PURPOSE:To obtain the subject remover excellent in the ability to remove oil fouling sticking and remaining on a gray fabric and sewed product by blending an oil-soluble anionic surfactant with oil-soluble nonionic surfactant, amphiphatic substance and solvent. CONSTITUTION:An oil fouling remover obtained by blending an anionic surfactant, expressed by the formula (n is 0-10; R1 is 6-20C alkyl; R2 is 2-4C alkylene oxide residue; M is alkali or alkaline earth metal, alkanolamine, ammonium, etc.), a nonionic surfactant both having extremely strong solvency for oils, especially a surfactant having a narrower molecular weight distribution than that of normal polyoxyakylene alkyl ether type nonionic surfactant and a mixture thereof, an amphiphatic substance (e.g., n-butanol), such as 3-10C alcohol, and a solvent (e.g., petroleum-based hydrocarbon and alkyl halide). The above- mentioned remover has high ability to remove oil fouling from fiber and enables homogeneous dyeing. |
