Silymarin High-purity Oil-control Antioxidant Anti-inflammatory Raw Material(CAS 22888-70-0)
Silymarin is a high-purity flavonolignan complex active substance refined from high-quality natural milk thistle fruit raw materials via low-temperature crushing, enzymatic hydrolysis and high-precision membrane purification technology.
It is a rare oil-soluble and water-soluble dual-effect antioxidant ingredient in the cosmetic industry, compounded by silybin, isosilybin, silydianin and silychristin, with outstanding oil oxidation resistance and UV repair capabilities.
Different from ordinary single-function antioxidants and common plant soothing ingredients, our cosmetic-grade 98% high-purity silymarin features pure natural plant source, ultra-mild and non-irritating, high activity and stable formula performance.
It has multi-dimensional skincare advantages: firstly, it targets oily skin lipid oxidation, inhibits sebum peroxidation, improves oily dullness and greasy skin texture, and achieves long-term oil-control and purifying effects; secondly, it deeply scavenges skin free radicals, resists oxidative aging and ultraviolet photoaging damage, significantly improves sun-induced erythema, peeling and pigmentation, and repairs light-aged damaged skin; thirdly, it mildly inhibits inflammatory factor release, relieves skin redness and sensitivity caused by UV stimulation and oily inflammation, and stabilizes fragile oily skin; fourthly, it protects skin cell DNA, enhances skin self-repair ability, inhibits abnormal proliferation of fibroblasts, and prevents rough texture and dull aging caused by external damage. In addition, silymarin has excellent formula compatibility, can be perfectly compounded with quercetin, luteolin, kaempferol, vitamin C and ferulic acid to form a water-oil dual anti-oxidation system, which greatly improves the formula's comprehensive efficacy of oil control, anti-oxidation and anti-photoaging.
The product has stable physical and chemical properties, no discoloration or activity loss in conventional cosmetic processing, non-sensitizing, non-toxic and harmless, free of heavy metal residues, passed multiple skin safety tests, especially suitable for oily and combination skin, and is a high-quality core raw material for high-end oil-control anti-aging skincare products.
Key Benefits
• Dual-phase Anti-oxidation, Exclusive for Oily Skin: High-purity flavonolignan complex, with both water-soluble and oil-soluble anti-oxidation activity. It targets lipid oxidation of oily skin, makes up for the single-phase defect of ordinary antioxidants, and realizes comprehensive skin anti-oxidation protection.
• Efficient Oil-control & Purifying, Improve Greasy Dullness: Inhibits sebum peroxidation and excessive oil secretion, improves facial greasy, shiny and pore-clogged state, refreshes skin texture, and maintains long-term water-oil balance.
• Powerful Anti-photoaging, Repair UV Damage: Effectively resists ultraviolet photoaging damage, relieves sunburn erythema, peeling and inflammatory pigmentation, repairs light-aged skin barrier, and reverses skin sun aging state.
• Mild Anti-inflammatory & Stabilize Skin: Gently inhibits inflammatory factor secretion caused by oil accumulation and UV stimulation, relieves oily skin redness and sensitivity, improves recurrent inflammatory skin problems, and stabilizes fragile skin.
• DNA Protection & Enhance Self-repair: Protects skin cell DNA from oxidative damage, enhances skin self-healing ability, inhibits abnormal tissue proliferation, improves rough texture, and delays skin aging.
• Excellent Compatibility & Industrial Stability: Good solubility and wide formula adaptability, can be freely compounded with various antioxidants and flavonoid 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 difference between silymarin and conventional flavonoid raw materials?
A1: Silymarin belongs to flavonolignan complex, with unique water-oil dual-phase antioxidant activity. Different from single water-phase antioxidant of ordinary flavonoids, it is specially effective for oily skin lipid oxidation, has stronger UV damage repair and oil-control balancing capabilities, and is the exclusive high-efficiency raw material for oily skin anti-aging maintenance.
• Q2: What is the recommended addition ratio of silymarin in skincare formulas?
A2: Conventional antioxidant maintenance products: 0.02%-0.1%; Oily skin oil-control purifying 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 silymarin cause formula yellowing or precipitation?
A3: High-purity silymarin is fine light yellow 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 silymarin suitable for compounding with?
A4: Silymarin has excellent formula compatibility. It can be perfectly compounded with quercetin, luteolin, kaempferol, vitamin C, ferulic acid and other ingredients to build a water-oil dual anti-oxidation system, which significantly improves the formula's oil control, anti-photoaging and anti-inflammatory repair efficacy.
• Q5: How to store silymarin 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 oil-control 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.
