Description

    TECHNICAL FIELD
  • The present invention relates to a novel deodorant composition. Specifically, it relates to a novel deodorant composition comprising a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more. Precisely, it relates to a novel deodorant composition comprising a colored compound obtainable by reacting a specific polyphenol in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more and to a novel deodorant composition comprising a colored compound obtainable by reacting a specific polyphenol and an amino acid in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more. More precisely, it relates to a novel deodorant composition to be used for elimination or reduction of odors felt in daily life, such as bad breath (halitosis), body odor, odor in refrigerator, odor of raw garbage, odor of footwear cupboard, body odor of human and animals, odor of feces and urine of human and animals, odors in factories and industrial wastes.
    • BACKGROUND ART
  • Recently, with diversification of lives, improvement of life level, changes and improvement of attitudes, and the like, attention has been paid to various points around one's life. One of them is existence of various malodors. Main malodorous components to be targeted include nitrogenous compounds such as ammonia, urea, indole, skatole, and amines; sulfur compounds such as methyl mercaptan, hydrogen sulfide, and dimethyl sulfide; and lower fatty acids such as butyric acid. Hereto fore, there are a number of reports on deodorants that are used to eliminate or reduce the malodors.
  • For example, JP-A-11-319051 discloses a deodorant containing a polyphenol component extracted from apple as an active component. However, the deodorant is insufficient in the deodorizing effect. Moreover, a deodorant composition containing a plant extract and a phenol oxidase as components is also known (cf. e.g., JP-A-9-38183, JP-A-10-212221, and so forth). However, although these deodorants are excellent in the deodorizing effect, they have a problem that preparation processes thereof are rather complicated.
  • On the other hand, there is a report in Food. Sci. Technol. Res., 6(3), 186-191, 2000 that the deodorizing effect of a specific polyphenol is confirmed in an NH4OH solution or in an NaHCO3 solution. Moreover, in Biosci. Biotechnol. Biochem., 65(10), 2121-2130, 2001, there is a report that a colored compound can be prepared by reacting a caffeic acid ester and an amino acid.
  • As the deodorant composition, there is desired a deodorant composition capable of maintaining a deodorizing ability for a long period of time as far as possible. Moreover, a deodorant composition having an excellent deodorizing effect on various malodorous components such as nitrogenous compounds, sulfur compounds, and lower fatty acids is expected.
    • DISCLOSURE OF THE INVENTION
  • An object of the invention is to provide a novel deodorant composition which is excellent in the deodorizing effect and obtainable by a simple process. Moreover, it is to provide a novel deodorant composition which shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Furthermore, it is to provide a deodorant composition having an excellent deodorizing effect on a wide range of malodorous components.
  • As a result of the extensive studies for solving the above problems, the present inventors have found that a colored compound obtainable by reacting a specific polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more has an excellent deodorizing effect. Also, they have found that a colored compound obtainable by reacting a specific polyphenol and an amino acid in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more has an excellent deodorizing effect. Furthermore, even when a composition containing the deodorizing component is stored for a long period of time, the deodorizing effect of the deodorant composition is maintained for a long time. As a result of further studies, they have finally reached the present invention.

  • Of these, particularly, glycine, alanine, glutamic acid, aspartic acid, lysine, arginine, histidine, serine, cystine, methionine, cysteine, sodium glutamate, sodium aspartate, and tyrosine are preferred.
  • These amino acids can be easily available by purchasing commercially available products. Moreover, these amino acids may be used solely or as a mixture of two or more of them. Furthermore, a plant extract containing an amino acid can be also employed.
  • In addition, the deodorant composition of the invention can be also obtained by employing a plant extract containing substantially no polyphenol and containing an amino acid instead of an amino acid and a polyphenol in combination. The “plant extract containing substantially no polyphenol and containing an amino acid” herein can be prepared by a known method but a commercially available product can be purchased. In this connection, it is also possible to use an amino acid and an amino acid-containing plant extract containing substantially no polyphenol in combination.
  • At obtaining the deodorant composition in the invention, examples of using a polyphenol and an amino acid in combination also include an example of using an amino acid-containing plant extract containing substantially no polyphenol and a polyphenol in combination, an example of using a polyphenol-containing plant extract containing substantially no amino acid and an amino acid in combination, and an example of using a polyphenol-containing plant extract containing substantially no amino acid and an amino acid-containing plant extract containing substantially no polyphenol in combination.
