Description

[Technical Field]

[0001] The present disclosure relates to a fragrance for use in perfuming entrance or toilet wallpaper, which is used by volatilizing it in an entrance or toilet and can impart an excellent fragrance to the wallpaper in the entrance or toilet. [Background technology]

[0002] In recent years, approaches to improving living environments have been made from the perspective of fragrance, and various types of air fresheners have been developed. Conventionally, air fresheners are classified into two types: those that scent the air by volatilizing the fragrance and allowing it to waft throughout the space, and those that scent items such as wallpaper, floors, and textile products by attaching the fragrance to them. While the latter type mainly involves directly spraying the fragrance onto the item, in recent years, reports have been published of a type that can scent an item by volatilizing the fragrance in the air and then attaching it to the item. For example, Patent Document 1 describes that a wallpaper fragrance, which has a vapor pressure of 0.010 to 1.0 hPa at 25°C and is composed of one or more fragrance components with a cyclic structure, adheres to wallpaper upon volatilization and exhibits excellent fragrance release and long-lasting fragrance after attachment to the wallpaper.

[0003] The wallpaper fragrance described in Patent Document 1 is effective in making indoor spaces more comfortable, but there is an ever-increasing awareness of the need to further enrich living environments, and in order to meet consumer needs, there is a demand for the development of fragrances that can impart excellent fragrances to wallpaper. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-116587 Summary of the Invention [Problem to be solved by the invention]

[0005] Entryways and toilets are indoor spaces where odor control is particularly important. Because entryways and toilets have a smaller spatial volume than living rooms, not only are bad odors attached to the wallpaper easily perceived, but the scent of perfume attached to the wallpaper is also easily perceived. Therefore, applying a good fragrance to the wallpaper in entryways and toilets is an effective odor control measure.

[0006] Therefore, the present disclosure aims to provide a fragrance for wallpaper fragrance in an entrance or toilet that is used by volatilizing it in the entrance or toilet and that can impart an excellent fragrance to the wallpaper in the entrance or toilet. [Means for solving the problem]

[0007] The present inventors have conducted extensive research to solve the above-mentioned problems and have found that certain natural fragrances (lavender oil, lavandin oil, spearmint oil, ylang-ylang oil, lemongrass oil, peppermint oil, and lime oil) and certain fragrances with chain structures (hexyl acetate, ethyl butyrate, isoamyl acetate, and citral) are easily attached to wallpaper after volatilization, and the scent they give off after adhering to wallpaper is also pleasant, making them suitable as fragrances to be volatilized in entranceways or toilets where the smell of wallpaper is easily perceived. The present disclosure was completed through further research based on this finding.

[0008] That is, the present disclosure provides the inventions of the following aspects. Item 1. A fragrance for wallpaper fragrance in an entranceway or toilet, comprising at least one fragrance selected from the group consisting of lime oil, spearmint oil, peppermint oil, ethyl butyrate, isoamyl acetate, lavender oil, lavandin oil, ylang-ylang oil, lemongrass oil, hexyl acetate, and citral. Item 2. The flavoring is at least one selected from the group consisting of lime oil, spearmint oil, peppermint oil, ethyl butyrate, and isoamyl acetate; Item 1. The fragrance for wallpaper fragrance in the entrance or toilet according to Item 1, which is evaporated using an evaporator that evaporates through a membrane. Item 3. An air freshener composition for wallpaper fragrance in an entrance hall or a toilet, comprising the fragrance for wallpaper fragrance in an entrance hall or a toilet according to Item 1 or 2, and a solvent. Item 4. The air freshener composition for wallpaper fragrance in an entranceway or a toilet according to Item 3, a container body having an opening and containing the fragrance composition; a membrane covering the opening; A vaporizer used to scent wallpaper in an entrance hall or bathroom. Item 5. A method for scenting wallpaper in an entranceway or a toilet, comprising volatilizing at least one fragrance selected from the group consisting of lime oil, spearmint oil, peppermint oil, ethyl butyrate, isoamyl acetate, lavender oil, lavandin oil, ylang-ylang oil, lemongrass oil, hexyl acetate, and citral in the entranceway or toilet. [Effects of the Invention]

[0009] According to the present disclosure, an excellent fragrance can be imparted to the wallpaper in an entrance or toilet, so that the fragrance emitted from the wallpaper can scent the entrance or toilet, or can mask and deodorize bad odors adsorbed on the wallpaper, making the entrance or toilet a comfortable space. Conventionally, fragrances used in entrances or toilets can scent the air in an entrance or toilet, but they have difficulty adhering to the wallpaper, and therefore have been insufficient in terms of imparting a pleasant fragrance to the wallpaper or deodorizing bad odors adsorbed on the wallpaper. However, the present disclosure can overcome these drawbacks of the prior art. DETAILED DESCRIPTION OF THE INVENTION

[0010] 1. Fragrances for wallpaper in entranceways or toilets The fragrance of the present disclosure is a fragrance for wallpaper fragrance in an entranceway or a toilet, i.e., a fragrance used to scent the wallpaper in an entranceway or a toilet. Specifically, the fragrance of the present disclosure is characterized by comprising at least one selected from the group consisting of lime oil, spearmint oil, peppermint oil, ethyl butyrate, isoamyl acetate, lavender oil, lavandin oil, ylang-ylang oil, lemongrass oil, hexyl acetate, and citral. Lavender oil, lavandin oil, spearmint oil, ylang-ylang oil, lemongrass oil, peppermint oil, and lime oil are natural fragrances. Hexyl acetate, ethyl butyrate, isoamyl acetate, and citral are fragrances with a chain structure. By selecting at least one of these specific natural fragrances and fragrances with a specific chain structure and evaporating them in the entranceway or a toilet, an excellent fragrance can be imparted to the wallpaper in the entranceway or a toilet.

[0011] Lime oil is an essential oil obtained from the peel of limes (Citrus aurantifolia Swingle). Spearmint oil is an essential oil obtained from the whole plant or aerial parts of Mentha spicata. Peppermint oil is an essential oil obtained from the whole plant or aerial parts of Mentha piperita. Ethyl butyrate is a chain carboxylic acid ester formed by the condensation of acetic acid and ethanol. Isoamyl acetate is a chain carboxylic acid ester formed by the condensation of acetic acid and isoamyl alcohol. Lavender oil is an essential oil obtained from the flowers or flower stems of lavender (Lavandula officinalis L.). Lavandin oil is an essential oil obtained from the flower spikes of lavandin. Ylang-ylang oil is an essential oil obtained from the flowers of ylang-ylang (Cananga odorata). Lemongrass oil is an essential oil obtained from the leaves, whole plant, or aerial parts of lemongrass (Cymbopogon citrarus, Cymbopogon schoenanthus). Hexyl acetate is a chain carboxylic acid ester formed by condensation of acetic acid and hexyl alcohol. Citral is a chain monoterpene aldehyde, including geranial (α-citral) and neral (β-citral).

[0012] The above-mentioned fragrances may be used alone or in combination of two or more.

[0013] Of these fragrances, from the viewpoint of further improving adhesion to wallpaper and the pleasantness of the scent emitted from the wallpaper after adhesion, preferred are lavender oil, lavandin oil, lemongrass oil, lime oil, hexyl acetate, and citral, more preferred are lavender oil, lime oil, and hexyl acetate, and even more preferred are lavender oil and lime oil.

[0014] When the fragrance of the present disclosure is evaporated using a vaporizer that vaporizes the fragrance through a membrane, from the viewpoint of achieving a favorable combination of adhesion to wallpaper, the pleasantness of the scent emitted from the wallpaper after adhesion, and the vaporization of the fragrance from the vaporizer, among the fragrances, preferred are spearmint oil, peppermint oil, lime oil, ethyl butyrate, and isoamyl acetate, and more preferably lime oil.

[0015] The fragrance of the present disclosure is used by being vaporized in an entranceway or a toilet. When the fragrance of the present disclosure is vaporized in an entranceway or a toilet, it adheres to the wallpaper of the entranceway or the toilet, imparting a pleasant fragrance to the wallpaper and making the entranceway or the toilet a comfortable space. The fragrance of the present disclosure may be vaporized alone in an entranceway or a toilet, but it is preferably blended into an air freshener composition described below and vaporized in the entranceway or the toilet.

[0016] The surface material of the wallpaper used in the entrance hall or toilet to which the fragrance of the present disclosure is applied is not particularly limited, and may be any resin such as polyvinyl chloride, polyolefin, polyester, etc. A suitable example of an application of the fragrance for the entrance hall or toilet of the present disclosure is an entrance hall or toilet having wallpaper whose outermost layer is a polyvinyl chloride layer.

[0017] 2. Air freshener composition for wallpaper fragrance in entrance halls or toilets The air freshener composition of the present disclosure is an air freshener composition for wallpaper fragrance in an entranceway or a toilet, i.e., an air freshener composition for use in an entranceway or a toilet to scent the wallpaper in the entranceway or the toilet. Specifically, the air freshener composition of the present disclosure is characterized by comprising a fragrance for wallpaper fragrance in an entranceway or a toilet, and a solvent.

[0018] In the fragrance composition of the present disclosure, the content of the fragrance is not particularly limited, but may be, for example, 0.05% by weight or more, preferably 0.05% by weight to 50% by weight, more preferably 0.1% by weight to 30% by weight, and even more preferably 0.5% by weight to 15% by weight.

