Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant, and more particularly to a novel deodorant effective for removing odors familiar to daily life such as dirt, body odor and indoor odor. The deodorant of the present invention also has an antibacterial action.

In recent years, as the standard of living has improved, interest in environmental hygiene has increased, and deodorization and deodorization have become major issues. As a method of reducing the malodorous component, including a method of masking the odor with a powerful fragrance,
Physical methods such as adsorption by porous adsorbents such as activated carbon, alumina, zeolite, catalytic combustion methods, oxidation methods by ozone, chemical methods such as neutralization methods using chemicals, or biochemistry such as decomposition by bacteria Methods are known.

Currently, as deodorants used in daily life, there are liquid deodorants by spraying, deodorants used in the form of gel or granules installed indoors, and the like. However, the most frequently used water-soluble liquid deodorant wets the surroundings and stains clothes, and is therefore not preferable as an artificial anus that touches the skin or clothes, or as a care product such as a diaper. Further, both the sheet in which the deodorant is impregnated and the activated carbon sheet have a sticky feeling, and the activated carbon sheet has no effect on the smell of ammonia.

As described above, none of the conventional deodorants has satisfactory performance. In addition, familiar malodors that are actually a problem in daily life are composed of various components such as acidic odors and basic odors, and there is a demand for an effective deodorant against any of these malodorous components. From this viewpoint, the present inventor previously proposed a deodorant using a specific maleic anhydride-based copolymer, and further, a fatty acid metal salt and an inorganic metal compound (JP 2000-225180, Japanese Patent Application No. 2000-225180). 2000-142705).

If the amount of these metal compounds used is larger than the above range, the derivative of the copolymer obtained will be insoluble in water, making it difficult to coat a non-woven fabric or the like. On the other hand, when the amount of the metal compound used is less than the above range, the reactivity with respect to hydrogen sulfide and the like decreases and the deodorizing function becomes poor. The deodorant antibacterial agent of the present invention has few carboxylic acid groups, is near neutral, and is mild, and has high reactivity to ammonia and mercaptan. Also, because metals such as copper and zinc are bound to the polymer,
The deodorant has excellent durability as compared with the case where these metals are mixed as a mixture.

The solvent used in the above reaction is
Examples include water and ethyl alcohol. The copolymer can be used as a deodorant antibacterial agent after reaction with a metal compound, as it is, or after purification by filtration or the like.

Although the above-mentioned polymer copolymer itself has been publicly known, its metal derivative has an excellent deodorizing action and antibacterial action against various malodorous components, and these are used as active components. No deodorant or antibacterial agent has been reported so far.

(B) Gluconic Acid Metal Salt As the gluconic acid metal salt such as copper gluconate and zinc gluconate, commercially available products can be used. The amount of these gluconic acid metal salts to be compounded is 1 to 20 parts by weight, preferably 2 to 15 parts by weight, based on 100 parts by weight of the metal derivative of the copolymer.

(C) Fatty Acid Metal Salt In another invention of the present application, a fatty acid metal salt may be used in combination with the copolymer. As such a fatty acid metal salt, a saturated or unsaturated fatty acid metal salt having 1 to 30 carbon atoms is used. Examples of fatty acid metal salts include saturated fatty acids such as acetic acid, propionic acid, undecylenic acid, palmitic acid, lauric acid, myristic acid, palmitic acid, stearic acid, and behenic acid; or oleic acid, sorbic acid, linoleic acid, linolenic acid, ricinol.

The compounding amount of these compounds is 1 to 200 parts by weight, preferably 5 to 80 parts by weight with respect to 100 parts by weight of the copolymer.
Parts by weight.

The cause of the bad odor such as diapers is a mixture of an amine compound and a sulfur compound such as mercaptan and hydrogen sulfide. For amine compounds that cause the main malodor around the body (such as amines and decomposition products thereof such as ammonia), an α-olefin-maleic anhydride polymer itself can provide an excellent deodorizing effect, When a sulfur-based compound such as mercaptan or hydrogen sulfide coexists, effective deodorization can be performed only by the α-olefin-maleic acid metal salt copolymer of the present invention.

The gluconic acid metal salts such as copper gluconate not only improve the deodorizing ability of sulfur odors such as hydrogen sulfide and mercaptan and nitrogenous odors such as ammonia, but also improve the water solubility of the deodorant. Contribute to.

Further, when the sulfur-based compound has a high concentration, it is preferable to use a fatty acid metal salt, an inorganic metal compound or a carbonyl compound in combination. By using these together with the derivative of the above-mentioned copolymer, nitrogen-based and sulfur-based compounds can be obtained. Both odors can be reliably removed.

