The fragrance seal using this long-lasting fragrance can be used easily and the effect can be maintained for a long time. Moreover, the production of the aromatic seals can be easily produced by printing, application is also wider ones.

It is sectional drawing of the fragrance seal of one Embodiment of this invention. It is a perspective view of the fragrance seal of this embodiment. It is the schematic which shows the testing apparatus used for the deodorizing test of the persistent fragrance | flavor containing the deodorizer which is one Example of this invention.

Hereinafter, an embodiment of a method for producing an aroma seal according to the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the fragrance seal 10 used in this embodiment is provided with a satin fabric 12 using a polyester fiber or the like as a base, and an acrylic adhesive 14 is applied to the back surface of the fabric 12. Yes. A release paper 16 is affixed to the exposed surface of the adhesive 14 layer.

  As shown in FIG. 2, the fragrance seal 10 is formed, for example, by punching a square fabric 12 into a circle by a slit 18 and a desired pattern 20 is drawn up to a slightly outer range of the circle. As long as this pattern is drawn, the persistent fragrance of the present invention is impregnated.

  The long-lasting fragrance of the present invention is obtained by dissolving essential oil as an aroma component in a medium in which a polysaccharide thickener and a binder such as a printing binder are mixed.

  As the thickener, sodium carboxycellulose is preferred. Sodium carboxycellulose is a substance for viscosity adjustment made from cellulose as a raw material, and is a kind of water-soluble cellulose derivative that dissolves in water and becomes a viscous liquid. It is a substance added to cosmetics and foods and used for stability and viscosity adjustment. Carboxycellulose sodium has protective colloidal properties in addition to viscosity, and has the property of stably dispersing fine particles. Protective colloid means that when a hydrocolloid is added to a hydrophobic colloid solution, the hydrocolloid is adsorbed to and surrounds the hydrophobic colloid particles, and the stability of the entire colloidal solution is improved because it becomes more like the properties of the hydrocolloid solution. .

  Other thickeners such as carrageenan, xanthan gum, guar gum, and pectin can also be used.

  As a fixing agent for printing or the like, a solution obtained by dissolving liquid paraffin (mineral oil) in a solvent made of mineral spirit is preferable. Liquid paraffin is a mixture of hydrocarbons, is a colorless and transparent liquid at room temperature, is colorless, tasteless and odorless, and has a lubricating action, permeability, softness, and plasticity. As the liquid paraffin solvent, in addition to mineral spirit, an aliphatic hydrocarbon solvent such as isoparaffin and isoaliphate may be used. In addition, aromatic solvents such as xylene and toluene may be contained. The fixing agent of this embodiment contains xylene in an amount of 0 to 1% by mass and mineral spirits in an amount of 25 to 35% by mass with respect to 1 to 5% by mass of liquid paraffin, and these are mixed with water and emulsified to have a viscosity. Use what has become liquid. This sticking agent is miscible with water and can be mixed well with a water-soluble thickener.

The medium in which the essential oil is mixed is a mixture of 20 to 70% by mass of the above-mentioned fixing agent with respect to a thickener such as sodium carboxycellulose, preferably 40 to 60% by mass, more preferably with respect to the thickener. What mixed 50 mass% fixing agent is used.

  Essential oils are organic compounds containing volatile aromatic substances that are contained in plants and are different from oils and fats. They are difficult to dissolve in water and have the property of being soluble in alcohol and fats (lipophilic and fat-soluble). . Plants from which essential oils can be obtained include rose, jasmine, neroli, chamomile, ylang ylang and the like as flowers and buds. Plants that can be removed from leaves and branches include geranium, eucalyptus, tea tree, and petit grain. There are citrus fruits such as sweet orange, bitter orange, lemon, lime and bergamot that can be removed from the skin. Examples of what can be obtained from fruits and seeds include juniper berries, vanilla, trees and bark, sandalwood (sandalwood), pine, cypress and cinnamon. Other essential oils that can be taken from resin are frankincense (milky incense, olivenum), myrrh (dissolved), roots and rhizomes that can be taken from vetiver, spikenard, orris root, whole grass, lavender, lemongrass , Basil, rosemary, mint and other herbs. In this embodiment, the essential oil is used in the above-mentioned medium by mixing 5 to 10% by mass of the medium.

  In the manufacturing method of the fragrance seal of this embodiment, first, a medium in which a thickener such as sodium carboxycellulose and a fixing agent for printing or the like are mixed in the above-described ratio is created. In this medium, 5 to 10% by mass of an essential oil as an aromatic component, for example, an essential oil of rose, is mixed to prepare a persistent fragrance.

