Which certifications do UniCare's manufacturing partners hold?

UniCare works with Chinese manufacturers whose quality systems are certified to standards including GMP, EU-GMP, CEP, ISO 9001, ISO 22000 and HACCP. Certification scope varies by product line, and the relevant certificates are shared for each ingredient during supplier qualification.

How are UniCare botanical extracts tested before release?

Each partner factory has independent testing capability. Typical release testing covers marker compound assay by HPLC or UV, residual solvents by GC, pesticide residues by GC-MS/MS, heavy metals (lead, arsenic, mercury, cadmium, copper) by ICP-MS, microscopic and TLC identification, moisture or loss on drying, ash, microbial limits, pH, conductivity and sulfur dioxide residue.

What documents are supplied with each batch?

Each lot is supplied with a batch-specific Certificate of Analysis. Specification sheets, MSDS, methods of analysis and regulatory statements can be provided on request during qualification.

Can UniCare customize ingredient specifications?

Yes. The customized service covers adjustments such as assay level or extract ratio, particle size and packaging format, subject to technical feasibility and regulatory requirements in the destination market.

How can buyers request a catalog or samples?

Buyers can request the product catalog and samples through the Request a Catalog page, by email at info@unicare-bio.com, or by phone at +86-028-85333989.

Assay Range: 10% - 98% HPLC

Global Compliance Validation

Manufacturing facilities are audit-ready for cGMP, EU-GMP, ISO 22000, and HACCP compliance. Finished powders undergo exhaustive screening for polycyclic aromatic hydrocarbons (PAHs), ethylene oxide (EtO), elemental impurities (ICP-MS), and multi-residue pesticide screens.

Zero-EtO / Strict EU 2023/915 Limits

Sector Applications

Macro Industry Solutions & Cross-Market Application

Meeting differentiated technical specifications across dietary longevity, neuroceuticals, functional cosmetics, and veterinary medicine.

Cellular Senolytics & Longevity

Fisetin from Cotinus coggygria is recognized globally as one of the most potent natural senolytic agents, inducing apoptosis in senescent cells. Formulators specify our 98% pure crystal powders for clinical longevity stacks alongside Quercetin and Resveratrol.

Target Market: North America & EU Dietary Brands

Neuroprotective & Nootropic Stacks

Preclinical data demonstrates Cotinus flavonoids cross the blood-brain barrier, stimulating signaling cascades (such as ERK/CREB) that support memory consolidation and neuronal survival. We supply micronized grades tailored for rapid capsule bioavailability.

Target Mesh: 80-120 Mesh Homogeneity

Dermatological Cosmetics & Topical Anti-Aging

Crude Cotinus coggygria extract contains high ratios of sulfuretin, gallic acid, and myricetin with exceptional tyrosinase inhibition and anti-erythema activity. Our water/butylene-glycol dispersible grades integrate seamlessly into clinical serums.

Procurement FAQ

Frequently Asked Questions · Technical Procurement

Essential guidance for purchasing agents, formulators, and compliance managers qualifying China Cotinus Coggygria PE manufacturing partners.

What is the botanical relationship between Cotinus coggygria PE and commercial Fisetin?

Cotinus coggygria (commonly known as Smoke Tree or Smokebush) is the world's primary natural botanical source of the flavone Fisetin. While Fisetin can be chemically synthesized or isolated from Rhus succedanea, high-potency Cotinus coggygria extraction provides clean, natural-origin material certified non-synthetic, supporting clean-label positioning for global premium supplement brands.

Which primary specifications and assay levels are available from your factories?

We provide a standardized spectrum including Cotinus Coggygria P.E. 10%, 50%, and 98% Fisetin (HPLC), as well as custom ratio extractions (10:1, 20:1, 50:1) maintaining the natural flavonoid and tannin matrix. Specialty water-dispersible and ultra-micronized formats are available on request.

How do partner facilities guarantee batch-to-batch chemical stability?

Batch stability is achieved via closed continuous countercurrent extraction where solvent flow rates, temperature profiles, and raw material moisture contents are monitored automatically. Post-extraction, state-of-the-art analytical equipment (Agilent 1290 UHPLC and Shimadzu LC-20AT systems) validates active retention across every drum released.

What quality management and international manufacturing certifications are maintained?

Our cooperative production plants are audited and operate under GMP, EU-GMP, ISO 9001, ISO 22000, and HACCP certifications. Regulatory packages (HALAL, KOSHER, non-GMO statements, BSE/TSE statements, and Allergen declarations) are provided directly to qualify your supplier master file.

How does your facility address residual solvents and heavy metal limits?

We operate strict USP <467> and EP 5.4 Class 2 & Class 3 residual solvent testing via Shimadzu GC2010 head-space gas chromatography. Ethanol recovery is tightly vacuum-distilled to ensure residual solvent contents stay well below 5000 ppm (typically below 500 ppm). Heavy metals are controlled strictly below 10 ppm total via atomic absorption and ICP-MS.
