Description

fragrance composition

[0001] The present invention relates to a fragrance composition and a method for perfume application.

[0002] BACKGROUND ART Fragrances are used in various everyday products to impart a sense of luxury, a sense of security, and a sense of anticipation for effectiveness. Distinctive scents have the effect of distinguishing products and attracting customers. In general, fragrances are added to products using fragrance compositions that contain a mixture of multiple fragrance materials in order to control the balance and persistence of the scent. Fragrances are also often used in detergents and fabric softeners used to treat textile products such as clothing, in order to impart fragrance to the textile products after treatment.

[0003] For example, JP-A No. 2008-517051 describes an oil-containing composition containing oil, a predetermined surfactant system, a predetermined solubilization aid, and water under predetermined conditions, and lists a fragrance as the oil. JP-A No. 2009-261929 describes a transparent fragrance liquid containing a fragrance and a surfactant, in which the surfactant is contained in a ratio of 0.4 to 1 part by weight per 1 part by weight of the fragrance.

[0004] SUMMARY OF THE INVENTION The present invention provides a fragrance composition and a method for imparting fragrance that have excellent lingering fragrance to an object.

[0005] The present invention relates to a fragrance composition containing (A) a fragrance compound (hereinafter referred to as component (A)) and (B) a compound represented by the following formula 1 (hereinafter referred to as component (B)):

[0006]

[0007] [In the formula, R １ and R ２ are each a hydrocarbon group, and R １ and R ２ The total number of carbon atoms in A is 17 or more, １ O and A ２ O is A, respectively. １ and A ２ is an alkyleneoxy group having 2 to 4 carbon atoms and having the alkylene group, １ O and A ２and M is the average number of moles of O added, each of which is a number of 0 to 10, and M is a cation.

[0008] The present invention also relates to a method for perfume application, in which an object is treated with the fragrance composition of the present invention.

[0009] According to the present invention, a fragrance composition and a method for imparting fragrance that have excellent lingering fragrance on an object are provided.

[0010] Modes for Carrying Out the Invention [Fragrance Composition] Component (A) is a fragrance compound. From the viewpoint of dispersion stability and fragrance retention, the Log P of component (A) is preferably 1 or more, more preferably 2 or more, even more preferably 3 or more, and preferably 7 or less, more preferably 5 or less, and even more preferably 4 or less. Here, Log P is the logarithm of the 1-octanol / water partition coefficient of the compound, and means the ratio of the equilibrium concentrations of the solute in each solvent at partition equilibrium when the compound is dissolved as a solute in a two-phase solvent system of 1-octanol and water, and is generally expressed in the form of a logarithm to the base 10, "log P." That is, the log P value is an index of lipophilicity (hydrophobicity); the larger this value, the more hydrophobic it is, and the smaller the value, the more hydrophilic it is. Log P can be calculated, for example, from Daylight Chemical Information Systems, Inc. LogP values ​​for many compounds are listed in databases available from, for example, Daylight CIS, and can be referenced. Furthermore, if no measured LogP values ​​are available, they can be calculated using programs such as "CLOGP" (Daylight CIS), and among these, calculations using the "CLOGP" program are highly reliable and preferred. In the "CLOGP" program, the "calculated LogP (sometimes referred to as CLogP)" value calculated using the Hansch and Leo fragment approach is output together with the measured LogP value, if available. The fragment approach is based on the chemical structure of a compound, taking into account the number of atoms and the type of chemical bond (A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990). Since this CLogP value is currently the most common and reliable estimate, it is preferable to use the CLogP value instead when selecting a compound if an actual LogP value is not available. In the present invention, either the actual LogP value or the CLogP calculated by the program "CLOGP" may be used as the LogP of component (A).

