Description

[Technical Field]

[0001] The present invention relates to a deodorant fragrance composition. [Background technology]

[0002] Due to diversification of consumer preferences and living environments, the number of people who are sensitive to odors and body odors around them is increasing, and deodorant compositions that correspond to the types of odors have been proposed.

[0003] For example, it has been reported that a deodorizing and stain-resistant agent containing one or more surfactants selected from anionic surfactants and amphoteric surfactants, and an amine oxide surfactant or a thickener, and having the pH adjusted to within a specific range using a substance with buffering capacity, can block bad odors emanating from sources such as feces and effectively prevent bad odors (Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-336337 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, natural disasters such as typhoons, heavy rains, earthquakes, and fires have occurred frequently, forcing disaster victims to live in evacuation shelters. Evacuation shelters often require sharing a single space without walls or partitions with many other people, sharing temporary toilets, not bathing, and consuming instant foods such as cup noodles as emergency food. As a result, evacuation shelters are filled with a variety of odors, including feces and urine odors from temporary toilets, body odor due to the inability to bathe, and food odors from instant foods such as cup noodles, and in some places, these odors are mixed together. Because these odors contribute to the stress of disaster victims living in evacuation shelters, there is a need for a composition that can deodorize all of the feces and urine odors, body odor, and food odors.

[0006] However, the present inventors have confirmed that the above-mentioned conventional compositions have the following problem. That is, when the above-mentioned conventional compositions are applied to a place where various odors are mixed, such as an evacuation shelter, it is necessary to blend a high concentration of fragrance components, and the high concentration generates a chemical odor, which causes discomfort. Here, in this specification, "chemical odor" refers to an unpleasant odor that is chemical and artificial and causes discomfort, and specifically refers to a greasy, fishy odor. Therefore, an object of the present invention is to provide a deodorizing fragrance composition that can deodorize all of feces and urine odors, food odors, and body odors without producing chemical odors. [Means for solving the problem]

[0007] The inventors have conducted various studies in light of the above-mentioned problems and have found that by combining specific fragrance components and controlling the mass ratio of the two, it is possible to deodorize all of the odors of feces and urine, food, and body odor without causing discomfort due to chemical odors, even when the components are highly concentrated.

[0008] That is, the present invention provides the following [1] to

[0009] According to the present invention, it is possible to provide a deodorizing fragrance composition that can deodorize all of feces and urine odors, food odors, and body odors without generating chemical odors. DETAILED DESCRIPTION OF THE INVENTION

[0010] [Deodorizing fragrance composition] The deodorant fragrance composition of the present invention contains component (A) and component (B) in a specific mass ratio. The human nasal cavity contains approximately 400 olfactory receptors. Each olfactory receptor is activated by recognizing a specific odorant as an agonist, stimulating the olfactory nerve and transmitting odor information to the brain. However, odors distinct from the specific odors recognized by the agonist may also activate olfactory receptors. Specifically, the deodorizing fragrance composition of the present invention has a completely different scent from feces and urine odors, food odors, and body odors (hereinafter also referred to as "target malodors"). By acclimatizing the olfactory receptors that respond to the "target malodors" to the scent of the deodorizing fragrance composition of the present invention, the olfactory sensitivity to the "target malodors" is reduced or altered, thereby inducing "odor cross-adaptation." Thus, the deodorizing fragrance composition of the present invention contains component (A) and component (B) in a specific quantitative ratio, thereby reducing or altering the odor intensity of the "target malodor" as perceived by humans based on "odor cross-adaptation," thereby suppressing responses to the "target malodor." Therefore, the mechanism of action of the deodorizing fragrance composition of the present invention is completely different from that of conventional masking methods that conceal "target malodors" with fragrance components that emit strong odors.

[0011] Here, in this specification, "fecal odor" refers to the odor of human feces or urine, and examples of causative substances include cyclic nitrogen-containing compounds such as skatole and indole, phenols such as p-cresol, lower fatty acids such as butyric acid and isovaleric acid, other thiol compounds, and mixtures of sulfide compounds and nitrogen compounds. Furthermore, "body odor" refers to the odor emitted from the human body or worn clothing, and examples of causative substances include saturated aldehydes such as octanal and nonanal, unsaturated aldehydes such as nonenal, lower fatty acids such as isovaleric acid and butyric acid, and other lactones. Furthermore, "food odor" refers to the odor emitted from cooked instant foods, such as the odor emitted from cooked instant noodles, and examples of causative substances include diacetyl and isovaleraldehyde.

