Description

Technical Field

[0001] The present invention relates to a fragrance composition, a cosmetic, and a modular ingredient for a fragrance composition. Background Art

[0002] Conventionally, the aroma of trees such as Hinoki cypress or similar aromas have been popular among all age groups, and fragrances that produce such tree-like aromas (tree-like fragrances) have been widely used in the fields of cosmetics and hygiene daily necessities. As tree-like fragrances, components extracted from natural trees or parts thereof, such as essential oils, are well-known.

[0003] However, there are users who feel that the aroma of only extraction components such as essential oils is not sufficient. Therefore, while maintaining the aroma tone of the tree, it is sometimes necessary to obtain an aroma that cannot be obtained only by essential oils. For this, for example, Patent Document 1 describes a perfume that has an aroma characteristic of Hinoki cypress and can obtain an aroma having a unique cool feeling (lively feeling) that does not exist in Hinoki cypress essential oil. The perfume described in Patent Document 1 contains, at least in water, a plurality of monocyclic terpenoid alcohols including terpinene-4-ol and / or α-terpineol.

Problems to be Solved by the Invention

[0008] In recent years, even people living in cities can experience nature such as forest bathing, and the opportunity to come into contact with the aroma of natural trees is increasing. As a result, when purchasing tree-like fragrances, not only do users want to feel the aroma tone of the trees, but the number of users who pursue the fresh aroma of fresh trees (fresh wood) is also increasing.

[0009] In view of the above situation, an object of one aspect of the present disclosure is to provide a fragrance composition that can impart a fresh aroma of fresh wood.

[0010]

Means for Solving the Problems

[0021] Figure 1 is a graph showing the results of detailed evaluation I of Examples 1-1 to 1-6.

[0022] Figure 2 is a graph showing the results of detailed evaluation I of Examples 1-7 to 1-11. DETAILED DESCRIPTION OF THE INVENTION

[0023] One aspect of the present disclosure is a fragrance composition containing a tree-like fragrance component, a specified component (A) and a component (B). Here, the component (A) and the component (B) can be said to be modular components for use in combination with the tree-like fragrance component as a skeleton component. In addition, one aspect of the present disclosure can be a modular component for combining with the tree-like fragrance component as a skeleton component to form a fragrance composition.

[0024] ​​In this specification, the "modular component" refers to a component that is used in combination with a small amount of the skeletal component that determines the skeletal component of the perfume composition, that is, the component of the perfume composition's aroma system (or aroma tone), and can endow the aroma of the perfume composition obtained by combining the skeletal component and the modular component with more characteristics while maintaining the aroma system (aroma tone) possessed by the skeletal component, or can increase or decrease the aroma characteristics possessed by the skeletal component. The aroma system or aroma tone can be an aroma classification represented by expressions such as woody, floral, fruity, citrus, green, etc. In addition, the "modular component" is sometimes also referred to as a modular composition, an additive component, an additive composition, etc.

[0025] The perfume composition according to one aspect of the present disclosure may provide a tree (woody or woody) aroma tone. In addition, specific examples of the tree aroma of such a tree perfume composition may mainly feel the aroma of hinoki cypress, cedar, sandalwood, cypress, fir, pine, Japanese cypress, etc., or the aroma of a mixture of two or more of these.

[0026] The tree aroma component as the skeletal component of the perfume composition of this aspect is not particularly limited as long as it is an aroma component that can provide the tree aroma tone. The aroma component in this aspect may be an aroma component obtained from natural trees, or an aroma component that provides a tree aroma obtained by blending compounds, or a mixture thereof. In addition, since the tree aroma component can provide a sufficient tree aroma even in a small amount and is easily obtained, it is preferably an essential oil obtained from natural trees or a composition containing essential oil. In this aspect, one or more of hinoki cypress essential oil and cedar essential oil are suitably used. These tree essential oils can be obtained through channels such as Aroma&Beauty Neroli (Yamamoto Perfumery Co., Ltd.).

[0027] Originally, tree aroma components have been very popular, but in recent years, there has been a greater tendency to pursue an aroma closer to that of natural plants, that is, the fresh aroma of living trees (living wood). However, the aroma of existing common tree aroma components (such as tree essential oils) is slightly different from the aroma of the natural raw material itself, and in many cases, the characteristics of the living wood aroma become weakened or disappear. This is considered to be because the composition may change during the process of extracting the components. Therefore, some users also feel that the existing tree aroma components alone are not sufficient.

[0028] In view of this, by combining the skeletal components of tree-like aroma components with the specified modular components of one aspect of the present disclosure, a tree-like fragrance composition can be provided, which can provide an aroma with the characteristics of fresh wood. In addition, one aspect of the present disclosure is a tree-like fragrance composition, which is composed of the skeletal components of tree-like aroma components and the specified modular components and can provide an aroma with the characteristics of fresh wood.

[0029] In this aspect, when using Chamaecyparis obtusa aroma components (for example, Chamaecyparis obtusa essential oil) as the skeletal components, it is possible to provide an aroma with enhanced fresh wood characteristics while maintaining the aroma characteristics of Chamaecyparis obtusa. On the other hand, when using tree-like aroma components other than Chamaecyparis obtusa aroma components (for example, essential oils of trees other than Chamaecyparis obtusa) as the skeletal components, it is also possible to provide an aroma with enhanced fresh wood characteristics of Chamaecyparis obtusa. That is to say, even without containing Chamaecyparis obtusa aroma components, it is possible to provide an aroma with strong fresh wood characteristics of Chamaecyparis obtusa.

[0030] The characteristics of the fresh wood aroma of Chamaecyparis obtusa refer to the aroma after freshly cutting a living Chamaecyparis obtusa tree trunk, and / or the aroma emitted when kneading the branches and leaves of a living Chamaecyparis obtusa. The intensity of this fresh wood characteristic of Chamaecyparis obtusa can be evaluated through the sensory evaluation of a trained professional panel, or through comparative tests with actual fresh wood of Chamaecyparis obtusa, etc. In addition, sensory evaluations of the aroma can also be carried out on more detailed items, and based on this, the characteristics of the fresh wood of Chamaecyparis obtusa can be evaluated. For example, when the present inventors evaluated the seven items of "refreshing aroma of citrus fruits", "aroma of green leaves", "refreshing floral aroma", "resinous oil aroma similar to almonds", "cool aroma with a sense of coolness", "refreshing aroma of wood chips", and "earthy woody aroma" respectively, it was found that the three items of "aroma of green leaves", "refreshing floral aroma", and "resinous oil aroma similar to almonds" were all strong and were related to the intensity of the fresh wood characteristic of Chamaecyparis obtusa. Therefore, by evaluating the "aroma of green leaves", "refreshing floral aroma", and "resinous oil aroma similar to almonds", it is also possible to objectively evaluate the intensity of the fresh wood characteristic of Chamaecyparis obtusa.

[0031] The tree-like fragrance composition of this aspect, in addition to having a strong aroma characteristic of the fresh wood of Chamaecyparis obtusa, can also bring a sense of freshness (also called the forest bathing feeling) as if actually taking a forest bath to the user who smells the composition. Here, the sense of freshness refers to the fresh feeling physically and / or mentally. Therefore, the fragrance composition of this aspect can bring a forest bathing feeling to the user who smells its aroma. In addition, the freshness of the aroma (the wet and moist aroma characteristics felt when taking a forest bath) is also very strong, and the impact of the top note of the tree-like aroma is also very large.

[0032] In order to form a tree-based fragrance composition, the amount of the modular component added to the tree-based fragrance component as the skeletal component may be 0.01 part by mass or more and 15 parts by mass or less, preferably 0.1 part by mass or more and 10 parts by mass or less, relative to 100 parts of the tree-based fragrance component as the skeletal component. By setting the amount within the above range, when the skeletal component is the hinoki cypress-based fragrance component, the fragrance of the resulting tree-based fragrance composition can be made closer to the fragrance of fresh wood, and when the skeletal component is the fragrance component of a tree other than hinoki cypress, the fragrance of the resulting tree-based fragrance composition can be made closer to the fragrance of fresh hinoki cypress wood. In addition, the effect that the resulting fragrance composition can provide a forest bathing feeling to the user can be further enhanced.

