Description

Technology Field

[0001] The various embodiments disclosed in this document relate to perfume compositions with excellent fragrance persistence. More specifically, the invention relates to a perfume composition having high fragrance preference, excellent fragrance persistence, low skin irritation, and excellent long-term storage stability, by quantifying a fragrance mixture consisting of musk-based fragrances, woody-amber-based fragrances, and floral-based fragrances at a specific mixing ratio, and incorporating a solubilizer, a humectant, a preservative, and an antioxidant into a perfume base with denatured ethanol as the main component in specific content ranges. Background Technology

[0002] With economic development and the improvement of living standards, the desire to beautify one's appearance is increasing, and various cosmetics and perfumes are being proposed and marketed as materials for enhancing one's appearance.

[0003] Perfume is a type of cosmetic manufactured by mixing fragrant substances in appropriate proportions and dissolving them in alcohol, and is applied by spraying it on parts of the body or clothing; it mixes with body heat or body odor emanating from the skin to emit a fragrance. When perfume is used on the body or clothing in this way, bad odors emanating from the body are reduced or blocked, and the pleasant scent emitted from the perfume evokes a favorable impression from others, which is why it is highly preferred by modern people regardless of gender.

[0004] Meanwhile, the fragrance of a perfume is determined by the harmony of top notes, middle notes, and base notes, in which multiple fragrance ingredients with different volatility levels are released sequentially over time. However, if the types and blending ratios of the ingredients constituting each note are inappropriate, there have been problems such as the scent rapidly dissipating and its longevity decreasing even if the initial scent is excellent, or conversely, the scent becoming excessively heavy and dull, leading to reduced desirability.

[0005] Furthermore, conventional perfumes use large amounts of alcohol to dissolve fragrances, which can dry out the skin and cause irritation or skin problems for sensitive users. Additionally, if the compatibility between the fragrance and the base is insufficient, issues such as cloudiness or phase separation may occur during storage, or the fragrance components may oxidize, causing the scent to deteriorate.

[0006] Accordingly, there is a continuously increasing demand for perfume compositions that have high fragrance preference, excellent scent longevity, low skin irritation, and stability even during long-term storage. The problem to be solved

[0007] The present disclosure aims to provide a perfume composition with high fragrance preference and excellent fragrance longevity by employing a fragrance mixture comprising a musk-based fragrance, a woody-amber-based fragrance, and a floral-based fragrance in a specific blending ratio, in order to solve the problems of the aforementioned prior art.

[0008] Furthermore, the present disclosure aims to provide a perfume composition that has low skin irritation and suppresses cloudiness, phase separation, and fragrance deterioration during long-term storage by incorporating a solubilizer, a humectant, a preservative, and an antioxidant into a perfume base having denatured ethanol as the main component in specific content ranges.

[0009] Conventional perfumes have limitations in that they focus on the selection of fragrance types, resulting in broad or unclear blending ratios of fragrances by note, and merely dissolve fragrances in alcohol, failing to simultaneously consider fragrance longevity, skin irritation, and storage stability. Accordingly, the present disclosure aims to provide a perfume composition that simultaneously considers fragrance, longevity, skin irritation, and stability by limiting the blending ratios of musk-based and floral-based fragrances to a specific range based on woody-amber-based fragrances that contribute to fragrance longevity, and by blending auxiliary components of the perfume base within a critical content range. means of solving the problem

[0010] A perfume composition according to one embodiment of the present disclosure comprises 75 to 84 weight% denatured ethanol, 15 to 20 weight% fragrance mixture, 0.5 to 1.5 weight% 1,3-butylene glycol, 0.1 to 1.0 weight% PEG-40 hydrogenated castor oil, 0.1 to 1.0 weight% 1,2-hexanediol, and 0.1 to 1.0 weight% tocopheryl acetate, wherein the fragrance mixture comprises a musk-based fragrance, a woody-amber-based fragrance, and a floral-based fragrance, the musk-based fragrance comprises habanolide and exaltolide, and the woody-amber-based fragrance comprises Iso E Super, Cetalox, Trisamber, Ambroxan, and Ambergris T. The floral fragrance may include Hedione and Jasmin Sambac Absolute, and the fragrance mixture may include 50 to 70 parts by weight of the musk fragrance and 30 to 45 parts by weight of the floral fragrance per 100 parts by weight of the woody-amber fragrance. Effects of the invention

[0011] According to the present disclosure, the following effects can be obtained.

[0012] The perfume composition of the present disclosure includes musk-based fragrances and floral-based fragrances in a specific mixing ratio based on woody-amber-based fragrances that contribute to fragrance longevity, thereby stably maintaining the lingering scent of the base notes for a long time while harmoniously expressing the brightness of the middle notes, so as to provide a perfume with high fragrance preference and excellent fragrance longevity.

[0013] In addition, by incorporating a solubilizing agent such as PEG-40 hydrogenated castor oil into denatured ethanol at a specific content, the compatibility between the fragrance mixture and the base is improved, thereby providing a stable perfume in which cloudiness and phase separation are suppressed even during long-term storage.

[0014] In addition, by including a moisturizer such as 1,3-butylene glycol, skin dryness caused by alcohol is alleviated, skin irritation is reduced, and at the same time, it acts as a fixative to further improve fragrance longevity.

[0015] Furthermore, by including 1,2-hexanediol as a preservative and tocopheryl acetate as an antioxidant, the deterioration of the fragrance and discoloration caused by the oxidation of the fragrance components are suppressed, thereby improving long-term storage stability and ensuring low skin irritation.

[0016] Furthermore, in one embodiment, if the base note fragrance is encapsulated and released in a sustained-release manner, the fragrance longevity may be further enhanced, and if an anti-stress essential oil is further included, a functional perfume exhibiting stress relief and antibacterial functions may be provided, and if the content of the labeled fragrance allergen component is controlled, skin hypoallergenicity may be further enhanced.

