Description

TECHNICAL FIELD

[0001] The present application relates to a perfume composition and a perfume-imparting method. BACKGROUND

[0002] Perfumes are used for various products for daily use for the purpose of giving a sense of sophistication, a sense of security, a sense of expectation for effects, and the like. A characteristic fragrance imparts a product with a recognition effect, customer appeal. Generally, in order to control the balance, persistence, and the like of a fragrance, a perfume composition in which a plurality of perfume materials are mixed is used for perfume-imparting to a product.

[0003] In detergents, softening agents, and the like for treating fiber products such as laundry, a perfume is also often used for the purpose of perfume-imparting to the treated fiber products.

[0004] For example, in Japanese Patent Application Laid-Open No. 2008-517051, an oil-containing composition containing an oil, a prescribed surfactant system, a prescribed solubilization auxiliary ingredient, and water under prescribed conditions is described, and a perfume can be cited as the oil.

[0005] Further, in Japanese Patent Application Laid-Open No. 2009-261929, a fragrance liquid containing a perfume and a surfactant, containing the surfactant at a ratio of 0.4 to 1 parts by weight per 1 part by weight of the perfume, and being transparent is described. SUMMARY

[0006] The present application provides a perfume composition and a perfume-imparting method in which the residual fragrance property in an object is excellent.

[0007] The present application relates to a perfume composition containing (A) a perfume compound (hereinafter referred to as the (A) component) and (B) a compound represented by the following Formula 1 (hereinafter referred to as the (B) component).

[0008] [Chemical Formula 1]

[0009]

[0010] (In the formula, R 1 and R 2 each are a hydrocarbon group, the total carbon number of R 1 and R 2 is 17 or greater, A 1 O and A 2 O each are an alkyleneoxy group in which A 1 and A 2 are alkylene groups having a carbon number of 2 or greater and 4 or less, x1 and x2 each are the average addition mole number of A 1 O and A 2 O, and each is a number of 0 or greater and 10 or less, and M is a cation.]

[0011] Further, the present application relates to a method for imparting a fragrance, wherein the above-mentioned fragrance composition of the present application is used to treat an object.

[0012] According to the present application, it is possible to provide a fragrance composition and a method for imparting a fragrance, which have excellent residual fragrance properties in an object. DETAILED DESCRIPTION

[0013] [Fragrance composition]

[0014] (A) Component is a fragrance compound.

[0015] As for the LogP of the (A) component, from the viewpoints of dispersion stability and residual fragrance properties, it is preferably 1 or more, more preferably 2 or more, further preferably 3 or more, and it is preferably 7 or less, more preferably 5 or less, further preferably 4 or less.

[0016] Here, the so-called LogP is the logarithmic value of the partition coefficient of a compound in 1-octanol / water, and means the ratio of the equilibrium concentration of a solute in each solvent in the partition equilibrium when the compound is dissolved as a solute in a 2-liquid-phase solvent system of 1-octanol and water. It is generally expressed in the form of the logarithm "logP" with respect to the base 10. That is, the logP value is an index of lipophilicity (hydrophobicity), and the larger the value, the more hydrophobic, and the smaller the value, the more hydrophilic.

[0017] As for the LogP, for example, a large number of LogP values of compounds are registered in a database available from Daylight Chemical Information Systems, Inc. (Daylight CIS) or the like, and can be referred to. Further, in the case where there is no measured LogP value, it can be calculated using a program "CLOGP" (Daylight CIS) or the like, and the reliability of the calculation using the program "CLOGP" is also high, and is suitable.

[0018] In the program "CLOGP", in the case where there is a measured value of LogP, a value of "calculated LogP (sometimes referred to as CLogP)" calculated using the fragment method of Hansch, Leo is output together with it. The fragment method is based on the chemical structure of a compound, and takes 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). This CLogP value is the most widely and reliably estimated value at present, and therefore in the case where there is no measured value of LogP in selecting a compound, it is appropriate to use the CLogP value instead. In the present application, as the LogP of the component (A), either the measured value of LogP or the CLogP calculated using the program "CLOGP" can be used.

[0044] (B) the component is a compound represented by the formula 1 described above. The reason why the residual fragrance property is improved by using the (B) component in combination with the (A) component is not clear, however, the present inventors and the like presume as follows. The perfume composition of the present application is usually compounded in the presence of water into a treatment liquid containing water, for example, and applied to an object such as a fiber. When the (A) component and the (B) component coexist in water, the (B) component forms a vesicle that solubilizes the (A) component. By the vesicle, the (A) component is adsorbed to the object and dehydration is promoted, thereby inhibiting the volatilization of the (A) component together with the moisture. In addition, the presence of the (A) component in the vesicle also contributes to the inhibition of the volatilization of the (A) component. That is, it is considered that the (B) component is excellent in the delivery effect of the (A) component in water to the object. It is considered that thereby the volatilization of the (A) component is inhibited and the residual fragrance property is improved. Note that the mechanism of the action of the present application is not limited to this.

[0048] In Formula 1, the hydrocarbon groups of R 1 and R 2 may be either linear or branched, but preferably contain a branched chain from the viewpoint of dispersibility in water. In the case where the hydrocarbon groups of R 1 and R 2 are branched, R 1 and R 2 preferably each have a side chain having a carbon number of 2 or more, and more preferably have a side chain having a carbon number of 3 or more, from the viewpoint of the remaining fragrance.

[0059] In the present application, the number of side chains means the number of side chains branched from the main chain, and even if a side chain further has a side chain branched therefrom, the number of side chains does not change. However, although a side chain can further have a side chain branched therefrom, from the viewpoint of the remaining odor, it is preferable that the side chain be a straight chain.

[0060] In the case where R 1 and R 2 each independently is a branched alkyl group having 10 or more and 12 or less carbon atoms, the number of branched carbons of R 1 and R 2 each can be the same or different, and from the viewpoint of the remaining odor, is 1 or more, and is preferably 3 or less, more preferably 2 or less.

In addition, in the case where the hydrocarbon group of R 1 and the hydrocarbon group of R 2When the hydrocarbon groups are the same, it is preferred from the viewpoint of residual aroma. For example, in Formula 1, R 1 The number of carbons and R 2 The number of carbon atoms can be the same or different.

[0118] (3-1) Evaluation 1 (residual fragrance based on paired evaluation)

[0119] The towel which had been treated in (2) was evaluated for residual fragrance after 8 hours and 24 hours from the start of dehydration by 4 panelists specializing in aroma. The towels of the example and the comparative example which had been dehydrated for the same elapsed time were compared in the same test group, and in the case where there was a difference in aroma intensity, 3 points were given to the stronger one and 1 point to the weaker one, and in the case where the aroma intensity was the same, 2 points were given to each, and the total score of the scores given by the 4 panelists was calculated. The results of the evaluation are shown in Table 1.

[0120] (3-2) Evaluation 2 (residual fragrance based on score evaluation)

[0121] The towel which had been treated in (2) was evaluated for residual fragrance after 4 hours and 24 hours from the start of dehydration by 4 panelists specializing in aroma in accordance with the following evaluation criteria. The scores given by the 4 panelists were added together for the towel which had been dehydrated for the same elapsed time in the same test group. At this time, the scores were given with reference to the evaluation criteria below to one decimal place.