Examples

[0074] [Experimental Example 1] Using Chamaecyparis obtusa aroma components as the skeletal components

[0075] Samples (perfume compositions) of Examples 1-1 to 1-15 were prepared using Chamaecyparis obtusa essential oil as the skeletal component. The components of each example are shown in Table 1A.

[0076] <Overall Evaluation I>

[0077] For the samples of each example, evaluations were conducted by 4 ordinary reviewers who had actually smelled the fresh wood odor of Chamaecyparis obtusa. In addition, during the evaluation, the reviewers smelled the smelling strips impregnated with approximately 5 μL of each sample and scored them. In this evaluation, Examples 1-7, which contain no modular components and consist only of the skeletal component (Chamaecyparis obtusa essential oil), were used as control samples, and evaluations were conducted from the following perspectives: "characteristics of fresh Chamaecyparis obtusa wood", "forest bathing feeling", "freshness", and "impact of top note". The evaluation results are shown in Table 1A. The scores shown in Table 1A are the arithmetic means of the scores of all reviewers.

[0078] (Characteristics of fresh Chamaecyparis obtusa wood)

[0079] The intensity of the characteristics of fresh Chamaecyparis obtusa wood was evaluated. The characteristics of fresh Chamaecyparis obtusa wood refer to the odor characteristics including the aroma after freshly cutting a living Chamaecyparis obtusa trunk and the aroma emitted when kneading the branches and leaves of a living Chamaecyparis obtusa. The scoring criteria are as follows:

[0080] 0: None (the same as the control sample)

[0081] 1: Present, but very weak

[0082] 2: Present, but rather weak

[0083] 3: Present, but weak

[0084] 4: Present, but slightly weak

[0085] 5: Slightly strong

[0086] 6: Strong

[0087] 7: Considerably strong

[0088] 8: Very strong (the same as the aroma felt when actually smelling the fresh wood of Chamaecyparis obtusa).

[0089] (Forest bathing feeling)

[0090] The freshness similar to actual forest bathing was evaluated. The scoring criteria are as follows:

[0091] 0: None (the same as the control sample)

[0092] 1: There is, but very weak

[0093] 2: There is, but rather weak

[0094] 3: There is, but weak

[0095] 4: There is, but slightly weak

[0096] 5: Slightly strong

[0097] 6: Strong

[0098] 7: Considerably strong

[0099] 8: Very strong (the same as the forest bathing feeling when actually smelling the fresh wood of Chamaecyparis obtusa).

[0100] (Freshness)

[0101] The wet and moist aroma characteristics felt during forest bathing were evaluated. The scoring criteria are as follows:

[0102] 0: None (the same as the control sample)

[0103] 1: There is, but very weak

[0104] 2: There is, but rather weak

[0105] 3: There is, but weak

[0106] 4: There is, but slightly weak

[0107] 5: Slightly strong

[0108] 6: Strong

[0109] 7: Considerably strong

[0110] 8: Very strong (the same as the freshness felt when actually smelling the fresh wood of Chamaecyparis obtusa).

[0111] (Top note impact)

[0112] The intensity impression of the top note (the aroma felt when first smelling the odor) of the tree-like aroma was evaluated. The scoring criteria are as follows:

[0113] 0: None (the same as the control sample)

[0114] 1: Present, but very weak

[0115] 2: Present, but rather weak

[0116] 3: Present, but weak

[0117] 4: Present, but slightly weak

[0118] 5: Slightly strong

[0119] 6: Strong

[0120] 7: Rather strong

[0121] 8: Very strong (the same impact as the top note felt when actually smelling the fresh wood of Chamaecyparis obtusa).

[0122]

Table 1A

[0123]

[0124] As shown in Table 1A, when the modular component containing at least component (A) and component (B) is combined with the skeletal component as the Chamaecyparis obtusa-like aroma component (Examples 1-1 to 1-6), it can be found that the characteristics of the fresh wood of Chamaecyparis obtusa are stronger than when only using Chamaecyparis obtusa essential oil (Example 1-7, control sample). In addition, it was also found that the sense of forest bathing, freshness, and the impact of the top note of the tree-like aroma are stronger.

