Features
PEG is soluble in water, methanol, ethanol, acetonitrile, benzene, and dichloromethane, and is insoluble in diethyl ether and hexane. It is coupled to hydrophobic molecules to produce non-ionic surfactants. PEGs potentially contain toxic impurities, such as ethylene oxide and 1,4-dioxane. Ethylene glycol and its ethers are nephrotoxic if applied to damaged skin.

Description
Polyethylene glycol (PEG) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE).
1.PEG is the basis of many skin creams (as cetomacrogol) and personal lubricants (frequently combined with glycerin).
2.PEG is used in a number of toothpastes as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste.
3.In low-molecular-weight formulations (e.g. PEG 400), it is used in Hewlett-Packard designjet printers as an ink solvent and lubricant for the print heads.
4.PEG is used to extend the size and durability of very large soap bubbles.
5.PEG is the main ingredient in many personal lubricants.
