PEG 1500 is a waxy solid polyethylene glycol used as a hydrophilic base and carrier in suppositories, ointments, gels, and solid dispersions.

It offers higher melting point and hardness than PEG 1000, enabling tailored release and mechanical strength.

PEG 1500 dissolves readily in water, assisting rapid dissolution and drug release from dosage forms.

It is compatible with many APIs and can be blended with other PEGs or lipids to fine-tune melting behavior and texture.

Commonly used where clean handling, low volatility, and good patient acceptability are required.
