Problems solved by technology

However, since most compositions have a high viscosity of 1000 mPa·s or more, there is a problem of droplets in addition, and relatively low-viscosity compositions are poor in long-term storage stability
JP-A 5-501574, the Japanese translation of PCT Laid-open, equivalent to WO91 / 08280, discloses a surfactant composed of a deflocculating polymer containing a special structure suspended in an aqueous continuous phase A liquid detergent composition of flaky droplets, and the viscosity range of the composition is 30-1750mPa·s, but because the water continuous phase of the composition does not contain inorganic salt builders such as alkaline reagents higher than solubility, So its cleaning power is poor

Embodiment Embodiment 1-8 and comparative Embodiment 1-3

[0086] The liquid detergent compositions given in Table 1 were prepared by the following method, and the obtained compositions and the conductivity, easiness of use (viscosity, spinnability) in the component (b) used in the preparation of each composition were evaluated. ), normal cleaning power and applied cleaning power. Table 1 presents the results. [Preparation of Liquid Detergent Composition]

[0087] Various liquid detergent compositions shown in Table 1 were prepared by weighing and mixing the mixing ingredients in proportions for 100 grams of the liquid detergent composition. The specific operation method is as follows.

[0088] (1) Preparation of Examples 1-8

[0089] All ingredients (c) in specified amount were weighed and placed in a 100 ml beaker and mixed at room temperature. Specified amounts of polymeric dispersant (lyophilized product) and fluorescent bleaching agent were added, and heated at 50° C. for 5 hours. The mixture was gradually cooled to normal t...

Abstract

The invention relates to a liquid detergent of a high cleaning power and an excellent storage stability while maintaining the ease of use. A liquid detergent composition comprising, at a specific ratio individually, (a) water, (b) a builder composed of a water-soluble inorganic salt of which solubility in distilled water is 0.5 g / 15 g (25 DEG C, distilled water) or more, and (c) a substance liquid at 25 DEG C containing at least one selected from the group consisting of surfactant (c1) and water-miscible organic solvent (c2) in which part of (b) is present in solid state in the composition, and its electric conductivity measured by a specific method is within a specified range.

Description

technical field [0001] The present invention relates to a liquid detergent composition having low viscosity and low spinnability, easy to use and excellent detergency. Background technique [0002] Liquid detergents are easier to use than powdered detergents because they dissolve completely and can be applied directly to the soil. Liquid detergents are often dissolved in wash water if not applied directly to the soil. In this case, the cleaning power of the liquid detergent tends to be smaller than that of the powder detergent. This is because some problems occur in the stability of the system when a booster ingredient such as an alkali agent or a Ca scavenger is sufficiently blended into a composition as a powdery detergent. From this point of view, liquid detergent blended builders have been developed. Japanese Patent Application Laid-open No. 58-145794 discloses aqueous flowable detergent compositions containing an effective amount of detergent builder which can be add...