[0017] Consequently, the present disclosure is a perfume composition that comprehensively considers fragrance, fragrance longevity, skin hypoallergenicity, and storage stability, and can provide a more stable and reproducible effect compared to conventional perfumes. Brief explanation of the drawing

[0018] Figure 1 may be a component of the perfume composition of the present disclosure. FIG. 2 is a graph showing the change in the headspace GC-MS residual fragrance peak area according to the elapsed time after skin application for the fragrance compositions of Example 1 and Example 5 of the present invention. Specific details for implementing the invention

[0019] Hereinafter, embodiments according to the present disclosure will be described in detail. However, the following embodiments are intended to illustrate the present disclosure, and the scope of the rights of the present disclosure is not limited or restricted by the following embodiments. A person skilled in the art to which the present disclosure pertains may make various changes, substitutions, additions, or equivalent modifications within the scope of the technical spirit of the present disclosure, and such changes, substitutions, additions, or equivalent modifications should be understood as being included within the scope of the present disclosure.

[0020] Expressions such as “comprising,” “equipped,” and “having” as used in this specification are used in a sense that does not exclude the existence or addition of components other than those described, unless specifically stated otherwise. Furthermore, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0021] In this specification, “weight%” refers to an amount based on 100 weight% of the total perfume composition unless otherwise specifically stated. Additionally, when describing the content of each fragrance component within the fragrance mixture, it refers to an amount based on 100 weight% of the total fragrance mixture unless otherwise specifically stated. In this specification, the content range of each component may be selected so that the total composition is 100 weight%, and this does not mean that the upper or lower limit of each component must be selected simultaneously.

[0022] In this specification, “parts by weight” refers to a relative weight ratio based on a specific component or a specific group of components. For example, the expression “50 to 70 parts by weight of musk-based fragrance with respect to 100 parts by weight of woody-amber-based fragrance” means that when the total content of woody-amber-based fragrance is converted to 100, the total content of musk-based fragrance has a relative weight ratio of 50 to 70.

[0023] In this specification, “fragrance mixture” refers to a mixture of fragrance components that form the scent of a perfume composition. In one embodiment, the fragrance mixture may include a musk-based fragrance, a woody-amber-based fragrance, and a floral-based fragrance.

[0024] In this specification, “musk-based fragrance” refers to a group of fragrances that impart skin adhesion, a soft lingering scent, and retention. In one embodiment, the musk-based fragrance may include habanolide and exaltolide. The habanolide and exaltolide can impart a musk scent while also serving to smoothly connect the lingering scent.

[0025] In this specification, “woody-amber fragrance” refers to a group of fragrances that impart depth and persistence in the woody, amber, ambergris, or resin series. In one embodiment, the woody-amber fragrance may include Iso E Super, Cetalox, Trisamber, Ambroxan, and Ambergris T. The woody-amber fragrance may form the base note of a perfume composition and impart persistence and depth of a woody-amber-musk accord.

[0026] In this specification, “floral fragrance” refers to a group of fragrances that impart brightness, diffusion, and fragrance balance to the middle notes. In one embodiment, the floral fragrance may include Hedione and Jasmin Sambac Absolute. The floral fragrance can alleviate the heaviness of woody-amber fragrances and, when combined with musk fragrances, enhance the softness and dimensionality of the fragrance.

[0027] A perfume composition according to the present disclosure may be a perfume composition designed to simultaneously improve scent preference, scent persistence, usability, and storage stability by combining a fragrance mixture comprising a musk-based fragrance, a woody-amber-based fragrance, and a floral-based fragrance in a specific mixing ratio, and a perfume base comprising denatured ethanol as the main component in a specific content range.

[0028] Hereinafter, a perfume composition according to the present disclosure will be described in detail.

[0029] Figure 1 may be a component of the perfume composition of the present disclosure.

[0030] A perfume composition according to the present disclosure may comprise 75 to 84 weight% of denatured ethanol, 15 to 20 weight% of a fragrance mixture, 0.5 to 1.5 weight% of 1,3-butylene glycol, 0.1 to 1.0 weight% of PEG-40 hydrogenated castor oil, 0.1 to 1.0 weight% of 1,2-hexanediol, and 0.1 to 1.0 weight% of tocopheryl acetate. The entire composition of the perfume composition may be composed of 100 weight%.

[0031] In one embodiment, the perfume composition may comprise 80 wt% denatured ethanol, 17.5 wt% fragrance mixture, 1.0 wt% 1,3-butylene glycol, 0.5 wt% PEG-40 hydrogenated castor oil, 0.5 wt% 1,2-hexanediol, and 0.5 wt% tocopheryl acetate.

[0032] However, the above composition ratio is not merely an arbitrary setting, but a range established to mutually amplify the effects of each component contributing to fragrance expression, fragrance persistence, solubilization stabilization, skin moisturization, preservation, and antioxidant properties. In particular, it has been confirmed that exceeding this range may result in problems such as reduced fragrance persistence, decreased fragrance preference, reduced storage stability due to turbidity or phase separation, or skin irritation.

[0033] In one embodiment, denatured ethanol serves as the main solvent of the perfume base, dissolving the fragrance mixture and imparting volatility and diffusivity to the fragrance, thereby enabling the top notes to be rapidly expressed at the beginning of use.

[0034] It may be preferable for the denatured ethanol to comprise 75 to 84 weight percent based on 100 weight percent of the total perfume composition.

[0035] If the denatured ethanol is less than 75% by weight, the dissolution of the fragrance mixture is insufficient, and the diffusion of the fragrance is reduced, which may result in a problem where the fragrance power is weak. On the other hand, if it exceeds 84% ​​by weight, the relative content of fragrance and moisturizer decreases, leading to reduced fragrance longevity, and the skin may become excessively dry due to the alcohol, potentially causing irritation. Therefore, the above range may be a critical range for simultaneously ensuring fragrance power and low skin irritation.

[0036] In one embodiment, the fragrance mixture includes musk-based fragrance, woody-amber-based fragrance, and floral-based fragrance as the main component for expressing the scent of the perfume, and exhibits a scent based on woody, amber, and musk overall.

