Standardized Quercetin Dihydrate Powder (95% - 98% HPLC)

What is Standardized Quercetin Dihydrate Powder?

Quercetin Dihydrate Powder is a botanical bioflavonoid crystalline compound derived from the dried flower buds of Софора джапоника л. Chemically identified as a pentahydroxyflavone bound with two water molecules, this bulk ingredient is standardized via КЖПХ (HPLC) to a purity profile of 95% to 98%. Manufactured by Технология "зеленый источник", the material maintains a verified crystalline structure and documented batch-to-batch chemical uniformity required for regulated nutritional formulations.

This compendial-grade, clean-label powder functions as a cellular antioxidant and an anti-inflammatory metabolic pathway agent. The standardized ingredient is molecularly stable for incorporation into advanced oral solid dosages, including dietary supplements, hard capsules, and tablets, supporting cardiovascular health and immune system formulations without structural degradation during commercial processing.

Quality & Compliance  

• Global System Certifications: Manufacturing infrastructure and operations are audited and certified under BRCGS, IFS, ISO 9001, and ISO 22000 quality management standards to verify trace-level international supply chain compliance.

• Dietary & Organic Status: Materials maintain documented Halal, Kosher, EU Organic, and USDA Organic status, qualifying the ingredient for cross-border customs clearance and global market accessibility.

• Cosmetic & Personal Care Grade: Approved under COSMOS Natural standards, establishing formulation safety and regulatory verification for natural cosmetics and topical personal care products.

• Impurity & Residue Controls: Batch testing via ICP-MS and Chromatography confirms individual heavy metals remain within pharmacopeial limits (Pb ≤1.0 ppm, As ≤1.0 ppm, Cd ≤0.1 ppm, Hg ≤0.1 ppm), with pesticide and solvent residues compliant with USP and EP monographs.

• Microbiological Security: Microbe specifications enforce negative parameters for standard pathogens, with documentation verifying each batch tests negative for E. coli, Salmonella, and Staphylococcus aureus adhering to pharmacopeial testing frequencies.

• Document Traceability: Every commercial shipment is dispatched with a batch-specific Certificate of Analysis (CoA) and regulatory data sheets to accelerate industrial vendor qualification and QA approval processes.

Key Advantages

• Dihydrate Crystalline Stability: Industrial manufacturing protocols preserve the native dihydrate crystalline structure of the molecule. This crystalline integrity prevents chemical degradation, thermal discoloration, or active ingredient loss during automated high-speed capsule filling and tableting processes.

• Standardized Particle Distribution: Standardized to a uniform granulometry of 100% through 80 mesh, the bulk powder ensures consistent matrix dispersion in solid dosage blending. This predictable particle distribution eliminates processing stratification and supports uniform homogeneity across large-scale industrial batches.

• 100% Botanical Clean Label: Derived exclusively from the dried flowers and buds of Sophora japonica L., this pure botanical ingredient contains zero synthetic carriers, chemical anti-caking agents, or common allergens, aligning with international regulatory clean-label and non-GMO requirements.

• Documented Physical Flowability: Engineered with a controlled bulk density and a tapped density range of 0.25–0.45 g/mL, the crystalline powder features predictable mechanical behavior in automated manufacturing hoppers. The documented physical profile minimizes material caking, optimizing equipment processability and maintaining mechanical yield efficiency.

Applications

• Dietary Supplements: Standardized for integration into solid oral dosage delivery systems, including hard gelatin capsules, vegetable capsules, and compressed tablets. The compendial-grade crystalline powder provides verified bulk stability and uniform matrix mixing for multi-ingredient metabolic and health formulation profiles.

• Cosmetics & Personal Care: Compliant with COSMOS Natural verification standards, the bioflavonoid functions as a natural topical antioxidant. Technical compatibility extends to anhydrous formulations, solid pressed balms, and stabilized suspensions, or incorporates into localized skincare creams and protective emulsions that chemically accommodate solid dispersed micro-particles.

• Functional Food & Beverages: Tailored for clean-label markets, the botanical ingredient is applicable for dry-mix wellness formulations, nutritional powder mixes, and meal replacement shakes. The standardized 100% through 80 mesh granulometry enables consistent dry blending into food matrices without altering the physical structural integrity of the final product.

• Nutraceutical Confectionery: The controlled particle distribution ensures homogeneous material dispersion in active matrix delivery systems, including chewable tablets and compressed fortified lozenges. The crystalline structure prevents premature ingredient interaction, maintaining active stability through industrial baking and cold-compression confectionery processing lines.

Technical FAQ

Q1: What methodologies and compliance standards control the loss on drying (LOD) for Quercetin Dihydrate Powder?

A: Industrial vacuum-drying protocols control the Loss on Drying (LOD) within 9.0%–12.0%, adhering to both USP and EP monographs for the dihydrate form. This documented hydration profile maintains crystalline lattice stability and prevents active degradation, supporting regulatory compliance audits for global nutraceutical brands.

Q2: Quercetin Dihydrate exhibits hydrophobic properties. What formulation pathways improve dissolution profiles without altering the native 80-mesh structure?

A: Standard Quercetin Dihydrate Powder is practically insoluble in water (approximately 0.125 g/L), limiting liquid oral dosages. To enhance dissolution rates in advanced solid oral formulations, options include compounding via alkaline solubilization, co-solvent systems, or transitioning to a cyclodextrin-encapsulated complex to modify material behavior.

Q3: What are the physical flowability metrics of quercetin powder during automated manufacturing?

A: The bulk material features a particle size of 100% through 80 mesh and a tapped density range of 0.25–0.45 g/mL. Due to inherent electrostatic cohesion, incorporating glidants such as 0.5% Silicon Dioxide prevents hopper bridging during processing. Alternatively, a customized free-flowing granular grade is available for high-speed tablet compression lines.
