Polygonum Multiflorum Root Extract

Product Description

Our standardized Polygonum Multiflorum Root Extract is derived from authenticated He Shou Wu root under GMP-aligned processing with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes.

THSG and stilbene glucoside markers—quantified by HPLC—scavenge reactive oxygen species, modulate inflammatory signaling, and support follicular microenvironment balance, linking traditional root use to modern hair tonic, scalp-repair, and anti-aging care systems.

Unlike generic botanical blends, this CosIng-listed Polygonum multiflorum root suits TCM-inspired hair-revival and scalp-vitality lines where formulators want traceable stilbene assays with high-purity direct factory supply.

Key Benefits & Applications

This root extract supports hair vitality, antioxidant, and scalp-comfort claims through stilbene-rich Polygonum multiflorum suited to hair tonic and anti-aging formulators.

• Hair Growth Stimulation: Stilbene markers help support follicular microenvironment balance in leave-on scalp serums and hair tonics.
• Hair Bonding & Repair: Root phytocomplex supports shaft resilience and manageability in conditioning treatments and hair masks.
• Antioxidant Protection: THSG and polyphenols neutralize oxidative stress in scalp and anti-aging skin care formulas.
• Anti-Aging Defense: Helps limit matrix-degrading enzyme activity in mature-scalp and photo-exposed skin treatment emulsions.
• Anti-Inflammatory Modulation: Calms irritated scalp conditions in sensitive daily-care shampoos and soothing tonics.

Formulation Guidelines

Introduce standardized Polygonum root extract in hydroalcoholic or aqueous phases; confirm stilbene assay and preservation for water-rich hair systems.

• Suggested use level: 1–5% w/w in scalp serums and hair tonics; 0.5–2% in shampoos (Typical).
• Processing: Pre-dissolve in ethanol, glycerin, or water before adding to water phase at 30–40°C.
• pH window: Maintain 4.5–7.0; stilbene stability best in mildly acidic to neutral systems (Typical).
• Compatibility: Works with ginseng, drynaria, and panthenol extracts; avoid prolonged heating above 80°C.
• Preservation: Requires broad-spectrum preservation in leave-on scalp and facial water-based formulas.
• Synergy: Pair Drynaria Fortunei Root Extract at 1–3% with Polygonum root in TCM hair-revival scalp essences.
