1. Product Identity

Liposomal Vitamin C 80% is a high-loading encapsulated ascorbic acid powder produced via advanced liposomal technology. The active Vitamin C is enclosed within phospholipid bilayers, forming a protective delivery system that significantly improves stability and absorption.

• Active Content: ≥80% Vitamin C
• Entrapment Rate: ≥90%
• Appearance: Off-white to light yellow powder
• Composition: Vitamin C + phospholipids
• Shelf Life: 24 months
• Non-GMO / Allergen-Free

Designed for premium nutraceutical formulations, this ingredient delivers both potency and performance in finished products.

2. Liposomal Technology Mechanism

Unlike conventional Vitamin C, liposomal encapsulation integrates ascorbic acid into microscopic phospholipid vesicles. These structures mimic biological membranes, allowing efficient transport across intestinal barriers.

The phospholipid layer acts as a protective shield against oxidation, enzymatic degradation, and gastric acidity—ensuring that a higher percentage of Vitamin C reaches systemic circulation.

3. Dual Drying Technology Options

We offer two production routes to meet different formulation and cost requirements:

Spray Dried Liposomal Vitamin C

• Cost-effective for large-scale production
• Good flowability and dispersibility
• Suitable for tablets, capsules, and powders

Freeze Dried Liposomal Vitamin C

• Superior structural integrity of liposomes
• Higher retention of biological activity
• Ideal for premium and sensitive formulations

4. Carrier System Flexibility

Three phospholipid systems are available depending on formulation goals:

Sunflower Lecithin (Standard)

• Clean-label, allergen-friendly
• Widely used in nutraceutical applications

Sunflower Lecithin + Phytosterols

• Enhanced membrane rigidity
• Improved stability in complex formulations

Sunflower Lecithin + Cholesterol

• Stronger liposomal bilayer structure
• Suitable for high-stability or extended-release products

5. Bioavailability Enhancement Value

Vitamin C is water-soluble and highly sensitive to oxidation, leading to degradation during processing and low absorption efficiency.

Liposomal delivery solves these key challenges:

• Protects Vitamin C from oxidation and degradation
• Enhances intestinal absorption efficiency (2–5× higher)
• Reduces gastrointestinal irritation at high dosages
• Provides more sustained release in the body

This makes it especially valuable for high-dose or premium immune-support formulations.

6. Compliance & Export Support

We ensure smooth global supply with full documentation support:

• COA (HPLC-tested content & purity)
• Non-GMO Statement (sunflower-derived phospholipids)
• Allergen-Free Declaration
• Heavy metals & microbiological compliance
• Standard export documentation (COO, MSDS, etc.)

The product is typically declared as a plant-derived extract ingredient for export.

7. Application Scenarios

Liposomal Vitamin C 80% is widely used in:

• Functional beverages & solid drinks
• Capsules & tablets
• Effervescent powders
• Gummies and chewables
• High-end dietary supplements
• Customized nutraceutical blends

It is especially suitable for formulations targeting immune support, antioxidant protection, and skin health.

8. B2B Customization Capabilities

We provide flexible customization based on your formulation needs:

• Active content adjustment (different concentrations available)
• Encapsulation process selection (spray dried / freeze dried)
• Carrier system customization
• Particle size & solubility optimization
• Water-dispersible / instant soluble liposomes
• Co-encapsulation solutions (e.g., VC + Zinc / VC + Glutathione)
• Private label & bulk packaging options

FAQ – Liposomal Vitamin C 

1. How does liposomal Vitamin C differ from standard ascorbic acid?

Liposomal Vitamin C is encapsulated in phospholipids, which protect it from degradation and significantly improve absorption efficiency compared to regular Vitamin C.

2. What is the typical entrapment efficiency of your product?

Our Liposomal Vitamin C achieves an encapsulation rate of over 90%, ensuring effective delivery of active ingredients.

3. Which drying method should I choose for my product?

Spray drying is ideal for cost-sensitive, large-volume products, while freeze drying is recommended for high-end formulations requiring maximum activity retention.

4. Are your phospholipids allergen-free?

Yes, we use sunflower-derived phospholipids, which are naturally free from soy and common allergens.

5. Does the product fully dissolve in water?

It forms a stable colloidal dispersion rather than true dissolution, which is a normal characteristic of liposomal systems.

6. What stability performance can you guarantee?

Under proper storage conditions, the product maintains ≥80% Vitamin C content throughout its shelf life, demonstrating strong stability.

7. Can you support regulatory documentation for EU or US markets?

Yes, we provide comprehensive documentation including COA, Non-GMO, allergen statements, and export certificates to support compliance.

8. Can this ingredient be combined with other actives?

Yes, we offer co-encapsulation solutions and customized blends to enhance formulation efficiency and product differentiation.
