Abstract

PROBLEM TO BE SOLVED: To provide a perfume composition for an oral cavity exhibiting a fruit like flavor of a natural feeling when being incorporated into a composition for an oral cavity, and a composition for an oral cavity including the perfume composition for an oral cavity.SOLUTION: A perfume composition for an oral cavity includes furaneol and/or rasberry ketone. A composition for an oral cavity includes the perfume composition for an oral cavity. In the composition for an oral cavity, preferably, the content of the furaneol is 0.001 to 0.05 mass% to the whole content of the composition for an oral cavity and/or the content of the raspberry ketone is 0.0005 to 0.005 to the whole content of the composition for an oral cavity.

Description

  The present invention relates to a fragrance composition for oral cavity that has high palatability for use in an oral composition and prevents color change with time of the formulated oral composition. More particularly, the present invention relates to an oral flavor composition containing furaneol and / or raspberry ketone and not containing maltol and ethyl maltol. Furthermore, it is related with the composition for oral cavity which does not produce a coloring change with time by using the said composition for oral cavity and saccharin sodium together.

  There are many children who dislike the use of the composition for oral cavity, and the use frequency and the use time cannot be sufficiently secured. As a result, there is a problem that a satisfactory oral hygiene state cannot be maintained. One of the reasons why children hate using oral compositions is that the flavor of oral compositions may not match the tastes of children, so there have been attempts to devise flavoring agents to be added to oral compositions. It is made from. In general, since children have a high preference for sweet flavors such as fruits, many attempts have been made to impart fruit-like flavors to children's products. Specifically, specific natural flavors, esters, alcohols, aldehydes, ketones, phenols, ethers from the aspect of palatability such as masking of raw materials, improvement of flavor of raw materials, refreshing feeling, refreshing feeling, etc. It has been proposed to blend at least one or two or more natural or synthetic fragrances selected from the group consisting of lactones, hydrocarbons, nitrogen-containing and / or sulfur-containing compounds, and acids. (Patent Document 1) In particular, in oral compositions, it is known that a natural fruit feeling can be obtained when maltol or ethyl maltol is blended with a fruit-based fragrance. However, when maltol or ethyl maltol is added to the oral composition, there is a problem that the oral composition causes a color change over time. In order to deal with this problem, a method of masking a change in color over time by coloring an oral composition with an appearance color reminiscent of a fruit expressed by a blended flavor is employed. In recent years, the increasing number of consumers who dislike the incorporation of colorants has led to the development of a method to fundamentally resolve the color change over time of oral compositions with fruit-like flavors. There are no proposals that can be made.

JP-A-2005-15686

  This invention makes it a subject to provide the composition for oral cavity which does not produce the time-dependent coloring change of the composition for oral cavity which has a fruit-like flavor and was mix | blended.

  As a result of intensive studies in view of such circumstances, the present inventors have surprisingly changed the temporal color change of the oral composition by containing furaneol and / or raspberry ketone and not containing maltol and ethyl maltol. An oral fragrance composition that does not occur is found, and by adding saccharin sodium to the oral fragrance composition, an oral composition that has high palatability and does not change over time has been found, and the present invention has been completed.

That is, this invention provides the composition for oral cavity containing the fragrance | flavor composition for oral cavity of 1-5 clause, and the said composition for fragrance | flavors.
Item 1. An oral flavor composition comprising furaneol and / or raspberry ketone.
Item 2. An oral composition comprising the oral flavor composition according to Item 1.
Item 3. The content of furaneol is 0.001 to 0.05 mass% with respect to the total amount of the oral composition, and the content of raspberry ketone is 0.0005 to 0.005 with respect to the total amount of the oral composition. Item 3. The oral composition according to Item 2.
Item 4. Furthermore, the composition for oral cavity of any one of claim | item 2 or claim | item 3 characterized by containing saccharin sodium.
Item 5. It is a dentifrice composition, The composition for oral cavity of any one of Claims 2-4 characterized by the above-mentioned.

  The oral fragrance composition of the present invention is effective in that it can impart a fruity flavor with high palatability to the oral composition while preventing changes in coloration of the combined oral composition over time.

  The fragrance composition in the present invention contains furaneol and / or raspberry ketone. The content in the composition for oral cavity is usually 0.001 to 0.05 mass% with respect to the total amount of the composition in the case of furaneol, and 0.0005 to 0.005 mass with respect to the total amount of the raspberry ketone. In particular, when included in the dentifrice composition, furaneol is 0.004 to 0.05 mass% with respect to the total amount of the dentifrice composition, and raspberry ketone is 0.0005 to 0.00 with respect to the total amount of the toothpaste composition. 005% by mass is preferred. In addition, it is necessary that the oral flavor composition in the present invention is substantially free of maltol and ethyl maltol. “Substantially not contained” means “not blended for flavoring”. For example, maltol is known as a naturally occurring component, but generally the amount of maltol mixed in a natural product is very small. Therefore, as a result of blending a natural product ingredient containing maltol, the content of maltol contained to a degree is very small, and even if the maltol is excluded, it does not affect the flavor. I can say no. More specifically, when the total content of maltol is 0.0001% by mass or less with respect to the entire composition, it is determined as “substantially not contained”.

  When the oral fragrance composition of the present invention is contained in the oral composition, it may be contained alone, but it is preferable to contain it together with sodium saccharin because it is easy to realize a natural fruit feeling. Moreover, although it does not limit as a composition for oral cavity, since the effect appears notably in the case of the dentifrice composition in which the fragrance | flavor rate of a fragrance | flavor composition is generally set high, it is preferable.

Investigation of palatability and evaluation of color change over time in dentifrice composition
According to the following, the palatability and color change with time when an oral flavor composition containing furaneol and raspberry ketone was contained in a dentifrice composition were evaluated according to the following procedure.
A dentifrice composition having the composition described in Table 1 was prepared according to a conventional method.
The preference survey was conducted using four specialist panelists and evaluated the balance and strength of the flavor as a fruit flavor, and the degree of natural impression. Specifically, about 1 g of the dentifrice composition as a subject was taken on a commercially available toothbrush, the mouth was rinsed after brushing the teeth for about 2 minutes, and the state immediately after that was evaluated. The following four grades were used as evaluation criteria.

4 Very good 3 Good 2 Somewhat bad 1 Bad

Evaluation of the color change with time was performed by filling about 25 g of the dentifrice composition prepared above in a laminate tube having a diameter of about 22 mm and a length of about 12 cm, leaving it at 40 ° C. for 12 hours, and then squeezing about 5 cm on a white plate. The appearance was visually evaluated. In the evaluation, the sample of Comparative Example 4 that was allowed to stand at −5 ° C. for 12 hours was used as a standard. Evaluation was carried out according to the following criteria.

3 No coloring allowed 2 Some coloring allowed 1 Remarkable coloring allowed

Comprehensive evaluation was carried out according to the following criteria.
◎ Taste rating is 4 or 3, and color change with time is 3
○ Preference is 2 and color change over time is 3
× Other than above

The above evaluation results are shown in Table 2.

  The dentifrice composition containing either the decoy, furaneol or raspberry ketone shown in Table 2 gave good results. On the other hand, in the case of Comparative Examples 1 and 2 in which maltitol or ethyl maltol is contained in an amount that allows sufficient sweetness to be felt, remarkable coloring is seen in the dentifrice composition. It was found that coloring of the dentifrice composition also occurred. Further, when none of furaneol, raspberry ketone, maltol and ethyl maltol was contained, sweetness was felt, but the flavor was far from natural fruits, which was not preferable.