  As a base material, first, a pattern suitable for the essential oil to be applied is printed on the surface of the fabric 12 such as satin. For example, if it is a rose essential oil, a rose flower pattern is printed. An adhesive 14 is applied to the back surface of the fabric 12 and a release paper 16 is attached. The pattern can be printed either before or after application of the adhesive, but the latter can suppress the volatilization of the essential oil until the packaging. An existing printing method is used as the printing method on the fabric 12. In particular, in the case of a small lot, an ink jet printer may be used. Further, the rectangular fabric 12 is punched into a predetermined seal shape. The punched part is a part with a pattern.

  The above-mentioned persistent fragrance is applied or printed on the pattern portion of the fabric 12 on which the pattern is printed. The coating or printing method is preferably by screen printing. In addition, spraying, ink jet printing, dipping, and brushing may be used.

  The fragrance seal 10 produced as described above is preferably stored in a laminate bag having a gas molecule barrier property, but may be a resin film bag, which is packaged in an airtight storage bag, Stored and distributed. If the fragrance seal 10 of this embodiment is an airtight storage bag for sustained release, a sufficient fragrance time after opening can be maintained.

  In the persistent fragrance of this embodiment, the essential oil, which is an aromatic component, is mixed with liquid paraffin in a solvent, and the essential oil mixed with the liquid paraffin is dispersed and held by a thickener to suppress volatilization and to provide sustained release. . Thereby, the fragrance of essential oil is stably maintained for a long time. In particular, when sodium carboxycellulose is used, colloidal particles containing essential oil are dispersed by being surrounded by sodium carboxycellulose due to its protective colloidal properties, and the essential oil components are uniformly dispersed in the medium and more effectively volatilize. Suppress and give sustained release. Thereby, the fragrance of essential oil is stably maintained for a long time.

  For example, in the case of the fragrance seal 10 formed by printing on a satin fabric 12, the fragrance is such that it cannot be perceived by human scent unless it approaches 50 cm, and is maintained for 2 weeks to 1 month. Moreover, the scent at the beginning of use is not too strong, and when worn on clothes or the like, the scent of passing through the scent lasts for a long time. Moreover, manufacture can be formed only by printing on the fabric 12, and can be manufactured easily.

  The long-lasting fragrance of the present invention can be used as a deodorant, an antibacterial agent, and the like, depending on the combination of the types of essential oil components and the mixture, in addition to the fragrance, and can be widely used. In addition, it removes pets, toilets, aging odors, etc., and spreads a good odor to the surroundings by mixing the persistent fragrance with essential oils and deodorants that have a deodorizing function and printing on the base material. Can do.

The manufacturing method of the fragrance seal of this invention is not limited to the said embodiment, The kind of essential oil can be selected suitably. The base material can be appropriately selected from other paper such as fabric, resin plate, metal plate, and the like.

  Next, an embodiment in which a long-lasting fragrance and a deodorant according to the present invention are combined will be described. The deodorant component used in this embodiment is not particularly limited, but a component having no re-emission and high safety is good, and a polymer adsorbent, particularly preferably a graft polymerization polymer adsorbent is good. Hereinafter, an embodiment using a graft polymerization polymer adsorbent will be described.

  First, the graft polymerization polymer adsorbent will be described. Graft polymerization polymer adsorbents have functional groups such as cationic polymer sulfonic acid groups, polymer carboxylic acid groups, amino groups, metal complexes, etc., so basic polar substances such as ammonia and amine substances, fatty acids It specifically adsorbs acidic polar substances such as mercaptan and hydrogen sulfide, and malodorous and harmful chemical substances such as aldehydes. In addition, since the graft polymer adsorbent does not adsorb substances other than these, there is no loss of adsorption capacity even when nonpolar substances coexist, and nonpolar substances can coexist as fragrances. In addition, the long-lasting fragrance and the aromatic seal of the present invention can have a function as a deodorizing sheet. The coexisting fragrance in this case is not particularly limited, but various terpene, ester, aromatic and other fragrances can be used.

  The persistent fragrance of the embodiment containing the graft polymerization polymer adsorbent can also be produced in the same manner as the above embodiment, and the thickener such as sodium carboxycellulose and the fixing agent for printing are mixed at the above-mentioned ratio. In this medium, 5 to 10% by mass of an essential oil that becomes an aromatic component, for example, an essential oil of rose, is mixed with this medium and a graft polymerization polymer adsorbent in an amount of 0.01 to 20% by mass of the medium. (Dry mass), preferably 0.02 to 10% by mass (dry mass), more preferably 0.05 to 5% by mass (dry mass) in an appropriate amount to prepare a persistent fragrance. .

