Description

  The present invention can suppress allergens such as pollen of vegetation such as cedar, mites, indoor dust, etc., and react with specific antibodies, and suppress allergens that are unlikely to cause unexpected or discoloration under daily use conditions. The present invention relates to an agent and an allergen-suppressed product obtained by treating the allergen inhibitor with an object.

  In recent years, many allergic diseases such as atopic dermatitis, bronchial asthma and allergic rhinitis have become a problem. The main causes of this allergic disease are mites living in the house, especially leopard mite allergens (Der1, Der2), which are abundant in indoor dust, and cedar pollen floating in the air mainly in spring. This is because allergens such as allergens (Cry j1, Cry j2) are increasing in the living space.

  Leopard mite allergens are not leopard mites themselves, but carcasses and feces of leopard mites become allergens, so even if you remove the leopard mites, it will not be a fundamental solution to allergic diseases.

  The cedar pollen allergens Cry j1 and Cry j2 are glycoproteins having a molecular weight of about 40 kDa and a molecular weight of about 37 kDa, respectively, and these cedar pollen allergens are in vitro as foreign substances when attached to the nasal mucosa. It is recognized and causes an inflammatory response.

  Therefore, in order to reduce the symptoms of allergic diseases or prevent new allergic symptoms, it is necessary to completely inactivate allergens from the living space or to inactivate allergens.

  Since allergen is a protein, it is considered that allergen loses allergenicity when it is denatured with heat, strong acid or strong alkali. However, allergens are very stable and are not easily denatured by oxidizing agents, reducing agents, heat, alkalis, acids, etc. that can be used safely at home (see Non-Patent Document 1).

  Further, when allergens present in an object that is contaminated with allergens are to be denatured, the objects that are contaminated with allergens, such as tatami mats, carpets, floors, furniture (sofas, cloth chairs, tables), bedding ( Beds, futons, sheets), interior items (seats, child seats), car interior materials (ceiling materials, etc.), kitchen items, baby items, curtains, wallpaper, towels, clothing, plush toys, other textiles, air purifiers (main unit) And filters) may be damaged depending on conditions.

  For this reason, a method of chemically modifying the molecular surface of the allergen under relatively mild conditions has been considered. For example, a method for suppressing allergen using tannic acid used for tanning of rawhide (Patent Document 1), a method for suppressing allergen using tea extract or the like (Patent Document 2), hydroxybenzoic acid A method for suppressing allergen using an acid compound or a salt thereof (Patent Document 3) has been proposed, and an allergen suppressing effect has also been confirmed.

  However, most of the compounds used in these methods are colored because they are a kind of polyphenol, and there is a problem in that the object is colored.

  Further, Patent Document 4 proposes a method for suppressing allergens using an aromatic hydroxy compound, and although the problem of coloring an object is improved, it is processed into a light-colored object such as white. In some cases, coloring may occur, which is not sufficient.

The Journal of Immunology Vol.144: 1353-1360 JP-A 61-44821 JP-A-6-279273 JP 11-292714 A JP 2003-81727 A

  Furthermore, it is preferable to contain a hydrophilic polymer in the allergen inhibitor. The hydrophilic polymer is preferably one that can form a reaction field that can cause interaction with the allergen inhibitor by collecting water molecules in the air.

By including a hydrophilic polymer in the allergen-suppressing agent, the allergen-suppressing agent further effectively suppresses the allergen even under normal humidity conditions, for example, in an atmosphere having an absolute humidity of 50 g / m ³ or less. be able to.

  The “reaction field that can interact with the allergen inhibitor by collecting water molecules in the air” refers to any chemical in order to suppress the antigenicity of the part (epitope) where the allergen exhibits antigenicity. This is a reaction field for exerting a chemical interaction, for example, by stabilizing the electrochemical transition state such as the ionized state and lowering the barrier energy of the transition state of the chemical reaction, the natural chemical reaction proceeds. A reaction field that can occur.

  And normally, liquid state water is required to lower the transition state energy barrier that must be exceeded to cause a chemical reaction, but as described above, the allergen inhibitor contains a hydrophilic polymer. By doing so, it becomes possible to collect moisture in the air, and the above-mentioned reaction field can be more reliably formed without requiring an operation such as artificially increasing the humidity.

  The hydrophilic polymer is not particularly limited, for example, a polymer having an ether bond and / or an amide bond in the main chain, a polymer having a polar group in the side chain, an ether bond and / or in the main chain.

Sodium polyacrylate, polyacrylamide, polyvinyl pyrrolidone are preferred. The hydrophilic polymers may be used alone or in combination of two or more, but it is preferable to combine two or more hydrophilic polymers having different molecular structures.

Specifically, polyoxyethylene and polyacrylic acid A combination with sodium and a combination of polyoxyethylene and polyvinyl alcohol are more preferable.

