Polyethylene Glycol 1500: Hydrophilic Carrier for Suppositories and Topicals
Polyethylene Glycol 1500 (PEG 1500) is a semi-solid grade polyethylene glycol that melts at approximately 44–48°C. It is widely used in pharmaceutical formulation as a base for suppositories and topical preparations where a water-soluble, non-greasy vehicle is required. PEG 1500 blends readily with both liquid and solid PEG grades, allowing formulators to fine-tune consistency and melting behaviour.

Formulation Applications
PEG 1500 is a standard component of compendial PEG suppository bases, typically blended with PEG 6000 to achieve the proper firmness and release characteristics. In topical ointments, it serves as the intermediate-molecular-weight component in water-soluble bases that can be washed off without residue. It is also used as a fusion carrier in solid dispersion formulations aimed at improving the dissolution rate of poorly water-soluble drugs. Its compatibility with a wide range of active ingredients makes it a dependable formulation building block.
