Ice acetic acid, also known as acetic acid solution, has the following uses and functions:

1. * * Pharmaceutical field * *:

-* * Treatment of fungal infection * *: It has antifungal effect and is often used to treat infectious diseases caused by fungi, such as onychomycosis (onychomycosis). Generally, a 30% solution of glacial acetic acid is used. Before use, the affected nails should be cleaned and thinned to allow the medication to work better. However, care should be taken to avoid contact with normal skin around the nails.

-* * Relieve skin symptoms * *: Can be used to relieve skin itching caused by insect bites or plant contact, as well as treat some skin surface inflammations such as dermatitis.

-* * Adjuvant treatment for other diseases * *: In the adjuvant treatment of some diseases, glacial acetic acid can regulate the local acidity and alkalinity, change the living environment of pathogens, and thus play a certain therapeutic role. For example, in the treatment of certain gynecological diseases, glacial acetic acid solution may be used for vaginal flushing.

2. * * Chemical industry * *:

-Production of organic compounds: It is an important raw material for the synthesis of various organic compounds such as vinyl acetate, acetic anhydride, and acetate. These compounds are widely used in industries such as plastics, rubber, fibers, coatings, etc.

-Industrial solvent: Due to its ability to be miscible with various solvents such as water, ethanol, and ether, glacial acetic acid can be used as an industrial solvent to dissolve and dilute other substances. It is widely used in industries such as paint, coatings, and inks.

-* * Production of synthetic leather * *: In the production process of synthetic leather, acetic acid can be used as an additive to adjust the acidity and alkalinity of the reaction system and promote the progress of the reaction, thereby improving the quality and performance of synthetic leather.

3. * * Food Industry * *:

-* * Sour flavor agent * *: It can be added to food as a sour flavor agent to regulate the taste and flavor of food. For example, in the production of tomato sauce, mayonnaise, kimchi, cheese and other foods, glacial acetic acid can increase the acidity of the food, making its taste more delicious.

-Fragrance enhancer: It can enhance the aroma of food and work synergistically with other spices to make the aroma of food more intense. In some candies, baked goods, pudding and other foods, glacial acetic acid can be used as a flavoring agent.

-Food processing aids: During the food processing, glacial acetic acid can be used to clean equipment, pipelines, etc., playing a role in disinfection and sterilization.

4. * * Beauty and skincare field * *:

-* * Keratin softener * *: can soften and dissolve the stratum corneum, used for foot exfoliation, nail trimming, etc. In some cosmetics and skincare products, an appropriate amount of glacial acetic acid is also added to achieve the effect of removing keratin and improving skin texture.

-Adjusting the pH value of the skin: The pH value of healthy skin is weakly acidic, and glacial acetic acid can help regulate the pH value of the skin, keeping it within the normal range, thereby enhancing the skin's barrier function and preventing the occurrence of skin diseases.

5. * * Other fields * *:

-In the printing and dyeing industry, acetic acid can be used as a dyeing aid and neutralizing agent. It can help dyes adhere better to fibers, improve dyeing effectiveness and color fastness; At the same time, it can also neutralize alkaline substances generated during the printing and dyeing process, maintaining the pH stability of the printing and dyeing solution.

-* * Laboratory reagents * *: are commonly used reagents in laboratories for chemical analysis, synthetic reactions, etc. For example, in acid-base titration experiments, glacial acetic acid can be used as a standard solution; In organic synthesis experiments, glacial acetic acid can be used as a reaction solvent or catalyst.
