Centella Asiatica Leaf Extract

Product Description

Green Stone Swiss supplies standardized Centella asiatica leaf extract with batch COA traceability and HPLC-defined triterpene markers for cica skincare programs. Direct factory sourcing supports flexible MOQ from lab trials to bulk liquid or powder drums.

Aerial leaf tissues deliver pentacyclic triterpenoid saponins—including asiaticoside and madecassoside—that modulate inflammatory mediators and support extracellular matrix remodeling in leave-on repair systems. CosIng recognizes this botanical part for skin conditioning in sensitive-skin and post-treatment care lines.

Formulators specifying leaf-only INCI declarations adopt this extract for K-beauty cica serums and gel creams—building triterpenoid stacks with isolated Centella actives while distinguishing leaf tissue sourcing from whole-herb or root-only centella grades.

Key Benefits & Applications

Centella asiatica leaf extract delivers leaf-enriched triterpenoid saponins for cica serums, gel creams, and post-treatment moisturizers targeting sensory discomfort and barrier support.

• Triterpene Soothing Modulation: Madecassoside-class saponins help calm visible redness and sensory irritation in sensitive-skin toners at 0.5–2% extract load.
• Collagen Pathway Support: Asiaticoside-rich leaf profile supports fibroblast collagen I and III expression in post-treatment repair gels and structural firming serums.
• Barrier Integrity Support: Triterpenic acids assist stratum corneum lipid organization and TEWL control in daily barrier-repair moisturizers and cica balms.

Formulation Guidelines

Centella asiatica leaf extract suits water-based leave-on systems where cica triterpenoid activity and sensitive-skin tolerance are priorities.

• Recommended use level: 0.5–2% in serums and gel creams; 0.3–1% in emulsions and masks.
• Optimal formula pH: 4.5–6.5 to preserve triterpene stability; avoid prolonged exposure above pH 7.0.
• Processing: Add during cool-down below 45 °C; pre-dissolve in glycerin or butylene glycol slurry.
• Compatibility: Compatible with panthenol, hyaluronic acid, and niacinamide; perform patch testing with strong acids at low pH.
• Caution: High extract load may tint clear gels amber—adjust packaging or combine with decolorizing carriers.
• Synergy: Formulators often co-add Asiaticoside at 0.1–0.5% to build TECA-style triterpenoid stacks in cica repair gels.
