Polyethylene glycol is used in electron microscopy. It is used as a solvent, a dye carrier in inks and a dispersant in water based coatings. Its derivatives like PEG esters are used as surfactants. In the textile industry, it is used as a lubricant, softener, dye carrier dispersant and an anti-static agent. It finds application in personal care products like skin creams, lotions and bath gels.
A mixture of PEG200 with dichloromethane has been recommended as a solvent system for the Sandmeyer conversion of aromatic amines to halides, giving particularly good results for aryl chlorides: J. Chem. Soc., Chem. Commun., 1523 (1984).
For use of polyethylene glycols as phase-transfer catalysts, see Polyethylene glycol 400, B21992.
