ABSTRACT:
This application discloses a composition and method for gelling volatile liquids and the gelled volatile liquid. The composition comprises a cellulose ester coated with up to about 50% paraffin. When the paraffin coated particles of the cellulose ester are used to gel a volatile liquid, the gelled structure has a slower evaporation rate than the volatile liquid alone. The process of this invention includes the steps of adding melted paraffin to a cellulose ester, cooling, and stirring until free flowing granules are formed. When the granules are added to an organic solvent, the solvent gels and has a very slow rate of evaporation.
