Product Description:
Tannic acid is widely used in the food and beverage industry as a clarifying agent, particularly in the production of beer and wine. It helps remove impurities and improves the clarity and stability of the final product. In the medical field, it is applied as an astringent to treat minor burns, cuts, and skin irritations due to its ability to constrict tissues and reduce bleeding. It is also utilized in the leather industry for tanning hides, where it binds to proteins in animal skins to create durable and flexible leather. Additionally, tannic acid serves as a natural dye in textiles and as a mordant to fix dyes onto fabrics. In water treatment, it is used to remove heavy metals by forming insoluble complexes, aiding in purification processes. Its antioxidant properties make it valuable in cosmetic formulations to protect skin from oxidative stress.
