Description

Detailed Description of the Invention

[0001]

[Industrial application] By filling the liquid level of the liquid in a transparent container and suppressing the photodegradation of hypochlorite, the usage amount can be easily grasped and a stable function can be obtained. The cleaning agent that can be exerted.

[0002]

BACKGROUND OF THE INVENTION Detergent compositions containing hypochlorite are bleached, sterilized, deodorized,
It has a high effect on mold removal, slime removal, toilet, pipe cleaning, etc. However, since hypochlorite is easily photodecomposed and its concentration is lowered, it is necessary to fill the light-shielding container containing titanium oxide, carbon, or the like. In such a light-shielding container, since visible light is blocked, the liquid level cannot be seen and it is difficult to grasp the usage amount.
Therefore, when diluting for bleaching or the like, it is general to measure using a cap. With this method, there is the inconvenience that it takes time to clean the cap each time it is used, and if the cap is closed without cleaning, the content liquid remaining in the cap drips, causing the inconvenience of discoloring clothes or furniture. . In addition, it is necessary to use a laminated plastic container when a part of the container is made transparent so that the usage amount can be grasped. It has the drawback that it cannot be molded with a molding machine for multi-layer plastic containers.

In view of the above situation, the object of the present invention is to make the amount of use simple by filling a container in which the liquid surface of the content liquid can be seen through and has an effect of suppressing the photolysis of hypochlorite. It is to provide a cleaning agent that can be grasped and that can stably function.

[0004]

In view of such circumstances, the inventors of the present invention have earnestly studied and, as a result, did not block all visible light, but decided to use light having a wavelength of 400 to 500 nm in visible light. It was found that photodecomposition of hypochlorite is suppressed by reducing the light transmittance in the ultraviolet region, and the present invention has been completed.

That is, the cleaning agent of the present invention is filled in a container in which the liquid level of the content liquid can be seen through and is 400 to 500 nm.
By providing a cleaning agent that reduces the transmittance of light in the wavelength range and light in the ultraviolet region and suppresses the photolysis of hypochlorite, the usage amount can be easily grasped and the function can be stably exhibited. It is a thing.

400 incorporated into the detergent container of the present invention
Inorganic pigments such as anthraquinone-based red / yellow, polyazo-based yellow, benzimidazolone-based yellow / orange, quinacridone-based red / magenta, phthalocyanine-based pigments, azo-based pigments, etc. Examples of the pigment include chrome yellow and the like, and one kind or a mixture of two or more kinds is used, but it is not limited to these and is 400 to 500.
Any material can be used as long as it has an effect of reducing the light transmittance of nm and can see through the liquid surface of the content liquid. Purple, green yellow, blue,
Various color tones such as yellow, green-blue, orange, blue-green, and red are conceivable, but they are compounded so that the light transmittance at 400 to 500 nm is 20% or less. As a material for reducing light in the ultraviolet region, a UV absorber which is generally blended in a plastic container for the purpose of preventing deterioration due to ultraviolet rays can be used. UV absorbers used for this purpose include p-t-butylphenyl salicylate, 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-octoxybenzophenone, and 2,2'-dihydroxy-4-methoxy. Benzophenone, 2- (2'-hydroxy-5'-methylphenyl) benzotriazole,
2- (2'-hydroxy-3'-t-butyl-5'-methoxyphenyl) -5-chlorobenzotriazole, 2
Examples thereof include, but are not limited to,-(2'-hydroxy-3 ', 5'-di-t-butylphenyl) benzotriazole. These ultraviolet transmittance inhibitors are blended so that the ultraviolet transmittance is 10% or less, and it is more preferable that the transmittance is 5% or less. Also,
Titanium oxide or the like having an effect of suppressing light in the entire light ray region may be added in such a range that the liquid surface of the content liquid can be seen through. As the components to be blended in these containers, those having little influence on the stability of the liquid bleaching agent composition to be filled are preferably used. 40
If the light transmittance of a wavelength of 0 to 500 nm exceeds 20% or the ultraviolet transmittance exceeds 10%, the decomposition of sodium hypochlorite due to light proceeds, and the concentration thereof decreases,
It cannot exert its function stably. Further, if visible light is completely suppressed, the stability of hypochlorite increases, but it becomes impossible to see through the liquid surface.