  • The mixing ratio of the polyphenol to the amino acid in the deodorant composition can not be prescribed unconditionally since the ratio varies depending on the polyphenol to the amino acid to be adopted but the polyphenol and the amino acid are preferably mixed in a ratio of 9:1 to 1:9, more preferably in a ratio of 3:1 to 1:3 by mol. In this connection, the prescription is determined for the purpose of effectively utilizing the polyphenol and the amino acid in the case that they are used as raw materials, and the case that either of both substances is present in excess is not excluded.
  • The deodorant composition of the invention can be prepared by reacting a polyphenol or a polyphenol and an amino acid in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more.
  • The solvent showing alkalinity is a known one and is representatively an alkaline substance-containing solvent wherein an alkaline substance is dissolved in a solvent such as water.
  • The alkaline substance is not particularly limited and specifically includes carbonate salts or hydrogen carbonate salts such as sodium carbonate, potassium carbonate, sodium bicarbonate, ammonium carbonate, and guanidine carbonate; borate salts such as potassium borate and sodium borate; silicate salts such as potassium silicate, sodium silicate No. 1, sodium silicate No. 2, sodium silicate No. 3, sodium orthosilicate, and sodium metasilicate; sodium monohydrogen phosphate, sodium sulfite, sodium hydroxide, calcium hydroxide, potassium hydroxide, magnesium hydroxide, ammonium hydroxide, sodium pyrophosphate, and potassium pyrophosphate; and the like.
  • The solvent for dissolving one or two or more these alkaline substances includes water and various hydrous solvent as preferable solvents. Moreover, so-called alkaline buffer solutions using these alkaline substances and acids may be also employed.
  • The above solvent usually show alkalinity and it is alkaline before the reaction but sometimes shows weak acidity depending on the substance to be incorporated into the solvent and an added amount thereof. Namely, when the solvent before the reaction is necessarily alkaline and, at obtaining the above deodorant composition, the pH of the solvent in the reaction system after the start of the reaction is 6.5 or more, then a preferable result is obtained. In particular, the pH of the reaction system is preferably in the range of 7 to 13, further preferably in the range of 8 to 13. When the pH in the reaction system during the reaction is below 6.5, it is impossible to afford a deodorant composition having a preferable deodorizing effect.
  • In the invention, it is necessary to react the polyphenol in the coexistence of oxygen molecules. As a conventional means for supplying oxygen molecules into the reaction system, there may be mentioned supply of oxygen or air into the system utilizing an air pump (bubbling) or active stirring of the system. The reaction in the coexistence of oxygen molecules means a reaction aiming at the acceleration of the reaction of the polyphenol present in the reaction system by actively incorporating oxygen molecules into the reaction liquid. In this case, the deodorant composition can be efficiently obtained by making the oxygen supplying amount into the reaction liquid 1 mg/L or more, preferably 2 mg/L or more. The oxygen supplying amount can be achieved by, for example, actively blowing oxygen gas, air, or a mixture thereof into the reaction system (bubbling) or it can be also achieved by stirring the reaction liquid under a reaction condition that oxygen gas or air can constantly come into contact therewith.
  • With regard to the temperature at the reaction, the inventive product can be obtained at a temperature of 0° C. to a reflux temperature of the solvent but in order to avoid thermal decomposition of the resulting deodorizing active component, the reaction is carried out at a temperature of preferably 0° C. to 60° C., more preferably 0° C. to 40° C., further preferably 0° C. to 25° C.
  • In the invention, the polyphenol reacts within a short period of time but from a practical viewpoint, the reaction may be carried out for preferably from several minutes (2 minutes) to about 24 hours, more preferably from about 10 minutes to about 9 hours, further preferably from 10 minutes to 7 hours. At the reaction for preparing the above deodorant composition, pressurization is not particularly necessary but pressure may be applied.
  • Moreover, when the reaction is carried out in the coexistence of a metal ion or a metal salt which releases a metal ion into the reaction system, a more excellent deodorant composition exhibiting an enhanced deodorizing activity and stability can be obtained.
  • As a preferable metal ion, there may be mentioned a copper ion, a zinc ion, a calcium ion, a magnesium ion, a silver ion, a tin ion, an aluminum ion, or a manganese ion.
