Drynaria Fortunei Rhizome Extract

Product Description

Our high-purity Drynaria Fortunei Rhizome Extract is standardized from Drynaria fortunei (Kunze) J.Sm. rhizome via controlled hydro-ethanol extraction at direct factory facilities, with batch COA traceability and typical naringin and flavonoid profiling available on request.

Naringin, hesperidin, and flavan-3-ol proanthocyanidins scavenge ROS, inhibit elastase linked to matrix degradation, and deliver CosIng-listed skin-protectant support, helping defend photo-exposed skin and calm irritation-prone complexions in aqueous systems.

Unlike generic fern botanicals with undefined polyphenol profiles, this traceable Gu-Sui-Bu matrix suits firming serums, antioxidant day emulsions, and barrier-repair creams where formulators need naringin-indexed rhizome actives with consistent B2B bulk supply.

Key Benefits & Applications

This Gu-Sui-Bu rhizome extract delivers naringin-driven antioxidant, elastase-modulating, and skin-protectant benefits for firming and barrier-support care lines.

• Naringin-rich flavonoid ROS scavenging supports antioxidant day serums and facial mists at 0.5–3% w/w.
• Elastase-inhibiting flavan-3-ol matrix defense in firming treatment creams and contour-sculpting gels at 1–3%.
• UV-stress photo-defense support in daytime protective emulsions and environmental-shield lotions.
• Visible fine-line reduction in anti-wrinkle eye-area concentrates and daily firming essences.
• CosIng-listed skin-protectant activity aids compromised barrier repair lotions and post-treatment recovery balms.
• Phenolic anti-inflammatory calming suits post-exposure soothing toners and sensitive-skin emulsions.

Formulation Guidelines

Apply standard plant-extract handling for stable incorporation into water-based cosmetic systems.

• Suggested use level: 0.5–3% w/w in serums, emulsions, toners, and eye-area products.
• Add during cool-down below 45°C to preserve naringin and flavonoid stability (Typical).
• Pre-disperse in glycerin or propanediol before adding to the aqueous phase.
• Maintain formula pH 4.5–6.5; avoid strong oxidizers and high-alkaline systems above pH 7.
• Perform compatibility testing with high-load metal ions and strong chelators above 2% extract level.
• Synergy: Layer Ascorbyl Glucoside beneath naringin-rich Drynaria for stacked antioxidant defense in firming day serums.
