Glacial acetic acid with a concentration of more than 10% is corrosive, which can cause skin burns, permanent blindness of eyes and mucosal inflammation, so 30% glacial acetic acid will do harm to human skin and needs proper protection.

Acetic acid chemical formula CH3COOH, also known as acetic acid and glacial acetic acid, is an organic monobasic acid and the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid, which is weakly acidic and corrosive in aqueous solution, so it is harmful to human skin.

The carboxyl hydrogen atom of acetic acid can be partially ionized into hydrogen ions (protons) and released, resulting in the acidity of carboxylic acid. Acetic acid is a weak acid in aqueous solution.

Function:

1, which can be used as acidity regulator, acidulant, curing agent, flavor enhancer, perfume, etc.

2. 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;

3, mainly used in compound seasoning, preparation of wax, canned food, cheese, jelly, etc. When used as seasoning, acetic acid can be diluted into 4%~5% solution by adding water, and then added to various seasonings for use.