  • Examples of the compound which releases a metal ion include the following: e.g., copper compounds such as copper chloride, copper fluoride, copper sulfate, copper nitrate, copper hydroxide, copper citrate, copper gluconate, copper aspartate, copper glutamate, sodium copper chlorophyllin and copper chlorophyll; zinc compounds such as zinc chloride, zinc fluoride, zinc sulfate, zinc nitrate, zinc hydroxide, zinc citrate, zinc gluconate, zinc aspartate, zinc glutamate, zinc phosphate, and zinc lactate; calcium compounds such as calcium chloride, calcium hydroxide, calcium citrate, calcium gluconate, calcium L-glutamate, calcium carbonate, calcium lactate, calcium pantothenate, calcium dihydrogen pyrophosphate, calcium propionate, calcium sulfate, tricalcium phosphate, calcium monohydrogen phosphate, calcium dihydrogen phosphate, and disodium calcium ethylenediaminetetraacetate; magnesium compounds such as magnesium chloride, magnesium sulfate, magnesium hydroxide, magnesium L-glutamate, magnesium oxide, and magnesium carbonate; silver compounds such as silver oxide; tin compounds such as tin chloride, tin acetate, and tin fluoride; aluminum compounds such as aluminum chloride, aluminum hydroxide, aluminum acetate, aluminum borate, aluminum phosphate, and aluminum sulfate; permanganese salts such as potassium permanganese, manganese compounds such as manganese sulfate, and the like. In addition, titanium compounds such as titanium dioxide can be also employed.
  • The addition amount of the metal ion varies depending on the situation of the reaction but it is preferable to add the ion so that the concentration of the metal ion in the reaction liquid becomes 0.00001 mM to 100 mM and the concentration is more preferably from 0.00005 mM to 10 mM, further preferably from 0.1 mM to 5 mM.
  • Moreover, in the invention, after a deodorant composition is obtained by reacting a polyphenol or a polyphenol and an amino acid in an alkaline solvent in the coexistence of oxygen molecules, a metal ion may be added thereto to form a deodorant composition.
  • In the invention, at obtaining the deodorant composition by reacting a polyphenol and an amino acid in an alkaline solvent in the coexistence of oxygen molecules, a plant extract containing a polyphenol and an amino acid can be used instead of the polyphenol and the amino acid. As the plant extract in this case, a plant extract containing a polyphenol and an amino acid in a high concentration may be mentioned. As the plant extracts, those prepared by known methods may be used or commercially available ones may be used.
  • For example, the deodorant composition of the invention can be also obtained by adding a plant extract containing a polyphenol and an amino acid, i.e., an extract from at least one portion selected from leaves, stems, roots, fruits, and the like of a plant to a solvent showing alkalinity, adjusting the reaction liquid during the reaction to pH 6.5 or more, and treating it at an oxygen supplying amount of 1 mg/L or more at a reaction temperature of 0° C. to a refluxing temperature of the solvent for a reaction time of several minutes to 24 hours. Examples of the alkaline substance and solvent in this case include those described in the above and the composition is obtained by operating the reaction under the same conditions as described above. In the case that the plant extract containing a polyphenol and an amino acid is used instead of the polyphenol and the amino acid, at least one selected from a polyphenol-containing plant extract containing substantially no amino acid, an amino acid-containing plant extract containing substantially no polyphenol, a polyphenol, and an amino acid may be further used in combination. Examples of the plant extract will be shown below.
  • Moreover, in the invention, at obtaining the deodorant composition by reacting a polyphenol and an amino acid in an alkaline solvent in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more, a plant body containing a polyphenol and an amino acid can be also used instead of the polyphenol and the amino acid. The plant body in this case is preferably one containing a polyphenol and an amino acid in a high concentration.
  • For example, the deodorant composition of the invention can be also obtained by adding a plant body containing the polyphenol and the amino acid of the invention, i.e., at least one portion selected from leaves, stems, roots, fruits, and the like of a plant to a solvent showing alkalinity, adjusting the reaction liquid during the reaction to pH 6.5 or more, and treating it at an oxygen supplying amount of 1 mg/L or more at a reaction temperature of 0° C. to a refluxing temperature of the solvent for a reaction time of several minutes to 24 hours. Examples of the alkaline substance and solvent include those described in the above and the composition is obtained by operating the reaction under the same conditions as described above. As the plant body, plants exemplified in the following plant extract can be used. In the case that the plant body containing a polyphenol and an amino acid is used instead of the polyphenol and the amino acid, at least one selected from a polyphenol-containing plant extract containing substantially no amino acid, an amino acid-containing plant extract containing substantially no polyphenol, a plant extract containing a polyphenol and an amino acid, a polyphenol, and an amino acid may be further used in combination. Herein, the amount of the amino acid or polyphenol which is “substantially not contained” is an amount imparting no influence to the reaction and is an amount which is less than detection limit when measured according to a generally known method.
