Description

[Technical field]

[0001] The present invention relates to an oral composition. [Background technology]

[0002] Dentifrice compositions usually contain flavorings containing menthol or mint oil, which are used to improve the feeling of use, provide a cleaning sensation, and ensure a suitable refreshing sensation. In addition, a method of suppressing the unpleasant taste and bitterness derived from the dentifrice base or active ingredient by adding a specific flavoring component is publicly known. Furthermore, in addition to suppressing the unpleasant taste and bitterness, flavorings have the functions of improving the refreshing feeling, improving the refreshing feeling, and imparting a transparent feeling that is preferred by young people.

[0003] Marine and ozone-based fragrances have a fresh, refreshing, transparent scent that evokes a specific air, wind, and water, and are widely used as fragrance ingredients in the field of cosmetics. However, while marine and ozone-based fragrances impart a unique fresh, refreshing, transparent scent, they also have a unique cosmetic feel (makeup smell) and bitterness, which significantly reduces their usability as flavors for oral preparations, and there have been issues with their use in the oral care field.

[0004] In Patent Document 1, a high-intensity sweetener, a disinfectant, and a flavoring component are contained, and the flavoring component is one or more selected from the group consisting of menthol, menthone, anethole, and cineole. By further containing other flavoring components, the discomfort and strange feeling caused by the disinfectant after vomiting is successfully suppressed. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-008429 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the method disclosed in Patent Document 1 was insufficient in suppressing the cosmetic feeling caused by the marine / ozone-based fragrance contained in the fragrance.

[0007] As a result of investigations to solve this problem, it was found that combining marine and ozone fragrances with cooling agents and floral fragrances has the effect of suppressing the cosmetic feeling during and after use of marine and ozone fragrances. The suppressive effect is not sufficient with either of these alone, but by combining both, it was found that in addition to suppressing the characteristic cosmetic feeling during and after use derived from marine and ozone fragrances, it also suppresses the bitterness during and after use, and gives a characteristic fresh refreshing feeling and transparency, which led to the present invention.

[0008] The present invention has been made in view of the above, and aims to provide an oral composition which reduces the bitterness peculiar to the marine / ozone-based fragrance and gives a feeling of fresh, dewy transparency reminiscent of air, wind and water by combining a marine / ozone-based fragrance, a cooling agent and a fragrance component having a floral fragrance.

[0010] By combining a marine / ozone-based fragrance, a cooling agent, and a fragrance component having a floral fragrance, the oral composition of the present invention reduces the bitterness characteristic of the marine / ozone-based fragrance, making it possible to provide an oral composition that gives a feeling of freshness and clarity reminiscent of air, wind, and water. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present invention relates to an oral composition.

[0012] The present invention is an oral composition comprising the following components (A), (B), and (C):

[0013] [Component (A)] The component (A) is one or more flavor components having a marine or ozone-based fragrance. By including the component (A), the oral composition can be endowed with the refreshing feeling, freshness, and transparency characteristic of marine or ozone fragrances.

[0014] In the technical field of fragrances, marine ozone fragrances are clearly distinguished from other fragrances. Marine ozone fragrances refer to, for example, transparent fragrances reminiscent of water, air, and wind, or the fragrance of melon and other gourd-like fruits, and are distinguished from so-called fruit fragrances and floral fragrances such as the component (C) described below. In addition, the component (B) described below and the component (D) such as mint and menthol have a simple refreshing sensation, while marine ozone fragrances do not have a refreshing sensation, but have a transparent and refreshing sensation reminiscent of, for example, water, air, and wind, and have a different scent tone.

[0015] Fragrance components having a marine or ozone-based fragrance include, for example, components having an aldehyde group or a ketone group, and components having an aldehyde group are preferred. Examples of components having an aldehyde group include the following helional (α-methyl-1,3-benzodioxole-5-propanal: formula (1)), floral ozone (4-ethyl-α,α-dimethylbenzenepropanal: formula (2)), cyclamen aldehyde (3-(4-isopropylphenyl)isobutyraldehyde: formula (3)), and melonal (2,6-dimethyl-5-heptenal: formula (4)). Examples of components having a ketone group include, for example, the following calone (7-methyl-2H-1,5-benzodioxepin-3(4H)-one: formula (5)). It is more preferable that the component (A) contains one or more compounds selected from the above group of compounds.

[0016] [ka]

[0017] The component (A) may be one fragrance component having a marine or ozone type fragrance, or a combination of two or more fragrance components.

[0018] [(B) Component] Component (B) is one or more selected from cooling agents. By including component (B), it is possible to reduce the cosmetic feeling of fragrance ingredients having a marine or ozone-based scent during and after use. In the present invention, the component (B) is clearly distinguished from the component (D) described below. The component (B) has a longer-lasting cool feeling than the component (D). In the present invention, menthol and carvone are excluded from the component (B).

[0019] Examples of cooling agents include menthol derivatives. Menthol derivatives refer to compounds having p-menthane (1-methyl-4-(1-methylethyl)cyclohexane) or its reduction in the structure, and more preferably have a carboxamide structure (amide bond). For example, menthyl lactate, menthyl monosuccinate, menthone glycerol acetal, ethyl-3-(p-menthane-3-carboxamide) acetate, N-ethyl-p-menthane-3-carboxamide, N-(4-cyanomethylphenyl)-2-isopropyl-5-methylcyclohexanecarboxamide, N-(2-(2-pyridinyl)ethyl)-2-isopropyl-5-methylcyclohexanecarboxamide, N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethyl ... Examples of the p-menthane-1-carboxamide include ethyl-3-(p-menthane-3-carboxamide) acetate, N-ethyl-p-menthane-3-carboxamide, N-(4-cyanomethylphenyl)-2-isopropyl-5-methylcyclohexanecarboxamide, N-(2-(2-pyridinyl)ethyl)-2-isopropyl-5-methylcyclohexanecarboxamide, and N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide are preferred.

These have a carboxamide structure and can further enhance the effect of reducing the cosmetic feeling after use.

[0022] [ka]

[0023] [ka]

[0024] Even more preferred from the viewpoint of the effect of reducing the cosmetic feeling after use are cooling agents having a carboxamide structure, such as ethyl-3-(p-menthane-3-carboxamide) acetate, N-ethyl-p-menthane-3-carboxamide, N-(4-cyanomethylphenyl)-2-isopropyl-5-methylcyclohexanecarboxamide, N-(2-(2-pyridinyl)ethyl)-2-isopropyl-5-methylcyclohexanecarboxamide, and N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide.

This allows the effect of reducing the cosmetic feel after use to be more effectively exhibited. The upper limit is preferably 0.5% by mass or less, or 0.3% by mass or less, more preferably 0.1% by mass or less, and even more preferably 0.005% by mass or less. This allows the refreshing feeling and transparency unique to the marine ozone-based fragrance to be more suitably prevented from decreasing.
