PURPOSE:To obtain the subject detergent easy to treat the waste water resulting from its use, excellent in handleability and safety, useful for wiring boards, etc., by incorporating a tetraalkylammonium hydroxide as the chief component with water glass. CONSTITUTION:The objective detergent can be obtained by incorporating (A) a tetraalkylammonium hydroxide as the chief component with (B) water glass of composition Na2O.nSiO2 (where, n is >=1.1; namely, the molar ratio Na2O /SiO2 is <=0.9). The amount of the water glass to be used is pref. such as to be >=0.1wt.% in terms of NA2O concentration. |
