◆ Tannic acid CAS 1401-55-4, 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.
◆ Gallnut is the Rhus chinensis Mill., Rhus potaninii Maxim. or Rhus pun-jabensis Stew.var.sinica (Diels) Rehd. et Wils. The insects on the leaves are mainly gallnuts. Melaphis chinensis (Bell) Baker parasitized. Pick in autumn, boil in boiling water or steam until the surface is gray, kill aphids, remove and dry. According to the shape, it is divided into "Du bei" and "Jiao bei".
◆ Galla chinensis is China's special product and gallic tannins as the major bioactive components have become a hot research in the field of natural products. Studies have showed that gallic tannins have obvious biological activities, such as anti-caries, antimicrobial sterilization, spermicidal, inhibiting mutations, free radical scavenging and antioxidant, etc.

◆ Gallotannic acid can be used for preparation of raw materials for pharmaceutical acid, pyroic acid, sulfonamides. Gallic acid and pyrogallic acid can be produced by chemical production.
◆ Used as a mud treatment agent in the petroleum industry. In addition, it can be used in the production of leather tanning agents, mordants, rubber coagulants, protein agents, alkaloid precipitants, beneficiation inhibitors, alcohol clarifiers, extraction of antimony and preparation of blue-black inks.

◆ In the traditional prescriptions, tannin-based five-branched bitter and catechin tannin-based catechin cream are often used as hemostatic agents on the surface of wounds and burns due to their convergence. Protect wounds and prevent wound infection and inflammation.
◆ Clarifier: It is used to remove turbid protein and other suspended substances in sake, beer, etc., which can solve the non-biological stability of beer, etc., and can reduce acetaldehyde content and extend the shelf life of alcohol.
◆ Astringent: crude oil deodorant; fragrance aid.
◆ Tannic acid can be used in tanning leather, ink manufacturing, paper and silk sizing, aluminum furnace descaling, etc., but also as mordant.
◆ Tannins can also be used in printing and dyeing, metallurgy, and other industries. It has very low toxicity, precipitation and weight determination of beryllium, aluminum, gallium, indium, niobium, and zirconium. Precipitating agent for protein and alkaloid.