[0037] It may be preferable for the fragrance mixture to comprise 15 to 20 weight percent based on 100 weight percent of the total perfume composition.

[0038] If the fragrance mixture is less than 15% by weight, the scent is weak and the duration is excessively reduced, so the function as a perfume is not fully expressed. On the other hand, if it exceeds 20% by weight, the scent is excessively strong, which may increase aversion from the user and others, and may increase skin irritation. Therefore, the above range is a critical range for stably securing the desirability of the scent and the scent duration.

[0039] The above musk-based fragrance includes habanolide and exaltolide. Since musk-based fragrances have a macrocyclic structure with a large molecular weight and a slow volatilization rate, they serve to connect base notes and middle notes and gently retain the lingering scent to form a lingering scent that adheres to the skin.

[0040] The woody-amber fragrances mentioned above include Iso E Super, Cetalox, Trisamber, Ambroxan, and Ambergris T. Woody-amber fragrances form low-volatility base notes, giving depth and warmth to the scent, and play a key role in determining scent longevity.

[0041] The above floral fragrances include Hedione and Jasmin Sambac Absolute. The floral fragrances form middle notes to give brightness and dimensionality to the scent, and play a role in balancing the scent by alleviating the heaviness of the woody-amber fragrances.

[0042] Preferably, the above fragrance mixture comprises 50 to 70 parts by weight of the musk-based fragrance and 30 to 45 parts by weight of the floral-based fragrance, based on 100 parts by weight of the woody-amber-based fragrance. If the musk-based fragrance is less than 50 parts by weight or the floral-based fragrance is less than 30 parts by weight, the proportion of the woody-amber-based fragrance is excessive, resulting in a heavy and dull scent, which lowers initial preference. Conversely, if the musk-based fragrance exceeds 70 parts by weight, the scent becomes monotonous and skewed toward a powdery quality, and if the floral-based fragrance exceeds 45 parts by weight, the proportion of highly volatile middle notes is excessive, causing the scent to dissipate quickly and reducing fragrance longevity. Therefore, the above mixing ratio is a critical range for simultaneously ensuring both scent preference and fragrance longevity.

[0043] In one embodiment, the fragrance mixture may comprise 13 to 17 weight% habanolide, 7 to 11 weight% exaltolide, 16 to 20 weight% iso-i super, 6 to 10 weight% cetalox, 4 to 8 weight% trisamber, 3 to 7 weight% ambroxan, 2 to 6 weight% ambergris T, 10 to 14 weight% hedion, 2 to 6 weight% jasmine sambac absolute, and the remainder being other auxiliary fragrances, based on 100 weight% of the total fragrance mixture. The other auxiliary fragrances may be included as the remainder after deducting the total content of the habanolide, exaltolide, iso-i super, cetalox, trisamber, ambroxan, ambergris T, hedion, and jasmine sambac absolute from 100 weight% of the total fragrance mixture. In one embodiment, the other auxiliary fragrance may be included in an amount of 10 to 25 weight%, preferably 15 to 22 weight%, based on 100 weight% of the total fragrance mixture. In one embodiment, the other auxiliary fragrance may include at least one of a citrus fragrance, a green fragrance, and a spicy fragrance to reinforce the top note or middle note. For example, the citrus fragrance may include bergamot oil or lemon oil, the green fragrance may include galbanum, and the spicy fragrance may include pink pepper.

[0044] In one embodiment, 1,3-butylene glycol acts as a moisturizer and fixative to alleviate skin dryness caused by alcohol, thereby reducing skin irritation, while simultaneously controlling the volatilization rate of fragrance ingredients to improve fragrance longevity.

[0045] It may be preferable to include 0.5 to 1.5 weight percent of 1,3-butylene glycol based on 100 weight percent of the total perfume composition.

[0046] If 1,3-butylene glycol is less than 0.5 weight%, the moisturizing and retention effects are insufficient, so the skin irritation and fragrance longevity enhancement effects are not sufficiently expressed. On the other hand, if it exceeds 1.5 weight%, the viscosity of the composition increases, causing stickiness, and the spreadability and sensory properties may be reduced when sprayed. Therefore, the above range is a critical range that simultaneously satisfies the moisturizing and retention effects and the user experience.

[0047] In one embodiment, PEG-40 hydrogenated castor oil acts as a solubilizer to improve the miscibility between the fragrance mixture, denatured ethanol, and water, thereby suppressing cloudiness and phase separation of the perfume composition and maintaining a transparent appearance.

[0048] It may be preferable to include PEG-40 hydrogenated castor oil in an amount of 0.1 to 1.0 weight% based on 100 weight% of the total perfume composition.

[0049] If the PEG-40 hydrogenated castor oil is less than 0.1 weight%, the solubilizing effect is insufficient, so the fragrance mixture may not be uniformly dispersed, and cloudiness or phase separation may occur. On the other hand, if it exceeds 1.0 weight%, spreadability may be reduced and the fragrance may be dulled due to excessive use. Therefore, the above range is a critical range to simultaneously ensure solubilizing stability and usability.

[0050] In one embodiment, 1,2-hexanediol acts as a hypoallergenic preservative to inhibit microbial growth, thereby ensuring the preservative stability of the perfume composition, while simultaneously performing a moisturizing auxiliary function.

[0051] It may be preferable to include 1,2-hexanediol in an amount of 0.1 to 1.0 weight% based on 100 weight% of the total perfume composition.

[0052] If 1,2-hexanediol is less than 0.1 weight%, the preservative effect is insufficient, which may reduce long-term storage stability. On the other hand, if it exceeds 1.0 weight%, the possibility of skin irritation may increase. Therefore, the above range is a critical range that simultaneously satisfies preservative stability and skin low irritation.

[0053] In one embodiment, tocopheryl acetate (vitamin E acetate) acts as an antioxidant to inhibit the oxidation of fragrance components by oxygen and light, thereby preventing the fragrance from deteriorating or discoloring, and performs a skin conditioning function.