  If the melting point of the hydrophilic polymer is low, it may be in a liquid state under the use atmosphere, and there is a risk of damaging the texture, such as stickiness of an allergen-suppressed product obtained by treating the allergen inhibitor with the target. Therefore, it is preferably 40 ° C. or higher, and more preferably 50 ° C. or higher in order to maintain the allergen-suppressing effect when used in an atmosphere with many opportunities to come into contact with water.

  If the content of the hydrophilic polymer is small, water molecules in the air cannot be collected sufficiently, so that a reaction field sufficient to cause interaction with allergens cannot be formed, and allergen suppression is achieved. On the other hand, the agent may not be able to exert a sufficient allergen inhibitory effect, whereas if it is too much, the amount of the allergen inhibitor will be relatively reduced, and the allergen inhibitory effect of the allergen inhibitor may be reduced. Therefore, it is preferably 40 to 1000 parts by weight, more preferably 50 to 800 parts by weight, and particularly preferably 50 to 300 parts by weight with respect to 100 parts by weight of the total amount of the aromatic polyether compound and the aromatic hydroxy compound.

  Next, a method for treating an allergen inhibitor with an object to produce an allergen-suppressed product will be described. The allergen suppressing agent can be processed into an object such as daily necessities using a general-purpose usage method such as a spray type, an aerosol type, a smoke type, or a heat transpiration type to obtain an allergen suppressed product.

  An allergen inhibitor can be made into a spray type by dissolving or dispersing an allergen inhibitor in a solvent to make an allergen inhibitor solution, and adding an aqueous solvent, oil agent, emulsion, suspension, etc. to this solution. it can. In addition, a spray type means the usage method which applies a pressure to the allergen inhibitor solution under normal pressure, and sprays the allergen inhibitor in a mist form.

  Since the allergen inhibitor is excellent in stability when it is made into a suspension, it is suitable for use in treating objects such as daily necessities in a spray form such as a spray.

  Examples of the solvent include water (preferably ion-exchanged water), alcohols (such as methyl alcohol, ethyl alcohol, and propyl alcohol), hydrocarbons (such as toluene, xylene, methylnaphthalene, kerosene, and cyclohexane), and ethers. (Diethyl ether, tetrahydrofuran, dioxane, etc.), ketones (acetone, methyl ethyl ketone, etc.), amides (N, N-dimethylformamide, etc.) and the like.

  Then, by adding a solid carrier (talc, bentonite, clay, kaolin, diatomaceous earth, silica, vermulite, perlite, etc.) to the spray-type allergen inhibitor, the allergen inhibitor is made aerosol type. Can do.

  Here, the aerosol type is used in which an allergen inhibitor solution is sealed in a container together with a propellant in a compressed state, and the allergen inhibitor is sprayed in the form of a mist by the pressure of the propellant. Say the method. Examples of the propellant include nitrogen, carbon dioxide, dimethyl ether, and LPG.

  In addition, the above spray-type allergen suppressants include oxygen supply agents (potassium perchlorate, potassium nitrate, potassium chlorate, etc.), combustion agents (sugars, starches, etc.), and heat regulators (guanidine nitrate, nitroguanidine, phosphoric acid) An allergen inhibitor can be made into a smoke type by adding an auxiliary agent for decomposition of oxygen supply agent (such as guanylurea) and the like (potassium chloride, copper oxide, chromium oxide, iron oxide, activated carbon, etc.). The smoke type means a method of use in which an allergen inhibitor is made into fine particles to form a smoke and dispersed.

  And an allergen suppression product which can suppress an allergen is obtained by supplying an allergen inhibitor by spraying, dispersing, applying, or adhering to an object such as daily necessities according to various usage methods. .

  In the allergen-suppressing product, the allergen-suppressing agent contains a curing agent and crosslinks the aromatic polyether compound and the aromatic hydroxy compound, whereby a solvent such as water for the aromatic polyether compound and the aromatic hydroxy compound is used. Therefore, the allergen inhibitory effect of the allergen inhibitor can be maintained for a long period of time.

  For example, even if the allergen-suppressing product is splashed with water or the allergen-suppressing product is washed, the allergen-suppressing agent can be prevented from dissolving in the water and disappearing from the allergen-suppressing product. The allergen inhibitory effect can be maintained over a long period of time.

  The curing agent is not particularly limited as long as an aromatic polyether compound and / or an aromatic hydroxy compound can be cross-linked. For example, compounds such as amine compounds and polyaminoamide compounds synthesized from amine compounds, tertiary Examples include amine compounds, imidazole compounds, hydrazide compounds, melamine compounds, acid anhydrides, phenolic compounds, thermal latent cationic polymerization catalysts, photolatent cationic polymerization initiators, dicyanamide and derivatives thereof, and these are used alone.
