It is also a good antimicrobial agent, mainly because it can reduce the pH value below the pH value required for the optimal growth of microorganisms.

Glacial acetic acid is the earliest and most widely used sour agent in China, which is mainly used in compound seasoning, preparation of wax, jelly and so on. When used as seasoning, acetic acid can be diluted into 4%~5% solution by adding water, and then added to various seasonings for use.

It can also be used to treat corns and warts on human body. Before taking the medicine, clean the affected area, soak it in hot water/kloc-0.5 to 30 minutes, apply vaseline to the adjacent normal skin for protection, and then drop the medicine. However, high concentration glacial acetic acid has corrosive effect, and other tinea diseases are not suitable for treatment except onychomycosis.

Although glacial acetic acid can treat onychomycosis, never use this product to treat tinea facialis. The method of treating onychomycosis with glacial acetic acid is to clean the diseased nail and thin it with a blade. Be careful not to touch the nail groove. You can apply a thin layer of vaseline to the skin near your nails for protection.

Extended data:

Acetic acid is widely distributed in nature, such as fruits or vegetable oils, but mainly exists in the form of esters. It exists in animal tissues, excreta and blood in the form of free acid. Many organisms can convert different organic substances into acetic acid by fermentation.

Acetic acid is the main component of vinegar, which almost runs through the whole history of human civilization. Acetic acid fermenting bacteria (Acetobacter) can be found in every corner of the world. Every nation will inevitably find vinegar when making wine-it is the natural product of these alcoholic drinks exposed to the air. In China, for example, there is a saying that Heita, the son of Du Kang, was jealous because he had been brewing for too long.

The ancient Romans cooked sour wine in lead containers and got a kind of syrup with high sweetness, which was called Sapa. Sapa is rich in a sweet lead sugar, namely lead acetate. In the 8th century AD, the Persian alchemist Jaber concentrated acetic acid in vinegar by distillation.

During the Renaissance, glacial acetic acid was prepared by dry distillation of metal acetate. /kloc-Andreas Libavius, a German alchemist in the 6th century, compared the glacial acetic acid produced by this method with the acid extracted from vinegar.

Because of the existence of water, the properties of acetic acid have changed greatly, so that chemists have thought that it is two completely different substances for centuries. Until the French chemist Pierre Adette proved that the main components of these two substances are the same.
