Solutions of cellulose or cellulose ethers in solvent containing triethylheptylammonium chloride, triethyloctylammonium chloride, triethylhexylammonium acetate, triethylheptylammonium acetate, triethyloctylammonium acetate, triethylnonylammonium acetate and/or triethyldecylammonium acetate are provided. The solvent may further include up to 70 wt % of at least one organic solvent, with acetone being the preferred organic solvent. The solution can be formed into a paste for removing paint from wood or metal surfaces. The cellulose (ether) solution can also serve as a reaction medium in which the cellulose and/or the cellulose ether are chemically modified. Finally, the cellulose (ether) solution can be processed into cellulosic shaped articles.