[0054] It may be preferable to include tocopheryl acetate in an amount of 0.1 to 1.0 weight% based on 100 weight% of the total perfume composition.

[0055] If the tocopheryl acetate content is less than 0.1% by weight, the antioxidant effect is insufficient, so the effect of inhibiting fragrance deterioration is not sufficiently expressed. On the other hand, if it exceeds 1.0% by weight, stickiness may occur due to excessive use and manufacturing costs may increase. Therefore, the above range is a critical range that simultaneously satisfies both the antioxidant effect and the user experience.

[0056] In one embodiment, one or more of the musk-based fragrances and woody-amber-based fragrances among the fragrance mixture may be encapsulated in the form of nanocapsules using a cyclodextrin inclusion complex or phospholipids and included in the fragrance composition. When base note fragrances with a slow volatilization rate are encapsulated, the fragrance composition exhibits a controlled-release behavior in which the fragrance component is slowly released from the capsule after the alcohol volatilizes following application to the skin, thereby further enhancing fragrance persistence.

[0057] In one embodiment, the cyclodextrin inclusion may be formed by including beta-cyclodextrin (β) and a base note fragrance, and the duration of the lingering scent after application to the skin may be improved compared to the case where the fragrance is simply mixed without inclusion.

[0058] In addition, in one embodiment, the perfume composition according to the present disclosure may further contain 0.1 to 1 weight part of an anti-stress essential oil relative to 100 weight parts of the perfume base. When the anti-stress essential oil is further contained as described above, a functional perfume can be provided that not only has excellent palatability due to the scent but also reduces stress and exhibits antibacterial function.

[0059] At this time, it is preferable that the above anti-stress essential oil consists of one or more selected from the group consisting of cypress essential oil, Torreya essential oil, and bergamot essential oil. The essential oil component contained in the above cypress essential oil can play a role in lowering the cortisol index, a stress hormone, and can exhibit an antibacterial function that selectively sterilizes bacteria harmful to the human body. If the content of the above anti-stress essential oil is less than 0.1 parts by weight, the above effect is negligible, and if it exceeds 1 part by weight, the above effect is not significantly improved, and the preference of the perfume may decrease.

[0060] In one embodiment, the perfume composition may be formulated such that the total content of the labeled fragrance allergen component is 0.1% by weight or less with respect to 100% by weight of the entire perfume composition. The labeled fragrance allergen component refers to a fragrance component classified as potentially allergenic according to, for example, EU cosmetic regulations or IFRA standards. Since the fragrance mixture of the present disclosure uses synthetic musk fragrance and synthetic amber fragrance as main components to maintain a low content of fragrance allergens, a perfume composition with improved skin hypoallergenicity can be provided by reducing the potential for skin allergy induction while maintaining the target woody-amber-musk scent profile.

[0061] In one embodiment, the flavor allergen component to be labeled may include one or more selected from linalool, limonene, citral, geraniol, coumarin, eugenol, farnesol, benzyl alcohol, benzyl benzoate, benzyl salicylate, citronellol, cinnamal, hydroxycitronellal, isoeugenol, and anise alcohol, but is not limited thereto.

[0062] In one embodiment, the perfume composition may be formulated such that the total content of the labeled fragrance allergen component is 0.1% by weight or less, preferably 0.08% by weight or less, and more preferably 0.05% by weight or less. At this time, the total content of the labeled fragrance allergen component may be calculated as the sum of the values ​​obtained by converting the content of each fragrance allergen component included in the fragrance mixture into 100% by weight of the total perfume composition.

[0063] In one embodiment, the perfume composition may keep the content of the labeled fragrance allergen component low by limiting the amount of natural essential oil or natural floral absolute and increasing the proportion of synthetic musk-based fragrances and synthetic woody-amber-based fragrances. For example, the perfume composition may use habanolide, exaltolide, iso-i super, cetalox, tris amber, ambroxan, and ambergris T as the main base fragrance components and limit the content of auxiliary fragrances that may contain labeled fragrance allergen components such as linalool, limonene, citral, geraniol, coumarin, and eugenol.

[0064] In one embodiment, even if the perfume composition includes a naturally derived floral fragrance such as jasmine sambac absolute, by limiting the content of the naturally derived floral fragrance to 2 to 6 weight percent based on 100 weight percent of the total fragrance mixture, it is possible to suppress an increase in the total amount of the labeled fragrance allergen component while maintaining the natural and diffusive nature of the floral scent.

[0065] In one embodiment, when the total content of the labeled fragrance allergen component is controlled to 0.1 weight% or less, the potential for allergy-inducing or irritation upon skin application can be reduced while maintaining the target woody-amber-musk scent profile. Additionally, even if the fragrance composition contains a high concentration of fragrance mixture, the total amount of fragrance allergen component is limited, which improves the user experience after application and alleviates the burden of use for users with sensitive skin.

[0066] In one embodiment, the content of the fragrance allergen component to be labeled can be measured using gas chromatography-mass spectrometry (GC-MS), gas chromatography-flame ionization detection (GC-FID), or an equivalent analysis method. Based on the analysis results, by adjusting the type or content of auxiliary fragrances included in the fragrance mixture, the total content of the fragrance allergen component to be labeled can be controlled to 0.1% by weight or less relative to 100% by weight of the entire perfume composition.

[0067] <Preparation Example 1> Preparation of a fragrance mixture

[0068] 15 parts by weight of habanolide, 9 parts by weight of exaltolide, 18 parts by weight of iso-i super, 8 parts by weight of cetalox, 6 parts by weight of tris amber, 5 parts by weight of ambroxan, 4 parts by weight of ambergris T, 12 parts by weight of hedion, 4 parts by weight of jasmine sambac absolute, and 19 parts by weight of other auxiliary flavorings (citrus-based) were weighed and placed in a light-shielding container, stirred at a speed of 150 rpm for 30 minutes at 25°C, and then left to stand at 25°C for 24 hours to prepare a flavoring mixture. In the above fragrance mixture, the woody-amber fragrance (Iso-E Super, Cetalox, Tris Amber, Ambroxan, Ambergris T) is 41 parts by weight, the musk fragrance (Habanolide, Exaltolide) is 24 parts by weight, and the floral fragrance (Hedione, Jasmine Sambac Absolute) is 16 parts by weight, corresponding to about 58.5 parts by weight of musk fragrance and about 39 parts by weight of floral fragrance per 100 parts by weight of woody-amber fragrance.