  • Examples of the plant extract include extracts obtainable from aloe, anise seeds, elder, eleutherococcus, psyllium, orange flower, allspice, oregano, valerian, chamomile, capsicum pepper, cardamon, cassia, garlic, caraway seeds, clove, cumin seeds, kola, coriander seeds, Rhus javanica, saffron, zanthoxylum, juniper berry, cinnamon, ginger, star anise, St. Johns wart, celery seed, savory, sesame, pieplant, tarragon, turmeric, thistle, Anethum graveolens, nutmeg, nettle, hibiscus, hamamelis, birch, basil, bitter orange, fennel, primrose, fenugreek, verbena, Laurus nobilis, hop, boldo, horseradish, poppy seed, gallnut, marigold, marrow, marjoram, mustard, Millefeuille, mint leaves, melissa, mace, lindane, Gentiana scabra var. buergeri, rosehip, rosemary, Rosmarinus officinalis, sunflower seeds, grape pericarp, apple, carrot leaves, banana, strawberry, apricot, peach, plum, pineapple, pear, persimmon, cherry, papaya, mango, avocado, melon, loquat, fig, kiwi, prune, blueberry, black berry, raspberry, cranberry, coffee beans, cacao beans, grape seeds, grape fruits seeds, pecan nut, cashew nut, chestnut, coconut, peanut, walnut, green tea leaves, black tea leaves, oolong tea leaves, tobacco, perilla leaves, garden thyme, sage, lavender, spearmint, peppermint, spotted thistle, hyssop, sweet basil, marigold, dandelion, artichoke, Matricaria chamomille, Agrimonia pilosa var. japonica, licorice, anise, yarrow, eucalyptus, wormwood, balm, Angelica pubescens, fenugreek, Capsicum annuum var. angulosum, fennel, red pepper, coriander seeds, caraway seeds, fennel seeds, ginger, horseradish, Origanum majorana, Origanum vulgare, mustard, parsley, pepper, savory, tarragon, queen lily, wasabi, dill seeds, citrus fruits, and the like. Two or more of these plant extracts may be used in combination.
  • At the preparation of the deodorant composition of the invention, additives already conventionally used may be coexisted in the reaction system.
  • For example, a polyphenol oxidase may be coexisted. Preferred enzymes include catechol oxidases, polyphenol oxidases, tyrosinases, laccases, peroxidases, and the like. The addition amount of the enzyme is not particularly limited but the enzyme is preferably added in such an amount that enzyme activity becomes 100 units or more per 100 mg of the polyphenol which is a substrate of the deodorant. In this connection, with regard to the unit of the enzyme activity, the case that the absorbance value at OD 265 nm is increased by 0.001 when the enzyme was reacted for 1 minute using (L)-dopa as a substrate under conditions of pH of 6.5 and a temperature of 25° C. is determined as 1 unit.
  • Thus, there is obtained the colored compound which is an active component of the deodorant composition of the invention. The color of the resulting reaction liquid widely varies depending on the kind of the polyphenol as a starting substance, the presence of an amino acid, the kind of the amino acid, and the ratio thereof. Moreover, since the density of the color also varies depending on the reaction time and pH, the color cannot be unconditionally prescribed.
  • For example, when the case of chlorogenic acid is described as an example, the color of the reaction liquid which is pale yellow at the initial stage of the reaction changes into brown with time and finally into dark brown. In the case of quercetin, the color of the reaction liquid which is pale pink at the initial stage of the reaction increases in red with time and finally into deep wine red. In the case of gallic acid, the color of the reaction liquid which is pale yellow at the initial stage of the reaction changes into greenish with time and finally into dark green. In the case of pyrocatechol, the color of the reaction liquid which is pale pink at the initial stage of the reaction changes into brown with time and finally into dark brown.
  • Moreover, in the case that glycine is selected as an amino acid and reacted, the reaction liquid with chlorogenic acid is green, the reaction liquid with (+)-catechin is red, the reaction liquid with protocatechuic acid is red, the reaction liquid with pyrocatechol is pale pink, the reaction liquid with aesculetin is brown, the reaction liquid with hydroquinone is brown, the reaction liquid with quercetin is red, and the reaction liquid with gallic acid is brown.
  • With regard to the reaction with a polyphenol or a polyphenol and an amino acid in most cases, the reaction liquid has a pale color at the initial stage of the reaction but the color of the reaction liquid is darkened and finally tends to become a dark color. The time required for darkening the color of the reaction liquid varies depending on the kind of the polyphenol, the combination of the polyphenol and the amino acid, and the reaction conditions but is about several minutes after the start of the reaction and sometimes about 20 minutes or 30 minutes.
