Liposomal Alpha Lipoic Acid

Description of Liposomal Alpha Lipoic Acid

Liposomal alpha-lipoic acid (ALA) API (active pharmaceutical ingredient) is a specialized formulation where alpha-lipoic acid, a naturally occurring organosulfur compound, is encapsulated within phospholipid-based liposomes to serve as a raw material for pharmaceutical or nutraceutical products.

Chemically, ALA (C₈H₁₄O₂S₂, 1,2-dithiolane-3-pentanoic acid) is a chiral molecule with a five-membered disulfide ring, exhibiting amphiphilic properties due to its ability to dissolve in both aqueous and lipid environments, though its stability is sensitive to heat and oxidation. The liposomal encapsulation, typically utilizing phosphatidylcholine, forms a dry or semi-dry powder or granular matrix, enhancing ALA’s resistance to degradation.

Physically, this API appears as a pale yellow to off-white powder, with a faint sulfurous odor characteristic of ALA’s thioctic structure, and its fine texture reflects the microscale liposomal vesicles. The liposomal coating improves ALA’s dispersibility and protects its reactive disulfide bond, making it a robust ingredient for downstream formulation into supplements or therapeutics. As a leading API manufacturer, WBCIL prioritizes strict CGMP and ISO quality control measures throughout the production process. The prolonged experience from 1962 ensures consistent potency, purity, and safety in every dose of WBCIL’s liposomal alpha lipoic acid.
