Product Description
Tannic Acid, also known as tannin or gallotannic acid, is a type of polyphenol belonging to the tannin family. It is a water-soluble compound with the chemical formula C₇₆H₅₂O₄₆, typically extracted from natural sources such as oak galls, tea leaves, or nutgalls. Historically used in traditional medicine and industry, Tannic Acid exhibits strong astringent properties due to its ability to bind proteins and other macromolecules.

Q: What is Tannic Acid used for?
A: Tannic Acid is primarily used as an astringent in pharmaceuticals, a clarifying agent in beverages, and a tanning agent in leather production. It also serves as an antioxidant in cosmetics and a mordant in dyeing processes.
Q: Is Tannic Acid safe for human consumption?
A: Yes, when used in approved amounts. It is GRAS-listed by the FDA for food applications, but excessive intake can cause gastrointestinal issues.
Q: What are the differences between Tannic Acid and other tannins?
A: Tannic Acid is a specific hydrolyzable tannin, while others like condensed tannins (proanthocyanidins) are non-hydrolyzable. Tannic Acid breaks down into gallic acid and glucose, offering unique binding properties.
Q: Can Tannic Acid be used for skin treatments?
A: Tannic Acid is indicated for topical applications such as treating cold sores, diaper rash, and minor burns due to its astringent and protective properties.
Q: How should Tannic Acid be stored?
A: Store in airtight containers in a cool, dry, dark place to prevent oxidation and color change.
