PURPOSE:To provide the title detergent for degreasing use, high in the stability to metals, free from any ingredients leading to environmental pollution, having degreasing power and penetrability comparable to those of chlorine-based solvents. CONSTITUTION:The objective water base detergent characterized by containing, besides water, (A) 0-20wt.% of sodium carbonate, (B) <=20wt.% of sodium silicate, (C) <=20wt.% of sodium gluconate, (D) 10-60wt.% of a polyoxyethylenepolyoxypropylene block copolymer obtained by adding ethylene oxide to polypropylene glycol 1000-2000 in molecular weight, (E) 5-30wt.% of at least one kind of nonionic surfactant, ethylene oxide/propylene oxide adduct of 10-14C straight chain secondary alcohol, and (F) 10-50wt.% of at least one kind of nonionic surfactant, ethylene oxide/propylene oxide adduct of 10-14C straight chain secondary alcohol. |