[0019] The type of solvent contained in the aromatic composition of the present disclosure is not particularly limited, but examples thereof include water, paraffinic hydrocarbons (plasma fluid isoparaffin, plasma fluid normal paraffin), 3-methoxy-3-methyl-1-butanol, propylene glycol monomethyl ether, etc. These solvents may be used alone or in combination of two or more.

[0020] In the fragrance composition of the present disclosure, the content of the solvent is not particularly limited, but may be, for example, 45% by weight or more and 99.95% by weight or less, preferably 65% ​​by weight or more and 99.9% by weight or less, and more preferably 80% by weight or more and 99.5% by weight or less.

[0021] The air freshener composition for entrance halls or toilets of the present disclosure may contain fragrances other than the fragrances for perfumery of the wallpaper for entrance halls or toilets, if necessary.

[0022] The fragrance composition of the present disclosure may further contain other additives, as long as the effects of the present disclosure are not impaired. Examples of additives that can be incorporated into the fragrance composition of the present disclosure include surfactants, preservatives, antioxidants, pH adjusters, deodorizers, disinfectants, UV absorbers, insecticidal components, insect repellent components, repellent components, organic foaming agents, binders, etc.

[0023] The form of the fragrance composition of the present disclosure is not particularly limited as long as the fragrance can be evaporated, but examples thereof include liquid and gel forms. Liquid forms are preferred.

[0024] The volatilizer for volatilizing the fragrance composition of the present disclosure is not particularly limited, but a suitable example is a volatilizer that volatilizes through a membrane. The volatilizer includes the fragrance composition of the present disclosure, a container body with an opening, and a membrane. In the volatilizer, for example, the fragrance composition of the present disclosure is contained in a container body, and the opening of the container body is covered with a membrane. The membrane may be permeable to at least one of gas and liquid. Membranes used in volatilizers are known in the art, and examples include gas-permeable membranes and gas- and liquid-permeable membranes. The gas-permeable membrane may be a film having pores that allow gas to pass through but not liquid to pass through, specifically a porous film made of polyethylene (such as low-density polyethylene). The gas- and liquid-permeable membrane may be a film that allows gas to pass through but is permeable enough to prevent liquid from spilling out, specifically a porous film made of polyolefin such as polyethylene or polypropylene and silica. Porous films formed from polyolefins such as polyethylene or polypropylene and silica have the property of being difficult to permeate highly polar liquids such as water, but easily permeable to oil-based liquids.

[0025] A volatilizer that volatilizes through a membrane can volatilize the aromatic composition while preventing spillage of the aromatic composition. However, when using a volatilizer that volatilizes through a membrane, it is desirable to select a fragrance that easily permeates the membrane when blended into the aromatic composition. For example, when at least one selected from the group consisting of spearmint oil, peppermint oil, lime oil, ethyl butyrate, and isoamyl acetate is used, using a volatilizer that volatilizes through a membrane can prevent spillage of the aromatic composition and can impart an excellent fragrance to the wallpaper in the entrance or bathroom through the membrane. In entrances or bathrooms, where the spatial volume is small compared to the living room, it is expected that the volatilizer will fall over due to contact with the user's hand, etc., but the volatilizer can impart an excellent fragrance while preventing spillage of the aromatic composition, thereby further improving user comfort.

[0026] Other examples of volatilizers for volatilizing the aromatic composition of the present disclosure include volatilizers that volatilize the aromatic composition of the present disclosure through a volatilization member such as a nonwoven fabric, a wooden material, or a sponge. Specifically, a volatilizer includes a liquid container with an opening, a volatilization member, and the aromatic composition of the present disclosure contained in the liquid container. For example, at least a portion of the volatilization member is immersed in the aromatic composition of the present disclosure and can be exposed to air through the opening. The material of the volatilization member is not particularly limited as long as it has the properties to be impregnated with the aromatic composition of the present disclosure and volatilize it. Examples include natural fibers such as cotton, plant fibers, and pulp; synthetic fibers such as polyester; wooden materials such as rattan; and resin sponge materials such as urethane foam. When the volatilization member is made of a fibrous material, it is preferably filter paper or nonwoven fabric, but may also be woven or knitted. The shape of the volatilization member is not particularly limited and may be any of a sheet, block, rod, strip, string, etc.

[0027] 3. How to scent the wallpaper in the entrance or bathroom The fragrance application method of the present disclosure is a method for applying fragrance to wallpaper in an entranceway or a toilet, and is characterized in that at least one fragrance selected from the group consisting of lime oil, spearmint oil, peppermint oil, ethyl butyrate, isoamyl acetate, lavender oil, lavandin oil, ylang-ylang oil, lemongrass oil, hexyl acetate, and citral is vaporized in the entranceway or toilet. The fragrances used in the fragrance application method of the present disclosure are as described above. [Example]

[0028] Examples will be described below, but the present disclosure is not limited to these examples.

