Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an abrasive-containing liquid cleaning composition, and more particularly, an abrasive-containing liquid cleaning composition having excellent cleaning and polishing power and improved dispersion stability. Regarding the composition
It is something that

Conventionally, liquid detergents for kitchens such as vegetable and dishwashing have been mainly composed of compositions that fully utilize the cleaning power of surfactants.

However, this cleaning agent can be used for cleaning vegetables, liquid oil, etc.
Although it is said to have cleaning power against stains such as semi-solid oils, it has the disadvantage that its cleaning power against stains such as those caused by cooking food, crumbling or dry solidified food, solid oils, and baking oil is relatively weak. Therefore, recently, many liquid cleaning agents containing water-insoluble solid particles such as polishing materials have been proposed.

However, these liquid alkaline cleaners are preferable because they have both normal cleaning power for removing non-adhesive dirt and abrasive power for removing adherent dirt, but they do not remove the liquid during storage. There is a drawback that the water-insoluble solids contained in the liquid: I″V particles precipitate.

For this reason, many attempts have been made to stably suspend these water-insoluble solid particles in a surfactant solution. JP-A-54-1175O6, or a method of stabilizing enzymes using clay minerals (JP-A-56-1989)
-159297 Publication φ) has been proposed. However, these methods are not necessarily fully satisfactory as means for stably suspending water-insoluble solid particles.

In view of these circumstances, the inventors of the present invention have conducted intensive research to preserve the powder cleaning agent containing water-insoluble solid particles in a state with extremely good dispersion stability. Content! A liquid cleaning composition that uses silica stone within a specified range and contains silica stone and a surfactant in a predetermined ratio has excellent cleaning power and polishing power, and also has good cleaning power. The present invention was completed based on this finding.

The present invention provides (A) at least one surfactant 1 to 50% by weight, and (B) A4203 containing 0.2% by weight.
The present invention provides an abrasive-containing liquid cleaning composition characterized in that it contains less than 1 to 50% by weight of an abrasive consisting of silica stone.

In the cleaning composition of the present invention, the surfactant used as the broad component may be an anionic surfactant, a nonionic surfactant, a cationic surfactant, an amphoteric surfactant, or a zwitterionic surfactant. As the anionic surfactant, ordinary sulfonate-based, sulfate-based, and phosphate-based anionic surfactants are used. Among these anionic surfactants, Surpone +- type 7
As the ionic surfactant, for example, straight chain or branched alkyl (08-C2)bententhur'l diphosphate kA
, long chain alkyl (08-C22) sulfonate, chain olefin (cB-C22) sulfonate, etc.
It will be done. Examples of excellent sulfate-based anionic surfactants include long-chain monoargyl (08-C22) sulfate salts, polyoxyethylene (1-G mol) long-chain alkyl (C8-C22) ether sulfate salts, polyoxyethylene (1 to 6 mol) alkyl (08 to 018) phenyl ether sulfate salts, and examples of phosphate anionic surfactants include long-chain monoalkyl, dialkyl or sesqui (for each alkyl group) Examples include phosphates with a carbon number of 8 to 22, polyoxyethylene (1 to 6 mol) monoalkyl, dialkyl or sesquiphosphates (each alkyl group has 8 to 22 carbon atoms), etc. . Cations as counterions for these anionic surfactants include, for example, alkali or alkaline earth metal ions such as sodium, potassium, and magnesium, alkanolamine ions such as monoethanolamine, jetanolamine, and triethanolamine. be.

Examples of nonionic surfactants include polyoxyethylene (1 to 20 moles) long chain alkyl (primary or secondary 08 to C22) ether, polyoxyethylene (1 to 2 moles),
0 mol) argyl (08-018) phenyl ether,
21-xoalkylene compound such as polyoxyethylene polyoxy/propylene block copolymer, higher fatty acid alkanolamide or its alkylene oxide compound, long-chain tertiary amine oxide (012-14)
There are too many to mention.

Examples of the cationic surfactant include quaternary ammonium salts such as long-chain algyltrimethylammonium salts, long-chain alkyldimethylbenzylammonium salts, and long-chain alkylpyridinium salts.

Examples of amphoteric surfactants include dimethyl long chain (cB~
Cl8) alkyl-carboxylammonium betaine, di-long chain (Os-Cl8) alkylaminoalkylene carboxylate, 2-argyl-1-carboxymethyl-1-hydroxyethylimidazolinium betaine, and the like.

These surfactants may be used alone or
Two or more types may be used in combination, and the blending amount is 1 to 50% by weight based on the weight of the cleaning composition, preferably [0-
It is in the range of 300% by weight.

If the weight ratio is outside the range of 1 to 50, the suspension stability deteriorates [7] and is not suitable.

In the cleaning composition of the present invention, the silica stone used as the polishing powder of component (B) contains less than 71 hl+ of At203, a trace component, of 0.2% by weight. A composition using silica stone containing 0.2% by weight or more of At203 as an abrasive has poor dispersion stability and is therefore undesirable.

The blending amount of this silica stone is 1 to 5 based on the weight of the cleaning composition.
It is in the range of 0 weight ratio, preferably 5 to 20 weight ratio. If the blending amount is less than 1% by weight, sufficient ω[gamma] force will be exerted, but if the -force exceeds 50 weight %, the dispersion stability will deteriorate.

The average particle size of Keiken 1 is 1~1,'5
A substance in the range of 0 ru is preferable, and a substance in the range of 5 to 40 U is more preferably used.

If necessary, other optional components can be added to the cleaning composition of the present invention within a range that does not impair dispersion stability. For example, as other optional ingredients, clay minerals such as clays mainly composed of montmorillonite, nontronite, zabonite, hectorite, vermiculite, attapulgite, sepiolyte 1 to 1- and mixtures thereof, calhocite methyl cellulose, methyl cellulose, Addition of water-soluble polymeric substances such as hydroquinoethylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid and its salts, maleic anhydride and its salts is preferred because it further improves the dispersion stability of the composition. These may be used alone or in combination of two or more, and the blending amount is preferably 0.1 to 10% by weight, particularly preferably 0.3 to 10% by weight, based on the weight of the composition. ~5
It is within the weight range.

lower aliphatic alcohols such as ethyl alcohol, and salts such as toluenesulfonic acid and ginlenesulfonic acid.
- Addition of solubilizers such as lithium salts or potassium salts and urea is also preferred since it further improves the dispersion stability of the composition. The amount of these solubilizers to be blended is based on the weight of the composition, and is based on the weight of the composition.
~6 weight range.

Furthermore, enzymes, numbers, dyes, side-by-side agents, anti-scatter agents, etc. can also be added.

The polishing (2-containing liquid cleaning composition of the present invention) does not cause the silica contained therein to precipitate or form a transparent layer even when stored for a long period of time, and has extremely practical value. It's expensive.

Next, the present invention will be explained in more detail with reference to Examples.
