Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an abrasive-containing liquid detergent composition, more specifically, a liquid detergent composition containing an abrasive, which has excellent detergency and abrasive power, is particularly mild to hand skin, and has excellent dispersion stability. The present invention relates to a liquid cleaning composition containing an abrasive.

Conventionally, liquid cleaning agents for kitchens such as vegetable and dishwashing have been mainly composed of compositions that utilize only the cleaning power of surfactants. This type of cleaning agent has excellent cleaning power for cleaning vegetables and stains such as liquid oil, semi-solid oil, etc., but it is also effective for cleaning food that has been burnt or dried and solidified due to food cooking, solid oil, baking oil, etc. The cleaning power is relatively weak, and these are exploited/
For cleaning tableware and cooking utensils, granular, powdered, or liquid polishing cleansers are usually used as cleaning aids.

On the other hand, various liquid cleaning compositions containing water-insoluble abrasives have recently been proposed. These cleaning agents have a combination of normal cleaning power for removing non-stick stains and abrasive power for removing sticky stains. Increasing the content of abrasive to improve its strength not only increases the tendency to damage the items being washed, but also has the disadvantage that the abrasive powder contained therein settles out during storage; If the formulation emphasizes dispersion stability in order to improve these drawbacks, foaming properties and detergency will inevitably deteriorate. For this purpose, the abrasive force,
Cleaning properties such as detergency and foaming properties! There has been a demand for the development of a detergent composition containing an abrasive material with excellent I, and maintaining stability over a long period of time.

As a result of extensive research in order to meet these demands, the present inventors have found that a combination of alkyl ether sulfate, tertiary amine oginide, and water-insoluble abrasive powder is combined with a specific clay and a small amount of alkylbenzene. Based on this knowledge, we discovered that products containing sulfonate have excellent cleaning and abrasive power, are particularly gentle on hand skin, and also have excellent dispersion stability for thick materials. Based on this, the present invention has been completed.

That is, the present invention is based on (A) general formula % formula % (1) (in the formula, R1 is a linear or branched alkyl group having 9 to 15 carbon atoms, n is an integer of 3 to 7, and M is an alkali group). Alkyl ether sulfur 1.5-40 represented by metal, ammonium group or alkanol-substituted ammonium residue)

The present invention provides an abrasive-containing liquid detergent composition characterized in that the weight ratio of component ()/component (e) is 1 or more.

The alkyl ether sulfate used as component (A) in the composition of the present invention is a compound represented by the above general formula (1), in which R3 is a linear or branched alkyl having 9 to 15 carbon atoms. It is the basis. If the number of carbon atoms is less than 9, the cleaning performance will be low, and if it exceeds 15, not only will the rinsing performance be markedly reduced, but the abrasive material in the composition will tend to settle and the stability over time will be impaired, so it is preferable. do not have. Preferred carbon numbers range from IJ to 14. In addition, the number n of moles of ethylene oxide added in general formula (1) is 3 on average.
It is necessary that the number is within the range of 7 to 7; if it is less than 3, the detergency will be reduced, while if it exceeds 7, the foaming power will be low -F. Furthermore, A in general formula (1) is an alkali metal such as potassium or sodium, an ammonium residue, or an alkanol-substituted ammonium residue such as a monoethanol-substituted ammonium residue or a jetanol-substituted ammonium residue.

The content of the component (A) in the composition of the present invention is 5 to 5.
If the content is less than 5% by weight, the detergency will be insufficient, and if it exceeds 40% by weight, the stability of the composition will deteriorate. Good content is 10-2
It is in the range of 0% by weight.

The tertiary amine oxide used as component (B) in the composition of the present invention is a tertiary amine oxide of a mono-long chain argyloodi short-chain alkylamine represented by the general formula (I+), in which R2 is a straight chain or branched alkyl group having 12 to 14 carbon atoms.

When the number of carbon atoms is less than 12, the detergency of the composition decreases, and when it exceeds 14, the stability of the composition is impaired. Further, R3 and R4 in the general formula (1) are a methyl group or an ethyl group, and these may be the same or different.

