Product Description

High-Quality Annic Acid Powder for Pharmaceutical and Industrial Use

Tannic acid is a tannin obtained from Chinese gallnut. It is a yellow or light brown light non-crystalline powder or scale; odorless, with a slight special smell and extremely astringent taste. It is soluble in water and ethanol, easily soluble in glycerol. Its aqueous solution turns blue-black when it meets iron salt solution, and adding sodium sulfite can delay the color change. In industry, tannic acid is widely used in tanning leather and making blue ink. Tannic acid can coagulate protein. People use tannic acid to chemically treat raw pig skin and raw cow skin, which can coagulate the soluble protein in the raw skin. As a result, the raw skin that would stink and rot after a few days becomes beautiful, clean, flexible and durable leather. This leather making process is called leather tanning.
