Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an aqueous detergent composition.

[0002]

2. Description of the Related Art In recent years, there are household equipment, office equipment and toilet equipment in the home, most of which are made of plastic and used for various purposes. Since these devices are close to us, they come into direct contact with hands and skin, become dirty, and require cleaning. For this cleaning, cleaning agents that are commonly used require time and effort for preparation and subsequent emptying, and if the cleaning agent is not removed by wiping twice, it will become sticky during use. There is a feeling and leaves an unpleasant feeling. Further, in some cases, the residual may not be preferable. From these facts, it has been considered that the cleaning agents for these devices are troublesome before and after use. In order to save such troublesome work, a dust removing tool using a cloth containing silicone oil or the like or a fiber containing silicone oil or the like is commercially available. These are simple and excellent for the purpose of removing dust, etc., but are not sufficient in terms of removing stains such as hand marks and sebum adhered to devices.

[0003]

An object of the present invention is to remove stains such as by directly spraying or spraying a detergent composition on the surface of appliances, and then using a paper such as a tissue paper or a toilet paper to clean the appliances. It is a detergent composition that can be removed by wiping the detergent composition remaining on the surface of the product once, has excellent stain removal performance, and does not leave a sticky feeling after use and is easy to use. The purpose of the present invention is to provide a labor-saving cleaning composition that can be used.

[0004]

SUMMARY OF THE INVENTION The present invention comprises (A) an amphoteric surfactant, alkyl betaine 0.2% to 1.0% by weight, (B) ethanol or isopropanol, or 25% by weight of any mixture of both. An aqueous detergent composition comprising 45% by weight and (C) a balance of water, and a toilet seat detergent composition.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Various compounds can be used as the amphoteric activator alkyl betaine used in the present invention, and examples thereof include coconut oil alkyl dimethylamino acetic acid betaine and lauryl dimethyl amino acetic acid betaine. Particularly preferred.

The compounding amount of the amphoteric activator alkyl betaine is
In order to be able to remove it by wiping once, it is desirable to be 1.0% by weight or less, more preferably 0.5% by weight or less.

The monohydric alcohol is composed of ethanol, isopropanol, or a mixture of isopropanol and ethanol, and a mixture of isopropanol at an arbitrary ratio is preferable for indoor use. Further, when using papers such as tissue papers that are familiar in order to wipe them off easily, if the content of the monohydric alcohol is less than 25% by weight, paper scraps are often generated and broken, which is not preferable. On the other hand, when it exceeds 45% by weight, the generation and breakage of paper waste do not occur, but the foamability disappears, the fluidity of the liquid becomes faster, and the usability deteriorates.

Regarding ethanol used as a monohydric alcohol, the amount of ethanol contained in the whole composition is 2
It is particularly important from the viewpoint of stability and feel that no turbidity occurs at a concentration of 5% by weight to 45% by weight. Therefore, the amount of ethanol used in the ethanol solution must be 25% by weight to 45% by weight when ethanol is used alone or as a mixture of ethanol and a denaturant. Furthermore, the use of non-soluble ingredients in the alcohol solution causes turbidity,
The stability may be significantly inferior. Various surfactants, especially nonionic surfactants may be used for stabilizing the solubilization of this composition. However, when these are used, the feel is far from that of the intended composition of the present invention. And is not appropriate to use.

For the purpose of stabilizing the solubilization, one or more selected from octaacetylated sucrose, phenylethyl alcohol, brucine, denatonium benzoate, and geraniol are used for the purpose of using the product of the present invention. It is preferable to use it together with the combination of. Various components are contained in ethanol in a proportion of 0.0012 to 0.3%, and the preferable blending amount thereof is 0.00025 to 0.15% in the detergent composition of the present invention.

Further, to the detergent composition of the present invention, it is possible to add amide propyl betaine, which is a surfactant similar to alkyl betaine, in a quantitative range that does not impair the object of the present invention. Specific examples of such an activator include coconut oil fatty acid amide propyldimethylaminoacetic acid betaine, lauric acid amide propyldimethylaminoacetic acid betaine, coconut oil fatty acid amide propyldimethylhydroxysulfopropylammonium betaine, lauryl hydroxysulfobetaine, 2-alkyl- N-carboxymethyl-N-hydroxyethyl imidazolinium betaine, 2-alkyl-N-carboxyethyl-N-hydrmexethyl imidazolinium betaine, 2-alkyl-
Examples thereof include N-sodium carboxymethyl-N-carboxymethyloxyethyl hydroxyethyl imidazolinium betaine.

In addition, the detergent composition of the present invention may utilize various additives added in the field of the product concerned, as long as the object of the present invention is not impaired. Examples of such substances include various fungicides, antiseptics, antibacterial plant extracts, deodorant plant extracts, colorants, ultraviolet absorbers, and flavoring agents.

The cleaning composition of the present invention is turned upside down in a commonly used container having a perforated upper cap, and liquid is applied to the soiled portion. Alternatively, it is used by placing it in a foamed container with a trigger or a squeeze foamer container, blowing it on the object to be cleaned in a foamed manner, spreading it with tissue paper or toilet paper, and then wiping it off. Further, if it is difficult to wipe the product of the present invention or if it is not desired to apply it to the peripheral portion, it can be sprayed on a dry cloth, tissue paper, or toilet paper, and can be used by wiping off the object to be cleaned while wet with the liquid. .

The contents of the present invention will be described in more detail with reference to the following examples, but the present invention is not limited thereto. The evaluation was made based on the items (1) appearance of liquid, (2) non-stickiness, (3) generation of waste paper, and (4) difficulty in flowing liquid. The specific contents of these are as follows.

(1) Appearance of liquid It was placed in a glass sample bottle and visually judged.
When it was transparent, it was represented by O, and when it was turbid, it was represented by X.

(2) Non-Stickiness The sample was placed on a plastic toilet seat at a rate of 5 ml / 30 cm ² , wiped once with a tissue paper, and then evaluated by sensory evaluation. When there is no stickiness, it is indicated by ○, when it is slightly sticky, it is indicated by △, and when it is sticky, it is indicated by ×.

(3) Generation of waste paper A sample was applied under the same conditions as in the evaluation in (2) above, and the sample solution was spread evenly on toilet paper (Daio Paper Co., Ltd., Eliel) and rubbed to remove dirt. After that, the generation of waste paper was visually determined. When scraps are not observed, it is indicated by O, when scraps are observed, it is indicated by Δ, and when scraps are observed, it is indicated by X.

(4) Difficulty in flow of liquid The flow condition when a sample was discharged by a trigger to a plastic plate inclined at 45 ° was judged based on the product of the present invention. When the product is equivalent to the product of the present invention, it is represented by O, when it is slightly inferior to the product of the present invention, it is represented by Δ, and when it is inferior to the product of the present invention, it is represented by X.

Examples 1 to 8 Ethanol 30 containing 0.3% phenylethyl alcohol
