Patent ID: 8071521

Claim:
A liquid detergent composition comprising: (a) 4 to 50% by mass of a mixture comprising compounds represented by formula (1) having average addition mole numbers m and n of propylene oxide and ethylene oxide satisfying 0.15â‰¦mâ‰¦0.8 and 1â‰¦nâ‰¦2.3, respectively; (b) 1 to 30% by mass of an amine oxide surfactant having a hydrocarbon group having 8 to 18 carbon atoms and an alkyl group having 1 to 3 carbon atoms or a hydroxyalkyl group having 1 to 3 carbon atoms; a phase stabilizer selected from the group consisting of hydrotrope agents and organic solvents; and water; wherein a mass ratio of (a)/(b) is 10/1 to 2/1: R 1a Oâ€”(PO) m1 (EO) n1 SO 3 Mâ€ƒâ€ƒ(1) wherein, R 1a represents a linear alkyl group having 8 to 18 carbon atoms, in which a carbon atom bound to an oxygen atom is primary; PO and EO represent a propyleneoxy group and an ethyleneoxy group, respectively; m1 and n1 represent addition mole numbers of PO and EO, respectively, which are integers of not less than 0; and M represents a cation.
