PURPOSE:To provide a liq. detergent compsn. improved in stability after the lapse of time by blending water with a hydrocarbon having a specific b.p., a salt of paraffinsulfonic acid, a water-soluble inorg. salt, and an anionic surfactant and/or an ampholytic surfactant. CONSTITUTION:A salt of paraffinsulfonic acid (B) of the formula: Ps-(M<1>)n [wherein Ps is the residue of a 10-18C alkylsulfonate; M<1> is an alkali metal ion or an alkaline earth metal ion; and n is 1 or 1/2], a water-soluble inorg. salt (c) such as NaCl, and an anionic surfactant and/or an ampholytic surfactant (D) are dissolved in water to prepare a soln., which is then admixed with a hydrocarbon (A) having a b.p. of 0 to 40 deg.C under ordinary pressure, such as 2-methylbutane, to obtain a liq. detergent compsn. excellent in stability after the lapse of time and having an (A) content of 2 to 12wt.%, a (B)/(A)wt. ratio of 1/0.6 to 1/5, a proportion of (C) to (B) of 1 to 50wt.%, and a (B)+(C) content of at most 30wt.%. The liq. detergent compsn. is stored under pressure in a pressure container. |
