Tannic Acid
SINOBIO
2916399090
Name: Tannic Acid
CAS: 1401-55-4
Chemical formula: C76H52O46
Appearance: Amorphous Light brown powder
Tannic acid is a naturally occurring plant polyphenol belonging to the hydrolyzable tannin class, characterized by its unique chemical structure and broad biological activity. The following provides a detailed overview from the perspectives of chemical properties, sources, applications, and health effects:
The chemical formula for tannic acid is typically represented as C₇₆H₅₂O₄₆, corresponding to decagalloyl glucose; however, it is actually a mixture formed by the esterification of 2–12 galloyl groups with glucose or quinic acid. Its molecular weight is approximately 1701.2 g/mol, containing multiple phenolic hydroxyl groups (-OH), which confer weak acidity (pKa ≈ 6) and strong reducing properties.
-Appearance: Light yellow to brownish-yellow amorphous powder that gradually darkens when exposed to air and light.
-Solubility: Soluble in hot water, ethanol, and acetone; insoluble in ether.
-Odor and taste: Odorless or with a slight characteristic odor; extremely bitter taste (due to its ability to precipitate when combined with proteins).
Tannic Acid is widely found in plants, especially:
- Trees: such as the bark and fruit (acorns) of oak trees (Quercus spp.) and the galls of sumac (Rhus semialata).
- Fruits and nuts: unripe persimmons, pomegranates, grape seeds, tea leaves (especially black tea), and coffee beans.
- Other plants: Tara pods, and the sap of the lacquer tree (Toxicodendron vernicifluum).
| Items | Standards |
| The Amount Of Tannic Acid Content (Dry Basis)/(%) | 90.0% min |
| Appearance | Amorphous Light brown powder |
| Odor | Practically odourless |
| Taste | Neutral/slight astringent taste |
| Solubility | Very soluble in water,freely soluble in aceton,in alcohol |
| Loss On Drying /(%) | 9.0 max |
| Residue On Ignition /(%) | 1.0 max |
| Arseni | 3ppm max |
| Lead | 2ppm max |
| Heavy Metal/(Ug/g) | 20 ppm max |
| Gums, Dextrin Test | No turbidity |
| Resins Test | No turbidity |
| Gallic Acid /(%) | 4.0max |
*Traditional Uses:
-Hemostasis (by constricting blood vessels and precipitating proteins).
-Treatment of diarrhea, skin burns, throat infections, and mild inflammation.
-As an antidote (adsorbing heavy metals and toxins).
*Modern Research:
-Antioxidant: Clears free radicals, slows aging, and prevents cancer and cardiovascular disease.
-Anti-inflammatory: Inhibiting inflammatory factors (such as TNF-α, IL-6), alleviating skin redness and swelling, and reducing allergies.
-Antimicrobial/antiviral: Effective against Staphylococcus aureus, Escherichia coli, and certain viruses.
-Diabetes management: May function by regulating blood sugar levels and improving insulin sensitivity.
-Leather industry: Combines with collagen to make leather soft and corrosion-resistant.
-Textiles and dyes: Used as a mordant (combines with metal salts to fix dyes to cellulose fibers, such as cotton).
-Wood treatment: Used for “ebonizing” wood or converting rust (forming a black protective layer).
-Alcohol denaturant: Added to industrial alcohol to prevent accidental ingestion.
*Food additives: Used as an acidulant or antioxidant (must comply with safety dosage standards).
*Skincare products:
-Tightens pores and reduces oil secretion (used in toners and masks).
-Anti-aging (promotes collagen synthesis and reduces wrinkles).
-Treats acne and minor wounds (antibacterial and anti-inflammatory).
Tannic acid is a naturally occurring compound with a complex structure and diverse functions, finding significant applications in medicine, industry, and daily life. Its antioxidant, anti-inflammatory, and antibacterial properties have made it a hot topic in modern research, though careful dose control is necessary to avoid potential risks. In the future, as mechanisms in areas such as diabetes management and skin health are further explored, the application prospects for tannic acid may be further expanded.
