Description

[Technical Field]

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

[0002] Forsythia is a plant of the Oleaceae family, native to China. It is a deciduous tree that also grows in Japan, blooming around March, then sprouting new leaves, which fall off around December.

[0003] Forsythia leaves are used as tea leaves. Harvested forsythia leaves are washed and dried before being used as tea leaves. Forsythia tea is known to be rich in polyphenols with high antioxidant properties. Forsythia also contains large amounts of arctigenin and arctiin, which have anti-pancreatic cancer and anti-inflammatory activities (Patent Document 1).

[0004] In addition to the leaves, forsythia flowers have also been attracting attention. It is said that when forsythia flowers (forsythia fruit flowers) are dried in the sun and then brewed into a decoction, they are effective as a diuretic, laxative, and for preventing high blood pressure (Non-cited references 1 and 2). In recent years, the medicinal, powdery floral fragrance of forsythia flowers has also attracted attention, and attempts have been made to reproduce this fragrance composition.

[0007] However, the reproducibility of the fragrance is low, and the fragrance of forsythia flowers is not very satisfactory.

[0008] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fragrance composition that has a high degree of reproducibility of the fragrance of forsythia flowers and is highly palatable. [Means for solving the problem]

[0009] In order to solve the above problems, the present inventors have conducted extensive research into the aromatic components of forsythia flowers. As a result, they have found that by incorporating major aromatic components such as methyl salicylate, ethyl salicylate, methyl benzoate, ethyl benzoate, linalool, and limonene into a fragrance composition, and by incorporating methyl salicylate or ethyl salicylate and methyl benzoate or ethyl benzoate in a specific mass ratio, it is possible to reproduce a floral scent that is centered around an aroma evocative of the inherent medicinal effects of forsythia flowers, and that also has a powdery floral scent by incorporating linalool and limonene, and that is highly palatable, thereby obtaining a fragrance composition, and have completed the present invention.

[0010] That is, the forsythia flower-like fragrance composition of the present invention comprises (A) methyl salicylate and / or ethyl salicylate, (B) methyl benzoate and / or ethyl benzoate, and (C) methyl benzoate and / or ethyl benzoate. C) linalool and / or limonene, the total content of the components (A) and (B) is 50 to 90 mass %, and the mass ratio (A / B) is 1 to 10.

[0011] In the present invention, the content of component (C) may be 10 to 50% by mass. [Effects of the Invention]

[0012] The forsythia flower-like fragrance composition of the present invention provides a fragrance composition that has a high degree of reproducibility of the fragrance of forsythia flowers and is highly palatable. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments. The present invention is not limited to the respective configurations described below, and various modifications are possible within the scope of the claims. Embodiments and examples obtained by appropriately combining the technical means disclosed in different embodiments and examples are also included in the technical scope of the present invention. Furthermore, in this specification, unless otherwise specified, "A to B" representing a numerical range means "greater than or equal to A and less than or equal to B."

[0014] <Forsythia flower-like fragrance composition> The forsythia flower-like fragrance composition of this embodiment (hereinafter, sometimes simply referred to as the "fragrance composition") contains (A) methyl salicylate and / or ethyl salicylate, (B) methyl benzoate and / or ethyl benzoate, and (C) linalool and / or limonene.

[0015] The forsythia flower-like fragrance composition according to this embodiment has the fragrance of forsythia flowers. Regarding forsythia, forsythia is a dioecious deciduous shrub of the genus Forsythia of the family Oleaceae, native to China and widely distributed in Japan. Forsythia species include Forsythia spp., Forsythia koraiensis, and Forsythia chinensis. Forsythia flowers have a medicinal fragrance and exhibit a powdery, floral-like floral fragrance.

[0016] The component (A) contained in the fragrance composition according to this embodiment is methyl salicylate and / or ethyl salicylate. Methyl salicylate is the main component of wintergreen oil and is contained in many essential oils. Methyl salicylate has a wintergreen-like green color and a sweet, phenolic fragrance. Ethyl salicylate has a fragrance similar to that of methyl salicylate, but also possesses floral and spicy fragrance notes.

[0017] The content of component (A) in the fragrance composition according to this embodiment is preferably 5 to 80% by mass. When the content of component (A) is 5% by mass or more, the medicinal fragrance unique to forsythia flowers can be recognized, and when components (B) and (C), described below, are included, the fragrance of forsythia flowers can be perceived with high reproducibility. Furthermore, when the content of component (A) is 80% by mass or less, the floral notes of components (B) and (C) can be presented in a balanced manner without giving off a strong medicinal feeling.

