Description

TECHNICAL FIELD The present invention relates to a perfume for perfuming wallpaper, which is excellent in fragrance release and fragrance persistence after adhering to wallpaper.

From the past, approaches from the perspective of fragrance have been made to make life more comfortable. Especially in recent years, the use of scents in daily life has become more and more positive, and various products have been created for adding scents to various things in the living environment. As a method of scenting, air scenting by scattering perfume ingredients and floating in the air (for example, see Patent Document 1 and Patent Document 2), textile products by attaching perfume ingredients to textile products. incense (see, for example, Patent Document 3).

On the other hand, approaches to prevent, reduce, or eliminate unpleasant odors are also being taken to make life more comfortable. Examples of such techniques include a method using an active ingredient that olfactorily neutralizes (masks) unpleasant odor components (see, for example, Patent Document 4), and physical, chemical, and biological neutralization ( A method using an active ingredient for deodorization (see, for example, Patent Document 5).

JP 2009-136374 A JP 2011-212271 A Japanese Patent Application Laid-Open No. 2003-201669 WO2002/066083 WO2012/090580

Various fragrance products have been created. It is limited to incense, and in that respect, fragrance products are saturated. On the other hand, there is an increasing awareness of the pursuit of a richer living environment, and in order to satisfy consumers, there is a demand for new aromatic products that make the living environment more comfortable.

In order to search for a product that can scent a space by a method different from the past, the present inventor attached perfume ingredients with the same initial fragrance strength to the surface of the fiber and the surface of the wallpaper, and examined the persistence of the scent. bottom. Surprisingly, the inventors discovered that the surface of the wallpaper has a much smaller surface area capable of holding the fragrance components, but the fragrance persists remarkably higher than that of the fiber surface. Based on this discovery, we came up with the idea of a novel use of scenting a space by perfuming the wallpaper.

In order to effectively perfume the wallpaper for room fragrance, it is necessary that the perfume component adhered to the wallpaper emits a good fragrance and maintains the fragrance. However, according to the studies of the present inventors, a perfume component that retains a good scent when adhered to wallpaper has poor scent persistence, and a perfume component that retains a good scent has a poor scent when adhered to wallpaper. It was something. In other words, we faced the unique problem of difficulty in achieving both the release of fragrance and the persistence of fragrance in the use of perfumed wallpaper.

A technique for applying a perfume component to the surface is reported in Patent Document 4. US Pat. No. 5,331,001 discloses that a composition containing one or more macrocyclic musks selected from cyclohexadecanolide, cyclopentadecanone, or cyclopentadecanolide is used on a surface to reduce the odor of smoke on the surface. Disclosed are methods for preventing and neutralizing The method is also described as being applicable to textile surfaces (eg cloth) and wallpaper surfaces. However, the technique of Patent Document 4 is aimed at preventing or neutralizing smoke malodors "at the surface", and the specific musk selected as the solution is particularly It is described as effective and has very low vapor pressure properties. Therefore, even if the above-mentioned specific musk is classified as a fragrance per se, it is intended to make the space fragrant by positively letting the fragrance components out of the wallpaper when applied to the wallpaper. It's not a product, nor is it an ingredient that can actually make the wallpaper smell good enough to effectively scent the space.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a perfume for perfuming wallpaper, which is excellent in fragrance release and fragrance persistence after adhering to wallpaper.

As a result of intensive studies, the inventors of the present invention found that a perfume component having a specific vapor pressure and a cyclic structure is excellent in fragrance release and fragrance persistence after adhering to wallpaper, and is effective for wallpaper perfuming.

Test example 1
0.05 g of perfume is put in a screw tube (No. 6, 30 mL), and the opening (15 mm in diameter) is covered with a 3 cm square piece of wallpaper (manufactured by Kikuchi Fusuma Paper Mill Co., Ltd.; trade name: raw glue wallpaper; the outermost layer is polyethylene covered with a vinyl chloride layer). The outermost surface layer of the wallpaper piece was covered so as to be in contact with the air inside the screw tube. The scented screw tube with the opening covered with wallpaper pieces is heated with a heater set at a heating temperature of 70 ° C. for 5 minutes to evaporate the scent component. was allowed to stand for 30 minutes in a room. As a result, the fragrant component was adhered to the wallpaper piece.

The strip of wallpaper was removed from the screw tube and placed in an odor test bag. 3 L of odorless air (23°C) was filled in the bag for the scent test containing the wallpaper pieces, and the bag was sealed. After standing at room temperature for 30 minutes, the degree of the strength of the scent of the internal air (initial strength) was measured. Perfume standing was evaluated by sensory evaluation.

