[0061] In the above embodiment, sotolone may be further added. When sotolone is added, the mixing ratio is 3×10 -8 Mass % or less.

[0062] In consideration of the above, preferred examples of the formulation of the fragrance composition of the present invention, divided into the above-mentioned first embodiment and second embodiment, are shown in the following Tables 1 to 11, and Tables 12-1, 12-2, 13-1, 13-2, 14-1, and 14-2. Note that the blending ratio (mass %) of each fragrance compound in the tables is the value when the total mass of the fragrance components contained in the fragrance composition is taken as 100.0 mass %.

[0063] [First embodiment] <Formulation with 8 compounds> [Table 1]

[0064] [Table 2]

[0065] [Table 3]

[0066] [Table 4]

[0067] <9-compound formulation> [Table 5]

[0068] [Table 6]

[0069] <Formulation with 10 compounds> [Table 7]

[0070] [Table 8]

[0071] <Formulation with 13 compounds> [Table 9]

[0072] [Table 10]

[0073] <Formulation with 14 compounds> [Table 11]

[0074] [Second embodiment] <Formulation with 15 compounds> [Table 12-1] [Table 12-2]

[0075] <9-compound formulation> [Table 13-1] [Table 13-2]

[0076] <Formulation with 8 compounds> [Table 14-1] [Table 14-2]

[0077] In the above Tables 12-1, 12-2, 13-1, 13-2, 14-1, and 14-2, the four or three digits following the number symbol "#" represent the formula number. For each formula number, the leading "15", "9", and "8" represent the number of fragrance compounds, and the last two digits (such as "01", "02", etc.) represent the formula type. That is, the preferred embodiment according to the second embodiment of the present invention shown in Tables 12-1, 12-2, 13-1, 13-2, 14-1, and 14-2 are classified into 19 types represented by the numbers "01" to "32", and for each type, there are formulas with 15 compounds, formulas with 9 compounds, and formulas with 8 compounds. Note that the "13" type does not have a formula with 8 compounds, and is composed of a formula with 15 compounds and a formula with 9 compounds. Formulas belonging to the same type have similar scent tendencies, although the number of fragrance compounds used is different. That is, for example, the effect of a fragrance composition formulated with 15 compounds belonging to a certain family is similar to that of a formulation with 9 compounds and a formulation with 8 compounds belonging to the same family. In addition, there is a similarity in the tendency of the fragrance between each family. Specifically, the 14 families, "02", "04", "05", "09", "10", "11", "13", "21", "25", "27", "28", "29", "30", and "32", have different types and mixing ratios of individual fragrance compounds, but the effects exerted by the fragrance composition as a whole are similar. In other words, the formulations belonging to these families are within the range of the standard formulation of the fragrance composition according to the second embodiment of the present invention. The above matters will be shown more specifically in the examples described below.

[0088] Hereinafter, the embodiments of the present invention will be described with reference to illustrative examples, but the present invention is not limited to these examples.

[0089] <Formulation with 8 compounds> [Preparation of Fragrance Composition] The fragrance compositions of Examples 1 to 4 were prepared by blending the fragrance compounds according to the blending ratios (mass %) shown in Table 15. The fragrance compositions of Examples 1 to 4 correspond to Formulations 1 to 4 shown in Table 1 above, respectively.

[0090] [Table 15]

[0091] [Sensory evaluation of fragrance composition aroma 1] The fragrance compositions of Examples 1 to 4 were diluted with propylene glycol to 0.01% to prepare solutions for evaluation. Each evaluation sample was soaked into filter paper, and a sensory evaluation test was conducted in which five subjects rated the degree to which they felt that the fragrance corresponded to the evaluation items shown in Table 16 below on an 11-point scale from 0 points (not at all) to 10 points (at all).

[0092] [Table 16]

[0093] The results are shown in Figure 1. FIG. 1 is a graph showing the results of sensory evaluation 1 of the aromas of the fragrance compositions of Examples 1 to 4. The four graphs shown in Fig. 1, from the left, show the results of Example 1, Example 2, Example 3, and Example 4. The graph shown in Fig. 1 is a plot of the average values ​​(horizontal axis) of the results (scores) obtained for each evaluation item (vertical axis) for each fragrance composition. The same applies to Figs. 2 to 14 described below.

