Patent ID: 6894016

Claim:
A liquid detergent composition comprising (a) 3 to 15 mass % of water, (b) 0.5 to 50 mass % of a builder composed of a water-soluble inorganic salt of which solubility in distilled water is 0.5 g/15 g (25° C., distilled water) or more, and (c) 20 to 85 mass % of a substance liquid at 25° C. comprising at least one selected from the group consisting of a surfactant (c1) and a water-miscible organic solvent (c2), wherein part of (b) is present in solid state in the composition, and the following formula (1) is satisfied: σ2/σ1≧10 (1) wherein σ1 is the electric conductivity (S/cm, 25° C.) of the liquid detergent composition, and σ2 is the electric conductivity (S/cm, 25° C.) of aqueous solution of which concentration of total water-soluble inorganic salt in the composition including (b) is 3.22 mass %, and wherein the viscosity (20° C.) of the liquid detergent composition is to 10 to 2500 mPa·s.