[0125] <Overall Evaluation II>

[0126] For the prepared partial samples (Examples 1-1, 1-2, and 1-4 to 1-10) and the newly prepared samples (Examples 1-16 and 1-17), 4 professional reviewers conducted evaluations. The way of smelling the odor was the same as the method used by ordinary reviewers during the evaluation. In this evaluation, Example 1-7, which contains no modular component and is composed only of the skeletal component (Chamaecyparis obtusa essential oil), was used as the negative control sample, and Example 1-5, which was rated as having the strongest "characteristics of fresh wood of Chamaecyparis obtusa" in the above-mentioned Overall Evaluation I (evaluation by ordinary reviewers), was used as the positive control sample. Evaluations were conducted from the perspectives of "characteristics of fresh wood of Chamaecyparis obtusa", "sense of forest bathing", and "freshness".

[0127] In the evaluation from any perspective, the scoring criteria are as follows:

[0128] 0: None (the same as Example 1-7, the negative control)

[0129] 1: Yes, but very weak

[0130] 2: Yes, but rather weak

[0131] 3: Yes, but weak

[0132] 4: Yes, but slightly weak

[0133] 5: Slightly stronger

[0134] 6: Strong

[0135] 7: Rather strong

[0136] 8: Very strong (the same as Examples 1 - 5 used as positive controls).

[0137] The evaluation results are shown in Table 1B (the component ratios are listed again). The scores shown in Table 1B are the arithmetic means of the scores given by all reviewers.

[0138]

Table 1B

[0139]

[0140] As shown in Table 1B, the evaluation by professional reviewers also indicates that by combining the modular components containing at least component (A) and component (B) with the skeletal components of the hinoki aroma components, the characteristics of fresh hinoki wood can be enhanced.

[0141] <Detailed Evaluation I>

[0142] For the prepared partial samples (Examples 1 - 1 to 1 - 11), a more detailed evaluation was conducted by 1 professional reviewer who had actually smelled the fresh hinoki wood. The way of smelling was the same as the methods in General Evaluations I and II. In this evaluation, the evaluation was carried out from the following more specific aspects: "a) Fresh citrus aroma", "b) Green leaf aroma", "c) Fresh floral aroma", "d) Resinous oil aroma similar to almond", "e) Cool aroma with a sense of coolness", "f) Fresh aroma of wood chips", "g) Earthy woody aroma". The scoring criteria are as follows:

[0143] 1: Not applicable at all

[0144] 2: Not applicable

[0145] 3: Not very applicable

[0146] 4: Neither of them

[0147] 5: Somewhat applicable

[0148] 6: Applicable

[0149] 7: Very applicable.

[0150] The results are shown in Table 2A (the composition of the samples is listed again). In addition, Figure 1 and Figure 2 evaluation charts of each sample are shown. Figure 1 Charts of Examples 1-1 to 1-6 are shown, Figure 2 and charts of Examples 1-7 to 1-11 are shown.

Table 2A

[0152]

[0153] <Detailed Evaluation II>

[0154] In addition, for some of the prepared samples (Examples 1-1, 1-2, 1-4 to 1-11, 1-16, and 1-17), they were also evaluated by 4 professional reviewers. The evaluation results are shown in Table 2B (the composition of the samples is listed again). It should be noted that the scores shown in Table 2B are the arithmetic means of the scores of all reviewers.

[0155]

Table 2B

[0156]

[0157] As shown in Table 2A and Table 2B, when the modular components containing at least component (A) and component (B) are combined with the skeletal components as the hinoki cypress-like aroma components (Examples 1-1 to 1-6, 1-16, and 1-17), the total scores of the three items that can be used as characteristic indicators of the fresh wood of hinoki cypress, namely, "b) green leaf-like aroma", "c) fresh floral aroma", and "d) resinous oil aroma similar to almond", are relatively high.

