Tannic Acid Powder: Overview & Applications
Tannic Acid Powder is a polymer composed of gallic acid molecules and glucose. Upon hydrolysis, it breaks down into glucose and either gallic acid or ellagic acid units. Naturally present in nutgalls, tannic acid is commonly applied topically today to address a range of issues: cold sores and fever blisters, diaper rash and prickly heat, poison ivy reactions, ingrown toenails, sore throats, inflamed tonsils, spongy or receding gums, and skin rashes. It also works effectively to stop bleeding.

Tannic acid is a naturally occurring polyphenolic compound extracted from plant sources including gallnuts, tara pods, and oak bark. It appears as a pale yellow to brown powder, boasting astringent qualities and robust antioxidant capabilities. As a versatile multifunctional ingredient, it finds extensive use in the food, cosmetic, and industrial sectors thanks to its binding, stabilizing, and preservative properties. Within the food industry, it serves as a clarifying agent and flavor booster. In cosmetics, it functions as both a skin-conditioning agent and an antioxidant component. For industrial uses, it plays a role in leather tanning, ink production, metal surface treatment, and adhesive manufacturing. Our tannic acid comes in 60% and 96% purity grades, ensuring it meets the diverse formulation needs of various applications.
