tannic acid Relevant regulations
- FDA:Tannic acid is recognized by the FDA as a Generally Recognized as Safe (GRAS) food additive (with limitations) used as a flavoring agent and antimicrobial.
- EFSA:The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that tannic acid is safe as a feed additive for all animal species, consumers, and the environment.
difference between tannin and tannic acid
Tannins and tannic acid are related by category. Tannins are a general term referring to a class of polyphenolic compounds in plants that can bind to proteins. Based on their chemical structure, they can be divided into two main categories: hydrolyzable tannins and condensed tannins, which are widely found in plant tissues such as bark, fruits, and tea leaves.
Tannic acid, on the other hand, is a specific member of the hydrolyzable tannin family, with a defined chemical structure and molecular formula, and is mainly derived from specific plants such as gallnut and talacornu.
tannic acid benefits
tannic acid for bleeding
Tannic acid is a natural hemostatic agent. Its hemostatic effect primarily stems from its ability to interact with proteins in the blood, thereby influencing the coagulation process.
It can act as a plasma protein precipitant, binding to plasma proteins through hydrogen bonding and hydrophobic interactions. In hemostatic applications, tannic acid inhibits platelet activation and thrombus formation. This mechanism involves binding to and inhibiting the activity of protein disulfide isomerases, thereby reducing platelet aggregation and integrin activation.
tannic acid tanning leather
Tannins play a central role in leather tanning, transforming perishable animal hides into chemically stable, water- and heat-resistant leather. During tanning, tannin molecules penetrate the interfiber spaces and cross-link with collagen chains, fixing the leather fiber structure and preventing them from sticking together.
This gives the leather its softness, fullness, and mechanical strength. Leather tanned with hydrolyzable tannins (such as tannic acid) has a light color and uniform texture, suitable for making high-grade vegetable-tanned leather, often used for products requiring high durability, such as shoe soles, belts, bags, and equestrian equipment.
tannic acid for skin
Tannic acid offers multiple benefits to the skin. First, it forms a physical barrier, protecting the skin from external irritants and artificial sweat, effectively inhibiting skin inflammation. Second, tannic acid is a powerful antioxidant, maintaining skin elasticity. Its anti-inflammatory, antibacterial, and astringent properties also make it an effective ingredient for treating acne and relieving skin redness and swelling.
tannic acid for hair
Tannic acid offers multiple benefits for hair, showing particular potential in hair loss prevention and care. Tannic acid can firmly bind to keratin on the hair surface through hydrogen bonding, forming a stable coating.
More importantly, tannic acid acts as an "adhesion mediator," its unbound phenolic hydroxyl sites effectively adsorbing and storing functional hair care ingredients such as salicylic acid, niacinamide, and dextropanol, forming complexes. When hair comes into contact with moisture, these active ingredients are slowly released and transported along the hair strand to the hair follicle, achieving controlled-release drug delivery.
tannic acid uses
Tannic acid in manufacturing
Tannic acid is a multifunctional natural polyphenol compound with a wide range of applications across various manufacturing sectors. Its most common industrial uses include leather tanning, blue ink production, leveraging its ability to form stable complexes with iron salts; stain removal, utilizing its strong protein-binding properties to treat organic stains; and paper sizing, where it enhances the surface strength and printability of paper products. Beyond these traditional applications, tannic acid also serves in metal corrosion inhibition, textile dyeing as a mordant, wine and juice clarification.
Tannic acid in the pharmaceutical field
It possesses a variety of pharmacological activities. In topical preparations, tannic acid is commonly used to treat mild burns, bedsores, diaper rash, and oral mucosal inflammation. It forms a protective film by precipitating proteins, reducing tissue exudation and promoting wound healing. Its hemostatic properties have been used to prepare hemostatic gauze, sponges, and other materials, regulating the coagulation process by enriching calcium ions and inhibiting protein disulfide isomerase activity. In oral preparations, tannic acid can be used to treat diarrhea, utilizing its astringent properties to reduce intestinal mucosal secretion.
Tannic acid in Skincare
Tannic acid is used in a variety of skincare products due to its multiple benefits, including astringency, antioxidant properties, anti-inflammation, and antibacterial effects. In cleansers, tannic acid helps control oil secretion and shrink pores, making it suitable for oily and acne-prone skin. In serums and creams, its antioxidant properties can eliminate free radicals, delay photoaging, and reduce wrinkles, and it is often added to anti-aging products. In face masks, tannic acid can soothe inflammation and calm the skin, making it suitable for sensitive and acne-prone skin. In addition, it is commonly found in acne treatment products, utilizing its antibacterial and astringent properties to reduce acne breakouts.
Tannic acid feed additive
Tannic acid, as a feed additive, is now widely used in poultry, ruminant, pig, and aquaculture, primarily for its multiple benefits. In terms of growth performance, adding tannic acid can significantly improve the average daily weight gain and feed conversion ratio of broilers, piglets, and sheep. Regarding gut health, it can effectively reduce the incidence of diarrhea. In terms of antioxidant and anti-inflammatory properties, tannic acid can alleviate oxidative stress. As a safe, green, and residue-free plant-based additive, tannic acid has become an important choice for replacing antibiotics and improving animal health and production efficiency.

FAQ
Q: Does coffee have tannic acid?
A: Coffee does contain tannins, but in very low amounts. The astringency of coffee primarily comes from other polyphenols, such as chlorogenic acid. Although the term "tannins" is often used to refer to tannins in general, pure tannins are more commonly found in tea than in coffee.
Q: Do tannins cause itchy skin?
A: Tannins have astringent properties and may cause dryness and irritation when applied topically. For some, this can trigger contact dermatitis or worsen eczema. However, individual reactions vary-while pure tannins may cause irritation, tannins in food or skincare products are generally well-tolerated unless an allergic reaction occurs.
