Liposomal Curcumin Powder

Liposomal Curcumin Powder – High-Absorption Encapsulated Curcumin for Premium Supplement Formulations

Shaanxi Hongda Phytochemistry Co., Ltd. is a manufacturer and supplier of plant-based nutraceutical ingredients, and our Liposomal Curcumin Powder is one of our most technically sophisticated products. The product has an encapsulation efficiency of ≥80% (Food Grade) and ≥90% (Pharmaceutical Grade), a particle size of 100-200nm and curcuminoids standardised to 95% purity directly addressing the low bioavailability issue that has long hampered conventional curcumin in supplement applications. It is ready for global B2B supply with ISO, Halal, Kosher, FSSC22000 and Organic Certifications.

Product Introduction

One of the most studied botanical actives in the supplement market is curcumin. The main disadvantage of raw curcumin is its water solubility of only 0.6 µg/mL and it quickly gets removed before absorption.

Liposomal Curcumin Powder addresses this issue by encapsulating active curcuminoids within phospholipid bilayers, generating nano-scale vesicles (liposomes) that mirror the shape of biological cell membranes. This permits the curcumin to enter cells via endocytosis, avoiding digestive degradation.

The phospholipids we utilise come from non-GMO sunflower or soy lecithin, which is very high in Phosphatidylcholine (PC). This provides a stable, water dispersible powder, which on reconstitution, forms a uniform colloidal suspension free from sedimentation.

Third-Party Test Report

Every batch is tested before it is shipped. Shaanxi Hongda engages with approved third-party agencies as SGS, Eurofins to verify:

· HPLC Assay — Confirms total curcuminoid concentration and ratio of Curcumin, Demethoxycurcumin and Bisdemethoxycurcumin

· DLS Analysis — confirms particle size distribution and PDI

· Encapsulation Efficiency (EE%) – determined to confirm ≥80% or ≥90% depending on grade

· Residual Solvents — validated ethanol levels at <5,000 ppm per USP <467>

· Heavy Metals & Microbiological Safety – tested to international standards

• Pesticide Residue Detection – complete panel screening

TEM (Transmission Electron Microscopy) photos are provided for visual confirmation of spherical Liposome integrity upon request.

Certificate of Analysis (COA)

Every shipment is accompanied by a comprehensive COA including:

· Appearance, colour and smell

· Particle size and PDI

· Encapsulation efficiency

· HPLC test for curcuminoids

·Ash, moisture and bulk density

· Heavy metals (Pb, Cd, As, Hg)

· Microbial count (TPC, Yeast, Mould, E.coli, Salmonella)

· Residual solvents

COA documents are traceable and batch specific. We may provide you with a sample COA for review prior to placing your transaction.

Liposomal Curcumin Powder Advantages

Higher bioavailability than standard curcumin extract

The liposomal shape allows direct cellular uptake via endocytosis. This skips first pass liver metabolism and prevents stomach acid from destroying curcumin – something not totally achievable with piperine-enhanced products.

Pharmaceutical-grade encapsulation efficiency

Our pharmaceutical grade solution has an encapsulation efficiency of ≥90%. This means more active curcumin is absorbed into the bloodstream, not wasted in the intestines.

Excellent water dispersibility.

The amphiphilic phospholipid coating permits the powder to be suspended colloidally in water. No grainy texture, no quick precipitation – suitable for beverage and functional food applications.

Better flavour profile

The unpleasant metallic taste of raw curcumin is hidden by the lipid coating. This makes it perfect for gummies, chewables and Sachets where palatability is a concern.

Stability throughout the long term

Electrostatic repulsion prevents the particles from aggregating when the zeta potential is <-30mV. The dry powder form removes water activity limiting oxidation of lipids -- 24 month shelf life.

Liposomal Curcumin Powder Application

Functional beverages and RTD drinks

The water-dispersible form can be easily added to recovery beverages, wellness shots and quick powders. It is stable over a range of pH values and does not cloud or separate.

Sports nutrition products

This chemical is included in post-exercise recovery solutions that tackle exercise-induced inflammation and oxidative damage at the cellular level. Higher plasma concentrations imply performance-support benefits are observed at lower dosages.

Brain & Joint Health Supplements

This format is perfect for joint support capsules, senior nutrition powders and cognitive health formulae as the absorption is clinical grade. The lipid masking also adds compliance in medicinal food applications.

Capsules, pills and gummies

The flowable powder format is compatible with many formulations including hard capsules, softgels, compressed tablets and gummy formulations without additional processing obstacles.

Production Process

Shaanxi Hongda adopts a controlled liposome formation technique in a purified workplace with a level of 100,000:

1. Raw Material Sourcing – Curcuma longa root extract, standardised to 95% curcuminoids Non-GMO phospholipids

2. Hydration & Mixing – Phospholipids are hydrated at controlled temperature to create lipid bilayers.

3. Encapsulation - Lipid vesicles for loading of curcuminoids by high-shear or ethanol injection method

4. Homogenization for Particle Size Reduction - 100–200nm particle size

5. Spray Drying - Liquid liposome solution transformed into stable flowable powder

6. QC Testing- EE%, DLS, HPLC, Microbiology, Residual Solvents Verified each batch

7. Packaging — 1 kg/bag or 25 kg/drum, double-layer PE bag with fibre drum

FAQ

Q1. What is the difference between Food Grade and Pharmaceutical Grade?

A: Food Grade is ≥80% encapsulation efficiency. Pharmaceutical Grade is ≥90%. Recommended for clinical nutrition, medical food or high potency supplement applications requiring optimum absorption, pharmaceutical grade.

Q2: How do I know the product is not merely a mixture of lecithin and curcumin but is actually liposomal?

A: Ask your provider for a report on Encapsulation Efficiency and TEM pictures. EE < 40% or the lack of spherical formations in TEM images implies a basic physical mixing and not real liposomal encapsulation.

Q3: Is this product water soluble?

A: It disperses in water. The liposomes form a persistent colloidal suspension in water which is a homogenous milky liquid, compared to the fast sedimentation of the raw curcumin powder.

Q4: How should I store the product?

A: Store in a sealed container in the dark at 2-25°C. Shelf life under these conditions is 24 months. Dry powder form minimises the danger of oxidation compared to liquid liposomal products.

Q5: Can I get samples prior to large order?

A: Yes. 20-100g sample packing is offered in aluminium foil packs. Send us your application data and we will arrange samples without delay.

Q6: What solvents are utilised in manufacturing and are residuals tested?

A: Residual solvents are tested according to USP <467> with limits for ethanol of <5,000 ppm. The COA contains complete residual solvent data.
