Centella Asiatica Extract Powder

Shaanxi Rebecca Biotechnology Co., Ltd. integrates R & D, production and global supply capacity. We use proprietary high temperature drying and ultra fine grinding processes to maximise the bioactivity of botanical components. Our rigorous quality control systems and third party testing processes will benefit you ensuring that each batch is manufactured to worldwide standards like as ISO9001, HALAL, KOSHER and HACCP.

Our logistics network safely delivers products all over the world. We can provide OEM/ODM customisation for your unique formulation needs, whether it be powder, pills, capsules or other dosage forms. Our team offers technical assistance during the development process to help you get the best performance of your product.

We harvest entire plants of Centella Asiatica Extract Powder, including aerial stems, leaves and roots from mature disease free crops. Mouldy, wilted or contaminated material is removed by manual sorting before low temperature drying. The storage conditions avoid oxidation of saponin.

Three raw material grades are available for different applications:

Standard Extraction Grade: Routine pesticide control for standard quality, general-purpose formulations.

High Purity Refined Grade: High purity refined grade is produced from selected clean raw materials with pre-extraction screening of heavy metals and pesticides and is suitable for high concentration triterpene requirements.

Grade for Export Traceability: Full planting and processing records Dedicated extraction lines Suitable for EU and US regulatory clearances

Solubility Profile

Standard extract It is freely soluble in hot water and in ethanol, somewhat soluble in cold water. Turbidity may occur in cold water applications. Our modified cyclodextrin form is freely soluble in hot and cold water and shows no precipitation.

Thermal Stability

Keep processing temperatures under 65 degrees C. If it is kept at temperatures above 80 °C for a long time the triterpenes break down and the colour gets darker.

pH Range

Stable at pH 4.0–7.3. Strong acids or alkali destroy the saponin structure.

Light Sensitivity

Powder is stable if sheltered from light and packed airtight. Aqueous liquids oxidise in the presence of light.

Control of Moisture

Hygroscopicity increases with higher amount of triterpenes. Shelf life 24 months vacuum sealed aluminium foil bags and moisture proof drums.

Preparation of Raw Material

The whole plants are sorted, washed and dried at low temperature (40-45 °C). A pulverisation to 20-30 mesh boosts the extraction efficiency.

Ethanol-Water Extraction

The materials are loaded into sealed tanks for 2-3 step extraction using food-grade ethanol-water solution. Filtration is a solids separation process from mixed extract filtrate.

Concentration and De-Alcoholizing

Ethanol recovery and concentrated extract is produced by negative pressure and low temperature concentration below 65 °C.

Purification of Resin (Critical Step)

Macroporous resin columns remove sugars, salts, proteins and colours. Gradient ethanol elution for enrichment of triterpenes:

· 10% specification: Basic purification

· 20% specification: Single-pass refinement

· 40% specification: Multi-stage cascade elution

Decolorising and Refining

Dark contaminants are removed by secondary vacuum concentration and treatment with activated carbon.

Spray-Drying

Uniform powder is produced by high pressure atomisation with controlled temperature drying.

Modification of cyclodextrin (optional)

The introduction of β-cyclodextrin increases the solubility in cold water via high-pressure homogenisation and spray-drying.

Finishing

Batch homogeneity is achieved by grinding, 80–100 or 200 mesh screening and three-dimensional mixing, followed by vacuum-seal packaging and full testing.

Cosmetic Formulations

Your products will have increased collagen synthesis, faster wound healing and decreased inflammation. Good for post procedure skin care, anti ageing creams and sensitive skin treatments.

Pharmaceutical Uses

Supports cognitive function, circulation, and reinforces capillary walls. Applied in dietary supplements and topical treatments.

Functional Foods

Offers antioxidant and anti-inflammatory benefits for health beverages and nutraceutical goods.

We hold certifications such as ISO9001, ISO22000, FSSC22000 and cGMP. Each batch is tested for content, heavy metals, pesticide residues and microbiological. Third-party lab verified purity and potency. Full traceability paperwork is provided with every shipment in accordance with EU EC396 and EU 2023/915.

Standard Packaging

Inner layer: Vacuum-sealed aluminum foil bag

Outer layer: 25kg moisture-proof cardboard drum

Custom Options

We accommodate special packaging requirements, dosage forms, and labeling specifications.

Shipping Methods

FedEx, DHL, air freight, or sea freight depending on order size and destination.

Q: How do you control microbial counts for cosmetic applications?

A: We use closed extraction methods, sterile filtering and low temperature spray drying to keep microbiological levels at cosmetic grade specifications.

Q: Does your extract precipitate out of cold liquid formulations?

A: Standard grade may precipitate on chilling. Our improved, water soluble, variant inhibits precipitation during extended term cold storage.

Q: What is your MOQ?

A: MOQ is negotiable. We provide formulation testing samples either free or paid before large orders.

Q: Can you offer price protection for framework orders?

A: We provide long-term customers preferred pricing and fixed-price periods to shield them from volatility in raw materials.
