Polyethylene Glycol
Polyethylene glycol (PEG) and polyethylene oxide (PEO) are polymers having an identical structure, and are the most commercially important polyethers. Poly(ethylene glycol) or poly(ethylene oxide) refers to an oligomer or polymer of ethylene oxide. PEG and PEO are liquids or low-melting solids, depending on their molecular weights. Both are prepared by polymerization of ethylene oxide. While PEG and PEO with different molecular weights find use in different applications and have different physical properties (e.g. viscosity) due to chain length effects, their chemical properties are nearly identical. Derivatives of PEG and PEO are in common use, the most common derivative being the methyl ether (methoxypoly(ethylene glycol)), abbreviated mPEG. Poly(ethylene glycol) is non-toxic and is used in a variety of products. It is the basis of a number of laxatives (e.g. macrogol-containing products such as Movicol® and polyethylene glycol 3350, or MiraLax® or GlycoLax). It is the basis of many skin creams, as cetomacrogol, and sexual lubricants, frequently combined with glycerin. Whole bowel irrigation (polyethylene glycol with added electrolytes) is used for bowel preparation before surgery or colonoscopy and drug overdoses Source:
