Description

[Technical field]

[0001] The present invention relates to an aromatic composition that contains a fragrance and a polyphenol and yet is capable of suppressing discoloration that occurs over time. [Background technology]

[0002] Air freshener compositions containing fragrances are widely used to disperse fragrances in rooms and create comfortable spaces. In order to diversify the functionality of air freshener compositions, air freshener compositions that combine both air freshener and deodorizing functions by blending deodorizing ingredients together with the fragrances have been developed (see, for example, Patent Document 1).

[0003] Polyphenols such as green tea catechins and persimmon tannins have been known to have excellent deodorizing effects, and attempts have been made to incorporate them into fragrance compositions. However, when polyphenols are incorporated into a fragrance composition, there is a problem that the fragrance composition discolors over time and cannot maintain a good appearance. In particular, when the fragrance composition contained in a container is absorbed into a volatilizing member and then volatilized, there is a problem that discoloration due to polyphenols becomes noticeable at the part of the volatilizing member that comes into contact with air, resulting in a significant deterioration in appearance.

[0004] As described above, polyphenol-containing fragrance compositions have a particular problem of discoloration over time, but to date, there has been no sufficient research into techniques for suppressing the discoloration and maintaining a good appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] 1.Fragrance composition The aromatic composition of the present invention is characterized by containing a fragrance, a polyphenol, and a pigment. The aromatic composition of the present invention will be described in detail below.

[0011] [Fragrance] The fragrance composition of the present invention contains a fragrance as a fragrance component. The fragrance used in the present invention may be any oil-based fragrance such as a natural fragrance, a single fragrance separated from a natural fragrance, a synthetic single fragrance, or a blend of these fragrances, and a conventionally known fragrance may be used. Specifically, examples of the single fragrance include hydrocarbon-based fragrances, alcohol-based fragrances, ether-based fragrances, aldehyde-based fragrances, acetal-based fragrances, ester-based fragrances, ketone-based fragrances, carboxylic acid-based fragrances, lactone-based fragrances, musk-based fragrances, nitrile-based fragrances, and sulfur-containing fragrances. Natural fragrances include tuberose oil, musk tincture, castoreum tincture, civet tincture, ambergris tincture, peppermint oil, perilla oil, petitgrain oil, pine oil, rose oil, rosemary oil, camphor oil, aromatic oils, clary sage oil, sandalwood oil, spearmint oil, spike lavender oil, star anise oil, lavandin oil, lavender oil, lemon oil, lemongrass oil, lime oil, neroli oil, oakmoss oil, ocotia oil, patchouli oil, and thyme oil. , tonka bean tincture, turpentine oil, crocodile bean tincture, basil oil, nutmeg oil, citronella oil, clove oil, boreal rose oil, cananga oil, cardamom oil, cassia oil, cedarwood oil, orange oil, mandarin oil, tangerine oil, anise oil, bay oil, coriander oil, elemi oil, eucalyptus oil, fennel oil, galbanum oil, geranium oil, hiba oil, cypress oil, jasmine oil, vetiver oil, bergamot oil, ylang-ylang oil, grapefruit oil, yuzu oil, etc. These fragrances may be used alone or in any combination of two or more.

[0012] The content of the fragrance in the fragrance composition of the present invention may be appropriately set depending on the type of fragrance used, the strength of the fragrance to be imparted, etc., and may be, for example, 0.1 to 30% by weight, preferably 0.5 to 10% by weight, and more preferably 1 to 5% by weight.

[0013] [Polyphenols] The aromatic composition of the present invention contains a polyphenol. In conventional aromatic compositions, the inclusion of a polyphenol causes discoloration over time, which leads to a problem of deterioration in appearance. However, the present invention contains a pigment described below, which makes it possible to suppress discoloration over time and maintain good appearance.

[0014] The type of polyphenol used in the present invention may be appropriately selected according to the functionality to be imparted to the fragrance composition, and a suitable example is a polyphenol that can function as a deodorizing component.Specific examples of polyphenols that can function as deodorizing components include flavonoids such as tannin, catechin, anthocyanin, rutin, and flavone; phenolic acids such as ellagic acid and coumarin, etc.Among these polyphenols, flavonoids are preferred, and tannin and catechin are more preferred.

[0015] The origin of these polyphenols is not particularly limited and may be appropriately determined depending on the type of polyphenol used, but suitable examples include tannins derived from persimmons (persimmon tannins) and catechins derived from green tea (green tea catechins). Persimmon tannins and green tea catechins have excellent deodorizing properties, but in the prior art, when they are added to an aromatic composition, there is a problem that they cause significant browning over time. However, the aromatic composition of the present invention can effectively suppress browning even when it contains persimmon tannins and / or green tea catechins.

[0016] In the present invention, a plant extract containing polyphenol may be used as the polyphenol. The plant extract containing polyphenol may be one obtained by extracting a plant containing polyphenol, or a commercially available product.

[0039] [Form / Application] The form of the aromatic composition of the present invention is not particularly limited, and may be, for example, liquid or gel. The aromatic composition of the present invention is preferably in the form of a liquid. The aromatic composition of the present invention is used as an aromatic for a room, a toilet, a car, etc.

[0040] [Volatilization materials] The method of volatilizing the aromatic composition of the present invention is not particularly limited, but a suitable example is a method of absorbing the aromatic composition into a volatilizing member and volatilizing it. An example of a volatilizer equipped with a volatilizing member is a volatilizer that includes a container having an opening, a volatilizing member, and the aromatic composition of the present invention contained in the container, at least a part of the volatilizing member is immersed in the aromatic composition of the present invention, and at least a part of the volatilizing member is installed so that it can be exposed to the air from the opening. By using such a volatilizer, the volatilizing member absorbs and volatilizes the liquid aromatic composition of the present invention, and the aroma can be efficiently volatilized into the space.

[0041] The material of the volatilization member is not particularly limited as long as it has the property of being impregnated with the aromatic composition and volatilizing it, and examples thereof include fibrous materials such as natural fibers such as cotton, vegetable fibers, and pulp, synthetic fibers such as rayon, polyester, and polyethylene terephthalate, and mixtures thereof; wood materials such as wood chips, rattan, bamboo, and sora; and resin sponge materials such as urethane foam.

The shape of the volatilization member is not particularly limited, and it may be any of a sheet, block, rod, strip, string, etc.

[0042] In the prior art, when a polyphenol-containing aromatic composition is volatilized using a volatilization member made of a fibrous material, there is a problem that discoloration due to polyphenol becomes prominent at the portion of the volatilization member that is in contact with air, resulting in a significant deterioration in appearance, but the aromatic composition of the present invention overcomes such a problem, and even if a volatilization member made of a fibrous material is used, discoloration of the volatilization member can be effectively suppressed. In view of such special effects of the present invention, one preferred embodiment of the aromatic composition of the present invention is volatilization using a volatilization member made of a fibrous material.

[0043] 2. How to prevent discoloration The method for inhibiting discoloration of the present invention is a method for inhibiting discoloration of an aromatic composition containing a fragrance and a polyphenol, and is characterized in that the aromatic composition contains a fragrance, a polyphenol, and a pigment.

[0044] In the discoloration suppression method of the present invention, the types and contents of the fragrances, polyphenols, pigments, and other ingredients blended into the fragrance composition, the form and use of the fragrance composition, the volatile materials used, etc. are as described in the section "1. Fragrance composition" above. EXAMPLES

[0045] The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

[0046] Test Example 1 A liquid fragrance composition having the composition shown in Table 1 was prepared. 400 ml of the obtained fragrance composition was placed in a 450 ml container (area of ​​opening: approximately 7 cm 2 ) and place it in a volatile material (polyethylene A nonwoven composite fiber material of ethylene terephthalate and pulp (a nonwoven sheet of 295 mm in length, 39 mm in width, and 6 mm in thickness, folded and layered starting from the center in the length direction) was inserted into the container, and the volatile component was arranged so that a part of the volatile component was exposed outside the opening of the container, and the container was impregnated with the aromatic composition. In this state, the container was stored for one month in a room exposed to sunlight.

[0047] Five panelists trained in color tone evaluation observed the difference in color tone of the fragrance composition at the start of storage and after one month of storage, and the difference in color tone of the part of the volatilizing component in contact with air at the start of storage and after one month of storage, and scored the results as 0, 1, 2, 3, 4, 3, or 5 points, with "5 points" indicating no change in color tone at all between the start of storage and after one month of storage, and "0 points" indicating a significant change in color tone between before and after one month of storage. The scores of the five panelists were added up and the color stability was evaluated according to the following classification criteria. <Classification criteria for color stability> ◎: Total score is between 41 and 50 points ○: Total score is between 31 and 40 points △: Total score is 21-30 points ×: The total score is 0 to 20 points.

[0048] The results are shown in Table 1. When an aromatic composition containing no pigment but a fragrance and polyphenol was used, discoloration (browning) of the aromatic composition was observed after storage, and discoloration of the volatile component was particularly noticeable after storage (Comparative Examples 1 and 2). In contrast, when an aromatic composition containing a pigment together with a fragrance and polyphenol was used, discoloration of the aromatic composition and the volatile component could be effectively suppressed even after storage (Examples 1 to 14). In particular, as can be seen from a comparison between Examples 1 and 3 and Examples 2 and 4 to 9, when CI Pigment Blue-15, a phthalocyanine blue pigment, and Pigment Green-7, a phthalocyanine green pigment, were used, discoloration of both the aromatic composition and the volatile component after storage was significantly suppressed.