  • As mentioned above, the deodorant composition prepared in the invention contains the colored compound. The colored compound acts a role as a deodorizing active component. The colored compounds have various chemical structures and, for example, reaction products of polyphenols which are starting materials, polymeric products prepared from polyphenols, reaction products from polyphenols and amino acids, polymeric reaction products prepared from polyphenols and amino acids, oxides of polyphenols, oxides of the above reaction products and polymeric products, and further various radicals such as a phenoxy radical which is one of oxidation products of polyphenols also belong to the category of the colored compounds of the invention.
  • The ratio of the colored compound contained in the deodorant composition of the invention is from 10 ppm to 100% by weight.
  • It is preferred that the molecular weight of the colored compound in the resulting deodorant composition exceeds the molecular weight of the polyphenol before the reaction as a starting material or the sum of the molecular weights of the polyphenol and the amino acid, and is 10,000 or less.
  • The molecular weight of the colored compound can be measured by the following method. Namely, the deodorant composition prepared by one of the above various methods is concentrated by centrifugation and it is determined whether the concentrate passes through or remains on a filtration membrane having a certain pores, whereby a corresponding molecular weight is determined based on the pore size of the filtration membrane on which the concentrate remains. As the filtration membranes to be used, commercially available products may be used.
  • The deodorizing active component in the invention may be an oxide of a starting material obtained by the reaction of the starting material with oxygen molecules, and hence the range of the molecular weight of the deodorizing active component is expressed as above.
  • The thus obtained reaction liquid containing the deodorizing active component can be used as the deodorant composition without further treatment. Alternatively, if necessary, by a method of further concentrating the reaction liquid containing the deodorizing active component or the like method, a deodorant composition having a high content of the deodorizing active component can be obtained. Furthermore, a solid deodorant composition can be obtained by removing liquid components from the reaction liquid containing the deodorizing active component by a known method such as a vacuum-drying method or a freeze-drying method. Alternatively, the liquid may be supported on any carrier such as a liquid, a solid, or a gel substance to form a deodorant composition.
  • Preferred examples of the liquid include water, hydrous alcohols, lower alcohols (methanol, ethanol, butanol, propanol, etc.), polyol-based organic solvents (ethylene glycol, propylene glycol, etc.), benzyl alcohol, glycerin, monoglycerides, diglycerides, animal and plant oils, essential oils, and the like.

They can be used solely or in combination.
  • As a method for supporting the deodorant composition of the invention on the carrier, there can be mentioned a method of attaching the deodorant composition in a solution state by means of coating, impregnation, spraying, or the like and subsequently drying (e.g., air-drying at 60° C. for 12 hours) as an example.
  • The deodorant composition of the invention may be used after capsulation by a known method using gelatin, gum arabic, sodium arginate, a cellulose derivative such as ethyl cellulose, polyvinyl alcohol, vinyl methyl ether-maleic anhydride copolymer, styrene-maleic anhydride copolymer, polyethylene, polystyrene, paraffin wax, or the like.
  • Moreover, particularly in the case that the deodorant composition of the invention is used in a solution state, the reduction of the amount of dissolved oxygen in the solution as far as possible remarkably enhances the storage stability of the composition of the invention in the solution and thus the case is convenient. A rough standard of the amount of dissolved oxygen convenient at storage is, for example, 0.0005% by weight, more preferably 0.00015% by weight or less.
  • As a method for the reduction of the amount of dissolved oxygen in the solution as far as possible, a known method may be employed, which specifically includes a method of storing the solution under a circumstance of reduced pressure, a method of subjecting the solution to degas treatment, a method of replacement with nitrogen gas or argon gas, a method of treating it under an atmosphere of nitrogen gas or argon gas, and the like.
  • In the case that the deodorant composition is used in a solid state, when a compound having deliquescence or high hygroscopicity is present together with the deodorant composition, the compound efficiently absorbs the moisture in the air and hence a reaction field suitable for the deodorant composition may be provided, so that the case is more preferred for exhibiting the deodorizing effect of the deodorant composition.
  • As examples of the compound having deliquescence or high hygroscopicity, salts and alkalis showing deliquescence by the moisture in the air or showing a property of strongly absorbing the moisture in the air are employed and particularly, salts having deliquescence or high hygroscopicity are practical.
