Quercetin Anhydrous Powder 98% (Ultra-Low Moisture Grade)

What is Quercetin Anhydrous?t is Quercetin Anhydrous?

Green Spring Technology's premium Quercetin Anhydrous Powder is an ultra-low moisture, premium-grade flavonoid extracted from natural Sophora japonica L. Standardized to 98.0% purity by HPLC, this material undergoes a specialized thermal dehydration process to compress its residual water content strictly below 1.0%. It functions as a highly stable active raw material, specifically engineered to eliminate cross-reactive moisture transfer and prevent active ingredient degradation in complex, hygroscopic powder blends.

As a highly pure aglycone crystalline structure, it provides superior resistance to heat and chemical oxidation compared to standard dihydrate forms. Its refined physical matrix ensures enhanced bulk density and excellent powder flowability, making it the industry-standard choice for extending shelf-life stability in premium multi-ingredient hard capsules and solid dosage formulations.

Specification

Quality & Compliance  

• Elite Global Certifications: Our state-of-the-art manufacturing facility operates under strict cGMP conditions, holding active and fully verified BR

• CGS, IFS, ISO9001, ISO22000, Halal, Kosher, COSMOS, and dual USDA Organic & EU Organic certifications for seamless international customs clearance.

• Ultra-Pure Contaminant Control: Every production batch undergoes rigorous laboratory screening to ensure total compliance with strict FDA and European Commission limits. We guarantee heavy metals ≤10 ppm (Lead ≤1.0 ppm, Arsenic≤1.0 ppm, Mercury ≤0.1 ppm), negative pesticide residues, and full compliance with EU PAHs laws.

• Strict Organic Solvent Restriction: Processed exclusively utilizing pure water and food-grade ethanol, our validation protocols guarantee residual solvents strictly comply with USP <467> standards, ensuring a 100% methanol-free and acetone-free clean chemical matrix.

• Flawless Microbiological Profile: We enforce a zero-tolerance contamination policy on biological risks, ensuring Total Plate Count ≤1,000 cfu/g, Yeast & Mold ≤100 cfu/g, and a strict guaranteed absence of E. coli and Salmonella to accelerate internal QA/QC approval.

Key Advantages 

• Ultra-Low Moisture Stability: Engineered with a moisture content compressed strictly below 1.0% (vs. ~12% in standard dihydrate forms), this crystalline grade eliminates cross-reactive moisture transfer and actively prevents the degradation of adjacent active raw materials.

• Premium Formula Compatibility: This anhydrous chemical structure prevents color changes, spotting, or capsule shell softening when blended with highly hygroscopic or acidic ingredients, including Zinc compounds and Vitamin C (Ascorbic Acid).

• Enhanced Powder Density & Flowability: Featuring a high standardized bulk density (0.40 – 0.60 g/ml), the refined crystalline structure eliminates powder segregation and guarantees exceptional flowability on high-speed automatic encapsulation and tablet pressing lines.

• 100% Clean Label & Non-GMO: Processed under eco-friendly criteria with zero synthetic chemical additives, zero excipients, and no irradiation, this pure aglycone matrix fully aligns with modern clean-label demands and the COSMOS-approved standards for topical cosmetic applications.

Applications

• Advanced Dietary Supplements: Standardized as a premier active raw material for hard-shell capsules, compressed tablets, and solid dose matrices targeting multi-ingredient antioxidant complexes, lung health blends, and immune wellness formulations.

• Moisture-Sensitive Nutraceutical Complexes: Highly recommended for premium shelf-stable formulas combining highly hygroscopic raw materials, including Zinc, Vitamin C, and diverse amino acid powders, where water activity must be strictly restricted.

• Functional Foods & Solid Beverages: Perfectly suited for instant powder stick packs, dry-mix protein shakes, meal replacement bases, and wellness confectionery matrices that require dry-blending processing without chemical active degradation.

• Cosmetics & Personal Care (COSMOS-Compliant): Utilized in clean-beauty topical formulations, anti-aging serums, soothing facial creams, and protective skincare barrier lotions leveraging its pure, solvent-free aglycone structure for sensitive skin.
