Morus Nigra Leaf Extract

Product Description

Our high-purity Morus Nigra Leaf Extract is standardized from Morus nigra L. leaves through controlled hydro-ethanol extraction at direct factory facilities, with batch COA traceability and typical flavonoid profiling available on request.

Rutin, chlorogenic acid, and related polyphenols inhibit tyrosinase-linked melanogenesis, scavenge ROS, and support anti-glycation defense, while mild phenolic activity helps calm redness-prone skin in aqueous systems stable for cosmetic use.

Unlike isolated synthetic brighteners, this CosIng-listed black mulberry matrix suits brightening essences, tone-correcting serums, and antioxidant day mists where formulators need traceable botanical actives with consistent B2B bulk supply.

Key Benefits & Applications

This black mulberry leaf extract delivers flavonoid-driven brightening, antioxidant, and calming benefits for daily care and targeted tone-correction lines.

• Flavonoid-mediated tyrosinase pathway modulation supports brightening essences and spot-care gels at 1–3% w/w.
• Polyphenol antioxidant activity helps neutralize ROS in UV-exposed day serums and antioxidant mists.
• Tone-unifying support for dull, uneven complexions in treatment lotions and radiance-boosting emulsions.
• Phenolic anti-glycation defense aids mature-skin anti-aging creams targeting glycation-linked dullness at 2–4%.
• Mild anti-inflammatory profile suits post-exposure soothing toners and sensitive-skin calming essences.

Formulation Guidelines

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

• Suggested use level: 1–5% w/w in serums, essences, toners, and emulsions.
• Add during cool-down below 40°C to preserve flavonoid stability (Typical).
• Pre-disperse in glycerin or propanediol before adding to the aqueous phase.
• Maintain formula pH 4.0–6.5; avoid strong oxidizers and high-peroxide bleaching systems.
• Perform compatibility testing with metal ions and strong chelators above 3% load.
• Synergy: Pair Niacinamide at 2–5% with this extract to stabilize melanin transfer control in brightening essences.
