[0032] <2. Forms and uses of oral compositions> The composition can be used as a dentifrice such as a toothpaste, a liquid dentifrice, a lubricant dentifrice, a powder dentifrice, or a gel dentifrice, and is preferably a toothpaste or a gel dentifrice. The composition can be made into a striped dentifrice by combining two or more compositions containing pigments of different colors. The above ingredients may be contained throughout the entire striped dentifrice, and the two or more compositions containing different pigments may have the same or different compositions other than the pigments.

[0033] <3. Dosage Form> The dosage form of the oral composition can be appropriately selected depending on the mode of use and is not particularly limited, and examples of dosage forms include gel, paste, and liquid.

[0034] <4. Method for producing oral composition> The method for producing the oral composition is not particularly limited, and it can be prepared by any conventional method depending on the dosage form. For example, when the oral composition is used as a toothpaste composition, a method can be used in which the water-soluble components are prepared, and then the other components are mixed, and degassing (e.g., reduced pressure, etc.) is performed as necessary. The obtained toothpaste composition can be placed in a container to make a product. The shape and material of the container are not particularly limited, and containers used for conventional toothpaste compositions can be used, such as plastic containers made of polyethylene, polypropylene, polyethylene terephthalate, nylon, etc. [Example]

[0035] The present invention will be specifically described below with reference to examples and comparative examples. The present invention is not limited to the examples described below. Note that the numerical values ​​described in these examples (including the numerical values ​​in the following table) represent mass % unless otherwise specified.

[0036] <Examples 1 to 7> A toothpaste as an oral composition was prepared by a conventional method, having the composition shown in Table 1. The composition shown in Table 1 indicates the parts by mass of each component relative to 100 parts by mass of the total oral composition. All toothpastes were beautifully colored and did not noticeably discolor during storage.

[0037] [Table 1]

[0038] The compositions of the "fragrance compositions" in Table 1 are shown in Tables 2 and 3 below. The compositions shown in Tables 2 and 3 represent the parts by mass of each component relative to 100 parts by mass of the total amount of the fragrance composition. In the tables, "a% front end cut" means that the first a% is removed when the essential oil is fractionated, and "b% front end and tail end cut" means that the first b% and the last b% are removed when the essential oil is fractionated. The "fragrance composition A" blended in Examples 1 to 7 in Table 1 is the "fragrance A" in Tables 2 and 3. The compositions of flavors 1 to 9 and solvent 1 in Tables 2 and 3 are shown in Tables 4 to 33. Agents using any of fragrances B to X instead of fragrance composition A used in the Examples can also effectively achieve the effect of being beautifully colored and not showing noticeable discoloration during storage, just like the Examples.