From the above viewpoint and from the viewpoint of economy of heating the solvent, the temperature is preferably 60° C. or lower, more preferably 50° C. or lower, and even more preferably 40° C. or lower.

[0057] <Application of deodorant fragrance composition> The deodorizing fragrance composition of the present invention exerts a deodorizing effect against one or more of feces and urine odor, body odor, and food odor through "odor cross-adaptation," and is therefore applied to a subject before the subject is exposed to one or more of the target odors, which are feces and urine odor, body odor, and food odor. The timing of application of the deodorizing fragrance composition of the present invention is not particularly limited as long as it is before exposure to the target malodor, but from the viewpoint of exerting a high deodorizing effect, it is preferably applied 5 seconds or more before exposure to the target malodor, more preferably 10 seconds or more before, even more preferably 60 seconds or more before, even more preferably 120 seconds or more before, and especially preferably 150 seconds or more before. Furthermore, from the viewpoint of suppressing discomfort caused by continuous exposure to the fragrance and preventing a decrease in deodorizing effect due to the evaporation of the fragrance, it is applied preferably up to 12 hours, more preferably up to 6 hours, even more preferably up to 3 hours, still more preferably up to 1 hour, even more preferably up to 30 minutes before, and especially preferably up to 10 minutes before exposure to the target malodor. That is, the timing of application of such a deodorizing fragrance composition is preferably from 5 seconds to 12 hours before exposure to the target malodor, more preferably from 10 seconds to 6 hours before, even more preferably from 60 seconds to 3 hours before, even more preferably from 60 seconds to 1 hour before, even more preferably from 120 seconds to 1 hour before, especially preferably from 120 seconds to 30 minutes before, and especially preferably from 150 seconds to 10 minutes before.

[0058] The application time of the deodorizing fragrance composition of the present invention to a subject before exposure to any one or more of feces and urine odor, body odor, and food odor is preferably 5 seconds or more, more preferably 10 seconds or more, even more preferably 60 seconds or more, even more preferably 120 seconds or more, and especially preferably 150 seconds or more, from the viewpoint of highly exerting the deodorizing effect. Furthermore, from the viewpoint of suppressing discomfort caused by continuous exposure to the fragrance and preventing a decrease in the deodorizing effect due to the evaporation of the fragrance, the application time of the deodorizing fragrance is preferably 12 hours or less, more preferably 6 hours or less, even more preferably 3 hours or less, even more preferably 1 hour or less, especially preferably 30 minutes or less, and especially preferably 10 minutes or less. That is, the application time of such a deodorant fragrance composition is preferably from 5 seconds to 12 hours, more preferably from 10 seconds to 6 hours, even more preferably from 60 seconds to 3 hours, even more preferably from 60 seconds to 1 hour, especially preferably from 120 seconds to 30 minutes, and even more especially preferably from 150 seconds to 10 minutes.

[0059] The application method is not particularly limited as long as the deodorizing fragrance composition is applied to a subject before exposure to the target malodor. Note that, as long as the deodorizing fragrance composition is applied before exposure to the target malodor, the application of the deodorizing fragrance composition may be stopped or continued during exposure to the target malodor. In particular, in terms of making it easier to enjoy the effects of the present invention, it is preferable to apply the deodorizing fragrance composition before exposure to the target malodor and continue applying it during exposure to the target malodor.

