Description

The present invention relates to a fragrance for wallpaper aroma, which is excellent in fragrance standing and fragrance persistence after being attached to wallpaper.

Traditionally, scent-based approaches have been taken to make life more comfortable. In particular, in recent years, the use of scents in daily life has become more and more active, and various products that add scents to various things in the living environment have been created. As a scenting method, air fragrance is added by scattering the fragrance component and floating in the air (see, for example, Patent Document 1 and Patent Document 2), and fragrance component is attached to the textile product to add the fragrance component. Examples include incense (see, for example, Patent Document 3).

On the other hand, there are also approaches to prevent, reduce or eliminate unpleasant odors in order to make life more comfortable. Such methods include a method using an active ingredient that olfactoryly neutralizes (masks) an unpleasant odor component (see, for example, Patent Document 4), and physical, chemical, and biological neutralization (see, for example, Patent Document 4). Examples thereof include a method of utilizing an active ingredient that deodorizes (see, for example, Patent Document 5).

Japanese Unexamined Patent Publication No. 2009-136374 Japanese Unexamined Patent Publication No. 2011-212271 Japanese Unexamined Patent Publication No. 2003-201669 International Publication No. 2002/066083 International Publication No. 2012/090580

Various products for fragrance have been created, but as a scenting method, aroma of air as disclosed in Patent Document 1 and Patent Document 2 and a fiber aroma as disclosed in Patent Document 3 are added. Limited to incense, in that respect fragrance products are saturated. On the other hand, there is an increasing awareness of pursuing the further affluence of the living environment, and in order to satisfy consumers, new fragrance products for making the living environment comfortable are required.

In order to search for a product that can scent the space by a method different from the conventional one, the present inventor adheres a fragrance component to the surface of the fiber and the surface of the wallpaper with the same initial fragrance intensity, and examines the sustainability of the scent. did. Surprisingly, they found that the surface area of the wallpaper was significantly smaller in surface area for retaining the fragrance component, but the scent persistence was significantly higher than that of the fiber surface. Based on this discovery, we came up with the idea of a novel use of adding fragrance to the space by incense the wallpaper.

In order to effectively perfume the wallpaper for indoor scenting, it is necessary for the fragrance component attached to the wallpaper to scent well and to maintain the scent. However, according to the study of the present inventor, a fragrance component having a good scent when attached to the wallpaper has a poor scent persistence, and a fragrance component having a good scent persistence has a poor scent retention when attached to the wallpaper. It was a thing. In other words, the use of scenting wallpaper has a unique problem that it is difficult to achieve both scent standing and scent persistence.

A technique for applying a fragrance component to a surface is reported in Patent Document 4. US Pat. Disclose how to prevent and neutralize. It is also described that this method can be applied to the surface of fibers (for example, cloth) and the surface of wallpaper. However, the technique of Patent Document 4 is aimed at preventing or neutralizing the malodor of smoke "on the surface", and the particular musk selected as a solution thereof is particularly on the surface of the fiber (eg, cloth). It is described as effective and has a characteristic that the vapor pressure is extremely low. Therefore, even if the above-mentioned specific musk is classified as a fragrance by itself, the purpose is to positively scent the fragrance component from the wallpaper to fragrance the space when applied to the wallpaper. It is not a thing, nor is it an ingredient that can be scented from wallpaper to the extent that it can actually scent the space effectively.

Therefore, an object of the present invention is to provide a fragrance for wallpaper aroma, which is excellent in fragrance standing and fragrance persistence after adhering to wallpaper.

As a result of diligent studies, the present inventor has an excellent fragrance component having a specific vapor pressure and a cyclic structure, which is excellent in scent standing and scent persistence after adhering to wallpaper, and is effective for wallpaper aroma. I found that. The present invention has been completed by further studies based on this finding.

That is, the present invention provides the inventions of the following aspects.

(Evaluation of fragrance)
×: Initial strength less than 3.0 points ◎: Initial strength 3.0 points or more and less than 4.5 〇: Initial strength 4.5 or more Initial strength 3.0 or more was used as the acceptance criterion for fragrance. When the initial intensity is 3.0 or more, the scent can be easily perceived in an actual usage environment where the distance between the wallpaper and the consumer is farther than that of 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 usage environment, so that the space can be scented more comfortably.

(Evaluation of fragrance persistence)
×: Damping strength less than -0.2 〇: Damping strength -0.2 or more

As shown in Comparative Examples 1 to 8, the fragrance component having a vapor pressure of 0.010 to 1.0 hPa and a linear type (that is, having no cyclic structure) has an initial strength of 3.0 or more. Although the scent was good enough to effectively scent the space in the actual usage environment, the damping intensity was less than -0.2, and the scent persistence was poor. Further, among these, except for Comparative Example 3 and Comparative Example 4, the initial intensity was 4.5 or more, and the proportion of those having too strong fragrance in the actual usage environment tended to be high.

On the other hand, as shown in Examples 1 to 12, the fragrance component having a vapor pressure of 0.010 to 1.0 hPa and having a cyclic structure has an initial strength of 3.0 or more, and is a space in an actual usage environment. The scent was so good that it could be effectively scented, the damping intensity was -0.2 or more, and the scent persistence was also good. Among these, as shown in Examples 1 to 8, all the fragrance components having a vapor pressure of 0.10 hPa or less have an initial strength of less than 4.5, and have an appropriate scent that gives a more comfortable scent to the space. There was a tendency for it to be easily obtained.

Even if the fragrance component has a cyclic structure, as shown in Comparative Example 9 and Comparative Example 10, the fragrance component having a vapor pressure of less than 0.010 hPa has an initial strength of less than 3.0 and adheres to the wallpaper. The scent did not stand out from the scented state, and it was not possible to effectively scent the space in the actual usage environment. Further, as shown in Comparative Example 11 and Comparative Example 12, the fragrance component having a vapor pressure of more than 1.0 hPa had a decay intensity of less than −0.2, and the fragrance had poor sustainability.

Test Example 2:
The attenuation strength was the same as that of Test Example 1 except that the fragrance component of Example 6 was used and the target to which the fragrance component was attached was a cotton cloth (Comparative Example 13) or a polyester cloth (Comparative Example 14) instead of the wallpaper. evaluated. Further, the fragrance component of Example 8 was used, and the attenuation was the same as that of Test Example 1 except that the target to which the fragrance component was attached was a cotton cloth (Comparative Example 15) or a polyester cloth (Comparative Example 16) instead of the wallpaper. The strength was evaluated. As the cotton cloth, JIS L 0803 compliant dyeing fastness test attached white cloth cotton (Kanakin No. 3) manufactured by the Japanese Standards Association is used, and as the polyester cloth, JIS L 0803 compliant dyeing manufactured by the Japanese Standards Association. The attached white cloth polyester for fastness test was used. Graphs comparing the damping strengths when the fragrance component is attached to the wallpaper, cotton cloth and polyester cloth are shown in FIGS. 1 (a) and 1 (b). In the figure, poly cloth refers to polyester cloth. As shown in these figures, the fragrance component used in the present invention is compared with the case where the attachment target is a cotton cloth (Comparative Example 13 and Comparative Example 15) and the case where the polyester cloth is used (Comparative Example 14 and Comparative Example 16). When the object to be adhered was used as wallpaper (Examples 6 and 8), the attenuation of the scent was remarkably suppressed, and it was shown that the durability of the scent was extremely excellent.