[0073] <Preparation Example 4> Preparation of a base note fragrance inclusion

[0074] A saturated aqueous solution was prepared by dissolving beta-cyclodextrin in purified water, and base note fragrances (habanolide and ambroxan) were added dropwise at a ratio of 0.8 to 1.2 moles per mole of beta-cyclodextrin while stirring at 40°C at 500 to 1,000 rpm for 4 hours to induce an inclusion reaction. Subsequently, the resulting precipitate was filtered and recovered, and freeze-dried at -40°C to produce a powdered fragrance inclusion body. The inclusion body can be dispersed in a fragrance mixture and applied to a perfume composition.

[0075] <Preparation Example 5> Preparation of anti-stress essential oil

[0076] The leaves and stems of the cypress tree were cut into pieces 2 to 3 cm in length and placed into a steam distillation apparatus. The resulting gas was steam distilled at 95 to 105°C for 4 to 6 hours, cooled through a cooling tube, and then the water layer and oil layer were separated. The separated oil layer was filtered to produce cypress essential oil.

[0102] <Experimental Example 1> Scent Preference Evaluation

[0103] Fragrance preference was evaluated for the perfume compositions prepared through Examples 1 to 4 and Comparative Examples 1 to 4 above. For 100 subjects, each perfume composition was sprayed onto a scent strip, and the overall preference for the fragrance was evaluated using a 5-point scale and expressed as the average value (5 points: Very good, 4 points: Good, 3 points: Average, 2 points: Poor, 1 point: Very poor). The results are shown in [Table 1] below.

[0104] division Preference (5 points) Example 1 4.6 Example 2 4.4 Example 3 4.5 Example 4 4.4 Comparative Example 1 3.6 Comparative Example 2 3.7 Comparative Example 3 3.5 Comparative Example 4 3.8

[0105] As shown in [Table 1] above, Examples 1 to 4 of the present disclosure exhibited excellent fragrance preference, whereas Comparative Example 1, which had an excessive proportion of woody-amber fragrance, had a heavy and dull fragrance, resulting in reduced preference, and Comparative Example 3, which had an excessive content of fragrance mixture, had an excessively strong fragrance, causing aversion and resulting in reduced preference. <Experimental Example 2> Evaluation of Fragrance Persistence

[0106] Fragrance persistence was evaluated for the perfume compositions prepared through Examples 1 to 4 and Comparative Examples 1 to 4. For 30 subjects, 0.1 mL of each perfume composition was sprayed onto the wrist, and the time until the scent was detected was measured and expressed as an average value (time). The results are shown in [Table 2] below.

[0107] division Scent duration (time) Example 1 8.5 Example 2 7.8 Example 3 8.8 Example 4 8.2 Comparative Example 1 7.9 Comparative Example 2 6.2 Comparative Example 3 8.9 Comparative Example 4 8.0

[0108] As shown in [Table 2] above, Examples 1 to 4 of the present disclosure exhibited excellent fragrance longevity, whereas Comparative Example 2, which had an excessive proportion of floral fragrances, showed a significantly reduced fragrance duration as the scent dissipated rapidly due to an excessive proportion of highly volatile middle notes. Meanwhile, although Comparative Example 3 had a long fragrance duration due to its excessive fragrance content, its preference was lowered due to odor aversion, as shown in [Table 1] above. <Experimental Example 3> Skin Irritation Evaluation

[0109] Skin irritation was evaluated for the perfume compositions prepared through Examples 1 to 4 and Comparative Examples 1 to 4 above. Skin irritation was measured using a 3-point scale after using each perfume composition for 10 days on 100 subjects, and the result was expressed as the average value (3 points: no irritation, 2 points: slight irritation, 1 point: very irritation). The results are shown in [Table 3] below.

[0110] division Skin irritation (3 points) Example 1 2.9 Example 2 2.9 Example 3 2.7 Example 4 2.8 Comparative Example 1 2.8 Comparative Example 2 2.8 Comparative Example 3 2.4 Comparative Example 4 2.7

[0111] As shown in [Table 3] above, Examples 1 to 4 of the present disclosure showed low skin irritation, whereas Comparative Example 3, which contained an excessive amount of fragrance mixture, was found to have relatively high skin irritation. This is attributed to the fact that skin dryness and irritation caused by alcohol were alleviated by the inclusion of moisturizing and low-irritation ingredients, such as 1,3-butylene glycol and 1,2-hexanediol, in appropriate amounts. <Experimental Example 4> Evaluation of Long-term Storage Stability

[0112] The perfume compositions prepared through Examples 1 to 4 and Comparative Examples 1 to 4 were sealed and stored for 4 weeks each at room temperature (25°C), refrigerated (4°C), and high temperature (45°C), respectively. Afterward, the presence of cloudiness, phase separation, and deterioration of the scent were observed and are shown in [Table 4] below. Representative results of Example 1 and Comparative Examples 3 and 4 are shown together.

[0113] division Room temperature (25℃) Refrigeration (4℃) High temperature (45℃) Example 1 No issues No issues No issues Example 2 No issues No issues No issues Example 3 No issues No issues No issues Example 4 No issues No issues No issues Comparative Example 3 No issues No issues Change of smell (usually) Comparative Example 4 cloudy white No issues cloudiness / phase separation

[0114] As shown in [Table 4] above, Examples 1 to 4 of the present disclosure maintained a stable state without turbidity, phase separation, or fragrance degradation at room temperature, refrigeration, and high temperature. On the other hand, Comparative Example 4, which did not contain the solubilizing agent PEG-40 hydrogenated castor oil, exhibited turbidity and phase separation at both room temperature and high temperature, confirming that the proper formulation of the solubilizing agent is critical to the storage stability of the perfume composition. <Experimental Example 5> Evaluation of Sustained-Release Fragrance Durability

[0115] To evaluate sustained-release fragrance persistence following the encapsulation of base note fragrances, perfume compositions of Example 1 (without fragrance inclusions) and Example 5 (with fragrance inclusions) were compared. For 30 subjects, 0.1 mL of each perfume composition was sprayed onto the wrist, and the lingering scent intensity over time was evaluated using a 10-point scale and expressed as the average value. The results are shown in [Table 5] below.

