Description

The present invention relates to a deodorizing fragrance composition.

Due to diversifying consumer preferences and living environments, an increasing number of people are becoming sensitive to odors and body odors around them, and deodorant compositions tailored to different types of odors have been proposed.

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 whose pH is adjusted to within a specific range using a substance with buffering capacity, can block malodors emanating from sources such as feces, effectively preventing malodors (Patent Document 1).

Japanese Patent Application Laid-Open No. 2002-336337

In recent years, natural disasters such as typhoons, heavy rains, earthquakes, and fires have become more frequent, sometimes forcing victims to take refuge in evacuation centers. Evacuation centers often require sharing a single space with many others, without walls or partitions, while also sharing temporary toilets. They often skip bathing and rely on instant foods such as cup noodles as emergency food. As a result, evacuation centers are filled with a variety of unpleasant odors, including the smell of feces and urine from temporary toilets, body odor due to the inability to bathe, and the odor of instant foods such as cup noodles, and in some places these odors mix together. These unpleasant odors contribute to the stress of evacuation life for disaster victims, so there is a need for a composition that can deodorize all of these odors: feces, urine, body odor, and food odors.

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.

After extensive research in light of the above-mentioned problems, the inventors discovered that by combining specific fragrance ingredients and controlling the mass ratio of the two, it is possible to deodorize all feces and urine odors, food odors, and body odors without causing discomfort due to chemical odors, even at high concentrations.

That is, the present invention provides the following [1] to [12].

[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.

In this specification, "fecal odor" refers to the odor of human feces and urine, and causative substances include, for example, 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. "Body odor" refers to the odor emanating from the human body or worn clothing, and causative substances include, for example, 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. "Food odor" refers to the odor emanating from cooked instant foods, such as the odor emanating from cooked instant noodles, and causative substances include, for example, diacetyl and isovaleraldehyde.

<Component (A)>
The deodorant fragrance composition of the present invention contains, as component (A), an unsaturated aldehyde having no aromatic ring and a molecular weight of from 100 to 160 and a carbon number of from 9 to 10. Component (A) may be contained alone or in combination with two or more types.

Component (A) can be a commercially available product; for example, 2,4-dimethylcyclohex-3-ene-1-carbaldehyde is available as Triplal (a trade name from IFF). Furthermore, if the selected component (A) has enantiomers, it may be a single enantiomer or a mixture of enantiomers, such as a racemate.

<Component (B)>

<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, 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 even more preferably from 150 seconds to 10 minutes before.

When the deodorizing fragrance composition of the present invention is applied to a subject before exposure to one or more of feces and urine odors, body odors, and food odors, the application time 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 achieving a high deodorizing effect. Furthermore, from the viewpoint of suppressing discomfort caused by continued exposure to the fragrance and preventing a decrease in 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.

The application method is not particularly limited, as long as the deodorizing fragrance composition is applied to the subject before exposure to the target malodor. Furthermore, as long as the deodorizing fragrance composition is applied before exposure to the target malodor, 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 while the subject is exposed to the target malodor.

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), the deodorizing fragrance composition of the present invention may be impregnated directly into another article, and the impregnated article may be applied to a subject before exposure to the target malodor. Specific examples of the product 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 before exposure to the target malodor may wear the fragrance-impregnated mask, 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 the odors present when the care recipient is changed for a diaper. 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 user's nose when the care recipient enters the room. Furthermore, in the case of laundry detergents or laundry softeners, for example, the deodorizing fragrance composition can reach the user's nose due to the scent remaining on the laundry when the care recipient wears washed clothes.
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.

<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.

(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 the sticker was 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, thereby obtaining a fragrance-impregnated sticker.

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

(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.

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.

(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, manufactured by Kawamoto Sangyo Co., Ltd.) using a micropipette. The impregnated cotton ball was placed in a standard bottle (No. 11, 110 mL, manufactured by Hakuyo Glass Co., Ltd.), the bottle was closed, and the bottle was left to stand for 30 minutes under conditions of 25°C and 45% RH for evaluation.
(3) The subjects wore a nonwoven mask (super-three-dimensional mask, regular size, manufactured by Unicharm Corporation, weight 2.2 g/piece) without a fragrance-impregnated sticker attached, opened the lid of the bottle described in (2) above, and smelled the odor. The odor intensity at that time was recorded as the “malodor 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 subject, while wearing the fragrance-impregnated mask, opened the lid of the bottle from (2) above and smelled the odor, and the odor intensity was recorded as the "malodor 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. In the sensory test, the deodorizing effect of Example 1 was evaluated based on the level of deodorizing effect expressed, with Example 1 being given a score of "4" and the results being rated on a 7-point scale as follows. The higher the score, the better the deodorizing effect.

Evaluation criteria for "deodorizing effect on feces and urine odor" Rating 7: No feces or urine odor detected at all 6: Stronger deodorizing effect than Example 1 5: Slightly stronger deodorizing effect than Example 1 4: Equivalent deodorizing effect to Example 1 3: Slightly weaker deodorizing effect than Example 1 2: Weaker deodorizing effect than Example 1 1: No deodorizing effect

2. Body Odor Evaluation (1) Body odor was prepared using the following method: Three pieces of used clothing with a greasy, sour odor that had been worn by three adult men and women for one year and repeatedly washed were used. The used clothing was placed in an acrylic box (30 cm x 30 cm x 40 cm) with a lid on the top, closed, and left for 30 minutes before being used for evaluation.
(2) Each participant wore a nonwoven mask (ultra-three-dimensional mask, regular size, manufactured by Unicharm Corporation, weight 2.2 g/piece) without a fragrance-impregnated sticker attached, opened the lid on the top of the acrylic box described in (1) above, and smelled the odor. The odor intensity at that time was recorded as the “malodor intensity before wearing the mask.”
(3) The fragrance-impregnated mask was worn for 3 minutes under conditions of 25°C and 40% RH.
(4) After 3 minutes had passed, the subject, while wearing the fragrance-impregnated mask, opened the lid on the top of the acrylic box in (1) above and smelled the odor, and the odor intensity was recorded as the "malodor intensity after wearing the mask."
(5) The odor intensity after wearing the mask was evaluated according to the following criteria, and the average scores of five expert panelists are shown in each table.
