Description:

Polyethylene glycol (PEG) is a polymer made for ethylene oxide. It comes in almost any MW, from 200 to 60,000. 400 to 12,000 are the most common with 400 the most common for liquids and 2,500 for solid. (Anything over 800 to 1,000 is a solid at room temp.) It is nontoxic at any reasonable level. It is nonpolar while having lots of hydroxyl functionality. This makes it great for getting things to stay soluble in oil. Used a lot for compatibility reasons. Can also be used as a painless vehicle, instead of oil. Drawbacks include high viscosity and thermoplastic tendencies becoming more pronounced at the higher MWs. Also has mechanical properties (surface tension) that cause it to separate from oil. This may become less pronounced at the higher MWs but I have not had a chance to test this at this time.

Applications:

Polyethylene glycol 400 is suited to prepare for the soft capsule most. The polyethylene glycol 400 is a liquid and has a broad compatibility with various solvents, so it is a good solvent and solubilizer and is widely used in liquid preparations, such as the oral solution, eye drops and so on. When the vegetable oil is not suitable for a co-active ingredient carrier material, the polyethylene glycol is the preferred substitute material because the polyethylene glycol is stable and non-perishable. Besides, the injections containing polyethylene glycol are very safe and stable as long as it has been heated to 150 degrees Celsius. In addition, it can blend with PEG with high molecular weight and the mixture has a good solubility and drug compatibility.