  • Specific examples include lithium chloride, sodium chloride, potassium chloride, magnesium chloride, ammonium magnesium chloride, sodium magnesium chloride, potassium magnesium chloride, manganese chloride, potassium manganese chloride, antimony chloride, antimony cobalt chloride, zinc chloride, iron chloride, bismuth chloride, beryllium chloride, calcium bromide, zinc bromide, copper bromide, iron bromide, cobalt bromide, cadmium bromide, lithium iodide, sodium iodide, magnesium iodide, calcium iodide, iron iodide, nickel iodide, sodium nitrite, potassium nitrite, magnesium nitrite, ammonium nitrate, lithium nitrate, sodium nitrate, calcium nitrate, beryllium nitrate, magnesium nitrate, manganese nitrate, cerium nitrate, ammonium cerium nitrate, iron nitrate, copper nitrate, lithium chlorate, calcium chlorate, magnesium chlorate, zinc chlorate, cadmium chlorate, cobalt chlorate, copper chlorate, potassium carbonate, lithium sulfate, ammonium zinc sulfate, antimony sulfate, iron sulfate, ammonium cadmium sulfate, ammonium thiosulfate, potassium phosphate, ammonium phosphite, potassium phosphite, hydrazinium phosphite, sodium hypophosphite, potassium hypophosphite, sodium permanganate, calcium permanganate, strontium permanganate, magnesium permanganate, zinc permanganate, sodium hydroxide, potassium hydroxide, and the like. These salts may be used solely or two or more of them may be used in combination.
  • The most suitable amount of the compound having deliquescence or high hygroscopicity to be co-present varies depending on the kind of the compound, the environment to be applied, and intended use and hence the amount is not unconditionally determined but 0.1 to 10 weight equivalents to the deodorant composition may be mentioned as an example.

  • They can be mixed with the deodorant composition of the invention solely or as a combination of two or more of them and thus a characteristic deodorant composition and deodorant can be prepared. Particularly, when an antibacterial agent is mixed to the deodorant composition, the deodorizing effect is synergistically enhanced and hence it becomes possible to prepare a more characteristic deodorant composition and deodorant by combining the agent with other additives to exhibit performances of the additives. The mixing amounts of the above additives are not particularly limited as far as the amounts are such amounts that they can accomplish desired purposes.

  • In the case that chlorogenic acid and glycine were added to the buffer solution of pH 6.5 and reacted, the pH of the reaction liquid during the reaction was maintained at pH 6.5 and no deodorizing effect was observed at any reaction times.
  • On the other hand, even when the pH of the reaction liquid during the reaction was 6.5, a deodorizing effect was observed and a deodorant composition was formed in the case that the solvent before the reaction was alkaline and the pH became 6.5 as a result of the reaction with the addition of chlorogenic acid and glycine.
  • From Examples 19, 20, and 21, it is suggested that the formation of the deodorant composition does not depend on the kind and concentration of the alkaline solvent and the pH of the alkaline solvent before the reaction but it is an important factor to make the pH of the reaction liquid during the reaction 6.5 or higher by using the alkaline solvent with the pH of 7.0 or higher.
    • Example 22 Influence of Oxygen Supplying Amount
  • One mmol of gallic acid and 1 mmol of sodium glutamate were added to the inside of the reaction vessel containing 100 mL of a 0.05M sodium carbonate solution (pH 11.2), and the whole was stirred at each temperature described in Table 15 with continuously supplying air and the concentration of dissolved oxygen in the reaction liquid was measured with time. Moreover, in the case of 100 mL of a 0.05M sodium carbonate solution (pH 11.2) without adding gallic acid and sodium glutamate, the concentration of dissolved oxygen in the reaction liquid was measured with time in the same manner. The results are shown in Table 15.
  • The concentration of dissolved oxygen in the reaction liquid was measured using a dissolved oxygen measuring apparatus (manufactured by TOA Electric K.K., oxygen electrode: OE-2102) at 23.4° C. and 42.4° C. and using a Ponal Kit for measuring dissolved oxygen (manufactured by Dojindo Laboratories) at 60° C. and 80° C., and in boiling water.
  • With regard to the case after 3 hours of stirring at each temperature, as in Example 2, a deodorizing activity test was conducted. The results are shown in Table 16.

    Amount of dissolved oxygen in the reaction liquid (mg/L)
  • In the case of the solvent alone, at the measured temperatures except boiling temperature, the amount of dissolved oxygen reached equilibrium within 10 minutes of stirring but the amount decreased as the temperature was elevated. In the case that gallic acid and sodium glutamate were added and reacted, the amount of dissolved oxygen in the reaction liquid was 0 at any time. From these results, it is revealed that gallic acid and sodium glutamate rapidly consume dissolved oxygen when they are dissolved in an alkaline solvent and subsequently continue to consume it.

