The use of poly(ethylene) oxide (PEO) as a gelator has been evaluated with a selected list of organic solvents. From the 26 solvents tested, eight formed gel matrices. This number was extended to 19 when poly(ethylene) oxide was used with a mixture of solvents. The procedure for the preparation of PEO organogels is described, and their application for the crystallization of small molecules using different crystallization techniques in the presence of organic solvents is discussed.
