Product Description

Tannic Acid is a naturally occurring polyphenolic compound derived from plant sources such as gallnuts, oak bark, and tara pods. It appears as a light yellow to brown amorphous powder, soluble in water and alcohol, with astringent properties.

In laboratories, Tannic Acid is widely used as a reagent in protein precipitation, metal ion complexation, and histological staining. Industrially, it plays a vital role in leather tanning, ink manufacturing, textile processing, adhesives, and food and beverage clarification. Its antioxidant, antimicrobial, and binding properties make it versatile across scientific, pharmaceutical, and industrial applications.