This tertiary amine oxide has zero
．． It is necessary to contain it in a proportion of 5 to 7% by weight,
If the content deviates from the above range, the detergency in combination with component (A) will decrease.

The water-insoluble abrasive used as component (C) in the composition of the present invention has an average particle size of 1 to 150 μm and a Mohs hardness of 2 to 150 μm.
8. Those with a Mohs hardness of less than 2 + d have a small abrasive force and do not provide sufficient abrasiveness, while those with a Mohs hardness of less than 8 are unsuitable because they have a strong tendency to damage the items to be washed. Examples of suitable abrasives and ()C are agate,
Calcite, quartz, glue, alumina, cinnabar earth, pearlite, feldspar, aluminocitrate, calcium phosphate,
Examples include carbonate cal/rum. These may be used alone or in combination of two or more. This ω [The particle size of the raw material is less than 1μ (d) Good for dispersion stability, but the abrasive power is extremely low, and if the size is too large, it will easily damage stainless steel, aluminum plates, glass, and other materials It is undesirable because it easily sediments in the detergent composition, impairing the dispersion stability, and having an adverse effect on the skin.

If the composition contains 30% by weight or more of particles with a particle size of %vc of 200μ or more, it cannot be used due to poor stability.3 The content of the water-insoluble Lab II 4N in the composition of the present invention is 2 to 30% by weight. , and this content is within the range of 2
If it is less than 30% by weight, the polishing power is insufficient, and if it is less than 30% by weight.
If it exceeds 20%, the cleaning power will be relatively low and the stability will also be reduced, making it undesirable as a cleaning agent. The favorable content is 5~
It is in the range of 15% by weight.

In addition, the clay used as component (D) in the composition of the present invention is mainly composed of smectite and/or double-chain clay minerals, such as montmorillonite and nontronite. , hectorite, vermiculite, attapulgite, sepiolite and mixtures thereof. These clays have a 0.1-1
It is necessary to contain 0% leaf. These have thixotropic properties and are highly desirable for stabilizing the composition over time. If this content is less than 0.1% by weight,
The anti-sedimentation ability of the polishing material when left standing is weak, and the thixotropy imparting effect is insufficient.If it exceeds 10% by weight, the desired viscosity reduction cannot be obtained when the composition is used, resulting in poor usability. This is not desirable as it will make things worse. A particularly desirable content is in the range of 0.3 to 2% by weight.

Directional I1 used as component (K) in the composition of the present invention
The m-alkylbenzene sulfonate has an average carbon number of 8 to 1.
At least one salt selected from salts of alkali metals such as sodium and potassium, alkaline earth metals such as magnesium, ammonium, and alkanol-substituted ammonium salts having a straight chain alkyl group of 4; If the number of carbon atoms is outside the above range, the cleaning performance will be poor, and no excellent synergistic effect can be obtained in combination with other components.

The content of the above-mentioned component in the composition of the present invention is 0.5
-7% by weight, if this amount is less than 0.5% by weight, the suspension stability will be poor, and if it still exceeds 7% by weight, the detergency will be poor and the mildness to the skin of the hands will be poor. I can't get it.

Furthermore, in the composition of the present invention, it is important that the (B) component and (E) component are used together in such a ratio that the weight ratio of the (B) component/(E) component is 1 or more. When used in combination in this ratio, a remarkable synergistic effect can be obtained in terms of both detergency and foaming power, and it is gentle on the skin of the hands. If the ratio is less than 1, such effects cannot be obtained.

The composition of the present invention is formulated into a liquid using water as a medium, and adjusted to have a viscosity suitable for use, for example, 10 to 8 pores at room temperature. Moreover, other components used in ordinary liquid cleaning compositions can also be blended, if desired.

The liquid detergent composition of the present invention is extremely easy to use, is easy to use, eliminates the drawbacks of conventional detergents, and has excellent foaming properties, cleaning power, abrasive power, and dispersion stability. It is a highly practical abrasive cleaner that is mild on sensitive skin.

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