Tannic acid is in a class of chemicals called tannins, which are found in many plants. Tannic acid refers to tannins that can be dissolved in water, as opposed to the other type, or condensed tannins.According to Cornell University Department of Animal Science, tannins are a group of compounds known as plant polyphenols, which cause proteins to bind and form complexes. Tannins are found in many of the foods you eat, including fruits, teas, wine and edible grasses.

Industry grade:
Clarifiers, astringents, crude deodorizers, and fragrance aids; Tannic acid can be used in tanning, ink manufacturing, paper and silk gluing, boiler descaling, etc. It can also be used as a mordant, a clarifying agent for beer and wine, and a coagulant for rubber. Tannic acid can be used in industries such as printing and dyeing, metallurgy, and pharmaceuticals, with low inherent toxicity. Precipitation and weight determination of beryllium, aluminum, indium, niobium, tantalum, and zirconium. Quantitative determination of copper, iron, vanadium, and cobalt. A precipitant for proteins and alkaloids. External indicator for ammonium molybdate titration of lead. Dye mordant.

Function:
1. With the function of antioxidant and antimicrobial;
2. It has the effect on improving the body disease-resistant ability, liver and gastrointestinal system function
3. With the function of treating chronic diarrhea and dysentery;
4. With the function of dispelling heat, eliminating irritability, diuretic, cooling blood and detoxification;
5. With the function of enhancing immunity.

Application:

1. In the industry, it is used as a raw material for preparing citric acid, pyrogallol and sulfonamides.

2. It has been used in for the treatment of pharyngitis, tonsillitis, acne and skin blisters. It can be used for diarrhea and enterorrhagid.

3. Precipitatingwith metals, alkaloids and glycosidesanddetoxifyingthese substances.

4. Used in tanning, ink manufacturing, paper and silk gluing, boiler anti-scaling, etc.

5. Used as a mordant, a clearing agent for beer and wine, a coagulant for rubber, a reagent for measuring metals such as bismuth, aluminum, nickel, and copper.

6. Used to prepare gallic acid and pyrogallic acid.

7. Used as a dilution when handling drill collar mud.
Also:
1. It can be used as food antioxidant. It is generally mixed with vitamin E, vitamin C or gallic acid before use.
2. Tannin is used as a viscosity reducer and fluid loss reducer for water-based drilling fluids, which can improve the quality of filter cake. It is also used for tanning raw hides and turning them into leather. Tannin has the activity of reacting with proteins, polysaccharides, alkaloids, microorganisms, enzymes, and metal ions, and has the properties of anti-oxidation, capturing free radicals, bacteriostasis, and derivatization reactions. It is more and more widely used in food processing, fruit and vegetable processing, storage, cosmetics, medicine and water treatment.
3. Tannic acid can combine with protein to produce water-insoluble tannic acid protein, so adding it to shampoo can prevent the dissolution of hair fiber protein and protect the hair, and when used in nail products, it can increase nail strength. Gallic tannic acid and isogallic tannic acid have a strong free radical scavenging effect, and their effects are similar to those of gallic acid and catechin compounds. They can be used in skin care products for sun protection and skin lightening. Tannic acid has astringent and antibacterial properties. It is clinically used to treat local bleeding, and can be used for toothpaste to protect teeth and prevent gum bleeding.
4. Mainly used in medicine, ink, printing and dyeing, leather and metallurgy industries and water treatment. Tannin has the functions of flocculation, deoxidation, scale inhibition and sterilization in the water treatment process. Because there are a large number of hydroxyl groups and carboxyl groups produced by partial hydrolysis in the molecular structure, it forms complexes with calcium and magnesium ions in the water to prevent calcium and magnesium ions in the boiler water from forming scale, and can also reduce the deposition of calcium sulfate in the cooling water. , Play a decentralized role. In addition, the cohesive force of tannins can aggregate the sediment into slag, which is discharged out of the boiler and cooling water system through sewage.
5. It can be used as a clarifying agent for low-alcohol wine and fruit wine. It can also be used as a leather tanning agent.
6. Tannic acid is used for chromium-free passivation of galvanized layer.
