Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a liquid cleaning composition containing an abrasive, and more specifically, a liquid cleaning composition containing an abrasive, more specifically, a stable composition that can maintain appropriate fluidity without causing separation of components even after long-term storage. The invention relates to a liquid cleaning composition containing an abrasive.

BACKGROUND ART In recent years, various liquid detergent compositions containing abrasives having excellent cleaning performance such as polishing power and detergency have been proposed as liquid detergents for kitchen use such as for washing vegetables and dishes, or detergents for household use. Conventionally, liquid cleanser compositions have been widely used as typical examples of such abrasive-containing liquid cleaning compositions. This product is made by dispersing abrasive particles in a liquid phase containing a surfactant, etc., and although it has a certain degree of cleaning performance such as emulsifying and dispersing power against dirt and polishing power, the dispersion stability is poor and it cannot be stored. The disadvantage was that the abrasive material settled during the process.

In order to prevent such sedimentation of abrasives in liquid cleaning compositions, various methods have been used, such as a method of incorporating a phosphate (JP-A-47-22906, JP-A-48-84109).
) Method of using surfactant and solubilizer together
-36646, Japanese Patent Publication No. 50-36847) A method using a water-soluble polymer substance (Japanese Patent Publication No. 53-46303, Japanese Patent Application Publication No. 54-74810), a method using an inorganic thickener (Japanese Patent Publication No. 50-50410, 11480 (1972), etc. have been proposed. However, those containing the above-mentioned phosphates cause eutrophication of water, and those containing surfactants and solubilizers lack detergency and foaming power, and also contain water-soluble polymer substances. The thickeners used and those using inorganic thickeners have poor workability because the thickener cannot be easily dispersed in water, and the viscosity changes when stored for a long period of time. These methods are not necessarily satisfactory, as there are concerns about deterioration caused by microorganisms and the like.

In view of these circumstances, the present inventors have conducted extensive research in order to obtain an abrasive-containing liquid cleaning composition that is easy to use and has a suitable viscosity and good dispersion stability without using any phosphates. As a result of repeated research, it was discovered that the objective could be achieved by using a combination of a specific surfactant and a thickener, combined with a specific amount of a specific solubilizer. The present invention was completed based on this knowledge.

That is, the present invention (3 to 40% by weight of a surfactant component consisting of an N anionic surfactant and a nonionic surfactant)
, (0.1 to 10% by weight of at least one thickener selected from Bl water-soluble polymer substances and clay minerals, (C)
Contains 3 to 60% by weight of a water-insoluble abrasive and (D) 0.1 to 5% by weight of at least one solubilizing agent selected from p-paratrunile sulfonate, xylene sulfonate, and benzoate. The present invention provides an abrasive-containing liquid cleaning composition characterized by the following.

In the present invention, among the surfactants used as the N component, sulfonate-based sulfate-based anionic surfactants are used. Among these anionic surfactants, sulfonate-based anionic surfactants include , for example straight-chain or branched alkyl (Cal~c2.
) benzene sulfonic acid [,1m alkyl (C6-C, □
) sulfonates, long chain olefins (08-C2 sulfonates, etc.). Examples of sulfate-based anionic surfactants include long-chain monoalkyl (C, -C2) sulfonates, etc.
22) Sulfate ester salt, polyoxyethylene (1 to 6 mol) long chain alkyl (cm to C2□) ether sulfate ester salt, polyoxyethylene (1 to 6 mol) alkyl (C
, ~C+s) phenyl ether sulfate ester salt, and the like. Cations as counter ions for these anionic surfactants include, for example, sodium, potassium,
These include alkali metal or alkaline earth metal ions such as magnesium, or alkanolamine ions such as monoethanolamine, jetanolamine, and triethanolamine.

Examples of nonionic surfactants include polyoxyethylene (1 to 20 mol) long chain alkyl (equal or secondary C6 to C22) ether, polyoxyethylene (1 to 2 moles),
0 mol) alkyl (C6~C+a) phenylene ether, oxyalkylene adduct compounds such as polyoxyethylenebilioxypropylene block copolymer, higher fatty acid alkanolamide or its alkylene oxide adduct, long chain tertiary amine oxide (C82~ C14)
Examples include.

These surfactants are used in combination of one or more anionic surfactants and one or more nonionic surfactants, and the blending amount is 3 to 40% by weight based on the total amount of the composition.
, preferably in the range of 5 to 30% by weight. This amount is 3
If it is less than 40% by weight, the surface of the item to be washed will have poor finish and water drainage, while if it exceeds 40ii%, a large amount of surfactant will remain on the surface of the item to be washed, resulting in an unpleasant feeling, and it will take a long time to rinse. This is undesirable because of this.

In the composition of the present invention, the thickener used as the BJ acid component is selected from water-soluble polymer substances and clay minerals. Examples of water-soluble polymer substances include calxoxycellulose, polyacrylic Examples of clay minerals include acids and their salts, polyvinyl alcohol, hydroxyethyl cellulose, polyvinylpyrrolidone, maleic anhydride polymers and their salts, and clay minerals such as montmorillonite, nontronite, hectorite, vermiculite,
Clays mainly composed of athanozorgite, sepiolite, and mixtures thereof can be used. Each of these thickeners may be used alone or in combination of two or more, and the amount thereof is 0.1 to 10% by weight, preferably 0.5 to 10% by weight based on the total amount of the composition. It is in the range of 3% by weight. If this amount is less than 0.1% by weight, the viscosity necessary for stabilization cannot be obtained, and if it exceeds 10% by weight, the viscosity becomes too high, which is not preferred for use.

Next, in the present invention, the water-insoluble abrasive used as the CI acid component is preferably one having an average particle size of 1 to iso and a Mohs' hardness of 2 or more. If the number is too small, it does not provide sufficient abrasiveness, and if it exceeds 8, there is a greater tendency to damage the items to be washed, so it is unsuitable.

Examples of suitable abrasive materials include agate, calcite, quartz, silica, alumina, diatomaceous earth, )zolite, feldspar, and
It can trace minosilicate, calcium phosphate, calcium carbonate, dolomite, aluminum oxide, etc.
These may be used alone or in combination of two or more. Abrasives with an average particle size of less than 11 ErL have good dispersion stability but extremely low polishing power, and those with an average particle size of more than 150 - are used for stainless steel, aluminum, glass, and other equipment. It is undesirable because it easily damages the detergent, and furthermore, it settles in the detergent and impairs the dispersion stability.

The amount of abrasive is 3 to 60% by weight based on the total amount of the composition.
The range is good. If this amount is less than 3% by weight, the polishing power is insufficient, and if it exceeds 60% by weight, a desired viscosity cannot be obtained.

Further, the solubilizing agent used as the FD+ component in the composition of the present invention is selected from para-toluene sulfonate, xylene 7''lα salt and benzoate. [Each of these may be used alone or in combination of 28 or more] These solubilizers must be contained as effective ash in a range of 0.1 to 5% by weight based on the total weight of the bottom hardware.

In addition to the above-mentioned essential components, the composition of the present invention may optionally contain other optional components, such as polycarzenic acid, polycarzenic acid, or salts thereof, polyhydric alcohol, and preservatives, to the extent that performance is not impaired. , alkaline agents, inorganic salts, fragrances, pigments, etc.

A liquid cleaning composition containing the abrasive of the present invention has excellent storage stability and does not change in appearance even if left for a long period of time.
