Description

The present invention relates to a composition for supplementing a young female odor.

In recent years, people of both men and women have become more interested in odor etiquette. Research on various body odors has been enthusiastically carried out, and the main causative odors such as sweat odor, axillary odor, foot odor, and aging odor have been identified. For example, body odor is generally thought to be due in part to fatty acids and unsaturated aldehydes produced from sebum on the surface of the body. Similarly, in the case of odor called aging odor, ω-unsaturated fatty acids (palmitoleic acid and vaccenic acid) produced by decomposition of sebum are further oxidatively decomposed to generate unsaturated aldehyde called 2-nonenal on the body surface. It has been reported that it is deeply related to the above (Non-Patent Document 1).

As a technique for preventing such body odor such as aging odor, a method of masking with perfume or the like and a method of utilizing the odor adsorption effect of charcoal (Patent Document 1) are known. Further, a method using an extract from the root and rhizome of Sanguisorba officinalis (Patent Document 2), a method using condensed persimmon tannin (Patent Document 3), and the like have been proposed. Furthermore, the development of a cleaning agent for washing away unpleasant odor components is also underway.

On the other hand, although it is said that such body odors such as aging odors exist in both men and women, the fact is that research on changes in body odors associated with aging of women has not progressed sufficiently. Therefore, it is desired to develop a product for measures against the odor of aging suitable for women.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a product suitable for females for rejuvenating body odor and a product for measures against aging odor. Furthermore, it is also an object of the present invention to focus on changes in body odor with aging of females and to provide a method for evaluating a substance having an anti-aging effect.

As a result of analyzing the body odor component of females in their teens to 50s, the present inventors have sensually apparently sweet scent (SWEET odor) in females (young women) in their teens to 20s. Found that can be confirmed. After the sensory evaluation, the components were analyzed to identify specific body odor components. It was also clarified that nonenal odor, which is generally known as a causative substance of aging odor, is weaker in females than in males, and there is no difference between ages. Then, they have found that by supplementing the odor component constituting the body odor of the above-mentioned young woman, which decreases with aging, the body odor can be rejuvenated and the odor of the woman can be suppressed, and the present invention is completed. It came to.

[Composition for supplementing young female odor]
The composition of the present invention is a composition for supplementing a young female odor used for supplementing an odor component constituting the body odor of a young female, and contains at least a lactone compound represented by the following formula (I). Since the composition of the present invention can rejuvenate the body odor of women, it can be suitably used as an external composition for measures against the odor of aging of women. On the other hand, by using the composition of the present invention for an object to which a body odor component is likely to adhere due to the use of bedding, for example, the effect of rejuvenating the odor emitted from the attached body odor component can be expected. It can also be suitably used for products, hard surfaces, or spaces. The body odor in the present invention refers to all odors emitted by women, and includes odors from the back, nape, and behind the ears, scalp odor, sweat odor, axillary odor, and foot odor.

Although body odor is composed of various components, our studies have revealed that in females, the amount of certain lactone compounds in body odor decreases with age. That is, although a specific lactone compound is sufficiently contained in the body odor of young women in their teens to early twenties, it decreases with age. On the other hand, the amount of nonenal, which is a conventionally known causative substance of aging odor, in the body odor was originally small in the case of females, and there was no tendency for it to increase with aging. Therefore, the present inventors have included more in the body odor of young women as a measure against the aging odor of women than the suppression of nonenal odor and masking with perfume, which are usually performed as a measure against the odor of men. However, I thought that it would be more effective to supplement a specific component that decreases with aging, and as a result of conducting research, it was found that the present invention was completed and the effects of the above-mentioned invention could be obtained. It is said that.

In the formula, R is an alkyl group having 2 to 9 carbon atoms. The carbon number of R is preferably 3 to 9, more preferably 4 to 9, further preferably 5 to 8, and particularly preferably 6 or 7. The hydrogen atom contained in the above alkyl group may be substituted.

Specific examples of the lactone compound represented by the above formula (I) include γ-hexalactone, γ-heptalactone, γ-octalactone, γ-nonalactone, γ-decalactone, γ-undecalactone, and γ-dodeca. Examples thereof include lactone and γ-toridecalactone. Of these, γ-nononalactone, γ-decalactone, γ-undecalactone and γ-dodecalactone are preferable, and γ-decalactone and γ-undecalactone are more preferable. These lactone compounds are components having a fruity scent such as peach, apricot, and coconut. The lactone compound may be used alone or in combination of two or more.

The content of the lactone compound represented by the formula (I) in the composition of the present invention is 0.00001% by weight to 10% by weight, and 0.00005% by weight from the viewpoint of the effect on measures against the aging odor of women. % To 5% by weight, more preferably 0.0001% by weight to 3% by weight, further preferably 0.0005% by weight to 2% by weight, and 0.001% by weight to 1% by weight. It is particularly preferable to be% by weight. When two or more lactone compounds are used in combination, the total amount thereof is within the above numerical range.

There are many types of odor components constituting the body odor of young women other than the lactone compound represented by the above formula (I). The composition of the present invention may contain other odorous components constituting the body odor of young women other than the lactone compound represented by the above formula (I). Examples of the odor component constituting the body odor of other young women include aldehydes, fatty acids, ketones, sulfur compounds (S-based odor), nitrogen compounds (N-based odor) and the like. As the odor component constituting the body odor of other young women contained in the composition of the present invention, a component whose content in the body odor decreases with age of the woman is preferable.

