Sophora Japonica Extract

Product Description

Our Sophora Japonica Extract is high-purity botanical material from direct factory supply, extracted from authenticated Sophora japonica L. with batch COA traceability for antioxidant and soothing skincare formulators.

Standardized rutin, quercetin, and flavonoid glycosides scavenge ROS, modulate tyrosinase activity, and calm inflammatory mediators in aqueous serums without isolated synthetic flavonoid load.

CosIng-listed pagoda tree extract meets demand for rutin-dense calm-actives in urban-defense and tone-evening care, offering multi-flavonoid depth beyond single-compound rutin powders.

Key Benefits & Applications

Sophora Japonica Extract delivers rutin-quercetin flavonoids for formulators building soothing, antioxidant, and tone-evening skincare systems.

• Rutin and quercetin flavonoids scavenge ROS and limit oxidative stress in daily antioxidant day serums.
• Sophora flavonoid complex modulates tyrosinase activity for tone-evening water-based essences and brightening gels.
• Calms inflammatory mediators in sensitive-skin recovery and post-treatment soothing formulas.
• Soothes redness-prone reactive skin in calming mists, after-sun gels, and daily moisturizers.
• Rutin supports capillary comfort and reduces visible redness in couperose-prone treatment creams at 0.5–5%.

Formulation Guidelines

Use at 0.5–5% w/w in water-based soothing and antioxidant systems; maintain pH 4.0–7.0 and add below 40°C to preserve rutin markers.

• Recommended use level: 0.5–5% in serums, essences, toners, and calming creams.
• Optimal formula pH: 4.0–7.0 to stabilize rutin and quercetin flavonoids.
• Add during cool-down below 40°C after emulsification to limit heat degradation.
• Compatible with niacinamide and panthenol in aqueous anti-redness bases.
• Pre-dissolve in glycols for improved dispersion in water-based systems.
• Synergy: Niacinamide complements rutin flavonoids for stacked tone and barrier support in daily essences.
