2. Description of the Related Art Hydrogen peroxide, percarbonate, persulfate, persulfate, chlorinated isocyanuric acid, hypochlorite, etc. are known as oxidation type bleaching detergents for mold removal. is there. Among them, hypochlorite is most frequently used as a chemical having a strong detergency and effective for mold bleaching. It is basically used as a liquid in a mixed aqueous solution of sodium hypochlorite and sodium hydroxide, some of which allow it to be sprayed for convenience of use.

However, whether they are used as liquids or sprayed, they are still used in the form of liquids, and when they are applied to the target wall surface by coating or spraying, the wall surface usually becomes Since it is a vertical surface, it drips from the wall surface, and the bleaching / cleaning efficiency is low. Further, when such a bleaching detergent is sprayed into the air in a closed space at home or the like, mist-like droplets drift in the space, and there is a great concern about inhalation or sticking to the skin, which is not preferable. In addition, when the mist is formed, the smell becomes stronger, which is a cause that the user dislikes.

As a countermeasure against such a problem, there has been proposed a method in which the above-mentioned bleaching detergent is sprayed in the form of foam utilizing the structural characteristics of a trigger type sprayer. , Naturally,
Bleach washing efficiency remains low. Furthermore, as an improvement measure, an attempt has been made to increase the adhesion by adding a polymeric thickener to increase the viscosity. But not enough to prevent dripping.

Embodiments of the present invention will be described below in detail. The bleaching detergent for mold removal and the like according to the present invention is basically a composition containing an oxidized bleaching detergent having a bleaching and cleaning action and a swelling clay mineral, and more specifically, hypochlorous acid. Salt 0.1-4 wt%, alkaline substance 0.1-1 wt%, and swelling clay mineral 0.1-15
wt.%, comprising a composition comprising:
The gel is formed into a gel having a viscosity necessary to maintain a state of adhering to the wall surface to be bleached and washed for at least a time required for the bleaching and cleaning.

The hypochlorite used here includes sodium hypochlorite, calcium hypochlorite, sodium chlorite and the like. In addition, hydrogen peroxide and peroxide, which are oxidizing bleaching agents having a bleaching action, are used. Sodium carbonate, sodium persulfate, sodium persulfate, potassium persulfate, chlorine dioxide, chlorinated isocyanuric acid, and the like can be used instead. Among them, sodium hypochlorite is most preferable, and 0.1 to 4% by weight is blended in the composition. If the content is less than 0.1 wt%, sufficient detergency cannot be obtained, while if the content is more than 4 wt%, there is a high possibility that problems will occur in relation to the material of the partner and safety. The mixing ratio of the above hypochlorite and the like is more desirably 1.5 to 3 wt% of hypochlorite, 0.3 to 0.8 wt% of an alkaline substance (sodium hydroxide), and a swelling clay mineral (smectite). ) 6 to 10 wt%.

As the alkaline substance, sodium hydroxide, potassium hydroxide, potassium silicate and the like are suitable, and among them, sodium hydroxide is preferable. 0.1-4
Although the pH is maintained in the range of wt% to stabilize sodium hypochlorite, use of a large amount affects the swelling stability of the swellable clay mineral.

The swellable clay mineral used as the inorganic thickener is a mineral or an inorganic substance which swells and disperses in water or another solvent to form a sol-gel, and is a purified bentonite product, swellable mica, or other layered material. Structural minerals may be used. For example,
Kaolinite, halocite, dickite, nacrite and other kaolin minerals (two-layer structure), or saponite, nontronite, hectorite and other montmorillonite, smectite, muscovite, biotite, chlorite, etc. Layered clay minerals and mixed layer types such as mica and vermiculite, kaolin mineral and smectite, illite and smectite, chlorite and smectite, among which smectite (Na0.3
3 (Mg2.67Li0.33) Si4O10 (O
H) 2) is optimal. 3 within the range of 0.1 to 15%
Any practical viscosity can be obtained by the balance of the components.

The arbitrary viscosity referred to herein means a viscosity of about 100.
It indicates that it can be adjusted from cP to 1 × 105 cP, but the viscosity that can withstand practical use is that when a bleaching detergent is applied to the vertical tile surface, it can be held for about 20 hours without dripping at all. Range (about 1000-
50,000 cP), and can be determined by examining factors such as retention of the state of adhesion to the target wall surface (the degree of dripping), bleaching detergency, safety, and usability.

If necessary, flavors, pigments and other inorganic powders can be added within a range that does not react with hypochlorite or sodium hydroxide. Further, the bleaching detergent is desirably placed in a tubular container provided with a cap having a protruding tip, so that it can be easily extruded into a required narrow portion such as a joint in actual use.

In the bleach-washing method of the present invention using the above-described bleach-washing agent, the high-viscosity gel-like bleaching-washing agent is adhered to the wall surface to be bleach-washed by any means, and the bleach-washing with the bleach-washing agent is carried out. This is performed by keeping the bleaching detergent adhered to the target wall surface due to its own viscosity over the required time. In this case, the bleaching detergent is formed in a high-viscosity gel that does not scatter in the air. Not only does it have no adverse effect on the human body, it can also prevent the bleaching washing efficiency from lowering due to dripping.By simply applying it to the target wall such as a tile and leaving it for the required bleaching washing time, Excellent bleach washing can be performed safely and efficiently.

The viscosity of the above-mentioned bleaching detergent needs to be maintained at least on the target wall surface for the time required for the bleaching washing. It is determined based on the time required for bleaching and washing in accordance with the difficulty of bleaching and washing the wall surface. For example, if bleaching and washing requires a time of about 30 minutes, the bleaching detergent will have at least 30 minutes of dripping. It is necessary to have a viscosity that can be retained on the target wall without performing, and if washing and bleaching requires all day and night, it is necessary for the bleaching detergent to have a viscosity that hardly drips over time.