[0036] Component (B) is a compound represented by the above formula 1. The reason why the use of component (B) in combination with component (A) improves fragrance retention is unclear, but the present inventors speculate as follows: The fragrance composition of the present invention is typically applied to a target object, such as fabric, in the presence of water, for example, by blending it in a treatment liquid containing water. When component (A) and component (B) coexist in water, component (B) forms a vesicle with a structure that solubilizes component (A). These vesicles adsorb to the target object and promote dehydration, thereby suppressing the volatilization of component (A), which volatilizes along with water. Furthermore, the presence of component (A) in the vesicle also contributes to the suppression of volatilization of component (A). In other words, component (B) is thought to have an excellent effect of delivering component (A) to a target object in water. These factors are thought to suppress the volatilization of component (A), improving fragrance retention. However, the mechanism of action of the present invention is not limited to this.

In the present invention, the fragrance composition of the present invention can be applied to the fibers in any of these washing processes so that the component (B) is present in a predetermined amount.

[0076] The component (B) of the present invention is believed to have excellent delivery effects for the component (A), and is particularly effective in improving the degree of delivery of the component (A) when delivering the component (A) to a target object such as a fiber in an aqueous system. For example, the present invention provides a method for improving the delivery of the component (A), in which the component (B) is used in combination with the component (A) when delivering the component (A) to a target object in the presence of water, thereby improving the delivery of the component (A) to the target object. The component (B) may be, for example, a fragrance enhancer for the fragrance compound (A).

[0077] Examples <Example 1 and Comparative Example 1> (1) Pretreatment of Towels for Evaluation Towels were used for evaluation after removing starch and impurities through the following pretreatment. Using a fully automatic washing machine (Panasonic, model number: NA-F60PB3), 24 sheets of commercially available cotton towels (TW220, white, manufactured by Yoshikawa Towel Co., Ltd.) or synthetic fiber towels (YUI, gray / brown, 85% polyester / 15% nylon) were washed three times with 52.22 g of a 10% diluted solution of a nonionic surfactant (Emulgen 108, manufactured by Kao Corporation) as detergent, using tap water from Wakayama City as the water (50 L of water, 10 minutes of washing, two rinses, and 9 minutes of spin drying). The same washing process was then repeated twice using water alone. The towels were then left to dry naturally at room temperature (25°C) for 24 hours.

[0078] (2) Towel Treatment Method: A predetermined amount of ion-exchanged water (bath ratio 20 kg / kg towel) was placed in a portable washing machine (National, Model No.: NA-35), and a calcium chloride aqueous solution (equivalent to 4000°DH) was added so that the treatment solution had a hardness shown in Table 1. A 5% by weight aqueous dispersion of a fragrance composition shown in Table 1 was then added with stirring to the treatment solution so that the concentration of component (B) reached the treatment concentration (% owf) shown in Table 1. The treatment solution was then prepared by stirring for 1 minute. Two towels (totaling approximately 140 g) pretreated as described in (1) above were then placed in the washing machine and treated for 3 minutes with stirring. The towels were then dehydrated for 2 minutes in the spin tub of a two-tier washing machine (TOSHIBA, Model No.: VH-52G(H)) and dried in a room at 23°C / 45% RH. The treatment solution prepared here also constitutes a fragrance composition.

[0079] (3) Evaluation of Fragrance Lingering (3-1) Evaluation 1 (Fragrance Lingering by Paired Evaluation) For the towels treated in (2), four fragrance expert panelists evaluated the fragrance lingering 8 hours and 24 hours after spin-drying. In each case, towels from the Example and Comparative Examples in the same test group and at the same elapsed time after spin-drying were compared. If there was a difference in fragrance intensity, the stronger one was given 3 points and the weaker one was given 1 point. If the fragrance intensity was the same, each was given 2 points, and the total scores of the four panelists were calculated. The evaluation results are shown in Table 1.

[0080] (3-2) Evaluation 2 (Fragrance Lingering by Additive Evaluation) For the towels treated in (2), four fragrance expert panelists evaluated the fragrance lingering 4 hours and 24 hours after dehydration using the following evaluation criteria. The evaluation scores of the four panelists for towels in the same test group after the same time period were totaled. In this case, it was permitted to assign evaluation scores to one decimal place with reference to the evaluation criteria below. For each evaluation, the total evaluation score after 24 hours was divided by the total evaluation score after 4 hours to obtain the fragrance lingering 24 hours after dehydration (fragrance lingering A in the table) based on the 4 hours after dehydration. （２４／４） The evaluation results are shown in Table 1. (Evaluation criteria) 0: No scent 1: Scent that can barely be detected (detection threshold) 2: Weak scent that can be identified (recognition threshold) 3: Scent that can be easily detected 4: Strong scent 5: Extremely strong scent The higher the score, the stronger the scent and the greater the lingering effect.

