Description
LIPOSOMAL DELIVERY INGREDIENT
Liposomal Glutathione (reduced) Powder
Liposomal Glutathione (reduced) 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: 70% reduced glutathione 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: 70% reduced glutathione 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 Glutathione (reduced) is not interchangeable with plain Glutathione (reduced) 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.