The wallpaper piece subjected to the sensory evaluation of initial strength was taken out of the bag for the scent test, allowed to stand in a room at room temperature for 7 hours, and then placed in another bag for the scent test. A bag for fragrance test containing wallpaper pieces was filled with 3 L of odorless air and sealed, and sensory evaluation was performed on the degree of fragrance intensity of the internal air (strength after standing) at the point of 30 minutes after standing at room temperature. The persistence of fragrance was evaluated by obtaining the attenuation strength by subtracting the initial strength from the strength after standing.

The degree of fragrance intensity was determined by averaging the scores scored by 8 subjects on 11 levels in 0.5-point increments based on the following criteria.
0 points: no odor 1 point: barely perceptible odor 2 points: weak odor that can be identified 3 points: easily perceivable odor 4 points: strong odor 5 points: strong odor

(Evaluation of scent release)
×: Less than 3.0 points for initial strength ◎: 3.0 points or more to less than 4.5 points for initial strength ◯: 4.5 points or more for initial strength Initial strength of 3.0 or more was used as an acceptance criterion for the scent release. When the initial intensity is 3.0 or more, the scent can be easily felt in the actual use environment where the distance between the wallpaper and the consumer is longer than that in the test method, so that the space can be effectively scented. Among them, when the initial intensity is less than 4.5, the scent is not too strong in the actual use environment, so the space can be scented more comfortably.

(fragrance persistence evaluation)
×: Attenuation intensity - less than 0.2 〇: Attenuation intensity -0.2 or more

As shown in Comparative Examples 1 to 8, the linear type (that is, not having a cyclic structure) perfume component having a vapor pressure of 0.010 to 1.0 hPa has an initial strength of 3.0 or more, Although the scent was good enough to effectively scent the space in the actual use environment, the attenuation strength was less than -0.2, and the scent persistence was poor. In addition, among these, except for Comparative Examples 3 and 4, the initial strength was 4.5 or more, and there was a tendency that the percentage of those with too strong fragrance in the actual use environment was high.

On the other hand, as shown in Examples 1 to 12, the perfume component having a vapor pressure of 0.010 to 1.0 hPa and a cyclic structure has an initial strength of 3.0 or more, and a space In addition, the attenuation strength was -0.2 or more, and the fragrance persistence was also good. Among these, as shown in Examples 1 to 8, all of the perfume ingredients having a vapor pressure of 0.10 hPa or less have an initial strength of less than 4.5, and have a moderate scent that makes the space more pleasant to smell. A tendency to be easily obtained was observed.

In addition, even for perfume ingredients having a cyclic structure, as shown in Comparative Examples 9 and 10, the perfume ingredients having a vapor pressure of less than 0.010 hPa had an initial strength of less than 3.0 and adhered to the wallpaper. The aroma was not released when the perfume was applied, and the space could not be effectively scented in the actual use environment. Further, as shown in Comparative Examples 11 and 12, the attenuation strength of the perfume component having a vapor pressure of more than 1.0 hPa was less than -0.2, indicating that the persistence of the scent was poor.

Test example 2:
The attenuation strength was measured in the same manner as in Test Example 1, except that the perfume component of Example 6 was used and the object to which the perfume component was adhered was cotton cloth (Comparative Example 13) or polyester cloth (Comparative Example 14) instead of wallpaper. evaluated. In addition, attenuation was performed in the same manner as in Test Example 1 except that the perfume component of Example 8 was used and the target to which the perfume component was adhered was cotton cloth (Comparative Example 15) or polyester cloth (Comparative Example 16) instead of wallpaper. strength was evaluated. As the cotton cloth, the attached white cloth (Kanakin No. 3) for color fastness test compliant with JIS L 0803 manufactured by the Japanese Standards Association was used, and as the polyester cloth, JIS L 0803 manufactured by the Japanese Standards Association was dyed Attached white cloth polyester for fastness test was used. FIG. 1(a) and FIG. 1(b) show graphs comparing the attenuation strength when the perfume component is adhered to wallpaper, cotton cloth and polyester cloth. In the figure, poly fabric refers to polyester fabric. As shown in these figures, the perfume ingredients used in the present invention are different when the adhesion target is cotton cloth (Comparative Examples 13 and 15) and when the polyester cloth is used (Comparative Examples 14 and 16). It was shown that the attenuation of the fragrance was remarkably suppressed when the wallpaper was attached (Examples 6 and 8), and the persistence of the fragrance was extremely excellent.