[0081]

[0082] In each test group in Table 1, when the fragrance composition of the Example was used, higher fragrance lingering was observed 8 hours and 24 hours after dehydration than when the fragrance composition of the Comparative Example was used, as shown in Evaluation 1. Furthermore, when the fragrance composition of the Example was used in each test group in Table 1, higher fragrance lingering was observed 8 hours and 24 hours after dehydration, as shown in Evaluation 2. （２４／４） Since the value is larger than that of the comparative example, it can be seen that the effect of maintaining the fragrance lingering over time is better. It was confirmed that component (A) alone is insoluble or poorly soluble in water, but when used in combination with component (B) in the example or component (B') in the comparative example, component (A) was solubilized. Furthermore, since the fibers were scented by treating them with the fragrance composition as described above, it is believed that component (A) was adsorbed onto the fibers. Furthermore, since a higher fragrance lingering was obtained when component (B) was used than when component (B') was used, it is believed that component (B) has a higher delivery effect for component (A) than component (B'). In this way, component (B) more effectively transports component (A) to the target object, such as fibers, and the function and effect of component (A) are manifested in the target object.

[0083] Example 2 and Comparative Example 2 (1) Pretreatment of Evaluation Fabrics The fabrics used for evaluation were pretreated to remove starch and impurities as follows. Using a fully automatic washing machine (Panasonic, Model No. NA-F60PB3), 1.8 kg of cotton knitted fabric (manufactured by Shikisen Co., Ltd., cotton knitted fabric, listed as cotton fabric in Table 2) or polyester jersey fabric (manufactured by Tanigashira Shoten, Dyeing Test Materials Co., Ltd., listed as synthetic fabric in Table 2) was washed twice using a 45 L water volume, 10-minute wash, two rinses, and a 9-minute spin cycle. The same washing cycle was then repeated three times using water only. The fabrics were then left to air dry at room temperature (25°C) for 24 hours, and then cut into 6 cm x 6 cm squares to prepare test fabrics.

[0084] (2) Method of treating test cloth A treatment solution was prepared by diluting a 5% by mass aqueous dispersion of the fragrance composition shown in Table 2 with an aqueous calcium chloride solution (corresponding to 4°DH) so that the concentration of component (B) became the concentration shown in Table 2. The treatment solution was added dropwise to the test cloth treated in (1) in the mass ratio shown in Table 2, and the cloth was dried in a room at 23°C / 35%RH.

[0085] (3) Evaluation of Fragrance Lingering (3-1) Evaluation 1 (Fragrance Lingering by Paired Evaluation) The test cloths treated in (2) were evaluated for fragrance lingering 6 hours and 24 hours after the treatment liquid was dripped on them by four fragrance expert panelists. Test cloths from the Example and Comparative Examples were compared for the same test group after the same time had elapsed. If there was a difference in fragrance intensity, the stronger one was given 3 points and the weaker one was given 1 point. If the fragrance intensities were the same, each was given 2 points, and the total score of the four panelists' evaluations was calculated. The evaluation results are shown in Table 2.

[0086] (3-2) Evaluation 2 (Fragrance Lingering by Additive Evaluation) The test cloths treated in (2) were evaluated for fragrance lingering 6 hours and 24 hours after the treatment liquid was dropped by four fragrance expert panelists according to the following evaluation criteria. The evaluation scores of the four panelists for the test cloths in the same test group after the same time period were totaled. In this case, it was permitted to assign evaluation points to one decimal place with reference to the following evaluation criteria. The total evaluation score after 24 hours was divided by the total evaluation score after 6 hours to obtain the fragrance lingering score 24 hours after dehydration (fragrance lingering score B in the table) based on the standard score of 6 hours after dehydration. （２４／６） The evaluation results are shown in Table 2. (Evaluation criteria) 0: No scent 1: Scent that can barely be detected (detection threshold) 2: Weak scent that can be identified (recognition threshold) 3: Scent that can be easily detected 4: Strong scent 5: Extremely strong scent The higher the score, the stronger the scent and the greater the lingering effect.

