Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (1) Purpose of the Invention [Field of Industrial Application] The present invention is applicable to walls, tiles, plastics, joints,
The present invention relates to a foaming liquid cleaning composition for removing or cleaning dirt and mold stains adhering to the surface of ceramics, etc.

[Conventional technology]

Changes in the housing environment in recent years have increased the airtightness of the interior of the house, causing the problem of mold stains due to moisture, and there is a demand for liquid cleaning agents that can clean not only dirt but also mold stains at the same time. Therefore, as disclosed in Japanese Patent Application Laid-Open No. 59-93799, hypochlorite, which is a mold stain removal ingredient,
A liquid cleaning agent has been proposed in which an alkaline agent as a stabilizer for the salt is mixed with a surfactant as a dirt substance cleaning component.

[Problem that the invention seeks to solve]

However, the above-mentioned liquid cleaning agents have poor foaming properties and are generally used by spraying, but since hypochlorite is an irritant, it may cause irritating odors when scattered, and e.g. There was a danger that entering the area would cause nausea and even fever. At the same time, due to its low foaming properties, it is difficult to form voluminous foam with little dripping, and dirt cannot be surrounded by foam for a long period of time, so there is the problem that the cleaning power of the cleaning ingredients is not fully demonstrated. Ta.

Therefore, as a result of intensive studies with the aim of solving the above problems, the present inventors added a specific solvent that is stable to liquid cleaning components containing hypochlorite and alkaline agents to these components. It has been found that when added, a foaming liquid detergent composition that can achieve the above object is obtained,
We have arrived at the present invention.

(2) Structure of the invention [Means for solving the problems] The gist of the present invention to achieve the above object is a foaming liquid detergent composition characterized by containing at least the following components: It exists in things.

a) 0.1-8% by weight of hypochlorite.

b) 0.1-10% by weight of alkaline agent.

C) 0.1 to 8% by weight of a surfactant that is substantially stable to hypochlorite and alkaline agents.

d) General formula CH, -○-(E○)n(PO)m-CH.

0.1 to 10% by weight of the solvent represented by the formula (% formula % is -CH=CH, -0-, and PO is 1 to CH.

455, m is 0-5. n+m≧1).

The first component of the composition of the present invention is hypochlorite.

It effectively decomposes and cleans organic matter with its strong oxidizing action, exhibits excellent sterilizing power, and is effective in removing mold stains. As the hypochlorite, particularly sodium hypochlorite and/or potassium hypochlorite are suitable, and the blending amount is as follows:
0.1 to 8% by weight, preferably 0.1 to 5'% by weight. If it is less than 0.1% by weight, the effect will be low and it will be impractical, and if it exceeds 8% by weight, the effect will not be improved and it will be uneconomical. By the way, if it is stored for a relatively long time,
Since they tend to decompose over time and become less effective, they are also uneconomical.

The alkaline agent, which is the second component of the composition of the present invention, is effective in suppressing the decomposition of hypochlorite and promoting its effect. Examples of alkaline agents include alkali metal hydroxides such as sodium hydroxide and potassium hydroxide, sodium carbonate,
Examples include sodium silicate, but considering relatively long-term stability, sodium hydroxide and potassium hydroxide are particularly suitable, and the blending amount is 0.1 to 10% by weight.
Preferably it is 0.1 to 5% by weight. If it is less than 0.1% by weight, the effect is low, and if it exceeds 10% by weight, it tends to accelerate the decomposition of hypochlorite over time.

The surfactant, which is the third component of the composition of the present invention, has the effect of improving the effect of hypochlorite, especially the penetrating power;
In order to maintain the stability of hypochlorite, polyoxyethylene alkylphenyl ether sulfate, alkyldiphenyl ether disulfonate, alkyl sulfate, alkane (di) sulfate, alkyl dimethylamine oxide, fatty acid soap, etc. Particularly preferred, but other conventional
It does not prohibit or exclude the use of those used in liquid cleaning compositions. These can be used alone or in combination, and the blending amount is 0.
It is 1 to 8% by weight, preferably 0.1 to 3% by weight. 0
．． If it is less than 1% by weight, the effect will be low.

If it exceeds 8% by weight, the stability of hypochlorite is impaired and its permeability is reduced.

The solvent represented by the above general formula, which is the fourth component of the composition of the present invention and is the most characteristic component in the composition of the present invention, is extremely effective in imparting foaming properties and improving permeability. At the same time, it also effectively removes oil-based stains. This solvent is alkylene glycol dimethyl ether, and the bonding order of oxyethylene and oxypropylene does not matter. The terminal bonding group is particularly preferably a methyl group; if the length is longer than an ethyl group, the stability with primary sodium hypochlorite will be significantly reduced. Regarding the number of added moles of ethylene oxide and propylene oxide, ethylene oxide is 1 to 455 moles, and propylene oxide is 0.
~5 mol is required. It is technically difficult to manufacture products with an added mole number of ethylene oxide exceeding 455 moles, and products with an added mole number of propylene oxide exceeding 5
If it exceeds this amount, it becomes insoluble, which is not preferable. It is preferable that the number of moles of ethylene oxide added>the number of moles of propylene oxide added, and that the former is 10 and the latter is 1 or more. Particularly preferred solvents include ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, nonaethylene glycol dimethyl ether, etc., and borinitylene glycol dimethyl ether having an added mole of ethylene oxide of 1 to 455 moles is effective.

The blending amount is 0.1 to 10% by weight, preferably 0.1 to 5% by weight. If it is less than 0.1% by weight, it will not be effective, and if it exceeds 10% by weight, the stability of hypochlorite will decrease. becomes extremely worse.

In the composition of the present invention, in addition to the above-mentioned basic ingredients, appropriate amounts of known fragrances, colorants, etc. that are stable against these ingredients, especially hypochlorite and alkaline agents, may be blended. It goes without saying that there is.

Furthermore, a stability test of sodium hypochlorite was conducted against 1 degree of solvent. In this test, the sample was stored at a constant temperature of #J40°C for 7 days, and the residual rate of sodium hypochlorite was calculated by measuring the available chlorine concentration. The results are shown in Table 2.

(Table 2 □%) (3) Effects of the Invention According to the composition of the present invention, a specific solvent is added to a conventionally known liquid detergent composition, and as is clear from the examples, foaming properties are obtained. When sprayed with a foaming spray, it is applied with a particularly voluminous and homogeneous foam. Therefore, it is possible to prevent danger to the human body due to the splashing of hypochlorite-containing liquid, and the foaming of the liquid can surround the stain for a relatively long time, and the addition of the solvent can improve the permeability. By improving this, cleaning power can be fully demonstrated.

In addition, since it is in an excellent foaming state, it can be visually confirmed, and it can be applied accurately to the desired area to remove mold stains, etc., so it has the advantage that it can be used economically. It is extremely useful for practical use as a liquid cleaning agent.
