Tannic acid, a specific form of tannin, is a polyphenolic compound derived from natural sources such as gallnuts. As a versatile chemical intermediate, it is widely utilized in the food and beverage industry for clarification, in pharmaceuticals for its astringent properties, and in industrial sectors for leather tanning and textile dyeing. At GetChem, we provide high-quality Tannic Acid with rigorous quality control to meet global standards.
Food & Beverage: Used as a clarifying agent for beer, wine, and juices. It also acts as a natural flavor enhancer and antioxidant.
Pharmaceuticals: Employed in the production of astringent ointments and anti-diarrheal medications due to its protein-precipitating properties.
Industrial / Textile: Essential for leather tanning, as a mordant in dyeing processes, and in the manufacture of gallic acid and pyrogallol.
Water Treatment: Used as a coagulant in specific industrial wastewater treatment processes.
Packaging: 25kg/drum, or customized packaging options according to customer requirements.
Storage: Store in a cool, dry, and well-ventilated area. Keep away from direct sunlight and moisture. Ensure the container is tightly sealed when not in use.
