Kaempferol Powder

High-Purity Kaempferol Powder Extract - 98% Standardized Flavonol for Advanced Nutraceutical & Cosmetic Applications

Yanxi Biotech supplies premium-grade Kaempferol Powder at ≥98% purity, extracted from Sophora japonica using advanced isolation technology. This yellow fine powder delivers standardized 3,5,7,4'-tetrahydroxyflavone (C15H10O6), a potent flavonol antioxidant that modulates cellular pathways linked to oxidative stress, inflammation, and premature aging. With strict quality control under ISO 22000, HACCP, and Halal certifications, our product ensures stable supply for manufacturers developing high-performance dietary supplements, anti-aging skincare formulations, and functional food ingredients. All batches pass 80-mesh particle size analysis with <5% moisture content, guaranteeing uniform dispersion in complex formulations.

​​​​​​​ Key Advantages for Your Formulations

Our product addresses significant industry challenges. Many manufacturers have issues with unstable flavonoid extracts which break down during processing or do not provide consistent bioactivity. Yanxi Biotech's state-of-the-art extraction technique strips off interfering waxes and tannins to isolate pure kaempferol.

With a high purity specification of 98%, this provides predictable dosing to supplement formulators looking to support cardiovascular health and immune modulation. This condensed form of , reduces the requirement for large serving quantities usual with crude plant extracts.

Thermal stability testing proved that our powder keeps its antioxidant potency for 60 minutes at 90℃. The heat resilience makes it suitable for encapsulation, tablet compression and beverage pasteurisation processes where less stable botanicals are destroyed.

The 80-mesh particle size blends smoothly with powdered supplements, beverage mixes and cosmetic emulsions without clumping. Your production team benefits from the consistent flowability which lowers batch-to-batch variability.

Applications Across Multiple Industries

Development of Dietary Supplements

Formulators include this flavonol to antioxidant complexes, bone health products and metabolic support blends. Its capacity to block NF-κB inflammatory pathways is proven, making it an ingredient to consider for joint health and immunological balance formulas.

Anti-Ageing Skin Care Products

Cosmetic chemists use kaempferol's free radical scavenging ability to combat photoaging in serums and creams. Its involvement in shielding fibroblasts from oxidative damage is consistent with claims of collagen retention.

Functional Foods Ingredients

Our powder is used by beverage and nutrition bar companies in items sold as cellular health products. The natural yellow colourant offers visual appeal and functional benefits.

Scientific Foundation & Bioactivity

Kaempferol is a flavonoid, belonging to the flavonol subclass, with hydroxyl groups at positions 3, 5, 7 and 4'. This chemical framework allows it to donate electrons to neutralise reactive oxygen species.

Research has demonstrated its ability to modulate cell signalling cascades such as MAPK and AKT pathways. These processes are responsible for the reported effects on osteoblast differentiation, reduction of adipocyte production and suppression of inflammatory mediators.

Clinical studies on flavonoid intake reveal possible benefits for vascular function and maintenance of bone density. Individual outcomes may differ, but standardised potency of pure Kaempferol Powder provides a framework for evidence-based product positioning.

The problem of bioavailability still persists as kaempferol is a hydrophobic compound. It is usually used in combination with absorption enhancers or liposomal delivery systems to improve intestinal uptake.

Quality Assurance & Certifications

Each production batch is subjected to strict HPLC examination to confirm purity criteria. Heavy metal screening is done to conform to international requirements of safety for food and cosmetic substances.

Our plant is certified to ISO 22000 food safety standards and is HACCP validated. Kosher and Halal certifications provide market access for products that have a wide set of consumer preferences.

SGS third party test verifies no pesticide residues and microbiological infestation. Our Botanical Sourcing to Final Packaging offerings give you complete traceability for your regulatory paperwork needs.

Stability studies show 24 month shelf life when stored in a sealed container, away from moisture and direct light. The added stability helps ease inventory turnover demands for overseas customers.

Packaging & Shipping

We provide flexible packing options tailored to your order volume. Small scale formulators are able to order 1kg foil packs for R&D experiments. Most mid-sized manufactures prefer 5kg boxes for early manufacturing runs. Fibre barrels are 25kg which optimises freight costs for high volume customers.

All shipments are placed in sealed inner bags and nitrogen flushed to prevent oxidation in transit. Export documentation meets customs regulations in more than 100 destination countries. Sensitive items are shipped door-to-door with temperature monitoring by our logistical partners.

Standard lead time is 1-3 working days upon payment confirmation for in-stock goods. We are strategically warehousing across Europe and North America to assist with speedy replenishment for existing customers.
