Description

Phosal 50 Pg is a high-purity phospholipid-based excipient, identified by CAS No. 774594-96-6. This specialized compound is engineered to enhance the solubility and bioavailability of active pharmaceutical ingredients, addressing a key challenge in modern formulation science. It is an essential component for pharmaceutical and nutraceutical manufacturers developing advanced lipid-based delivery systems, such as self-emulsifying drug delivery systems (SEDDS) and liposomal formulations.

Application

• As a critical solubilizer and emulsifier in oral lipid-based drug delivery systems (e.g., SEDDS, SMEDDS).
• For the formulation of parenteral nutrition emulsions and intravenous lipid injectables.
• As a key phospholipid component in the manufacture of liposomes and niosomes for targeted drug delivery.
• In nutraceutical and cosmeceutical products to improve the absorption of fat-soluble vitamins (A, D, E, K) and actives.
• As a bioavailability enhancer for poorly water-soluble drugs in solid dosage forms.
• Used in diagnostic imaging agents as a stabilizing agent for contrast media.