[0094] As shown in Figure 1, all the evaluation samples of Examples 1 to 4 tended to have high scores for words indicating positive impressions (positive words) such as "like," "pleasant," "flower-like," "fruity," "refreshing," and "memorable," and low scores for words indicating negative impressions (negative words) such as "dislike," "unpleasant," "harsh," "bitter," "earthy," "moldy," and "animal-like." In particular, the evaluation samples of Examples 1 and 2 showed a large difference between the scores for the positive words and the scores for the negative words, suggesting that the fragrance compositions have a good fragrance preference and are comfortable to people. Similar tests were conducted using evaluation samples with dilution rates of 0.1% and 1%, and results showed similar trends to those seen in the case of 0.01%. However, it was suggested that a dilution rate of approximately 0.01% is more preferable for the fragrance compositions of Examples 1 to 4.

[0095] [Sensory evaluation of fragrance composition aroma 2] In addition, in order to evaluate the degree to which the fragrance appeals to people's emotions, the evaluation items shown in Table 17 below were established, and an evaluation sample with a dilution rate of 0.01%, prepared in the same manner as in Sensory Evaluation 1 above, was soaked into filter paper, and a sensory evaluation test was conducted by five subjects on their impressions of the fragrance upon smelling it.

[0096] [Table 17]

[0097] The results are shown in Figure 2. FIG. 2 is a graph showing the results of sensory evaluation 2 of the aromas of the fragrance compositions of Examples 1 to 4. The four graphs shown in FIG. 2 show the results of Example 1, Example 2, Example 3, and Example 4, from the left.

[0098] As shown in Figure 2, for all the evaluation samples of Examples 1 to 4, there was a tendency for the scores to be high for words indicating positive emotions (positive words) such as "I like it," "It's pleasant," "It makes me feel positive," "I want to keep smelling it," and "It's soothing," and for the scores to be low for words indicating negative emotions (negative words) such as "It's unpleasant" and "I don't like it." In particular, for the evaluation samples of Examples 1 and 2, a large difference was obtained between the scores for the positive words and the scores for the negative words, suggesting that these are fragrance compositions that can enhance the positive emotions of people who smell the fragrance. In addition, similar tests were conducted using evaluation samples with dilution rates of 0.1% and 1%, and the results showed similar trends to those observed in the case of 0.01% above. However, it was suggested that a dilution rate of approximately 0.01% is more preferable for the fragrance compositions of Examples 1 to 4.

[0099] The evaluation items (words) in the above Sensory Evaluation 1 and Sensory Evaluation 2 were selected with the advice of a clinical psychologist. The same applies to the sensory evaluation described below.

[0100] <Formulation with 15 compounds> [Preparation of Fragrance Composition] A total of 19 types of fragrance compositions, Examples 1501 to 1532, were prepared by blending fragrance compounds according to the blending ratios (mass %) of Recipe Nos. 1501 to 1532 shown in Tables 12-1 and 12-2 above.

[0101] [Sensory evaluation of the fragrance composition] The fragrance compositions of Examples 1501 to 1532 were diluted with propylene glycol to 0.1% to prepare evaluation samples. Each evaluation sample was soaked in filter paper, and a sensory evaluation test was conducted in which 20 subjects (Japanese) rated the degree to which they felt that the evaluation items shown in Table 18 below corresponded to 11 points from 0 (not at all) to 10 (at all).

[0102] [Table 18]

[0103] The results are summarized in FIG. FIG. 3 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance compositions of Examples 1501 to 1532. In FIG. 3, for each fragrance composition, the average values ​​(horizontal axis) of the results (scores) obtained for each evaluation item (vertical axis) are plotted on a single graph.

[0104] As shown in FIG. 3, for all the evaluation samples of the fragrance compositions of Examples 1501 to 1532, the scores for the item "I like it" are concentrated around 5 to 6 points, which is a higher score than the other evaluation items and the variation between samples is small. Also, for the items "refreshing" and "soothing", scores were obtained in the range of about 4 to 6 points. In addition, the scores for the items "calm", "soft", "pleasant", "cool", "happy", "positive", and "lovable" were in the range of about 4 points, and the scores for the items "protective" and "enchanting" were in the range of about 3 to 4 points, with very little variation.

