Morus Nigra Leaf Extract

Product Description

Our standardized Morus Nigra Leaf Extract is sourced from authenticated black mulberry foliage and processed under GMP-aligned controls with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes.

Chlorogenic acid, DNJ, and flavonoid markers—quantified by HPLC—modulate tyrosinase-linked melanin pathways and scavenge reactive oxygen species, supporting brightening, dark-spot, and tone-evening claims in aqueous serums and emulsions.

Unlike Morus alba-focused whitening narratives, this CosIng-listed Morus nigra leaf extract suits clean-label brightening portfolios where formulators want traceable polyphenol assays with high-purity direct factory supply.

Key Benefits & Applications

This leaf extract supports brightening, tone-evening, and antioxidant claims through polyphenol-rich Morus nigra suited to spot-care and daily brightening formulators.

• Tyrosinase Inhibition: Mulberry polyphenols help modulate tyrosinase-linked melanin synthesis in brightening serums and essences.
• Dark Spot Correction: Supports targeted hyperpigmentation care in spot treatments and concentrated ampoules.
• Even Skin Tone: Promotes uniform complexion appearance in daily tone-balancing emulsions and toners.
• Whitening & Brightening: Delivers radiance-oriented claims in clean-label brightening and glow-focused skin care lines.
• Antioxidant Protection: Chlorogenic acid and flavonoids neutralize oxidative stress in daytime UV-exposed brightening formulas.
• Anti-Inflammatory Modulation: Calms post-UV irritation in sensitive-skin brightening and after-sun recovery gels.

Formulation Guidelines

Introduce standardized Morus nigra leaf extract in aqueous or hydroalcoholic phases; verify polyphenol assay and preservation for water-rich brightening bases.

• Suggested use level: 1–5% w/w in brightening serums; 0.5–2% in daily emulsions (Typical).
• Processing: Pre-dissolve in glycerin, propylene glycol, or ethanol before adding to water phase at 30–40°C.
• pH window: Maintain 4.0–6.5; polyphenol stability best in mildly acidic systems (Typical).
• Compatibility: Works with niacinamide and alpha arbutin; avoid strong oxidizers that degrade flavonoids.
• Preservation: Requires broad-spectrum preservation in water-rich leave-on brightening formulas.
• Synergy: Pair Niacinamide at 2–5% with mulberry leaf polyphenols in brightening essences for dual tyrosinase and transfer control.
