In today’s industrial and consumer sectors, where the demand for green, natural, and efficient raw materials is growing, a powerful natural compound derived from plants is playing an increasingly crucial role. This is tannic acid, a core ingredient with wide applications in food, daily chemicals, pharmaceuticals, and even industrial processing. Unilong Industry Co., Ltd., with its advanced processes and rigorous quality control, is committed to providing high-purity, high-quality tannic acid products to meet the diverse needs of its global customers.

I.Product Introduction: In-depth Analysis of the Exceptional Value of Unilong Tannins

Core Functions and Application Scenarios

Tannic acid (also known as tannin) is a polyphenolic natural compound widely found in plants, possessing unique chemical and biological activities. With its various properties, including leather tanning, antioxidant, antibacterial, astringent, and metal-integrating effects, tannic acid has important and ever-expanding applications in numerous industrial and scientific research fields.

1. Major Traditional and Industrial Applications

Leather Industry (Tanning):

Core Application: Tannins can bind with collagen, transforming raw hides into durable, rot-resistant leather. It is the primary tanning agent in vegetable tanning.

Characteristics: Tannins impart a rich texture and specific color to leather (such as the light brown of vegetable-tanned leather). It is environmentally friendly and biodegradable, but the finished leather is relatively hard and prone to discoloration when exposed to water.

Ink and Dye Industry:

Traditional Ink: Tannins in tannins react with iron salts to form dark-colored iron tannate, a major component in the manufacture of blue-black ink and iron tannate ink.
Dye Mordants: High-quality tannins act as mordants, helping certain dyes (such as basic dyes) adhere to textiles (especially cotton and wool), improving colorfastness.
Water Treatment and Oil Extraction:

Scale Inhibitors and Dispersants: Industrial-grade high-quality tannins can inhibit the formation of scale such as calcium carbonate and calcium sulfate in water systems and disperse iron oxide and sludge.

Drilling fluid treatment agents: Industrial-grade tannic acid is used as a viscosity reducer and filtration reducer to improve drilling mud properties.

2. Pharmaceutical and Daily Chemical Applications

Food and Beverage Industry:

Clarifying and Stabilizing Agents: Food-grade tannins are used to clarify beer, wine, and fruit juices, removing protein and polyphenol polymer precipitates and improving product stability.

Flavor and Color: High-purity food-grade tannins are a significant source of astringency and color in beverages such as wine and tea. They also act as food antioxidants (e.g., preventing rancidity of oils).

Daily Chemicals and Personal Care:

Cosmetics:High-quality tannins are used as astringents to shrink pores, commonly found in toners and lotions. Their antioxidant properties are also used in anti-aging products.
Sunscreen Products:They absorb ultraviolet rays, acting as natural UV absorbers.
Deodorants:They bind to proteins, inhibiting odors produced by sweat decomposition.

3. Agricultural and Feed Applications

Animal Feed Additives: Appropriate addition can improve the protein utilization efficiency of ruminants, reduce methane emissions, and has certain antibacterial and antiparasitic effects.

Plant Protection: Can be used as a raw material or adjuvant for biological pesticides, utilizing its antibacterial and antiparasitic activities.

4. Emerging and High-Tech Applications

Functional Materials:

Adsorbent Materials:Industrial-grade tannic acid can be used to prepare adsorbents, efficiently removing heavy metal ions (such as lead, chromium, and mercury) and dyes from wastewater.

Coatings and Thin Films:High-quality tannic acid utilizes its coordination with metal ions to prepare anti-corrosion coatings, conductive thin films, or functional surfaces.

Chemistry and Energy:

Green Chemistry: Tannic acid, as a renewable raw material, is used in the synthesis of polymer materials, epoxy resin curing agents, etc.
Battery Materials: In lithium-sulfur batteries, tannic acid is used to immobilize polysulfides, improving battery performance.

Biomedical Engineering:

Tissue Engineering: High-quality, high-content tannic acid is combined with gelatin and other materials to prepare bioactive hydrogel scaffolds for wound dressings and bone repair.
Drug Delivery: High-quality, high-content tannic acid serves as a carrier material for encapsulating drugs to achieve controlled release.
