PEG 1000 is a semi-solid polyethylene glycol used as a base, plasticizer, and solubilizer in pharmaceutical and cosmetic formulations.

It is suitable for suppositories, ointments, creams, and solid dispersions of poorly soluble drugs.

PEG 1000 melts at relatively low temperature, providing smooth texture and controlled release profiles.

It is miscible with many hydrophilic excipients and compatible with a wide range of APIs.

Its consistent quality and low toxicity support broad use in regulated dosage forms.