[0105] 4 to 6 show examples of the results for each evaluation sample. FIG. 4 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1502. FIG. 5 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1505. FIG. 6 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1530.

[0106] From the results shown in Figures 4 to 6, we can see a tendency for the scores to be high for words showing positive impressions and emotions (positive words) as mentioned above in Figure 3, and low for words showing negative impressions and emotions (negative words) such as "dislike," "unpleasant," "harsh," "bitter," "earthy," "moldy," and "animal-like."

[0107] These results suggest that the fragrance compositions of Examples 1501 to 1532 have a favorable scent and are fragrance compositions that people find pleasant and / or can enhance positive emotions in people who smell the scent.

[0108] In addition, the present inventors independently discovered a correlation coefficient that takes into account the correlation between the evaluation items, and the results of statistically analyzing the scores for each evaluation item showed that the effects of the fragrance compositions of Examples 1501 to 1532 described above could be supported. In particular, this statistical analysis suggested that the formulations belonging to the "02", "05" and "30" series were fragrance compositions that could exhibit more favorable effects.

[0109] It should be noted that the tendency for scores to be high for the evaluation items "strong" and "rich" may be due to factors such as the distance between the subject's nose and the filter paper when smelling the fragrance, and this is not necessarily a negative result.

[0110] [Sensory evaluation by subjects of different nationalities] Next, a sensory evaluation test was carried out by subjects of various nationalities using the evaluation sample of the fragrance composition of Example 1510 at a dilution rate of 0.1%, which was prepared in the same manner as in the sensory evaluation described above. The subjects were 36 Japanese, 13 Polish, 5 Taiwanese, and 2 Indian. The fragrance composition of Example 1510 was used as the evaluation sample for this test because, among the above-mentioned Examples 1501 to 1532, Example 1510 had roughly average results (scores) for all evaluation items and was therefore considered appropriate for investigating the fragrance preferences of subjects of nationalities other than Japan.

[0111] The results are shown in Figures 7 to 10. FIG. 7 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1510 by Japanese subjects. FIG. 8 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1510 by Polish subjects. FIG. 9 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1510 by Taiwanese subjects. FIG. 10 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 1510 by Indian subjects.

[0112] As shown in Figures 7 to 10, there was a tendency for the impressions and thoughts (feelings) of the same evaluation sample to vary slightly depending on the nationality of the subjects. However, as exemplified by the high scores given to the "I like it" item by all subjects, it was suggested that the fragrance composition of the present invention is a fragrance that is liked regardless of nationality.

[0113] <Formulation with 8 compounds> [Preparation of Fragrance Composition] The fragrance composition of Example 802 was prepared by blending fragrance compounds according to the blending ratio (mass %) of Recipe No. 802 shown in Table 14-1 above.

[0114] [Sensory evaluation of the fragrance composition] Using the same procedures as those described above for Examples 1501 to 1532, an evaluation sample was prepared at a dilution rate of 0.1% of the flavor composition of Example 802, and a sensory evaluation test was carried out by 10 subjects (Japanese).

[0115] The results are shown in Figure 11. FIG. 11 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance composition of Example 802.

[0116] From the results shown in Figure 11, it was confirmed that the fragrance composition of Example 802 showed similar trends to the results obtained using the fragrance compositions of Examples 1501 to 1532 described above (see Figures 3 to 6). In particular, compared with the results of Example 1502 (Figure 4) prepared based on Recipe No. 1502, which belongs to the same family as Recipe No. 802, the fragrance composition of Example 802 has a larger difference between the scores for positive words and the scores for negative words, and it can be seen that a more distinct result was obtained. Also, it is noteworthy that in both Example 802 (Figure 11) and Example 1502 (Figure 4), the scores for the items "like" and "pleasant" are clearly higher than the scores for the items "dislike" and "unpleasant."

[0117] [Comparative test with fragrance compositions having various compositions] Next, evaluation samples were prepared at a dilution rate of 0.1% of the fragrance composition of Example 802 and fragrance compositions prepared by blending fragrance compounds according to the blending ratios (mass %) of Comparative Examples 1 to 4 shown in Table 19 below, and a sensory evaluation test was conducted by 10 subjects (Japanese) using the same procedure as described above for Examples 1501 to 1532.