[0087]

[0088] In Table 2, when the fragrance compositions of the Examples were used, superior results were obtained in both Evaluation 1 and Evaluation 2 compared to the Comparative Examples, and it can be seen that even when the treatment method of Table 2, which is different from that of Table 1, was used, the Examples exhibited high fragrance retention.

[0089] Example 3 and Comparative Example 3 (1) Test Method: A 5% by mass aqueous dispersion of the fragrance composition shown in Table 3 was diluted with a calcium chloride aqueous solution (equivalent to 4°DH) so that the concentration of component (B) was the concentration shown in Table 3 to prepare a liquid for evaluation. 80 ml of the liquid for evaluation was placed in a standard bottle No. 11 (AS ONE, 5-130-07), and a roll of kitchen paper (Elleair, super absorbent kitchen towel, 12 cm x 12 cm) was placed upright in the bottle. At this time, the bottom of the paper was immersed in the liquid, and the top was exposed above the liquid surface. The sample was then left in a room at 23°C / 35% RH.

[0090] (2) Evaluation of Fragrance Lingering (2-1) Evaluation 1 (Fragrance Lingering by Paired Evaluation) For the evaluation liquids in (1), three fragrance expert panelists evaluated the fragrance lingering after 24 hours and 72 hours of standing. In each case, the test solutions of the Examples and Comparative Examples were compared for the same test group after the same amount of time had passed. If there was a difference in fragrance intensity, the stronger solution was given 3 points and the weaker solution was given 1 point. If the fragrance intensities were the same, each was given 2 points, and the total score of the three panelists' evaluations was calculated. The evaluation results are shown in Table 3.

[0091] (2-2) Evaluation 2 (Fragrance Lingering by Additive Evaluation) For the evaluation liquids in (1), three fragrance expert panelists evaluated the fragrance lingering after 24 hours and 72 hours of standing according to the following evaluation criteria. The evaluation scores of the three panelists for the test solutions in the same test group after the same time period were totaled. In this case, it was permitted to assign evaluation scores to one decimal place with reference to the following evaluation criteria. The total evaluation score after 72 hours was divided by the total evaluation score after 24 hours to obtain the fragrance lingering after 72 hours of standing (fragrance lingering C in the table) based on the fragrance lingering after 24 hours of standing. （７２／２４） The evaluation results are shown in Table 3. (Evaluation criteria) 0: No scent 1: Scent that can barely be detected (detection threshold) 2: Weak scent that can be identified (recognition threshold) 3: Scent that can be easily detected 4: Strong scent 5: Extremely strong scent The higher the score, the stronger the scent and the greater the lingering effect.

[0092]

[0093] In Table 3, when the fragrance compositions of the Examples were used, superior results were obtained in both Evaluation 1 and Evaluation 2 compared to the Comparative Examples, and it can be seen that the Examples exhibited high fragrance retention even in usage forms that take into consideration the evaporation of the fragrance composition into the air, such as in tabletop air fresheners.

[0094] The ingredients used in Tables 1 to 3 were as follows: Phenylethyl alcohol (Fujifilm Wako Pure Chemical Industries, Ltd., model number 168-00893, active ingredient content over 98.0%) Eugenol (Fujifilm Wako Pure Chemical Industries, Ltd., model number 057-03935, active ingredient content over 95.0%) Estragole (Sigma-Aldrich, model number A29208-25G, active ingredient content 98.0%) α-Hexyl cinnamaldehyde (Fujifilm Wako Pure Chemical Industries, Ltd., model number 088-04605, active ingredient content over 97.0%) Sodium di(2-propylheptyl) sulfosuccinate Sodium di(2-ethylhexyl) sulfosuccinate
