Tannic Acid for Sale: A Complete Buyer’s Guide for Industrial & Food-Grade Sourcing

If you are searching fortannic acid for sale, you are likely a procurement professional, formulator, or researcher looking for a reliable supplier of this versatile polyphenolic compound. Tannic acid (CAS 1401-55-4) is a naturally occurring substance found throughout the plant kingdom, especially abundant in gallnuts, tara pods, and oak species. It is valued across food and beverage, pharmaceutical, nutraceutical, cosmetic, textile, and industrial manufacturing sectors for its strong astringent, antioxidant, and antimicrobial properties, as well as its ability to bind proteins.

This guide explains what tannic acid is, the grades available, key applications, current market pricing, safety considerations, and how to evaluate suppliers.

What Is Tannic Acid?

Tannic acid (also known as gallotannic acid or gallotannin) is a specific form of tannin—a class of polyphenolic compounds that bind to and precipitate proteins. It is a hydrolysable tannin composed of gallic acid esters of glucose. The molecular formula isC76H52O46 with a molecular weight of approximately1701.20.

Tannic acid appears as ayellowish to light brown powder with a slightly special smell and strong astringency. It is freely soluble in water (250 g/L at 20°C), ethanol, acetone, and glycerol, and it decomposes at 210–215°C. Powder Tannic acid for sale.

Grades and Specifications of Tannic Acid

Tannic acid is available in multiple grades to meet different industry requirements. The grade you choose depends on your intended application and required purity level.

Food-grade tannic acid must meet strict purity standards. Taiwan’s FDA requires96% or higher content on a dry weight basis, with acetone and ethanol residues not exceeding 25 mg/kg combined. Pharmaceutical-grade tannic acid is available meetingUSP, Ph Eur, and JP monograph specifications for use in drug manufacturing and quality control.

Key Applications of Tannic Acid

Tannic acid serves diverse functions across numerous industries.

Food and Beverage: Tannic acid is used as aclarifying agent in wine, beer, and fruit juices, where it complexes with haze-forming proteins and metal ions to improve clarity, taste, and shelf life. It also functions as anatural antioxidant, preventing oxidation and extending product shelf life. In brewing, tannic acid solutions help reduce waste, lower costs, and improve antioxidant potential without affecting foam stability.

Pharmaceuticals: Tannic acid is used in the production ofalbumin tannate, which is used as an antihistamine, anti-diarrheal, and anti-tussive agent. It has astringent and antibacterial properties and is clinically used to treat local bleeding.

Industrial Applications: Tannic acid is used in leather tanning,ink manufacture (including blue-black ink),paper sizing, andwater treatment as a flocculant, deoxidizer, scale inhibitor, and sterilizer. It also serves as aviscosity reducer and fluid loss reducer in water-based drilling fluids for oil and gas operations.

Cosmetics and Personal Care: Tannic acid is incorporated into shampoos to prevent hair fiber protein dissolution, into nail products to increase strength, and into skincare formulations for its antioxidant and sun-protective properties. Tannic acid for sale online in USA.
