<p>A method for gelifying a carbon-based solvent composition is described. The gel-type cleaning composition includes one or more carbon-based solvents, one or more gelling agents and one or more polar solvents, as well as, optionally, a miscibility-promoting agent. The gelling agent is a finely divided silicon dioxide and the polar solvent is ethanol. The composition preferably includes petrol C, petrol E and petrol F. The method for producing such a gel includes the following steps: a) at least one carbon-based solvent and one gelling agent are mixed to produce a paste, b) a polar solvent is added to the paste to provide a gel and c) at least one carbon-based solvent is optionally added to the gel thus obtained. Application as a cleaning composition, particularly for chewing gum and graffitis.</p> |