  • As a result of the deodorizing activity test at 3 hours of stirring with adding gallic acid and sodium glutamate, the deodorization rate was 100% in all cases at the reaction temperature other than boiling temperature but the deodorization rate was 25% in the case that the reaction was carried out at boiling temperature.
  • From the above results, it is suggested that the yield efficiency of the deodorizing effective component considerably decreases at the amount of dissolved oxygen in the case that the reaction was carried out at boiling temperature (0.5 mg/L).
    • Example 23 Measurement of Molecular Weight
  • One mmol of tannic acid and 1 mmol of sodium glutamate were added to the inside of a stirring vessel containing 50 mL of a 0.05M sodium carbonate solution (pH 11.2). The whole was stirred at 25° C. for 3 hours under a condition that it could come into contact with air and then allowed to stand to obtain a deodorant composition.
  • One mmol of gallic acid and 1 mmol of glycine were added to the inside of a stirring vessel containing 50 mL of a 0.05M sodium carbonate solution (pH 11.2). The whole was stirred at 25° C. for 3 hours under a condition that it could come into contact with air and then allowed to stand to obtain a deodorant composition.
  • Two grams of each resulting deodorant composition was subjected to centrifugal membrane filtration at 3,000 rpm for 1 hour. In the centrifugal membrane filtration, two kinds of filtration membranes were used, which were a filtration membrane whose separating molecular weight was 3,000 and a filtration membrane whose separating molecular weight was 10,000. In the filtration of separating molecular weight of 3,000, substances having a molecular weight of 3,000 or less were separated as the filtrate and substances having a molecular weight of more than 3,000 were separated as the filtration residue. In the filtration of separating molecular weight of 10,000, substances having a molecular weight of 10,000 or less were separated as the filtrate and substances having a molecular weight of more than 10,000 were separated as the filtration residue.
  • After the centrifugal membrane filtration, a deodorizing activity test was conducted on the filtrate and the filtration residue as in Example 2 to measure the deodorization rate. In this connection, the liquid obtained by dissolving the filtration residue in 2 g of water was referred to as a filtration residual liquid.
  • The results are shown in Table 17.

  • The same results were obtained in the cases of both of the deodorant composition derived from tannic acid and sodium glutamate and the deodorant composition derived from gallic acid and glycine. Namely, in the case of the centrifugal filtration apparatus for cutting molecular weight of 3,000, a strong deodorizing activity was observed on both of the filtrate and the filtration residual liquid. However, in the case of the centrifugal filtration apparatus for cutting molecular weight of 10,000, a strong deodorizing activity was observed on the filtrate but no deodorizing effect was observed on the filtration residual liquid. Based on the results, it is suggested that the molecular weight of the active component in the deodorant composition should be 10,000 or less.
    • Example 24 Reaction Temperature and Reaction Time at Preparation of Deodorant Composition
  • One mmol of gallic acid and 1 mmol of sodium glutamate were added to the inside of a reaction vessel containing 50 mL of a 0.05M sodium carbonate solution (pH 11.2). The whole was continued to stir at each temperature for each period of time described in Table 18 under a condition that it could come into contact with air. Two milliliters of the reaction liquid was sampled with time and the deodorizing activity was measured according to Example 2.

  • With regard to the relation between the reaction (stirring) temperature and the deodorizing activity, it is revealed that the deodorizing activity decreases as the reaction temperature is elevated. Particularly at a high temperature of 70° C. or higher, the deodorizing activity decreased when the stirring time was a long time. Therefore, the reaction temperature at which the yield efficiency of the deodorizing effective component is high is in the range of up to 60° C. The reaction (stirring) time is preferably about 7 hours. Moreover, at the reaction temperature of 80° C., the time up to 3 hours is suitable for the formation of the deodorizing effective component, wherein the deodorization rate of 100% is maintained.
    • Example 25 Influence of Metal Ion
  • In a reaction vessel, 1 mmol of chlorogenic acid, 1 mmol of sodium glutamate, 50 mL of a 50 mM Na2CO3 aqueous solution, and 0.25 mmol of each of various metal salts described in Table 19 were mixed. The whole was stirred at room temperature under a condition that it could come into contact with air or stirred under the same conditions and then allowed to stand to prepare a deodorant composition. The stirring time and the standing time were shown in Table 19. Moreover, “no addition” in the table means a deodorant composition prepared without adding any metal salt.
  • Using the above deodorant composition, the deodorization rate was measured in the same manner in Example 2. The results are shown in Table 19.

