Solvent Solvent A solvent (from the Latin "solvō", "loosen, untie, solve") is a substance that dissolves a solute (a chemically distinct liquid, solid or gas), resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Common uses for organic solvents are in dry cleaning (e.g. tetrachloroethylene), as paint thinners (e.g. toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers (e.g. hexane, petrol ether), in detergents

Although this method is quick, it can have the undesirable side effect of tearing the paper when the folded tabs pull through. Tearing usually does not occur when higher quality paper is used or the staple connects three or more sheets. The inventor of the original staple remover,