[0018] Component (B) contained in the fragrance composition of the present invention is methyl benzoate and / or ethyl benzoate. Methyl benzoate is contained in natural fragrances such as clove and ylang-ylang. Methyl benzoate has a dry, fruity scent with a wintergreen, green aroma. Similar to methyl benzoate, ethyl benzoate has a fruity, wintergreen, green aroma.

[0019] The content of the component (B) in the fragrance composition according to this embodiment is preferably 5 to 50% by mass. When the content of the component (B) is 5% by mass or more, the above-mentioned component (A) and the below-described component (C) By including component (A) and component (C), the fragrance of forsythia flowers can be perceived with high reproducibility. Furthermore, by limiting the content of component (B) to 50% by mass or less, the medicinal and floral effects of components (A) and (C) can be balanced without giving an overly strong fruity feel.

[0020] In the fragrance composition according to this embodiment, the combined amount of components (A) and (B) is 50% by mass to 90% by mass of the total amount of the fragrance composition. By making the combined amount 50% by mass or more, the palatable characteristics of forsythia flowers can be retained, while by making the combined amount 90% by mass or less, the fragrance of forsythia flowers is not too strong and can be made more palatable.

[0021] Furthermore, in the fragrance composition according to this embodiment, the mass ratio (A / B) of component (A) to component (B) is 1 to 10. When the mass ratio is 1 or more, it is possible to present a medicinal fragrance that is a characteristic fragrance of forsythia flowers, and when it is 10 or less, it is possible to present a powdery floral note that is a characteristic direction of forsythia flowers.

[0022] The component (C) contained in the fragrance composition according to this embodiment is linalool and / or limonene. Linalool is widely contained in natural fragrances, including rose and bergamot. It has a gentle floral fragrance note. Linalool has optical isomers, but these are not particularly limited in the fragrance note of the fragrance composition according to this embodiment. Limonene is contained in large amounts in natural fragrances of citrus fruits, including orange. Limonene exhibits a fresh, refreshing citrus fragrance note. Limonene has optical isomers, but these are not particularly limited in the fragrance note of the fragrance composition according to this embodiment.

[0023] The content of component (C) in the fragrance composition according to this embodiment is preferably 10 to 50% by mass. When the content of component (C) is 10% by mass or more, the presence of components (A) and (B) described above allows the fragrance of forsythia flowers to be perceived with higher reproducibility. Furthermore, by keeping the content of component (C) at 50% by mass or less, the fresh feeling unique to component (C) can be suppressed.

[0024] The fragrance composition according to this embodiment can be added to skin cosmetics, hair cosmetics, toiletry products, etc. Examples of skin cosmetics include facial cleansers, body cleansers such as body shampoos, makeup products, face care products, and body care products, while examples of hair cosmetics include hair cleansers such as shampoos, rinses, conditioners, and styling agents.

[0025] The amount of the fragrance composition of the present invention to be added to a cosmetic product cannot be generally defined depending on the formulation and fragrance properties of the cosmetic product in question, but in general, the amount to be added to a cosmetic product is preferably 0.001 to 20% by mass, and more preferably 0.1 to 1.0% by mass. [Example]

[0026] The forsythia flower-like fragrance composition according to this embodiment will be described in more detail below with reference to examples and comparative examples, but the fragrance composition is not limited to the following examples.

[0027] The evaluation of the fragrance compositions is described below. The flavor compositions shown in Tables 1 and 2 were prepared. A sensory evaluation was conducted by three expert panelists. They compared the fragrance of forsythia (Chinese Forsythia) flowers and evaluated whether the fragrance had a medicinal scent and a floral character that was partially reminiscent of a powdery floral scent based on the following scoring criteria, and the average scores of the three panelists were calculated. The reproducibility of the forsythia flower fragrance was then judged based on the following scoring criteria using this average.

[0028] 1 point: The scent of forsythia flowers is not accurately reproduced. 2 points: A slight reproduction of the scent of forsythia flowers is observed. 3 points: Reproduction of the scent of forsythia flowers is observed. 4 points: The scent of forsythia flowers is highly reproduced. 5 points: The scent of forsythia flowers is reproduced to an extremely high degree.

[0029] <Score criteria for reproducibility of forsythia flower fragrance> ◎: Excellent - 4.5 points or more ○: Excellent - 3.0 points or more, less than 4.5 points △: Poor 2.0 points or more, less than 3 points ×: Very poor - Less than 2.0 points
