How to wash off iodine on skin

When our soft tissue is bruised, iodine will be used. As we all know, iodine is a drug that can disinfect and reduce inflammation. Using iodine on some wounds can effectively prevent bacterial growth. But everyone also knows that because of the production process of iodine, it will leave some color when applied to the skin. So, how do you wash iodine off your skin?

Iodine and starch can interact with each other. That is to add some water to starch at home, stir it thoroughly, and then apply it on the part of the face where iodine is present. It will take effect in about 20 minutes.

Precautions

1. Do not use iodine tincture on a large area to prevent iodine poisoning due to absorption of large amounts of iodine.

2. Generally, it is not used on ulcerated skin.

3. It is forbidden for people who are allergic to iodine.

4. Iodine tincture should not be applied at the same time as mercurochrome (commonly known as red medicine) to avoid the production of mercuric iodide and skin corrosion.

5. Iodine tincture, also known as iodine tincture, is an external disinfectant that many households have on hand. Iodine tincture contains iodine, potassium iodide and dilute ethanol solution. It has a strong effect in killing bacteria and molds, and can kill spores. Potassium iodide acts as a solubilizing agent in iodine tincture, but if it is left for too long, iodine will react with the water to produce iodonic acid and hypoiodous acid. The latter can further oxidize ethanol to produce acetaldehyde and acetic acid. At this time, due to the reduction of free iodine content, the bactericidal power decreases, and the irritating products increase, which will enhance irritation to the skin. Therefore, iodine tincture should not be stored for too long.

6. The normal appearance of iodine tincture should be a reddish-brown clear liquid with the distinctive smell of iodine and ethanol. If iodine tincture evaporates severely and is no longer reddish-brown, it cannot be used for medicinal purposes. Iodine should be stored in a brown glass bottle in a sealed, dark place. Do not use rubber, cork or metal stoppers because these substances can react chemically with iodine and weaken its bactericidal effect.
