Polyethylene Glycol 400 Peg400 for Steroids Conversion
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.