[0029] Test Example 1 Wallpaper (sticker-type wallpaper option: pattern: SW-34 frisch, outermost layer is polyvinyl chloride layer, manufactured by Asahipen Co., Ltd.) was cut into 5 cm x 5 cm squares. The cut wallpaper was placed in a glass bottle (bottom area 28.3 cm).2 The wallpaper was attached to the inside wall of a glass bottle (11 cm high) at a height of 6 cm from the bottom, with the surface facing outward. A cotton ball (approximately 14 mm in diameter) was impregnated with 20 μl of the fragrances shown in Tables 1 to 4 and placed at the bottom of the glass bottle prepared above. The bottle was then sealed with a lid and left to stand overnight. The wallpaper was then removed from the glass bottle and subjected to a sensory evaluation of the fragrance intensity and pleasantness / unpleasantness of the fragrance using a 9-point pleasantness / unpleasantness rating system and a 6-point odor intensity rating system. The sensory evaluation was performed by eight or nine trained individuals, and an average score was calculated for each evaluation item. The evaluation criteria for the 9-point pleasantness / unpleasantness rating system and the 6-point odor intensity rating system are shown below. <9-level comfort / discomfort rating system (evaluation criteria for comfort / discomfort)> +4: Extremely comfortable +3: Very comfortable +2: pleasure +1: Somewhat comfortable 0: Neither pleasant nor unpleasant -1: Slightly uncomfortable -2: Unpleasant -3: Very uncomfortable -5: Extremely uncomfortable <6-level odor intensity rating system (fragrance intensity evaluation criteria)> 0: Odorless 1: Scent that can barely be detected (detection threshold) 2: A weak scent that can be identified (recognition threshold) 3: Easily detectable scent 4: Strong fragrance 5: Strong fragrance

[0030] In Tables 1 to 4, "10% DPG" refers to a fragrance liquid containing fragrance ingredients at a concentration of 10% by weight in dipropylene glycol, "1% DPG" refers to a fragrance liquid containing fragrance ingredients at a concentration of 1% by weight in dipropylene glycol, "50% BB" refers to a fragrance liquid containing fragrance ingredients at a concentration of 50% by weight in benzyl benzoate, "10% BB" refers to a fragrance liquid containing fragrance ingredients at a concentration of 10% by weight in benzyl benzoate, and "10% TEC" refers to a fragrance liquid containing fragrance ingredients at a concentration of 10% by weight in triethyl citrate. The same applies to Table 5.

[0031] The results are shown in Tables 1 to 4. As a result, when lavender oil, lavandin oil, spearmint oil, ylang-ylang oil, lemongrass oil, peppermint oil, lime oil, hexyl acetate, ethyl butyrate, isoamyl acetate, and citral were used, the average score was high at 4 or above according to the 6-point odor intensity rating system, indicating that these fragrances have the property of easily adhering to wallpaper after volatilization. Moreover, these fragrances had an average score of 0 or above according to the 9-point pleasantness / unpleasantness rating system, confirming that the scent they emitted after adhering to wallpaper was also pleasant. On the other hand, the fragrances of Comparative Examples 1 to 97 did not achieve an average score of 4 or above according to the 6-point odor intensity rating system or an average score of 0 or above according to the 9-point pleasantness / unpleasantness rating system.

[0032] These results demonstrate that when lavender oil, lavandin oil, spearmint oil, ylang-ylang oil, lemongrass oil, peppermint oil, lime oil, hexyl acetate, ethyl butyrate, isoamyl acetate, and citral are placed in an entrance hall or toilet and allowed to volatilize, they adhere to the wallpaper in the entrance hall or toilet, and can scent the wallpaper.

[0033] [Table 1]

[0034] [Table 2]

[0035] [Table 3]

[0036] [Table 4]

[0037] Test Example 2 6 ml of the fragrance shown in Table 5 was placed in a container with an opening of 6.8 ml capacity (opening area 17.3 cm2 ) and covering and sealing the opening with a membrane permeable to at least one of gas and liquid, to prepare a volatilizer. The membranes used were membrane A (a porous membrane made of low-density polyethylene) and membrane B (a porous membrane formed of polyethylene and silica). The volatilizer was placed in a stainless steel sensory box (1000 L), which was then sealed and left to stand for 15 minutes. Thereafter, the intensity of the fragrance in the sensory box was subjected to a sensory evaluation using a 6-level odor intensity rating method. The evaluation criteria for the 6-level odor intensity rating method are as shown in Test Example 1 above. The sensory evaluation was performed by 8 or 9 trained individuals, and the average score for fragrance intensity was calculated.

[0038] The results are shown in Table 5. As a result, when spearmint oil, peppermint oil, lime oil, ethyl butyrate, and isoamyl acetate were used, the fragrance intensity was 4.0 or higher, and it was found that gases easily volatilized through the permeable membrane.
