Description
LIPOSOMAL DELIVERY INGREDIENT
Liposomal Vitamin C (Ascorbic acid) Powder
Liposomal Vitamin C (Ascorbic acid) is supplied as a phospholipid-encapsulated powder for formulators who need the active dispersed in a lipid bilayer rather than as a free crystalline solid. This grade is offered as a B2B raw material: 50% ascorbic acid of the active on a phospholipid carrier, produced by thin-film hydration followed by high-pressure homogenisation and spray drying. It is intended for further processing by the buyer (capsules, stick packs, sachets, liquid or powder blends). The material is characterised by phospholipid identity, particle-size distribution and encapsulation-related parameters rather than by crystallinity, so the specification below is written accordingly.

Buyer Decision Guide
Liposomal grades are specified differently from plain powders. Buyers should agree on three things before approval: the carrier system (phosphatidylcholine from sunflower or soy lecithin, or a synthetic phospholipid), the declared active content of the encapsulated system, and the dispersion behaviour in the buyer’s own matrix. Confirm the intended final dosage form at enquiry stage.
- Active content: 50% ascorbic acid on a phospholipid carrier, expressed on the encapsulated system rather than on total powder mass.
- Carrier declaration: phosphatidylcholine source and phospholipid content are stated on the COA for identity control.
- Particle size: micro-dispersible powder, specification agreed against the dispersion test the buyer will run.
- Dispersion: designed to disperse in water and in oil-free aqueous matrices; evaluate in your own base before scale-up.
- Handling: hygroscopic, sensitive to heat and oxygen; keep sealed, cool and dry, and open only under controlled conditions.
- This material is a raw material for further processing, not a finished consumer product.
How This Grade Differs
Liposomal Vitamin C (Ascorbic acid) is not interchangeable with plain Vitamin C (Ascorbic acid) powder on a weight-for-weight basis. The active is held in a phospholipid bilayer, so the declared content refers to the encapsulated system, and the material behaves differently in dispersion, taste masking and flow. Buyers comparing quotations should normalise on the active content stated on the COA, not on the price per kilogram of powder.

Frequently Asked Questions
Which batch is the quotation based on?
The page cites representative batch LXLP260421; the current lot’s certificate governs release.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
Is the declared percentage a specification limit or a measured result?
The specification figure is 50.0%; the measured result for your lot is reported separately on its COA.
How does the material behave in your process?
It is supplied as Fine off-white to pale cream powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
