Description

Oral composition and gingiva massaging feeling imparting agent

Technical Field

The present invention relates to a gingival massaging feeling-imparting agent which has an excellent effect of imparting a massaging feeling to the gingiva and imparts a unique massaging feeling even after use in the oral cavity, and an oral composition containing the same.

Background

In oral compositions such as dentifrice, the feeling of effect is felt at the site of use, particularly at the gum, during and after use in the oral cavity, and the effect is expected to be improved in terms of prevention or suppression of periodontal diseases such as daily gingival inflammation, halitosis, and the like. From such a viewpoint, an oral composition which imparts a more satisfactory feeling of effect to the gum has been desired.

However, when stimulus components such as spilanthol and red pepper are mixed as flavors used in conventional oral compositions, the astringent, pungent, and bitter taste stimulus sensations are imparted, so that the gum can be given a firm feeling and a moderate stimulus feeling, and the effect feeling of various active ingredients mixed in the oral composition can be produced.

Patent document 1 (japanese patent No. 5251350) discloses: a dentifrice composition comprising a refreshing feeling-imparting agent such as sodium chloride or menthol, monomenthyl succinate and a specific surfactant in combination has a medicinal effect (tightening feeling of gum and moderate irritation), and further comprises an essential oil or extract such as spilanthol, black pepper and red pepper. As a technique for producing an effect feeling by applying a flavor such as Japanese pepper, patent document 2 (Japanese patent No. 5748626) proposes an oral composition in which a combined system of Japanese pepper extract and guaiacol or ethylguaiacol at a specific ratio is used as a bactericide, which has a good medicinal effect feeling and effect feeling, and a supercritical extract of Japanese pepper (Zanthoxylum piperitum) belonging to the genus Zanthoxylum is used as the Japanese pepper extract. Patent document 3 (patent No. 5897843) discloses: patent document 4 (japanese patent laid-open publication No. 2015-43769) discloses that a specific flavor extract such as capsicum, zanthoxylum piperitum, and black pepper is mixed in an oral composition to enhance and maintain the taste and pleasant feeling of mints: the oral composition containing hydroxy-alpha-sanshool and/or 2-phenylbutenal has strong salivation effect and moistening effect. Patent document 5 (japanese patent laid-open No. 2012 and 246278) discloses that an extract of a plant of the genus zanthoxylum of the family rutaceae or the like as a pungent ingredient having astringency can be applied as a refreshing agent to an oral composition, and patent document 6 (patent No. 5171104) discloses that when α -phellandrene and menthol are mixed in a specific ratio in an oral composition, the refreshing feeling of menthol is enhanced.

Disclosure of Invention

Technical problem to be solved by the invention

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gingival massaging sensation imparting agent which has an excellent effect of imparting a massaging sensation to the gingiva without using a stimulating component such as spilanthol and which imparts a unique massaging sensation in the oral cavity from the time of use to the time after use, and an oral composition containing the same.

Means for solving the problems

The present inventors have made intensive studies to achieve the above object, and as a result, have recognized that: when the above-mentioned components (a) selected from 1 or more of sanshool and its derivatives, particularly component (a) derived from Sichuan pepper, and (b) alpha-phellandrene, particularly component (b) derived from Pink pepper, are used in combination, the gum is given a unique massaging feeling. Further, the present inventors have found that a system combining components (a) and (B), particularly a system combining component (a) a sichuan pepper extract and a pink pepper extract, is mixed into an oral composition as an effective component for imparting a massaging sensation to gums, whereby the oral composition is excellent in the effect of imparting a massaging sensation to gums, can impart a pleasant and moderately high unique massaging sensation to gums even after use in the oral cavity, and can ensure a good feeling of use with suppressed unpleasant taste, and have completed the present invention.

That is, in the present invention, when the components (a) and (B), particularly the components (a) and (B), are used in combination, the two components act synergistically with each other to provide a massage feeling, and a unique massage feeling can be satisfactorily provided to the gum from the time of use to the time of use in the oral cavity (the gum is massaged by a moderate stimulation such as breaking of fine bubbles to the gum, and the gum feels a tight state).

More specifically, when the component (a) (component (a)) is mixed alone and the component (B) (component (B)) is mixed alone, the effect of imparting a massaging sensation to the gums is low, and the massaging sensation of the gums during use or after use is poor. However, surprisingly, in the present invention, by using the components (a) and (B) together (components (a) and (B)), it is possible to provide a superior massaging feeling to the gum while maintaining a good taste without feeling unpleasant irritation or the like caused by these components as an unpleasant taste (see examples described later).

The action and effect of the present invention are specific and specific action and effect to the specific combination system, and the effect of imparting a massage feeling is poor when the component (a) (component (a)) is absent or the component (B) (component (B)) is absent (see comparative examples 1 and 2 described later).

Patent document 1 discloses an improvement in the medicinal effect due to sodium chloride or the like, and an improvement in the taste due to addition of red pepper, black pepper extract (main component is piperine) or the like, and patent document 2 discloses an improvement in the medicinal effect due to the use of a mountain pepper extract or the like in combination with a bactericide. Further, patent document 6 is to enhance the cooling sensation of menthol by α -phellandrene. On the other hand, in the present invention, the components (a) and (B) (the components (a) and (B)) are used in combination to give a unique massaging feeling to the gum, and the specific and special actions and effects of the combination system in the present invention cannot be expected from patent documents 1 to 6 which do not mention the combination use of these components.