[0060] The application method can be set appropriately depending on the usage mode, but the usage mode described above will be explained as an example. For example, in the case of the above-mentioned embodiment (1), another article may be impregnated with the deodorizing fragrance composition of the present invention as is, and the impregnated article may be applied to a subject before exposure to the target malodor. Specific examples of such products include a sticker (fragrance-impregnated sticker) impregnated with the deodorizing fragrance composition of the present invention, and a mask (fragrance-impregnated mask) impregnated with the deodorizing fragrance composition of the present invention. The fragrance-impregnated mask may also be a mask to which a fragrance-impregnated sticker has been attached. For example, a subject may wear the fragrance-impregnated mask before exposure to the target malodor, and continue to wear it while exposed to the target malodor. In the case of the above-mentioned embodiment (2), the deodorizing fragrance composition of the present invention may be mixed with other components and used. Specific examples of such products include deodorizers (Table 10), toilet cleaners (Table 11), floor cleaners, fabric softeners, and laundry detergents. In the case of deodorizers, for example, by spraying the composition on curtains or the like in a care facility or the like in advance, the deodorizing fragrance composition can reach the nose of the care recipient by the time the care recipient enters the room for a diaper change or the like and approaches the care recipient, thereby eliminating odors present when the care recipient's diaper is changed. Furthermore, in the case of toilet cleaners or floor cleaners, the composition can be sprayed on the toilet bowl or floor before the care recipient enters the room or before the care recipient defecates, so that the deodorizing fragrance composition can reach the nose of the care recipient when the care recipient enters the room. Furthermore, in the case of a laundry detergent or a laundry softener, for example, when a subject wears washed clothes, the scent remaining on the clothes can allow the deodorizing fragrance composition to reach the user's nose. Among these, the embodiment (1) is preferred, with a fragrance-impregnated sticker and a fragrance-impregnated mask being more preferred, a fragrance-impregnated sticker being even more preferred, and a fragrance-impregnated mask with a fragrance-impregnated sticker attached being even more preferred.

[0064] <Sensory evaluation> Using the deodorizing fragrance compositions obtained in each Example and Comparative Example, fragrance-impregnated stickers were prepared by the following method. Next, fragrance-impregnated masks were prepared by the following method using the fragrance-impregnated sheets. The fragrance-impregnated masks were then subjected to the following evaluations.

[0065] (Preparation of fragrance-impregnated stickers) 0.05 g of the deodorant fragrance composition obtained in each Example and Comparative Example was dropped onto a sticker (Pitatto Aroma Stick-on Aroma Sticker, Unscented, manufactured by Aglaia Clinical Aromatic Lab, diameter approximately 3 cm, mass 0.2 g / sticker) using a micropipette, and left to stand for 30 minutes under conditions of 25°C and 45% RH to allow the deodorant fragrance composition to permeate the entire sticker, yielding a fragrance-impregnated sticker.

[0066] (Preparation of fragrance-impregnated mask) A fragrance-impregnated sticker was attached to the center of a nonwoven fabric mask (super-three-dimensional mask, regular size, manufactured by Unicharm Corporation, mass 2.2 g / piece) to create a fragrance-impregnated mask.

[0067] (Evaluation method) A sensory test was conducted by a panel of five experts who agreed to evaluate the deodorizing effects on feces and urine odor, body odor, and food odor according to the following procedures and criteria.

[0068] 1. Evaluation of feces and urine odor (1) Each component was mixed in the proportions shown in Table 2 to prepare a model feces and urine odor.

[0069] [Table 2]

[0070] (2) The model feces and urine odor was further diluted to 10% with dipropylene glycol, and 1 μL of the solution was impregnated into a 14 mm diameter cotton ball (#14, Kawamoto Sangyo Co., Ltd.) using a micropipette. The impregnated cotton ball was placed in a standard bottle (No. 11, 110 mL, Hakuyo Glass Co., Ltd.), the lid was placed on the bottle, and the bottle was left to stand for 30 minutes under conditions of 25°C and 45% RH for evaluation. (3) The participants wore a nonwoven mask (Super 3D Mask, regular size, manufactured by Unicharm Corporation, weight 2.2 g / piece) without a fragrance-impregnated sticker, opened the lid of the bottle described in (2) above, smelled it, and recorded the odor intensity at that time as the “odor intensity before wearing the mask.” (4) The fragrance-impregnated mask was worn for 3 minutes under conditions of 25°C and 45% RH. (5) After 3 minutes had passed, the subjects, while wearing the fragrance-impregnated mask, opened the lid of the bottle (2) above and smelled the odor, and recorded the odor intensity as the "odor intensity after wearing the mask." (6) The intensity of the malodor after wearing the mask was evaluated according to the following criteria, and the average scores of five expert panelists are shown in each table.