[0158] [Experimental Example 2] Using aroma components other than hinoki cypress-like aroma components as skeletal components

[0159] Examples 2-0 to 2-8 using cedarwood essential oil (tree-like skeletal component) as the skeletal component, and Examples 2-9 to 2-13 using lavender essential oil (flower-like skeletal component) as the skeletal component were prepared according to the components shown in Table 3A and the ratios shown in that table.

[0160] <Overall Evaluation I>

[0161] For the samples of each example, they were evaluated by 1 professional reviewer who had actually smelled the fresh wood odor of Chamaecyparis obtusa. Similar to <Overall Evaluation I (evaluation by ordinary reviewers)> in "Experimental Example 1", the evaluation was conducted from the perspectives of "characteristics of fresh wood of Chamaecyparis obtusa", "forest bathing feeling", "freshness", and "front note impact". However, for Examples 2-1 to 2-8, Example 2-0 consisting only of the skeleton component (cedar essential oil) without the module component was used as a control sample; for Examples 2-10 to 2-13, Example 2-9 consisting only of the skeleton component (lavender essential oil) without the module component was used as a control sample. Without using Chamaecyparis obtusa essential oil, it was evaluated whether the module components of each example could enhance the "characteristic feeling of fresh wood of Chamaecyparis obtusa", "forest bathing feeling", "freshness", and "front note impact". The method of smelling the odor and the scoring criteria were the same as those in <Detailed Evaluation I> of "Experimental Example 1". The evaluation results are shown in Table 3A.

[0162]

Table 3A

[0163]

[0164] As shown in Table 3A, it can be seen that even when using aroma components other than Chamaecyparis obtusa - type aroma components as the skeleton component, as long as the skeleton component is a tree - type aroma component, when combining the module component containing at least component (A) and component (B) with the skeleton component (Examples 2-1 to 2-4), a fragrance composition with strong characteristics of fresh wood of Chamaecyparis obtusa can be obtained. In addition, it was also found that the forest bathing feeling, freshness, and the front note impact of the tree - type aroma were enhanced. It should be noted that when the skeleton component is not a tree - type aroma component (Examples 2-10 to 2-13), even when using the module component containing component (A) and component (B), the corresponding effects were not obtained.

[0165] <Overall Evaluation II>

[0166] In addition, for some of the prepared samples (Examples 2-1 to 2-4, Example 2-6, and Example 2-8), they were also evaluated by 4 professional reviewers. The method of smelling the odor was the same as that when ordinary reviewers evaluated. In this evaluation, Example 2-0 consisting only of the skeleton component (cedar essential oil) without the module component was used as a negative control sample, and Example 1-5 prepared in "Experimental Example 1" (the example rated as having the strongest "characteristics of fresh wood of Chamaecyparis obtusa") was used as a positive control sample. The evaluation was conducted from the perspectives of "characteristics of fresh wood of Chamaecyparis obtusa", "forest bathing feeling", and "freshness". Here, in the evaluation of any one perspective, the scoring criteria were as follows:

[0167] 0: None (the same as Example 2-0 as the negative control)

[0168] 1: There is, but very weak

[0169] 2: Present, but rather weak

[0170] 3: Present, but weak

[0171] 4: Present, but slightly weak

[0172] 5: Slightly stronger

[0173] 6: Strong

[0174] 7: Rather strong

[0175] 8: Very strong (the same as Examples 1 - 5 used as positive controls).

[0176] The evaluation results are shown in Table 3B (the component ratios are listed again). The scores shown in Table 3B are the arithmetic means of the scores of all reviewers.

[0177]

Table 3B

[0178]

[0179] As shown in Table 3B, the evaluation by professional reviewers also shows that even when using aroma components other than hinoki cypress - type aroma components as the skeleton components, as long as the skeleton components are tree - type aroma components, when combining the modular components containing at least component (A) and component (B) with the skeleton components (Examples 2 - 1 to 2 - 4), a fragrance composition with strong fresh hinoki cypress wood characteristics can be obtained. In addition, it was also found that the forest bathing feeling and freshness were enhanced.
