Abstract
The liquid detergent composition is provided with a high detergency and ensuring a good dispersion stability of builder particles and comprises a liquid dispersion containing (a) 30 mass % or more of a specific inorganic builder particle and (b) a block or graft polymer having a carboxyl group (i) and a polymer chain (ii), having, as its structural unit, an alkyleneoxy group, the composition having a viscosity (25° C.) of 3000 mPa·s or less and a volumetric separation rate (25° C., allowed to stand for 30 days) of 5% or less.

A liquid detergent composition comprising a liquid dispersion medium and a solid dispersoid, dispersed in the liquid dispersion medium, the composition having a viscosity (25° C.) of 3000 mPa·s or less and a volumetric separation rate (25° C., allowed to stand for 30 days) of 5% or less, wherein at least part of the solid dispersoid is particles of at least one inorganic builder (a) selected from the group consisting of an aluminosilicate compound, a crystalline silicate compound and a carbonate in an amount of 30 mass % or more per the composition and the liquid dispersion medium and/or the solid dispersoid contains a block or graft polymer (b) having (i) a carboxyl group or a salt thereof and (ii) a polymer chain having the constituting unit of an alkyleneoxy group;
- wherein (b) is a copolymer of an ester of a polyalkylene glycol and a vinyl monomer having a carboxyl group and a vinyl monomer having a carboxyl group or a salt thereof, and
- wherein the ratio of water in the liquid dispersion medium is 5.5 to 20 mass %.
A liquid detergent composition comprising a liquid dispersion medium and a solid dispersoid dispersed in the liquid dispersion medium, the composition having a viscosity (25° C.) of 3000 mPa·s or less and volumetric separation rate (25° C., allowed to stand for 30 days) of 50% or less, wherein at least part of the solid dispersoid is particles of at least one inorganic builder (a) selected from the group consisting of an aluminosilicate compound, a crystalline silicate compound and a carbonate in an amount of 30 mass % or more per the composition, and the liquid dispersion medium and /or the solid dispersoid contains a block or graft polymer (b) having (i) a carboxyl group or a salt thereof and (ii) a polymer chain having the constituting unit of an alkyleneoxy group;
- wherein (b) is a copolymer of a polyalkylene glycol ether having a reactive unsaturated group and a vinyl monomer having a carboxyl group or a salt thereof, and wherein the ratio of water in the liquid dispersion medium is 5.5 to 20 mass %.