[0116] division 1 hour 4 hours 8 hours 12 hours 24 hours Example 1 9.0 7.4 4.9 2.4 0.7 Example 5 8.4 7.7 6.6 4.7 2.5

[0117] As shown in [Table 5] above, Example 5, which applied a fragrance inclusion, had a slightly lower initial afterglow intensity compared to Example 1, which did not; however, after 8 hours, the afterglow intensity remained significantly higher, confirming that the controlled-release behavior resulting from the encapsulation of the base note fragrance improved fragrance persistence. Specifically, the afterglow intensity of Example 5 at the 8-hour mark was approximately 6.6, which was maintained at a level approximately 1.35 times higher than that of Example 1 (approximately 4.9). <Experimental Example 6> Evaluation of Stress Relief and Antimicrobial Activity

[0118] To evaluate the effects of adding anti-stress essential oils, the perfume compositions of Example 1 (which did not contain cypress essential oil) and Example 6 (which contained cypress essential oil) were compared. The stress-relieving effect was evaluated on 50 subjects using a 5-point scale to assess the degree of subjective stress relief after use (5 points: very good, 1 point: very poor), and the antibacterial activity was measured by the disc diffusion method to determine the zone of inhibition (mm) for Staphylococcus aureus and Escherichia coli. The results are shown in [Table 6] below.

[0119] division Stress relief (5 points) Staphylococcus aureus inhibition zone (mm) E. coli inhibition zone (mm) Example 1 3.2 0 0 Example 6 4.5 11.2 8.4

[0120] As shown in [Table 6] above, Example 6, containing cypress essential oil, showed significantly superior stress relief evaluation compared to Example 1, and it was confirmed that antibacterial activity was expressed by exhibiting zones of growth inhibition against Staphylococcus aureus and Escherichia coli. This implies that the fragrance composition of the present disclosure can simultaneously provide not only preference based on scent but also stress relief and antibacterial functions. <Experimental Example 7> Evaluation of Skin Hypoallergenicity (Reduction of Fragrance Allergens)

[0121] To evaluate skin hypoallergenicity according to the content of the labeled fragrance allergen ingredients, a human patch test was performed on the fragrance compositions of Example 7, with a total fragrance allergen content of 0.08 wt%, and Comparative Example 5, with a total fragrance allergen content of 0.45 wt%. Each fragrance composition was applied to the back of 30 subjects, and after 48 hours, the patch test positive rate (%) and skin irritation index were measured and are shown in [Table 7] below.

[0122] division Total flavor allergens (weight%) Patch test positive rate (%) Skin irritation index Example 7 0.08 1.0 0.3 Comparative Example 5 0.45 8.0 1.1

[0123] As shown in [Table 7] above, Example 7, in which the total content of the labeled fragrance allergen component was controlled to 0.1 weight% or less, showed a significantly lower patch test positive rate and skin irritation index compared to Comparative Example 5. This means that the woody-amber-musk accordion of the present disclosure can maintain a low content of fragrance allergens by using synthetic musk fragrance and synthetic amber fragrance as main components, thereby ensuring low skin irritation while maintaining the target fragrance notes.

[0124] In this specification, fragrance persistence can be quantitatively evaluated by applying 0.1 mL of a fragrance composition to a substrate, maintaining it at 32 ± 1°C, collecting headspace gas after a certain period of time has elapsed since application, analyzing it by gas chromatography-mass spectrometry (GC-MS), and measuring the total peak area of ​​the detected fragrance component. A fragrance composition containing the same fragrance in the form of a cyclodextrin inclusion may maintain a higher residual fragrance peak area after 8 hours of application compared to a fragrance composition containing the fragrance in a free state without inclusion.

[0125] <Experimental Example 8> Evaluation of Fragrance Persistence Using Headspace GC-MS

[0126] To objectively evaluate the fragrance persistence resulting from the application of cyclodextrin inclusions, headspace GC-MS analysis was performed on the fragrance compositions of Example 1, which contained unincorporated fragrances, and Example 5, which contained base note fragrances (habanolide and ambroxan) in the form of cyclodextrin inclusions. Specifically, 0.1 mL of each fragrance composition was applied to a substrate and maintained at 32±1℃; a certain volume of headspace gas was collected at 1, 2, 4, 8, 12, and 24 hours after application and analyzed by GC-MS, and the total peak area of ​​the detected fragrance components was measured. The measured values ​​were converted into relative values ​​with the peak area at 1 hour of Example 1 set to 100, and the results are shown in [Table 8] and Figure 2 below.

[0127] Time elapsed since application (hours) Example 1 (unprotected) Example 5 (Inclusion) 1 100 89 2 75 77 4 48 60 8 27 37 12 12 24 24 4 10

[0128] As shown in [Table 8] and Figure 2 above, at the beginning of application (1 hour), the headspace fragrance peak area of ​​Example 1 containing the unencapsulated fragrance was higher, but from the point after 4 hours, the peak area of ​​Example 5 containing the cyclodextrin inclusion was maintained at a higher level. In particular, at the point after 8 hours, the residual fragrance peak area (37) of Example 5 was approximately 1.37 times that of Example 1 (27), confirming that the controlled-release release by the cyclodextrin inclusion significantly improved fragrance persistence. This is because the unencapsulated fragrance rapidly volatilizes and disappears at the beginning of application, whereas the fragrance encapsulated within the molecular cavity is slowly released from the molecular cavity after the denatured ethanol volatilizes.

