Description

Tannic Acid USP

Tannic Acid USP is a high-purity, naturally derived polyphenolic compound used in pharmaceutical, nutraceutical, and industrial applications for its astringent, antioxidant, and stabilizing properties. Compliant with United States Pharmacopeia (USP) standards, it provides consistent performance in topical, oral, and formulation systems requiring protein precipitation or oxidative stability. Tannic Acid
• Is a USP-compliant polyphenolic compound for pharmaceutical and industrial applications
• Is used as an astringent, antioxidant, and stabilizer
• Is suitable for topical, oral, and compounded dosage forms
• Provides antioxidant protection and formulation stability
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data
Tannic Acid USP is chemically described as a mixture of Polygalloyl esters of Glucose. It appears as a light yellow to brown amorphous powder, soluble in water and alcohol, producing acidic solutions with strong protein-precipitating properties.
In pharmaceutical and nutraceutical applications, Tannic Acid USP is used in:
• Topical formulations as an astringent and wound protectant
• Oral products for treatment of sore throat, diarrhea, and mucosal irritation
• Antioxidant systems to prevent degradation of sensitive actives
• Tanning, dyeing, and industrial formulations as a chelating and stabilizing agent
• Research applications in protein interaction and polymer cross-linking studies
Tannic Acid USP functions as both an antioxidant and astringent agent, stabilizing formulations while providing therapeutic effects in topical and oral applications. Its broad compatibility with excipients and bioactive compounds makes it highly versatile in formulation development.
CarboMer supplies Tannic Acid USP with control over assay, purity, moisture content, and microbial limits. Material meets USP monograph specifications and is suitable for regulated pharmaceutical, nutraceutical, and industrial applications.