In the production of the deodorant antibacterial composition of the present invention, a copolymer which is a deodorant component, further copper gluconate,
The solvent used for mixing the fatty acid metal salt, the inorganic metal compound, the carbonyl compound and the like is not particularly limited as long as it can dissolve these, and for example, dimethylformamide,
Examples thereof include dimethyl sulfoxide and water. The amount of these solvents used is 2 to 50 with respect to 1 part by weight of the deodorant component.
Parts by weight are preferred.

The deodorant antibacterial agent of the present invention is further blended with various adhesive materials in order to adjust the texture and appearance, or to be attached to and applied to a substrate composed of a sheet-shaped or thread-shaped molded product. May be. Appropriate polymer compounds can be used as such a material, for example, vinyl acetate-acrylic copolymer, polyvinyl alcohol, urethane resin,
Examples thereof include ethylene-vinyl acetate copolymer and carboxymethyl cellulose. These may be used alone or in combination. The blending amount of these adhesives is preferably 10 to 200 parts by weight with respect to 100 parts by weight of the deodorant component.

In the actual use, the deodorant antibacterial agent is applied in layers on various shapes of base materials or impregnated with it to increase the surface area of the deodorant antibacterial agent to improve the deodorant effect. As a deodorant antibacterial material, it can be used for diapers and sanitary products. Such substrates include non-woven fabrics (cotton, rayon, polypropylene, polyethylene, polyester, acrylic fibers), woven fabrics, threads, fibrous materials such as monofilaments, granules, paper or zeolite, sepiolite, diatomaceous earth, activated carbon, etc. A porous material or the like is used alone or in combination, and a cotton non-woven fabric is particularly preferable because it has good hygroscopicity. In addition, in the case of paper-like material, it is preferable to use a porous material and pulp together.

The amount of the deodorant of the present invention used in the deodorant antibacterial material is 0.1 to 50 parts by weight, preferably 10 to 20 parts by weight, based on 100 parts by weight of the substrate. The amount of the deodorant antibacterial agent applied to or impregnated on these base materials is 0.1 to 100 g / m ^{2 in} the case of a sheet when expressed in terms of area ratio.
It is a degree. Further, in the case of thread-like or granular (powder-like), it is about 0.1 to 50% by weight with respect to the base material.

Further, this deodorant composition may be incorporated into a non-woven fabric or paper. The mixing ratio of the deodorant component to the non-woven fabric and the paper is 0.1 to 50 parts by weight, preferably 1 to 20 parts by weight with respect to 100 parts by weight of these. If it is less than this range, the deodorizing effect cannot be obtained, and if it is more than this range, it is difficult to manufacture nonwoven fabric and paper.

The material of the paper is preferably made from pulp, and the ratio of pulp or linter in the whole paper is 5
It is 0 to 99% by weight. As the non-woven fabric, it is preferable to use pulp / cotton, polyethylene, polypropylene, acrylic, rayon or the like, and it is preferable to use at least 30% by weight of pulp or cotton. In this way, the odor can be comfortably removed without wetting the futon as in the conventional liquid deodorant.

Another form of the deodorant antibacterial composition of the present invention is to disperse or mix in various polymer compounds, or to form a polymer blend by compatibility with a base polymer,
It may be formed into a sheet, a film or the like.

For example, 0.01 to 30 parts by weight, preferably 0.1 to 6 parts by weight, is added to 100 parts by weight of an olefin polymer such as polyethylene or polypropylene, and the mixture is molded by a known method. It should be a film. If the compounding amount of the deodorant composition is less than this, the desired deodorizing effect cannot be obtained, while if it is more than this, the resins do not dissolve each other and it is difficult to form a film. If you put dust, dirt, etc. in a bag made of such a film and seal it, when the odor-causing substance from the contents penetrates the film, it is absorbed and decomposed by the deodorant in the film and no bad odor is released to the outside. . Such a film is particularly useful as a dust bag, a waste bag, a deodorant bag for a diaper after use, a bag for storing raw food such as fish.

(Production Method) To produce the deodorant of the present invention, a copolymer having the structural units of the formulas (1) and (2) and a metal compound such as copper oxide or zinc oxide are prepared as described above. Are mixed in a solvent and heated to produce a metal derivative of a copolymer. As the reaction progresses, the cloudy reaction solution turns transparent and p
H rises. After completion of the reaction, a solvent may be added to adjust the concentration, and if desired, a gluconic acid metal salt, a fatty acid metal salt, an inorganic metal compound, etc. may be further added and dissolved by heating to serve as a deodorant.

Next, if necessary, an adhesive such as a vinyl acetate-acrylic copolymer emulsion is added and uniformly mixed to obtain a solution of the deodorant composition. This solution is impregnated into a sheet-shaped or thread-shaped substrate or applied, and then heated and dried to obtain a deodorant.