Examples of the resin for the container used in the present invention include polyethylene, polypropylene, vinyl chloride and polyethylene terephthalate. From the viewpoint of safety such as drop strength, a polyolefin resin is preferable, and a polyethylene resin is more preferable in consideration of low temperature drop.

Plastic additives such as a plasticizer, an antioxidant and an antistatic agent can be added to the plastic container used in the present invention within the range not hindering the present invention.

Examples of the hypochlorite used in the present invention include sodium hypochlorite and potassium hypochlorite, and sodium hypochlorite is particularly preferable. The content of hypochlorite in the bleaching detergent composition used in the detergent of the present invention is usually 0. 1-8
It is in the range of% by weight. If the content of hypochlorite is too low, the bleaching / cleaning power will be insufficient, and if it is too high, bleaching /
Detergency is not particularly improved.

The bleaching detergent composition used in the present invention is
Hypochlorite as an essential component, a stabilizer for the purpose of suppressing the decomposition of hypochlorite, specifically, an alkaline agent,
Chlorates, inorganic clay minerals and the like can be added. It is possible to add a surfactant, for example, an anionic surfactant, a nonionic surfactant, a cationic surfactant, etc., for the purpose of improving the permeability to the substance to be polluted or imparting the detergency. it can. In addition, aromatic sulfonates such as toluene sulfonate and xylene sulfonate, thickeners,
It is also possible to mix components such as a solvent, a dye and a fragrance. The amounts of these optional components to be compounded can be conventional amounts as long as the effects of the present invention are not impaired.

EXAMPLES Next, the present invention will be described with reference to examples, but the present invention is not limited to these examples.

[0012] A sodium hypochlorite preparation was put in a plastic container (replaced contents are used) and a polyethylene prototype container used for a commercially available detergent, and light stability, liquid transparency and a light ray having a wavelength of 400 to 650 nm are used. The transmittance and the ultraviolet transmittance were examined.

(Test Method) (Measurement of Light Transmittance) Commercially available and polyethylene prototype containers of each color shown in Table 1 were thoroughly washed with water and dried, and then test pieces for measurement were cut out to obtain Hitachi spectrophotometer U-3410. use,
The light transmittance at each wavelength was determined.

(Light Stability of Sodium Hypochlorite) A 3% aqueous solution of sodium hypochlorite and a 1% aqueous solution of sodium hydroxide were prepared and filled in each plastic container, and the plastic container was exposed to direct sunlight during the day. After 1 week, the amount of sodium hypochlorite was analyzed and the decomposition rate (%) was determined by the following formula (1). Decomposition rate (%) = (B−A) / B × 100 (1) (A is the concentration of sodium hypochlorite after being left outdoors for 1 week,
(B is the sodium hypochlorite concentration at the time of preparation)

(Liquid see-through property) Tap water was put in a plastic container and visually evaluated according to the following evaluation criteria. ○: Clearly understand the liquid amount △: If you look closely you can see the liquid amount ×: Do not know the liquid amount

[0016]

[Table 1]

As is clear from the results shown in Table 1, 400 to 5
The polyethylene prototype container 1 (yellow) of Example 1 and the polyethylene prototype container 2 (yellow) of Example 2 having a light transmittance of 00 nm of 20% or less are transparent to the liquid surface and the light stability of sodium hypochlorite. While achieving both, 400 to 50
The commercial range cleaner container of Comparative Example 1 having a light transmittance of 0 nm of 20% or more and the flooring container of Comparative Example 2 had a decomposition rate of sodium hypochlorite of 10% or more when left outdoors for one week. . Further, in Comparative Example 4 in which only the UV absorber was blended, the decomposition rate was lower than that in Comparative Example 3 in which nothing was blended, but the decomposition rate was considerably high at 45%. Comparative Example 5 containing 4% titanium dioxide transmits almost no light, so that the light stability of sodium hypochlorite is good, but the liquid surface cannot be seen through.

Practical use test: A prototype polyethylene container (yellow) of Example 2 was filled with a stock solution of a commercially available fungicide containing hypochlorite, and was placed outdoors 3
After leaving it for a month, it was treated with mold growing on the joints of tiles, and a good mold bleaching effect was observed. On the other hand, the same test was carried out in the polyethylene prototype container (natural) of Comparative Example 3, but the mold could not be bleached.
