題があった。However, currently commercially available liquid detergents have a composition in which components are uniformly dissolved due to the requirement of storage stability, and water-insoluble zeolites used for improving detergency in granular detergents are used. There was a problem that it could not be blended.

ーの配合量を増加させている。For this reason, various attempts have been made to improve the detergency, and attempts have been made to use soluble calcium trapping builders such as sodium citrate and polycarboxylate (Japanese Patent Application Laid-Open No.
Nos. 56-127696 and 60-106892). In Japanese Patent Application Laid-Open No. 58-145794, a large amount of an electrolyte is blended, and a surfactant is salted out to form a suspension having a coarse three-dimensional structure, thereby increasing the blending amount of the builder.
しかし、上記の方法によっても、洗浄力の改善には限
界があり、液体洗浄剤は、粒状洗浄剤と比べて原料費が
高いにもかかわらず、洗浄力の点でやや劣っていた。However, even with the above method, there is a limit to the improvement of the cleaning power, and the liquid cleaning liquid is somewhat inferior in terms of the cleaning power, though the raw material cost is higher than that of the granular cleaning liquid.

ため、ゼオライトが凝集して分散安定性が改善されな
い。The present inventors have conducted various studies on various polymer substances, and found that the polymer substance which is uniformly dissolved in the concentrated surfactant aqueous solution system as described above and has a thickening effect exerts a dispersion stabilizing effect of zeolite. I found something. For example, polyethylene glycol satisfies the above condition (solubility), but does not satisfy the condition (thickening effect), so that zeolite cannot be stably dispersed. On the other hand, polyvinyl alcohol and polyacrylic acid satisfy the opposite condition, but do not satisfy the condition, so that the zeolite aggregates and the dispersion stability is not improved.

0重量％、好ましくは0.5〜５重量％配合することが必要
である。この配合量が0.3重量％未満では分散安定性が

ない。The polymer substance of the present invention is contained in the liquid detergent composition in an amount of 0.3 to 1%.
It is necessary to add 0% by weight, preferably 0.5 to 5% by weight. If the amount is less than 0.3% by weight, the dispersion stability will not be good, while if it exceeds 10% by weight, the effect will not be improved.

る。Possibly, a part of the polymer substance is adsorbed on the zeolite surface to exert a protective colloid effect, which contributes to the improvement of dispersion stability. Therefore, when the amount of the polymer substance added is small, the protective colloid effect is not exhibited, and it is considered that the dispersion stability is not sufficiently improved.
