Kaempferol High-purity Antioxidant Brightening Raw Material (CAS 520-18-3)
Kaempferol is a high-purity flavonoid active monomer refined from high-quality natural pagodatree flower and plant raw materials via low-temperature enzymatic hydrolysis, high-precision membrane purification and freeze-drying technology.
As a classic brightening and anti-photoaging flavonoid ingredient in cosmetics, it integrates three core efficacies of brightening whitening, anti-oxidation and mild anti-inflammation, with outstanding tyrosinase inhibitory activity and strong free radical scavenging ability.
Different from traditional whitening ingredients that are irritating and single-functional, and ordinary antioxidant raw materials with weak brightening effect, our cosmetic-grade 98% high-purity kaempferol features pure natural source, ultra-mild and non-irritating, high activity and stable formula performance.
Key Benefits
• High-purity Flavonoid Monomer, Mild Whitening & Zero Irritation: 98% high-purity kaempferol single flavonoid monomer, refined and purified to remove plant impurities. Pure natural plant source, no chemical whitening agent addition, mild and non-sensitizing, realizing safe and gentle brightening for full skin types.
• Strong Tyrosinase Inhibition, Source Block Melanin: Possesses excellent tyrosinase inhibitory activity, effectively blocks melanin synthesis and deposition, fades existing pigmentation, improves dull and yellow skin tone, and achieves uniform and bright skin complexion.
• Exclusive Anti-photoaging, Repair Sun Damage: Targets UV-induced photoaging damage, scavenges light-induced free radicals, improves sunburn dullness, rough texture and light wrinkles, and repairs sun-damaged skin barrier.
• Efficient Antioxidant, Delay Skin Aging: Deeply scavenges various harmful free radicals in the skin, blocks lipid peroxidation damage, inhibits collagen oxidation loss, improves fine lines and sagging, and delays skin chronological aging.
• Mild Anti-inflammatory & Anti-pigmentation, Stabilize Skin: Mildly relieves skin inflammatory irritation, reduces immune sensitivity, inhibits inflammatory pigment deposition, prevents post-inflammation darkening, and balances skin healthy state.
• Excellent Compatibility & Industrial Stability: Good solubility and wide formula adaptability, can be freely compounded with various flavonoids and brightening 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 is the core advantage of kaempferol compared with quercetin and luteolin?
A1: Kaempferol is a rare flavonoid monomer with dominant brightening and anti-photoaging efficacy. While retaining excellent anti-oxidation and mild anti-inflammation effects, it has stronger tyrosinase inhibitory activity and melanin fading ability than other flavonoids. It is specially targeted at sun dullness and photoaging problems, making up for the weak brightening defect of conventional flavonoid raw materials.
• Q2: What is the recommended addition ratio of kaempferol in skincare formulas?
A2: Conventional antioxidant maintenance products: 0.02%-0.1%; Mild brightening whitening formulas: 0.1%-0.3%; Anti-photoaging & post-sun repair products: 0.05%-0.2%; Multi-effect anti-aging 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 kaempferol cause formula yellowing or precipitation?
A3: High-purity kaempferol is fine yellow crystal powder with faint natural color. After standardized ethanol-assisted dissolution and low-temperature feeding process, the formula is clear and stable. Strictly controlling the addition amount and avoiding long-term high-temperature and strong light environment will not cause obvious yellowing, browning or precipitation delamination, which does not affect product appearance and quality.
• Q4: What ingredients is kaempferol suitable for compounding with?
A4: Kaempferol has excellent formula compatibility. It can be perfectly compounded with quercetin, luteolin, arbutin, panthenol, centella asiatica extract and other brightening and soothing ingredients to form a flavonoid synergistic brightening system, which significantly improves the formula's whitening, anti-photoaging and repair efficacy.
• Q5: How to store kaempferol 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 brightening and antioxidant 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.
