What is the melting point of PEG 4000 and its typical formulation use?
PEG 4000 has a melting point of approximately 50–58°C. It is commonly used alone or blended with PEG 1500 or PEG 6000 to create water-soluble suppository and pessary bases, and is also used as a plasticiser and pore-former in tablet film coating formulations.
How is PEG 4000 used in solid dispersion technology?
PEG 4000 is a widely studied carrier for solid dispersions used to enhance the dissolution rate and bioavailability of poorly water-soluble drugs. The API is dispersed at a molecular or amorphous level within the PEG 4000 matrix, typically via melt or solvent methods, significantly improving wetting and dissolution compared to the crystalline drug alone.
Is PEG 4000 hygroscopic and how should it be stored?
PEG 4000 has low to moderate hygroscopicity compared to lower molecular weight PEGs. It should be stored in tightly sealed containers in a cool, dry area to prevent moisture uptake, which can affect powder flow and processing consistency.
