Liposomal Quercetin 50% 70% 80%

Quercetin Dihydrate — Liposomal Bulk Raw Material for Anti-Aging & Beauty

Liposomal Quercetin delivers one of nature's most extensively researched flavonoid polyphenols, extracted from Sophora japonica and encapsulated at 50%, 70%, and 80% concentrations. Quercetin directly inhibits multiple matrix metalloproteinases (MMP-1, MMP-3, MMP-9) while simultaneously activating Nrf2-mediated antioxidant gene expression and suppressing NF-κB inflammatory signaling. Its dual anti-MMP and anti-inflammatory action makes it a cornerstone ingredient for matrix-shield formulations that defend collagen from both enzymatic and inflammation-driven degradation.

Available Purity Grades

• Quercetin Dihydrate 50% 70% 80% (HPLC) — Liposomal powder with phosphatidylcholine encapsulation for enhanced bioavailability.

Why Choose Our Liposomal Quercetin Dihydrate?

• Broad MMP Inhibition: Directly suppresses MMP-1 (collagenase), MMP-3 (stromelysin), and MMP-9 (gelatinase) through transcriptional downregulation, providing three-pathway collagen protection in a single ingredient.
• Nrf2 Antioxidant Activation: Triggers the Nrf2/ARE pathway to upregulate endogenous antioxidant enzymes including superoxide dismutase, catalase, and heme oxygenase-1, building the skin's own defense capacity.
• NF-κB Inflammatory Suppression: Blocks IκB kinase phosphorylation, preventing NF-κB nuclear translocation and halting the production of collagen-degrading inflammatory cytokines at the gene level.
• Anti-Glycation Properties: Reacts with carbonyl groups from reducing sugars, forming harmless adducts instead of advanced glycation end-products (AGEs) that cross-link and stiffen collagen fibers.
• Triple Concentration Range: Available at 50%, 70%, and 80% liposomal loading—the widest range in the portfolio—enabling formulators to fine-tune potency for light gels, rich creams, or concentrated oral doses.
• Flavonoid Bioavailability: Liposomal encapsulation overcomes quercetin's notoriously poor oral bioavailability (2-5%) by protecting it from first-pass metabolism and enhancing lymphatic uptake for systemic delivery.

Target Applications

• Comprehensive Anti-Aging Brands: Companies developing multi-action serums that combine MMP inhibition, antioxidant gene activation, and anti-inflammatory suppression in a single elegant formulation.
• Oral Beauty Supplement Manufacturers: Nutricosmetic brands leveraging liposomal quercetin's enhanced bioavailability for ingestible beauty products that protect skin collagen systemically.