  The graft polymer adsorbent of this embodiment is an adsorbing material composed of a substrate to which a macromonomer containing a functional group having the ability to adsorb polar substances is bonded, and the substrate used as the adsorbing material is not particularly limited. Any macromonomer can be used. For example, cellulose, polyolefin, polyacrylonitrile, polyester such as PET or PBT, polyamide such as nylon 6 or nylon 66, or the like can be used. The cellulose used as the substrate includes wood cellulose such as paper pulp and wood chip, and preferably paper pulp.

  Here, the macromonomer refers to a polymer having a polymerization degree intermediate between the polymerization degree of the oligomer and the polymerization degree of the polymer. The degree of polymerization of the macromonomer is preferably about 10 to about 100, more preferably about 50 to about 100. The macromonomer in this embodiment is preferably a polymerized reactive monomer containing a functional group capable of adsorbing polar substances, and has a degree of polymerization of about 10 to about 100.

The macromonomer includes a hydrophilic group and a cationic dissociative group, includes a hydrophilic group and an anionic dissociating group, or includes a hydrophilic group and a cation and an anionic dissociating group.

  In this embodiment, the hydrophilic group means a group that has an affinity for water and does not ionically dissociate when contacted with water. The hydrophilic group can capture water molecules present in the air. As a result, the trapped water molecules form an adsorbed water layer on the surface of the adsorbent material as the deodorant of the present invention, and polar substances are formed. It can dissolve and / or dissociate ionic substances. Hydrophilic groups include, for example, hydroxyl groups, hydroxyalkyl groups, preferably lower alkyl groups, and pyrrolidonyl groups. Preferred hydrophilic groups include a hydroxyl group and a hydroxyalkyl group.

  One or more hydrophilic groups may be introduced into the macromonomer, and examples of reactive monomers having such hydrophilic groups include hydroxyethyl methacrylate, hydroxypropyl acrylate, and vinylpyrrolidone. Dimethylacrylamide, ethylene glycol monomethacrylate, ethylene glycol monoacrylate, ethylene glycol diacrylate, ethylene glycol dimethacrylate, triethylene glycol diacrylate and triethylene glycol methacrylate. Among these, particularly useful reactive monomers include hydroxyethyl methacrylate and vinyl pyrrolidone.

  The cationic dissociation group is an ion exchange group whose counter ion is a cation, and a typical cationic dissociation group is an acid group. The cationic dissociation group has the ability to adsorb polar substances, and can release protons (hydrogen ions) to neutralize with basic substances such as ammonia and amines. As a result, the basic substance is removed. One or more kinds of cationic dissociation groups may be introduced into the macromonomer.

  Examples of the cationic dissociation group include a carboxyl group, a sulfone group, a phosphoric acid group, a sulfoethyl group, a phosphomethyl group, and a carbomethyl group. Preferred cationic dissociation groups include sulfone groups and carboxyl groups. Examples of useful reactive monomers having a cationic dissociation group include acrylic acid, methacrylic acid, styrene sulfonic acid and salts thereof, and 2-acrylamido-2-methylpropane sulfonic acid. A reactive monomer having a group that can be converted into a cationic dissociative group is also useful. Examples of such reactive monomers include glycidyl methacrylate and glycidyl acrylate.

  An anionic dissociating group is an ion exchange group in which the counter ion is an anion. The anionic dissociating group has an ability to adsorb polar substances and can neutralize with acidic substances such as hydrogen sulfide and mercaptans. As a result, acidic substances are removed. One or more anionic dissociation groups may be introduced into the macromonomer.

  Examples of the anionic dissociating group include a quaternary ammonium group and primary to tertiary amine groups such as an amino group, a methylamino group, a dimethylamino group, and a diethylamino group. Preferred anionic dissociation groups are quaternary ammonium groups and amino groups. Examples of useful reactive monomers having an anionic dissociating group include vinylbenzyltrimethylammonium salt, diethylaminoethyl methacrylate, dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, diethylaminoethyl acrylate, diethylaminomethyl methacrylate, and tertiary.

Further, another preferred combination of functional groups includes a sulfone group, a carboxyl group, a quaternary ammonium group, and a pyrrolidonyl group. The thus obtained macromonomer containing a functional group capable of adsorbing a polar substance can be used alone without being bound to the substrate. The macromonomer may be diluted and mixed with the persistent fragrance.

  The macromonomer is chemically bonded to the substrate, and a known method can be used as the bonding method. For example, a radiation graft polymerization method using a monosaccharide is preferably used.

