Frequently Asked Questions: Botanical Preservative Procurement

Direct answers for quality directors, formulators, and supply chain managers evaluating China's premier botanical manufacturing capabilities.

Which international quality certifications do UniCare's manufacturing facilities hold?
UniCare works in long-term manufacturing partnership with Chinese processing facilities operating under complete, verifiable quality management systems. These accreditations include GMP, EU-GMP, CEP (Certificate of Suitability to the European Pharmacopoeia), ISO 9001 (Quality Management), ISO 22000 (Food Safety Management), and HACCP. Certification scope aligns with specific product lines and market demands, and complete official audit copies are provided during vendor pre-qualification.
How does UniCare validate the antimicrobial potency and assay of each extract batch?
Each partner manufacturing plant features an autonomous analytical testing center. Routine release verification includes active marker quantification by validated HPLC or UV-Vis spectrophotometry, residual extraction solvent determination by gas chromatography (GC), organochlorine and multi-residue pesticide screening by GC-MS/MS, and toxic heavy metal screening (lead, arsenic, cadmium, mercury, copper) via ICP-MS. In addition, physical-chemical indicators (loss on drying, total ash, particle mesh size) and complete microbial limit panels are tested before any batch release.
What specific documentation accompanies enterprise commercial shipments?
Every shipment arrives with a complete, batch-specific Certificate of Analysis (COA) detailing tested values against contract specifications. On request, we provide comprehensive technical dossiers containing standard Operating Procedures (SOP), analytical test methods (MOA), material safety data sheets (MSDS), non-GMO statements, BSE/TSE-free attestations, allergen declarations, and origin certificates for customs clearance.
Can natural preservative specifications and particle sizes be customized for specific formulations?
Yes. UniCare delivers bespoke specification adjustments including targeted marker assay levels, specific solvent extraction ratios (e.g., 4:1, 10:1, 50:1), customized particle size distributions (from 80 mesh to ultrafine 200 mesh), and tailored bulk packaging options. All adjustments are executed following comprehensive technical feasibility and stability assessments.
How do plant polyphenols compare to synthetic preservatives like potassium sorbate or sodium benzoate?
While synthetic chemicals act solely as antimicrobial agents and frequently degrade under elevated temperatures or cause off-notes, high-purity botanical preservatives (such as oleuropein, punicalagins, and grape seed proanthocyanidins) provide a dual mechanism: cell-wall destabilization of pathogens coupled with potent antioxidant scavenging that halts lipid and color oxidation. Furthermore, they fulfill consumer clean-label expectations without compromising formulated shelf-life stability.
How do buyers request product catalogs, technical dossiers, or pilot testing samples?
Enterprise procurement teams and research formulators can submit sample requests through our Request a Catalog portal, by emailing [email protected] directly, or by calling our customer service desk at +86-028-85333989. Standard evaluation samples (50g to 500g) with matching lot COAs are dispatched via express air courier within 48 hours.