[0129] According to one embodiment of the present disclosure, a perfume composition comprises, based on 100 weight% of the total perfume composition, 75 to 84 weight% of denatured ethanol; 15 to 20 weight% of a fragrance mixture; 0.5 to 1.5 weight% of 1,3-butylene glycol; 0.1 to 1.0 weight% of PEG-40 hydrogenated castor oil; and 0.1 to 1.0 weight% of 1,2-hexanediol. and 0.1 to 1.0 weight% of tocopheryl acetate, and the fragrance mixture comprises a musk-based fragrance, a woody-amber-based fragrance, and a floral-based fragrance, wherein the musk-based fragrance comprises habanolide and exaltolide, the woody-amber-based fragrance comprises Iso E Super, Cetalox, Trisamber, Ambroxan, and Ambergris T, and the floral-based fragrance comprises Hedione and Jasmin Sambac Absolute, and the fragrance mixture may comprise 50 to 70 weight parts of the musk-based fragrance and 30 to 45 weight parts of the floral-based fragrance per 100 weight parts of the woody-amber-based fragrance.

[0130] In one embodiment, the fragrance mixture comprises, based on 100 weight% of the total fragrance mixture, 13 to 17 weight% habanolide; 7 to 11 weight% exaltolide; 16 to 20 weight% iso-i super; 6 to 10 weight% cetalox; 4 to 8 weight% trisamber; 3 to 7 weight% ambroxan; 2 to 6 weight% ambergris T; 10 to 14 weight% hedione; and 2 to 6 weight% jasmine sambac absolute. It includes other auxiliary fragrances, wherein the other auxiliary fragrances are included as the remainder excluding the total content of habanolide, exaltolide, iso-i super, cetalox, tris amber, ambroxan, ambergris T, hedion, and jasmine sambac absolute from 100 weight% of the total fragrance mixture, and the other auxiliary fragrances may be at least one of citrus fragrances, green fragrances, and spicy fragrances.

[0131] In one embodiment, at least one of the musk-based fragrance and the woody-amber-based fragrance is dispersed and contained in the perfume composition in the form of a powdered cyclodextrin inclusion enclosed within a molecular cavity of beta-cyclodextrin, and the enclosed fragrance is retained within the molecular cavity before the denatured ethanol volatilizes when the perfume composition is applied to the skin, and is released from the molecular cavity after the denatured ethanol volatilizes, and the perfume composition may have a residual fragrance intensity at least 1.3 times that of a perfume composition configured identically except that it contains an equal weight of non-enclosed fragrance instead of the cyclodextrin inclusion at the time of application to the skin after 8 hours.

[0132] Specifically, at least one of the musk-based fragrance and the woody-amber-based fragrance may be dispersed and contained in the perfume composition in the form of a powdered cyclodextrin inclusion enclosed within the molecular cavity of beta-cyclodextrin (β).

[0133] The above-mentioned beta-cyclodextrin has a cyclic oligosaccharide structure in which a plurality of glucose units are connected in a ring shape, and forms a truncated cone molecular cavity in the center thereof. The interior of the molecular cavity exhibits a hydrophobic environment, while the exterior exhibits a hydrophilic environment. Accordingly, one or more molecules of the oil-soluble fragrance components forming the base note of the present disclosure, such as musk-based fragrances (habanolide, exaltolide) and woody-amber-based fragrances (iso-i super, cetalox, tris amber, ambroxan, ambergris T), can be physically captured within the hydrophobic molecular cavity to form a stable host-guest inclusion.

[0134] The fragrance in the form of the above inclusion is stably maintained within the molecular cavity before the denatured ethanol volatilizes when the perfume composition is applied to the skin (initial application stage), thereby controlling rapid initial volatilization. Subsequently, after the denatured ethanol volatilizes, the fragrance molecules effectively dissociate from the molecular cavity due to external stimuli such as body temperature, minute moisture (sweat), and friction, exhibiting a controlled-release behavior in which they are gradually released to the outside. Through this, rapid loss of the fragrance within the specific solubilized base of the present disclosure is prevented, and the persistence of the lingering scent can be maximized.

[0135] The effect of enhancing sustained-release fragrance persistence by the above-mentioned cyclodextrin inclusion can be objectively quantified through headspace GC-MS (Gas Chromatography-Mass Spectrometry) analysis. The headspace GC-MS analysis is a method of capturing and analyzing volatile fragrance components present in a sealed gas space (headspace) above the skin environment where the fragrance composition is applied, and is directly proportional to the fragrance intensity and lingering scent density perceived by the actual user in the environment. For example, the quantification can be performed by setting a key lingering scent substance, such as ambroxan, one of the woody-amber fragrances of the present disclosure, or habanolide, a musk fragrance, as a marker compound. When the headspace gas collected 8 hours after application to the skin is injected into gas chromatography (GC), the indicator component separated by passing through the capillary column is detected as a molecular ion peak with a unique mass-to-charge ratio (m / z) through a mass spectrometer (MS).

[0136] At this time, the amount of fragrance components remaining in the gas is quantified by integrating the Area Under the Curve (AUC) of the retention time of the corresponding indicator component on the extracted ion chromatogram. That is, since the fragrance composition to which the cyclodextrin inclusion is applied continues to volatilize at a certain level or higher even after 8 hours due to delayed release within the molecular cavity, the integrated peak area is calculated to be significantly larger than 1.3 times compared to a simple mixed control group that is not encapsulated, thereby objectively proving the effect of improving sustained-release fragrance persistence.

[0137] The fragrance composition according to the present disclosure exhibits a total peak area of ​​residual fragrance components measured by headspace GC-MS analysis at 8 hours after application to the skin that is at least 1.3 times, preferably at least 1.35 times, compared to the peak area of ​​a control fragrance composition configured identically except that it contains an equal weight of non-enclosed fragrance instead of the cyclodextrin inclusion. If the ratio of residual peak area at the 8-hour mark is less than 1.3 times, the formation efficiency of the inclusion is insufficient or it is difficult to achieve the target sustained-release control effect, making it impossible to maintain long-lasting scent persistence. Therefore, the limiting value of a headspace GC-MS peak area ratio of at least 1.3 times is an indicator proving that critical significance for scent persistence has been achieved through the combination of the specific fragrance mixture and inclusion technology of the present disclosure.

