Populus Nigra Bark/Bud/Leaf/Twig Extract

Product Description

Our Populus Nigra Bark/Bud/Leaf/Twig Extract is high-purity botanical material from direct factory supply, sourced from authenticated Populus nigra L. aerial parts with batch COA traceability for formulators building antioxidant and soothing cosmetic lines.

Caffeic acid, p-coumaric acid, flavonoids, and salicin precursors scavenge ROS, modulate inflammatory mediators, and support gentle cell renewal in aqueous systems without synthetic salicylate load.

CosIng-listed black poplar extract aligns with K-beauty first-essence and post-treatment care trends, offering poplar-bud phenolic depth beyond generic tree bark powders.

Key Benefits & Applications

Populus Nigra Extract delivers poplar-bud phenolic actives for formulators building antioxidant, soothing, and gentle-renewal skincare systems.

• ROS scavenging via caffeic and p-coumaric phenolics supports antioxidant day serums and essences.
• Flavonoid-rich profile modulates inflammatory mediators in reactive-skin recovery and post-treatment formulas.
• Salicin precursors enable gentle cell turnover in problem-skin toners at 1–3% without harsh acid load.
• Poplar bud phenolics defend against photo-aging triggers in UV-exposed daily care and SPF adjunct systems.
• Conditions and calms redness-prone skin in hydrating mists and first-essence treatment lines.

Formulation Guidelines

Use at 1–5% w/w in water-based soothing and antioxidant systems; maintain pH 4.0–6.5 and add below 40°C to preserve salicin and phenolic markers.

• Recommended use level: 1–5% in essences, toners, and lightweight serums.
• Optimal formula pH: 4.0–6.5 to stabilize salicin and flavonoid actives.
• Add during cool-down below 40°C after emulsification to limit heat degradation.
• Compatible with panthenol and hyaluronic acid in aqueous calming bases.
• Avoid high-level strong acids or oxidizers that may destabilize phenolic compounds.
• Synergy: Pair Niacinamide at 2–5% with poplar phenolics to calm reactive skin in post-treatment essences.