In addition to the above-mentioned components, the composition of the present invention may contain the following optional components as long as the effects of the present invention are not impaired.

[Test 1]
T-shirts with cloth sewn on the back are dressed by Japanese women (n = 50) in their late teens to 50s from after bathing to before bathing the next day, and after collecting the cloth, there are 5 categories (nonenal odor). , Fatty acid odor, amine / ammonia odor, S-based odor, SWEET odor) were evaluated by a professional panelist (professional) on a 6-point scale. The criteria for the above 6-step score (odor intensity; 0 to 5) are shown in Table 1, and the results are shown in FIGS. 1 to 4. 1 and 2 show the SWEET odor sensory evaluation score, and FIG. 3 shows the nonenal odor sensory evaluation score. Furthermore, the recovered cloth was subjected to odor analysis using a headspace gas chromatography mass spectrometer (HSS-GC / MS). The results of the study on the correlation between the concentration of nonenal (ppm) and the age of the subject (sample) are shown in FIG. We also examined the correlation between the concentration (ppm) of each lactone component (γ-decalactone, γ-undecalactone) and the age of the subject (sample), and the results are shown in FIG.

As shown in FIGS. 1 and 2, it was found that the SWEET odor was high from the female in the late teens to the early 20s, and the odor decreased with aging. Note that FIG. 1 is a bar graph of each data in FIG. 2 by age group. Further, as shown in FIGS. 3 and 4, no clear correlation was observed between the age and the sensory score of nonenal odor, and it was found that the odor intensity itself was lower than that of males. In addition, HSS-GC / MS revealed that the main components of the SWEET odor were γ-decalactone and γ-undecalactone.

As a result of investigating the correlation between the total amount of γ-decalactone and γ-undecalactone and age, as shown in FIG. 5, as shown in FIG. It was also confirmed that the concentration decreased after the thirties. It was found that around the age of 35 was a major change point (smell corner) of the SWEET odor.

[Test 2]
A cotton ball (White Cross No. 10) impregnated with 10 μL of model aging odor containing Trans-2-nonenal and 1 μL of a single raw material of various γ-lactones was placed in a container and sealed. After 30 minutes, the degree of comfort and discomfort with respect to the model's aging odor was evaluated. The evaluation was carried out by a panel of four people centered on the evaluator. Various γ-lactones were diluted with dipropylene glycol to 1% or 10% before use. The criteria for the evaluation score are shown in Table 2 below, and the results are shown in Table 3 and FIG.

The discomfort with the model aging odor was not improved by γ-valerolactone (Comparative Example 1), but γ-hexalactone (Example 1), γ-heptalactone (Example 2), and γ-octalactone (Example 2). When γ-decalactone (Example 4) and γ-undecalactone (Example 5) were added, the quality of the odor was improved and the odor became pleasant.

[Test 3]
While sniffing various scents, I evaluated the impression of the female in the photo (4 photos in total). Specifically, "2-nonenal", "soap fragrance", and "lactone C10 / lactone C11-containing fragrance", which are "unscented" and have odor intensity 2 of the 6-step odor intensity display method, are prepared. We conducted a questionnaire survey on "femininity,""youthfulness," and "attractiveness" by looking at photographs of women (actual age average 40 years old) while sniffing one of the scents (n = 52). The evaluation was performed by general males and general females (30 years old and over). Figure 7 shows the impressions (%) of "femininity,""youthfulness," and "attractiveness" when the fragrance-free content is 100%.

When there was a scent containing γ-decalactone (R = 6) and / or γ-undecalactone (R = 7), the female in the photograph was evaluated to have a lower apparent age and an increased youthfulness. In addition, it was evaluated to improve femininity, attractiveness, and likability. It is known that many general women feel their own body odor changes with age, and one of the causes is "SWEET odor", which is a body odor component peculiar to young women. It was speculated that the decrease in "lactone C10 / lactone C11" after the thirties caused a change in body odor. Furthermore, from the above test results, it was also found that the function of "lactone C10 / lactone C11" has the effect of increasing femininity, youthfulness, and attractiveness. According to this study, as an approach to women's odor of aging, it is more effective for women's odor of aging by adding the scent of "Lactone C10 / Lactone C11" instead of simply removing it by washing. It was thought that a new approach was possible.

[Test 4]
The detergent (body soap) having the composition shown in Table 4 below was prepared by a conventional method.

Changes in the impression of females were evaluated before and after the use of the cleaning agent (body soap) having the composition shown in Table 4 above. Specifically, we conducted a questionnaire survey on "femininity," "attractiveness," "youthfulness," and "freshness" by looking at women (n = 2). Table 5 shows the impressions (%) of "femininity", "attractiveness", "youthfulness", and "freshness" after using the sample, with 100% being used before the sample was used.

[Test 5]
The antiperspirant having the composition shown in Table 6 below was prepared by a conventional method.

Changes in the impression of females were evaluated before and after the use of the antiperspirant having the composition shown in Table 6 above. Specifically, we conducted a questionnaire survey on "femininity," "attractiveness," "youthfulness," and "freshness" by looking at women (n = 2). Table 7 shows the impressions (%) of "femininity", "attractiveness", "youthfulness", and "freshness" after using the sample, with 100% being used before the sample was used.
