Medical uses

PEG is the basis of a number of laxatives (e.g., macrogol-containing products, such as Movicol and polyethylene glycol 3350, or SoftLax, MiraLAX, ClearLAX, Osmolax, or GlycoLax). Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy. 

Chemical uses

Polyethylene glycol has a low toxicity and is used in a variety of products.[19] The polymer is used as a lubricating coating for various surfaces in aqueous and non-aqueous environments.

Since PEG is a flexible, water-soluble polymer, it can be used to create very high osmotic pressures (on the order of tens of atmospheres). It also is unlikely to have specific interactions with biological chemicals. These properties make PEG one of the most useful molecules for applying osmotic pressure in biochemistry and biomembranes experiments, in particular when using the osmotic stress technique.

Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluid in electronic testers.

PEG has also been used to preserve objects that have been salvaged from underwater. In addition, PEG is used when working with green wood as a stabilizer, and to prevent shrinkage. 

PEG is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning.

PEG derivatives, such as narrow range ethoxylates, are used as surfactants.

PEG has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.
