PURPOSE:To obtain a low-pollution petroleum-based solvent securing detergency equivalent to that of 1,1,1-trichloroethane and perchloroethylene solvents by mixing well-known chemical substances having strong detergency. CONSTITUTION:This detergent is obtained by mixing a petroleum-based solvent with a bromine-based solvent at a definite ratio, especially at a ratio of 1:(1.5-4) as a detergent for dry cleaning. The detergency of the detergent can freely be controlled from high detergency to soft detergency by changing a mixing ratio of the petroleum-based solvent with the bromine-based solvent. |
