As the life-science division of Zhonghong Group, Exbiol® leverages 29 years of phytochemical engineering to provide premium Centella Asiatica Extract bulk supply. For Sourcing Managers, we resolve the “Supply Lead-Time Crisis” with a 10,000kg ready-stock inventory for 3-day global dispatch. For R&D Giant-level demands, we offer standardized TECA (Total Extract of Centella Asiatica) containing 95% Triterpenes (Asiaticoside, Madecassoside, Asiatic Acid, Madecassic Acid). Our GMP-certified facility ensures zero batch-to-batch volatility, providing full molecular fingerprinting and audit-ready documentation (MSDS, TDS, COA) for Tier-1 dermaceutical leaders.
1. What is Centella Asiatica Extract?
Centella Asiatica Extract, often termed Gotu Kola or Cica, is a botanical active standardized for its pentacyclic triterpenoid content. In industrial skincare and pharmaceuticals, it is recognized for its “Cica-Repair” functional properties. At Exbiol®, we produce a purified extract that isolates the four key biomarkers: Asiaticoside, Madecassoside, Asiatic Acid, and Madecassic Acid, ensuring a high-potency raw material for professional barrier-repair and collagen-support formulations.
2. Technical Specifications Table
| Technical Parameter | Standard / Specification |
|---|---|
| Active Content (HPLC) | Total Triterpenes ≥ 10.0% – 95.0% (TECA) |
| Marker Compound Ratio | Asiaticoside : Madecassoside (Optimized 40:60) |
| Solvent Residue | Ethanol Only < 5000 ppm (No Methanol) |
| Loss on Drying | ≤ 5.0% |
3. Source & Botanical Origin
Our raw material is sourced from high-humidity tropical wetlands in Southeast Asia and processed in our Shaanxi industrial hub. We select only the aerial parts of the Centella asiatica (L.) Urb. to ensure peak triterpene accumulation. Every harvest undergoes DNA barcoding to verify species authenticity, preventing adulteration with common swamp weeds.
4. Mechanism of Action
The molecular mechanism involves the stimulation of TGF-β signaling. Asiaticoside and Madecassoside promote the synthesis of Type I and III collagen within human fibroblasts. Additionally, the acidic components (Asiatic and Madecassic acids) may support the functional property of matrix metalloproteinase (MMP) inhibition, protecting the skin’s extracellular matrix from degradative aging.
5. Application Benefits
- Skin Repair: May support the functional property of epidermal barrier restoration.
- Soothing: Functional property for reducing oxidative stress in sensitive skin.
- Collagen Booster: High-purity TECA provides a significant functional property for anti-wrinkle efficacy.
6. Usage & Formulation Guide
Recommended Dosage: 0.1% – 1.0% (Standardized 10% powder); 0.1% – 0.5% (High-purity TECA).
pH Stability Matrix: Stable between pH 4.5 and 7.5. Best results achieved in slightly acidic to neutral emulsions.
Solubility: Our CWD Grade (Cold Water Dispersible) is designed for instant dissolution in aqueous serums. Standard TECA is soluble in ethanol and propylene glycol.
7. Industrial Evolution
The market has evolved from crude Gotu Kola juice to Purified Triterpene Isolate (TECA). Exbiol® represents the fourth generation of this evolution, utilizing Multi-column chromatography to remove plant chlorophyll and heavy metals, providing a white-to-off-white powder that does not discolor final cosmetic formulations.

9. Manufacturing Flow Description
Harvesting (Aerial Part) → Cold-Water Washing → Ethanol Extraction (70% v/v) → Centrifugal Filtration → Macroporous Resin Chromatography → Concentration → Decolorization → Spray Drying → Micronization (80 Mesh) → Vacuum Sealing.
10. Storage & Packaging
Bulk Packaging: 25kg card-board drum with double PE inner liners.
Storage Conditions: Store at <25°C, humidity <60%. Centella is highly hygroscopic; ensure airtight sealing after every use. Shelf life: 24 months.
11. MOQ, Sample & Global Shipping
- MOQ: 1kg for R&D trials; 25kg for bulk industrial orders.
- Samples: 10g-50g free sample for lab evaluation.
- Logistics: Fast dispatch to EU/USA via Air Freight (DHL/FedEx) or Temperature-controlled Sea Freight.
12. Clinical Data & Scientific Research
In-vivo studies on TECA demonstrate a 30% increase in hydroxyproline levels in dermal tissue over 8 weeks, indicating functional property support for collagen architecture. Comparative studies show that Madecassoside specifically reduces post-procedure erythema significantly faster than standard panthenol-based creams.
13. Applicable Industries
Wound Care OEM
Health Supplements
14. B2B Application Scenarios
Exbiol® bulk supply is optimized for Contract Manufacturers (OEM/ODM) developing “Cica-creams,” transparent soothing gels, and post-sun recovery lotions requiring high-purity, low-ash actives.
15. Industry Market Scenarios
For brands targeting the Clean Beauty and Hypoallergenic markets, our Centella Extract provides the verified safety profile needed to pass dermatologist-testing and sensitivity audits in the EU and USA.
16. Supplier Comparison & Procurement Guide
Buyer Check: Ash Content & Color Stability.
Low-grade Centella extracts often have ash levels >10% and a dark brown color that discolors creams. Exbiol® ensures ash content <5% and a stable off-white color profile, reducing formulation risk for Tier-1 brands.
17. Technical FAQ for Bulk Buyers
Q: What is the difference between Gotu Kola Powder and TECA?
