Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an agent and a method for effectively removing allergens that are difficult to remove by ordinary cleaning, and more particularly to a carcass of mite or feces, and spores of mold. , An agent and a method for efficiently removing allergen, which is a substance that becomes an allergic antigen such as pollen.

[0002]

2. Description of the Related Art Mite,
Chironomid, cockroaches, and their carcasses or their feces being dusted, broken pet hair, pollen, and mold spores are considered to cause allergic symptoms with these antigens, so-called allergens. The effects on the human body of people are becoming a social problem. Especially for mites, their breeding is promoted in exchange for a comfortable indoor environment, and the presence of causative substances for allergic diseases such as asthma, atopic dermatitis, and allergic rhinitis is becoming apparent. In particular, mites such as Dermatophagoides farinae, Dermatophagoides farinae or Dermatophagoides farinae inhabit and multiply in rugs such as tatami mats and carpets, blankets, beddings such as duvets, etc. Not only is there a great deal of interest in ordinary households. Many techniques have been proposed for anti-mitic agents and acaricides. For example, Japanese Patent Laid-Open No. 9-1571
No. 16 discloses an anti-mitic agent containing phenylisothiocyanate as an anti-mite component and containing a fragrance selected from a sesquiterpene compound, an alicyclic compound or an aromatic compound as a stimulating odor reducing component of phenylisothiocyanate. Have been described. However, carcasses and feces are also known to be allergens, and detoxification of these allergens is being studied.

Japanese Unexamined Patent Publication (Kokai) No. 6-279273 discloses a method for removing allergens using a specific compound such as gallic acid or its lower alcohol ester. JP-A-6
Japanese Unexamined Patent Publication No. 1-48421 discloses an allergen remover containing tannic acid and a specific solvent. Further, JP-A-2000-63207 discloses that a specific solvent is effective for detoxifying allergen.

As another technique related to allergen removal, Japanese Unexamined Patent Publication No. 2000-264837 discloses an allergen containing a compound using one or more selected from organic solvents, polyphenols such as tannic acid, hydroxyapatite and cationic surfactants. Described is an agent and a method for releasing a remover into fine particles and releasing it into a space, and removing the allergen by the released particles. Furthermore, the agent is retained and stored in a liquid, powder, sheet-shaped, or honeycomb-shaped carrier. There is described a method for removing allergen, in which air containing an allergen is passed and trapped in the container by physical suction. Similarly, JP-A-2002-128659 describes a method of spraying a solution or dispersion containing a house dust treating agent for inactivating or removing allergen with a specific spray particle size.

However, these conventional methods for removing allergens or agents for removing allergens are referred to as "elimination" to denature the protein and reduce its binding ability to the IgE antibody which causes allergen development to make it harmless. It is more correct to call it an allergen modifier. The publication also describes a method of adsorbing the allergen to fine particles such as particles of talc or water-swelling clay, or coating with a polymer compound such as polyvinyl alcohol, but any method can be used as long as it is not collected. However, since the allergen or the precursor thereof still remains after the treatment, the effect of the allergen cannot be sufficiently eliminated. Further, when repeatedly exposed to allergens modified by these techniques, the modified allergen itself becomes a new allergen substance, which may be a factor for the onset of allergy. Although the above-mentioned publication proposes a technique relating to collection, it aims at trapping allergens in the space and does not consider releasability from the treated surface.

On the other hand, it is known that it is effective to carefully clean mites and allergens derived from organisms such as mite feces, pollen and mold spores by using a cleaning tool such as a vacuum cleaner. However, rugs such as tatami mats and carpets, and beddings such as blankets and duvets cannot be easily removed because the allergen substances are present deep inside them. For example, cleaning the floor with a vacuum cleaner for more than 20 seconds per 1 m ² and with bedclothes carefully once a week are effective methods to effectively remove mite allergen from the indoor environment. However, it is very difficult to carry out on a daily basis. Therefore, a method for efficiently removing the allergen with a simple cleaning operation is required.

By the way, as a cleaning agent for carpets in which mites live, after spraying a powder impregnated with a cleaning liquid on the carpet, rubbing the powder with the carpet using a brush, and then sucking the powder with a vacuum cleaner. Methods of cleaning carpets are known. As another carpet cleaning agent, JP-A-53-130704 discloses a lithium salt of a sulfuric acid ester of a mixed alcohol obtained by blending 80 to 95 parts of lauryl alcohol and 5 to 20 parts of decyl alcohol. 70 P2O5 as a builder
There is described an invention of a liquid carpet shampoo composition containing water such that the total solid content of the composition comprising lithium salt of polyphosphoric acid of ˜85% is 10 to 40%, and further, the carpet shampoo. It is described that a product diluted with water is sprayed onto a carpet, spread on the carpet surface, and rubbed by brushing, and after drying, the cleaning liquid residue powdered is removed by vacuum. Further, JP-A-46-2934 discloses a water-soluble organic surfactant,
A cleaning composition used for carpets and the like composed of a higher swelling fatty alcohol and a water-insoluble silicic acid compound is described.
It is described that a foam comprising the composition is formed on a carpet, the foam disappears, and the foam is dried before being treated with a vacuum cleaner. Also, as a commercial carpet cleaner, after spraying a liquid detergent and polishing with a polisher,
There are products on the market that clean by sucking the powder after drying. As described above, a method of applying a powder or liquid for cleaning a carpet and sucking the dried powder with a vacuum cleaner or the like is already known. However,
These carpet washings are intended not to remove allergens but to remove carpet stains, and therefore use a surfactant or a powdery adsorbent as a main base material. However, for the purpose of removing allergens, it is desirable that the concentration of such a solid source be sufficient to obtain a sufficient effect, and if the concentration of the surfactant is high as in the conventional cleaning purpose, the treated surface is There is a problem that it is easy to remain in.

[0008] Therefore, the object of the present invention is to efficiently remove organisms such as mites and their allergen substances such as carcasses or feces that are difficult to remove by ordinary cleaning adhered to a solid surface by a simple cleaning operation, and to be treated. It is an object of the present invention to provide an allergen removing agent and an allergen removing method that do not change the feel of a material.

That is, the component (b) is a solid source substance which is dissolved in at least the component (a) or the component (c) in the allergen-removing agent and exists, and which produces an inorganic solid by evaporation of the liquid component in the removing agent. That is, the allergen remover of the present invention produces a solid by evaporation of the liquid component in the allergen remover.

The reason why the component (b) is defined in this way is that the feature of the present invention is that a solid is formed after drying. For example, when a plurality of compounds are blended, the pH is further adjusted. When adding an alkaline agent / acid agent for adjustment, or when using an ionic dissociative surfactant or organic acid salt together, the substance that precipitates as a solid may be different from the initially blended substance. Because there is. However, the present invention provides a non-deliquescent inorganic electrolyte [(b ')
Ingredients] is not denied. Of course, the precipitated inorganic solid may be the same as the inorganic electrolyte. In the present invention, “non-deliquescent” means a compound having a low hygroscopicity described later.

Here, the evaporation of the liquid component does not mean that all of the liquid component evaporates, but means the amount of evaporation of the liquid component sufficient for producing a solid. That is, the liquid component in the allergen remover of the present invention is mainly composed of (a) component and (c)
Although it is a component, when a small amount of a liquid component having low volatility such as a fragrance described later is included, these do not necessarily have to be evaporated.