  The adsorption mechanism of the deodorant component of the persistent fragrance in this embodiment is as follows. The macromonomer of the graft polymerization polymer adsorbent contains functional groups capable of adsorbing polar substances, particularly hydrophilic groups and cationic dissociation groups and / or anionic dissociation groups, and water present in the air by the hydrophilic groups. Molecules are attracted to the surface of the adsorbing material and adsorbed. In this way, an adsorbed water layer in which many water molecules are adsorbed is formed on the surface of the adsorbing material. The acidic or basic substance is trapped on the surface of the adsorbing material by interaction with a cation or an anionic dissociating group, and is also trapped on the surface of the adsorbing material by the action of adsorbed water. The substance thus captured dissociates into the adsorbed water layer and is neutralized by a cation or anionic dissociation group. General polar substances also dissolve in the adsorbed water layer due to their affinity with water.

  The adsorbing material, which is a deodorant contained in the persistent fragrance, has improved hydrophilicity and adsorbability of the substance to be adsorbed due to the presence of the cation and / or anionic dissociation group. Increase dissociation.

  The persistent fragrance of this embodiment is applied to bad breath, sweat odor, aging odor, excretion odor, etc. of humans, pets such as dogs, cats and birds, livestock such as cows, horses and pigs. By doing so, the odor is removed and a good fragrance is emitted. Furthermore, the present invention can be applied to deodorization of various odor-generating substances such as foods having a specific odor such as meat, fish and natto, cigarettes, garbage, refrigerators, odors in shoes and shoe boxes, and industrial wastewater.

Next, the deodorization test result using the persistent fragrance | flavor containing the deodorant component of this invention is demonstrated. In this example, the deodorizing performance of the graft polymer adsorbent was first tested. The deodorization test was conducted for ammonia and acetic acid in a constant temperature and humidity chamber at 20 ° C and 65% RH in accordance with the deodorant processed fiber product certification standard of the Japan Fiber Evaluation Technology Council. It carried out 3 times with the detection tube 14, and the reduction rate (%) of each odor component was computed by the following formula (1).
Reduction rate = [(average value of blank test−average value of measurement) / average value of blank test] × 100 (1)
(Average value: Average value of concentration (ppm) by gas detector tube)

In the test apparatus shown in FIG. 3, one sample 12 cut into a 10 cm square (100 cm ² ) was stored in an air bag 10 having a capacity of 5 L, and 3 L of dry air or nitrogen gas was put into the air bag 10. Next, the odorous substance gas is injected into the air bag 10 so that the set initial concentration (ammonia: 100 ppm, acetic acid: 50 ppm), and the test is started when the odorous substance gas is injected. Measurement was performed with a gas detector tube 14. The detection by the gas detection tube 14 was performed by sucking the gas in the airbag 10 through the suction tube 16.

  When a graft polymer adsorbent is used as the deodorant component, the ammonia concentration after 2 hours is 0.5 ppm or less, the decrease rate is 99% or more, and the acetic acid gas concentration after 2 hours is 1.1 ppm or less. The decrease rate was 95%.

  Further, as a result of conducting a deodorizing test in the same manner for the case of using a persistent fragrance (green tea and peppermint essential oil component) containing a graft polymer adsorbent which is a deodorant component of the present invention, 2 hours After that, the ammonia concentration was 1.0 ppm, the decrease rate was 99% or more, and the acetic acid gas concentration after 2 hours was 1.0 ppm or less, and the decrease rate was 95%.

Next, the deodorization test of nonenal and isovaleric acid was performed as an odor component. About nonenal and isovaleric acid, it changed into the gas detection tube, performed 3 times by the gas chromatography (GC) method, and the reduction rate (%) was computed by the following formula (2). First, in a 500 mL Erlenmeyer flask, put one sample cut to 50 cm ² and 3 L of odorless air, and the odorous substance gas so that the initial concentration set (nonenal: about 14 ppm, isovaleric acid: about 38 ppm). Was injected into the airbag 10. The test was started when the odorous substance gas was injected, and after 2 hours, the odorous substance concentration was collected with a gas tight syringe and injected into the GC to measure the gas concentration.
Reduction rate = [(Sb-Sb) / Sb] x 100 (2)
(Average of peak area of blank test = Sb, average of peak area of test sample = Sm)
(Peak area = amount of substance detected by GC)

  When a graft polymerization polymer adsorbent was used as the deodorant component, the decrease rate of isovaleric acid after 2 hours was 94%, and the decrease rate of nonenal after 2 hours was 96%. Similarly, as a result of performing a deodorization test by adding a scent, the decrease rate of isovaleric acid after 96 hours was 96%, and the decrease rate of nonenal after 2 hours was 95%.
