Quercetin High-purity Antioxidant Anti-inflammatory Raw Material(CAS 117-39-5)
Quercetin is a high-purity flavonoid active monomer refined from high-quality natural pagodatree flower raw materials via low-temperature wall breaking, enzymatic hydrolysis and high-precision membrane purification technology.
As one of the most active and comprehensive natural flavonoids, it integrates three core efficacies of anti-oxidation, anti-inflammation and anti-glycation, with stronger and more durable comprehensive activity than ordinary plant antioxidants.
Different from single-effect antioxidant raw materials and mild soothing ingredients with slow effect, our cosmetic-grade 98% high-purity quercetin features pure natural source, ultra-mild and non-irritating, high activity and stable formula performance.
Key Benefits
• Triple Efficacy Integration, Multi-dimensional Anti-aging: Integrates anti-oxidation, anti-inflammation and anti-glycation triple core efficacy, covering oxidative aging, light aging and glycosylation aging. It solves various skin aging problems in all directions, with more comprehensive efficacy than single-function antioxidant raw materials.
• Ultra-high Antioxidant Activity, Deep Free Radical Scavenging: 98% high-purity flavonoid monomer, with strong free radical scavenging capacity. It deeply removes harmful free radicals in the skin, blocks oxidative damage from the source, delays skin aging, and improves dull and yellow skin tone.
• Efficient Anti-inflammatory & Soothing, Rapid Stability: Precisely inhibits inflammatory factor expression, quickly relieves sensitive redness, dry swelling and itching discomfort caused by season changes, external stimulation and sun exposure, calms fragile skin, and realizes rapid soothing repair.
• Exclusive Anti-glycation & De-yellowing, Brighten Turbid Skin: Inhibits collagen glycosylation and cross-linking reaction, improves skin yellowing, turbidity and tired complexion caused by glycation, effectively removes skin yellowness, and restores translucent and bright skin tone.
• Barrier Repair & Anti-pigmentation, Stable Skin State: Repairs damaged skin barrier, enhances skin self-resistance, reduces skin sensitivity, inhibits inflammatory pigment precipitation, improves uneven skin tone, and maintains long-term healthy skin state.
• Excellent Compatibility & Industrial Stability: Good solubility and wide formula adaptability, can be freely compounded with various plant flavonoids and skincare active ingredients to achieve synergistic efficacy amplification. Stable formula performance, no discoloration or precipitation during production and storage, suitable for industrial mass production.

Frequently Asked Questions (FAQ)
• Q1: What are the unique advantages of quercetin compared with luteolin and ordinary antioxidants?
A1: Quercetin is a rare triple-effect flavonoid monomer with anti-oxidation, anti-inflammation and anti-glycation functions. It makes up for the single efficacy of ordinary antioxidant ingredients, has stronger free radical scavenging ability than conventional plant raw materials, and adds exclusive anti-glycation and de-yellowing efficacy. It can comprehensively improve aging problems with more comprehensive and practical efficacy.
• Q2: What is the recommended addition ratio of quercetin in skincare formulas?
A2: Conventional antioxidant maintenance products: 0.02%-0.1%; Anti-glycation brightening formulas: 0.1%-0.3%; Sensitive skin soothing repair products: 0.05%-0.2%; Anti-aging high-efficiency formulas: 0.1%-0.4%; Mask essence formulas: 0.05%-0.2%. It is recommended to dissolve with ethanol first and add at low temperature (below 40℃) to ensure uniform dispersion and maximum activity retention.
• Q3: Will quercetin cause formula discoloration or precipitation?
A3: High-purity quercetin is light yellow crystal powder with faint natural color. After standardized dissolution and low-temperature feeding, the formula is stable and transparent. Strictly controlling the addition amount, avoiding high temperature and long-term strong light exposure will not cause yellowing, browning or precipitation delamination, which does not affect product appearance and quality.
• Q4: What ingredients is quercetin suitable for compounding with?
A4: Quercetin has excellent formula compatibility. It can be perfectly compounded with luteolin, centella asiatica extract, panthenol, beta-glucan, hyaluronic acid and other soothing and moisturizing ingredients to form a flavonoid synergistic system. It can also be compounded with antioxidant and anti-aging ingredients to comprehensively upgrade the formula's multi-effect skincare performance.
• Q5: How to store quercetin to maintain high activity?
A5: Sealed, light-proof and low-temperature storage (2-8℃) is required. Avoid high temperature, strong light, humid environment and contact with strong oxidants to prevent activity attenuation and oxidation discoloration. Seal immediately after opening and use up within the validity period to ensure stable efficacy.
• Q6: Support trial order and professional technical guidance?
A6: Yes, we support 100G small batch trial order to meet customer formula debugging and sample production needs. All batches have stable indicators and sufficient inventory. We provide professional pre-dissolution guidance, low-temperature feeding process suggestions and formula optimization technical support, supporting long-term bulk supply and global delivery.