  • The pH in the table was a result observed after 3 days from the start of the reaction (stirring).
  • The color tone showed results observed after 3 days and 48 days from the start of the reaction (stirring).
  • In the case that a metal ion was added, durability of the deodorizing activity was observed as compared with the control (no addition of metal salt). Moreover, the deodorant compositions to which MgCl2, ZnCl2, or MnSO4 was added also exhibited an excellent effect on the stability of the color tone.
    • Example 26 Influence of Concentration of Metal Ion
  • In a reaction vessel, 1 mmol of chlorogenic acid, 1 mmol of sodium glutamate, 45 mL of a 50 mM Na2CO3 aqueous solution, and 5 mL of each of various concentrations of an MgCl2 aqueous solution described in Table 20 were mixed. The whole was stirred at room temperature under a condition that it could come into contact with air or stirred under the same conditions and then allowed to stand to prepare a deodorant composition. The stirring time and the standing time were shown in Table 20. Moreover, “no addition” in the table means a deodorant composition prepared without adding the MgCl2 aqueous solution.

  • The pH was measured after 3 days from the start of the reaction (stirring).
  • Even in the case that a 0.0005 mM MgCl2 aqueous solution was added, the deodorization rates after 13 days and 47 days were higher than the case of no addition and hence durability of the activity was enhanced by the addition of MgCl2.
    • Example 27 Deodorizing Effect on Each Malodor and Concentration of Deodorant Composition
  • One mmol of gallic acid and 1 mmol of sodium glutamate were added to the inside of a reaction vessel containing 50 mL of a 0.05M sodium carbonate solution (pH 11.2). The whole was stirred at 25° C. for 3 hours under a condition that it could come into contact with air. Then, the reaction liquid was freeze-dried to obtain a deodorant composition powder. The powder was dissolved in water to obtain a deodorant composition solution.
  • A deodorant composition solution having a deodorant composition concentration of 10.00 mg/mL was prepared and tests for the deodorizing effect of the deodorant composition solution on methyl mercaptan, ammonia, and isovaleric acid was conducted.
  • [Deodorization Test on Methyl Mercaptan]
  • The test was conducted in the same manner as in Example 2.
  • [Deodorization Test on Ammonia]
  • Into a 50 mL vial was placed 2 mL of the deodorant composition, and 5 μL of a 2.8% ammonia water was added thereto. Then, the vial was capped with Parafilm, followed by stirring at 25° C. for 10 minutes. Thereafter, 50 mL of the head space gas in the vial was passed through a gas detecting tube (manufactured by Gastech Corporation) to measure the concentration of the malodor component which remained in the gas, and a deodorization rate was calculated according to the expression shown in Example 2.
  • [Deodorization Test on Isovaleric Acid]
  • Into a 50 mL vial was placed 2 mL of the deodorant composition, and 40 μL of isovaleric acid was added thereto.

    • Example 45 Deodorizing Effect on Malodor Gas
  • One mmol of gallic acid and 1 mmol of glycine were added to the inside of a reaction vessel containing 50 mL of a 0.05M Na2CO3 solution (pH 11.2). The whole was stirred at 25° C. for 3 hours under a condition that it could come into contact with air and then allowed to stand to obtain a deodorant composition.
  • [Deodorization Test]
  • Into a 4 L odorless bag, 4 L of air was included by means of an air pump. Each malodor gas (ammonia, trimethylamine, hydrogen sulfide, or methyl mercaptan) was injected thereinto by an injection syringe to regulate a gas concentration. The bag was set at a test apparatus of closed circulation system fitted with an air pump and the air pump was worked at an air amount of about 1000 mL/minute. One milliliter of the above deodorant composition was supported on an absorbent cotton (0.2 g) and the cotton was set at the discharging side of the air pump. After 2 hours of working, the remaining amount of the malodor gas in the system was measured using a dedicated gas detecting tube (Gastech Corporation) and a deodorization rate was calculated according to the following expression.
  • As a comparative example, an absorbent cotton impregnated with 1 mL of a 20 mM aqueous solution of gallic acid was set at the discharging side of the air pump, instead of the absorbent cotton on which the above deodorant composition was supported. Then, the test was conducted similarly and the deodorization rate was calculated.
  • The results are shown in Table 43.
    Deodorization rate (%)=100×{1−(A/B)}
  • In the above expression, A means the measured concentration of the malodor components and B means the concentration of the malodor components measured in the control. The control is the case that an absorbent cotton was impregnated with 1 mL of water instead of 1 mL of the above deodorant composition.