[0138] In this specification, the term 'peak area of ​​residual fragrance components' refers to the value obtained by integrating and summing the areas of peaks corresponding to fragrance-derived components detected in the total ion chromatogram (TIC) obtained from the headspace GC-MS analysis. In one embodiment, the peak area of ​​the residual fragrance components may be measured as the sum of the peak areas corresponding to base note fragrances contained in the fragrance mixture in the form of cyclodextrin inclusions, namely habanolide and ambroxane. In this case, since the residual amount of the fragrance component subjected to inclusion treatment is directly measured, the sustained-release effect by the inclusion can be quantified more clearly.

[0139] The above headspace GC-MS analysis may be performed, for example, under the following conditions. A substrate coated with 0.1 mL of a fragrance composition is placed in a sealed vial and equilibrated at 32 ± 1°C for 30 minutes, after which 1 mL of headspace gas is collected and injected. A non-polar capillary column (e.g., 5% phenyl-95% dimethylpolysiloxane, 30 m × 0.25 mm, membrane thickness 0.25 μm) is used as the column, and helium is flowed as the carrier gas at a flow rate of 1.0 mL / min. The oven temperature is maintained at 50°C for 2 minutes and then increased to 280°C at a rate of 10°C per minute. The mass spectrometer scans the range of m / z 35 to 400 using electron impact ionization (EI, 70 eV). However, the above analysis conditions are exemplary, and other conditions may be employed as long as the fragrance components can be separated and detected.

[0140] At this time, the two perfume compositions to be compared, namely a perfume composition containing a cyclodextrin inclusion and a perfume composition containing an equal weight of a non-inclusion fragrance, are measured under the same analytical conditions, and the ratio of the peak areas is calculated as a relative ratio between the values ​​measured under the same conditions. Therefore, the figure of 1.3 times can be evaluated reproducibly without relying on the absolute values ​​of the analytical device and measurement conditions.

[0142] In one embodiment, the cyclodextrin inclusion body may be manufactured by a manufacturing method comprising the steps of: adding one or more of the musk-based fragrance and the woody-amber-based fragrance to an aqueous solution of beta-cyclodextrin in a ratio of 0.8 to 1.2 moles per mole of beta-cyclodextrin and stirring at 30 to 50°C to induce an inclusion reaction; and recovering and drying the generated precipitate.

[0143] In one embodiment, the total content of the fragrance allergen component of the fragrance composition may be 0.1% by weight or less with respect to 100% by weight of the entire fragrance composition.

[0144] In one embodiment, a method for preparing the perfume composition comprises the steps of: preparing a perfume base by mixing 1,3-butylene glycol, PEG-40 hydrogenated castor oil, 1,2-hexanediol, and tocopheryl acetate with denatured ethanol; mixing the fragrance mixture into the perfume base; aging the mixture containing the fragrance mixture at 3 to 10°C for 7 to 30 days; and filtering the aged mixture, wherein the filtration step may include filtering the aged mixture with a 0.45 μm filter.

[0145] Meanwhile, the perfume composition according to the present invention may be prepared by a manufacturing method comprising: (a) a step of preparing a perfume base; (b) a step of mixing a fragrance mixture with the perfume base; (c) a step of aging the mixture in which the fragrance mixture is mixed; and (d) a step of filtering the aged mixture.

[0146] First, the step of (a) preparing the perfume base is to prepare a uniform perfume base by adding 1,3-butylene glycol, PEG-40 hydrogenated castor oil, 1,2-hexanediol, and tocopheryl acetate to denatured ethanol and stirring. At this time, it is preferable that the stirring be performed at room temperature (20 to 25°C) at a speed of 200 to 500 rpm for 10 to 30 minutes. The PEG-40 hydrogenated castor oil acts as a solubilizer and is dissolved in the denatured ethanol before the addition of the fragrance mixture, thereby uniformly solubilizing the fragrance mixture added thereafter, which can suppress cloudiness and phase separation of the perfume composition.

[0147] Next, the step of mixing the fragrance mixture (b) is a step of preparing a mixture by slowly adding the fragrance mixture to the perfume base while stirring. It is preferable that the stirring be performed at room temperature at a speed of 150 to 300 rpm for 10 to 40 minutes, thereby ensuring that the fragrance mixture is uniformly dispersed within the perfume base. In one embodiment, one or more of the musk-based fragrances and woody-amber-based fragrances among the fragrance mixture may be added in the mixing step in the form of cyclodextrin inclusions.

[0148] Next, the maceration step (c) above involves placing the mixture in a sealed container and macering it at 3 to 10°C for 7 to 30 days. During the maceration process, the fragrance components blend together within the perfume base, stabilizing the balance of the scent and mitigating the initial raw note, thereby improving the palatability of the scent. If the maceration temperature is less than 3°C or the maceration time is less than 7 days, the scent stabilization effect is not sufficiently manifested; conversely, if the maceration temperature exceeds 10°C or the maceration time exceeds 30 days, the volatilization and deterioration of the fragrance components are accelerated, which may actually lead to a decrease in the scent. Therefore, the maceration conditions represent a critical range that simultaneously satisfies both scent stabilization and fragrance preservation.

[0149] Finally, the filtration step (d) above is a step of filtering the aged mixture to remove precipitates and impurities. Preferably, the filtration is performed using a 0.45 μm filter, and through this, fine precipitates and insoluble wax components that may be generated during the aging process are removed, thereby obtaining a perfume composition that is transparent, has a uniform appearance, and has excellent storage stability.

[0150] The perfume composition prepared by the manufacturing method comprising steps (a) to (d) above has high fragrance preference, excellent fragrance persistence, low skin irritation, and excellent long-term storage stability.