[0118] [Table 19]

[0119] The results are summarized in FIG. FIG. 12 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance compositions of Example 802 and Comparative Examples 1 to 4. In FIG. 12, Example 802 is indicated by a circle, Comparative Example 1 by an upward triangle, Comparative Example 2 by a square, Comparative Example 3 by a diamond, and Comparative Example 4 by a downward triangle.

[0120] From the results shown in FIG. 12, it can be seen that the scores for the items "I like it," "mild," "soft," "sweet," "pleasant," "flowery," "fruity," "warm," "cool," "foresty," and "refreshing" for the fragrance composition of Example 802 are significantly higher than those for the fragrance compositions of Comparative Examples 1 to 4. In addition, the scores for the items "healing," "want to protect," "want to smell it forever," "happy," "unforgettable," "positive," and "lovely" for the fragrance composition of Example 802 are also significantly higher than those for the fragrance compositions of Comparative Examples 1 to 4. It is noteworthy that all of the above items are words (positive words) that indicate positive impressions and feelings of people who smell the fragrance.

[0121] [Comparative test with commercially available perfumes] Next, an evaluation sample of the fragrance composition of Example 802 at a dilution rate of 0.1% and evaluation samples of three types of commercially available perfumes were prepared, and a sensory evaluation test was conducted by 10 subjects (Japanese) using the same procedures as described above for Examples 1501 to 1532.

[0122] The perfumes used in this test were perfume 1 (manufactured by BVLGARI, product name "Petits et Mamans"), perfume 2 (manufactured by DEMETER, product name "Baby Powder"), and perfume 3 (manufactured by Creature, product name "Creature d Anges"). Analysis by gas chromatography-mass spectrometry (GC-MS) revealed that the number of fragrance compounds detected and identified in perfumes 1-3 was 24 for perfumes 1 and 2, and 43 for perfume 3. In addition, since perfumes 1-3 contained compounds that were difficult to identify from the obtained chromatograms and mass spectra, the number of fragrance compounds actually contained is thought to be greater than the above.

[0123] The results are summarized in FIG. FIG. 13 is a graph showing the results of a sensory evaluation of the fragrance composition of Example 802 and commercially available perfumes 1 to 3. In FIG. 13, Example 802 is represented by a circle, Perfume 1 by an upward pointing triangle, Perfume 2 by a diamond, and Perfume 3 by a square.

[0124] From the results shown in FIG. 13, it can be seen that the scores for the fragrance composition of Example 802 in the categories of "I like it," "mild," "soft," "pleasant," "flowery," "light (faint)," "fruitful," "warm," "cool," "foresty," and "refreshing" are significantly higher than those for perfumes 1 to 3. In addition, the scores for the fragrance composition of Example 802 in the categories of "soothing," "makes me want to protect," "want to keep smelling it," "happy," "makes me feel positive," and "lovely" are also significantly higher than those for perfumes 1 to 3. It is noteworthy that all of the above categories are words (positive words) that indicate positive impressions and feelings of people who smell the fragrance.

[0125] <9-compound formulation> [Preparation of Fragrance Composition] The fragrance compounds were blended according to the blending ratios (mass %) of Recipe No. 902 shown in Table 13-1 and Recipe No. 913 shown in Table 13-2 above, to prepare the fragrance compositions of Examples 902 and 913.

[0126] [Sensory evaluation of the fragrance composition] Using the same procedures as described above for Examples 1501 to 1532, evaluation samples were prepared at a dilution rate of 0.1% for the fragrance compositions of Examples 902 and 913, and a sensory evaluation test was conducted by 11 subjects (Japanese).

[0127] The results are summarized in FIG. FIG. 14 is a graph showing the results of a sensory evaluation of the fragrance of the fragrance compositions of Examples 902 and 913. In FIG. 14, Example 902 is indicated by a circle and Example 913 is indicated by an upward pointing triangle.

[0128] 14, it can be seen that the fragrance compositions of Examples 902 and 913 generally have similar scent tendencies. In particular, the fragrance composition of Example 902 tended to score higher than the fragrance composition of Example 913 in the categories of "like," "pleasant," and "refreshing."
