes (inside of mouth, nose, ear, genitals and anus) may cause irritation and should be avoided.
  • Harmful when swallowed – eating and drinking should be avoided when using the product.
  • Dryness.
  • Permitab is a dye and will stain clothing, fabrics and ceramic basins.
  • Can cause burns.

How will I be monitored for the side effects of potassium permanganate soaks? 

The nurse administering the treatment will assess your skin prior to and post-treatment. If you are treating yourself and you have concerns, contact the healthcare professional who prescribed the treatment. If you accidentally swallow the tablet or solution drink plenty of water, do not induce vomiting and seek immediate medical help.

What is potassium permanganate?

Potassium permanganate is a common chemical compound that combines manganese oxide ore with potassium hydroxide.

It was first developed as a disinfectant in 1857. Since then, it’s been widely used to treat a variety of skin conditions, including fungal infections. In many countries, including the United States, you’ll need a prescription from your doctor to receive potassium permanganate.

Keep reading to learn more about its medical uses and safety tips.

What does it treat?

When applied to your skin, potassium permanganate kills germs by releasing oxygen when it meets compounds in your skin. It also acts as an astringent, which is a drying agent.

Some of the conditions that potassium permanganate can help treat include:

  • Infected eczemaIf you have eczema with blisters, potassium permanganate can help to dry them out.
  • Open and blistering wounds. Potassium permanganate is used as a wet dressing for wounds on your skin’s surface that are blistered or oozing pus.
  • Athlete’s foot and impetigo. Potassium permanganate can help to treat both bacterial and fungal skin infections such as athlete’s foot and impetigo.

How do I use it?

Before applying potassium permanganate to your skin, it’s important to dilute it with water. Most medical users require a dilution of 1 part to 10 when using a 0.1% potassium permanganate solution.

To achieve an appropriate dilution using potassium permanganate 0.1% solution, combine 1 part potassium permanganate with 10 parts hot water. Undiluted potassium permanganate has a striking purple color, but a diluted solution should be pink.

Potassium permanganate must be diluted since the undiluted solution may cause burns. Even with dilution, it may irritate the skin, and with repeated use may still cause burns.

Potassium permanganate also comes in 400-milligram (mg) tablets. To utilize the tablets in a bath soak, dissolve 1 tablet in 4 liters of hot water before pouring into the bath. The bath soak may be repeated twice daily for two days.

Here are some guidelines on how to use potassium permanganate for specific conditions:

  • Infected eczema. Use or create a dilution of 1 part in 10,000. Add it to a basin or bathtub and soak the affected part of your body.
  • Superficial wounds. Apply a dilution of 1 part in 10,000 to a bandage and apply it over your wound. Change the bandage two to three times a day.
  • Athlete’s foot. For severe infections, soak your foot in a 1 part in 10,000 dilutions of potassium permanganate every eight hours. Depending on how severe your infection is, your doctor might prescribe a stronger solution.
  • Impetigo. Gently rub a dilution of 1 part in 10,000 on the affected skin to removed loose bits of skin.

Depending on your condition, your doctor might instruct you to create a stronger solution with a dilution of 1 part in 7,000. To achieve this, mix 1 part potassium permanganate with 7 parts hot water. This will create a slightly darker pink liquid.

Are there any side effects?

Potassium permanganate is generally safe, but it may leave a brown stain on your skin and nails, which should fade after a day or two. It might also leave a stain in your bathtub that’s hard to remove, which is why many people prefer to use it in a smaller basin.

Adverse side effects include skin irritation, redness, or burns

Potassium permanganate is a powerful solution that must be diluted before applying it to your skin. If it’s not diluted, it can damage your skin as well as the mucous membranes of your nose, eyes, throat, anus, and genitals.

Avoid using it near your eyes, and make sure you don’t swallow any, even in its diluted form.

For added safety, make sure you wear gloves when you’re preparing a dilution. If you’re using potassium permanganate tablets or crystals, make sure they’re fully dissolved in water before using the solution. Using hot (not boiling) water will help them dissolve.
