Description

TECHNICAL FIELD The present invention relates to an oral composition having an excellent effect of retaining a fragrance.

Conventional technology and its problems Conventionally, it has been practiced to add a fragrance to an oral composition in order to impart an aroma or flavor and to improve the feeling of use, but in this case, the effect of the fragrance is prolonged. It is desirable to add a fragrance retention agent for retention over time.

Traditionally, natural flavoring agents such as musk, oak moss, orris and synthetic flavoring agents such as coumarin and vanillin are often used as flavoring agents, and non-fragrance agents such as dialkyl phthalate, propylene glycol, benzyl alcohol and methyl dihydroabier are used. Tate and the like are known, but each of these conventional holding agents has a unique taste. For this reason, when these holding agents are added to the oral composition, there are off-taste, astringency, bitterness, and the like, which causes a problem in use feeling. Conventionally, there are almost no tasteless flavor retention agents suitable for oral compositions, and therefore tasteless retention agents that are suitable for use in oral compositions have been desired.

SUMMARY OF THE INVENTION In view of the above circumstances, the present inventors have made earnest studies on a retaining agent used in an oral composition, and as a result, jojoba alcohol, olein alcohol, 2-hexyldecanol, 2
-Octyldodecanol, isostearyl alcohol,
A higher aliphatic alcohol selected from octadecenol, eicosenol, dococenol and tetracocenol is used effectively as a retaining agent because of its excellent retention effect of perfume, and this type of higher aliphatic alcohol is tasteless and unscented. The composition does not impair the flavor even if it is added to the composition for oral use, does not cause a problem in use feeling, is not easily decomposed when added to the composition for the oral cavity, is stable, and has the effect of controlling the foaming of the surfactant. The present invention has been made to realize that the present invention is made.

Hereinafter, the present invention will be described in more detail.

Composition of the invention The oral composition according to the present invention is selected from jojoba alcohol, oleyl alcohol, 2-hexyldecanol, 2-octyldodecanol, isostearyl alcohol, and octadecenol, which is a component of jojoba alcohol, eicosenol, docosenol, and tetracosenol. One or more of the higher aliphatic alcohols mentioned above are contained as a flavoring agent. These higher aliphatic alcohols can satisfactorily retain various kinds of fragrances, and therefore, the fragrances used in the present invention are not particularly limited.
-Menthol, peppermint oil and the like are preferably used.

The blending amount of the above-mentioned higher aliphatic alcohol and perfume varies depending on the type of the composition and the like and is not necessarily limited, but the blending amount of the above alcohol is usually 0.001 to 5% of the entire composition.
(% By weight, the same applies hereinafter), particularly preferably 0.1 to 3%, and the amount of the fragrance compounded is 0.01 to 10% of the total composition,
In particular, it is preferably set to 0.1 to 3%. In this case, the ratio of the alcohol and the fragrance is 1: 9 to 7: 3 as a weight ratio,
In particular, the ratio of 3: 7 to 6: 4 is preferable from the viewpoint of effectively exhibiting the effect of the alcohol.

The composition for oral cavity of the present invention is prepared as a toothpaste, mouthwash, etc. In this case, the components usually used can be blended depending on the kind, dosage form and the like.

For example, in the case of toothpaste, dibasic calcium phosphate,
Abrasives such as calcium carbonate, calcium pyrophosphate, insoluble sodium metaphosphate, amorphous silica, crystalline silica, aluminosilicate, aluminum oxide, aluminum hydroxide, resin, carboxymethyl cellulose sodium, hydroxyethyl cellulose, alginate, carrageenan, gum arabic , Binders such as polyvinyl alcohol, polyethylene glycol, sorbitol,
Thickeners such as glycerin and propylene glycol, sodium lauryl sulfate, sodium dodecylbenzene sulfonate, hydrogenated coconut fatty acid monoglyceride sodium monosulfate, sodium lauryl sulfoacetate, sodium lauroyl sarcosinate, N-acyl glutamate, lauryl diethanol amide , Sucrose fatty acid ester and other surfactants, saccharin sodium, stevioside, neohesperidyl dihydrochalcone, glycyrrhizin, perillartine, sweeteners such as p-methoxycinnamic aldehyde and preservatives may be added. Further, in mouthwashes such as mouthwash and the like, components suitable for the properties of the product are appropriately mixed.

Furthermore, in the oral composition, chlorhexidine salt, dextranase, mutanase, sorbic acid, alexidine, hinokitiol, cetylpyridinium chloride,
Compound active ingredients such as alkylglycine, alkyldiaminoethylglycine salt, allantoin, ε-aminocaproic acid, tranexamic acid, azulene, vitamin E, water-soluble primary or secondary phosphate, quaternary ammonium compound, sodium chloride You can also

The higher aliphatic alcohol has a good fragrance-retaining effect as described above, but when used in combination with a surfactant, the foaming amount can be adjusted without adjusting the compounding amount of the surfactant. . Therefore, in the present invention, in addition to the purpose of retaining a fragrance, it can be suitably used for the purpose of adjusting the foamability of a composition for oral cavity containing a surfactant, such as dentifrice.

The composition for oral cavity of the present invention can be produced by adopting an ordinary method depending on its type and the like, but in this case, the order of addition of the alcohol and the fragrance is not limited, and for example, the alcohol is preliminarily added to the fragrance. The alcohol may be mixed with other components, or the alcohol may be added and mixed separately from the fragrance.

Effect of the Invention The oral composition of the present invention, by blending the higher aliphatic alcohol, the fragrance is well retained, the effect of the fragrance is retained for a long time, and the alcohol is tasteless and unscented. It is stable, does not cause off-taste, astringency, and bitterness, and has a good effect of adjusting the foaming of the surfactant.

Next, the present invention will be specifically described by showing experimental examples and examples and comparative examples, but the present invention is not limited to the following examples.

[Experimental Example] The following three kinds of samples were prepared, placed in a petri dish (diameter 90 mm, height 20 mm) with the same diameter, left at room temperature with the lid open, and the weight was measured to leave the fragrance. The rate was evaluated. The results are shown in the drawing. In the figure, A is the result of the present invention, B is the result of comparative fragrance 2, and C is the result of comparative fragrance 1.

As a result of the preliminary experiment, almost no weight loss was observed with benzyl alcohol and jojoba alcohol over time, so it was considered that the weight loss of the samples No. 2 and No. 3 below was due to the volatilization of the fragrance.

Sample No.1 (Comparative fragrance 1) Toothpaste 5.00g No.2 (Comparative fragrance 2) Toothpaste 5.00g + Benzyl alcohol 5.00g No.3 (Invention fragrance) Toothpaste 5.00g + Jojoba alcohol 5.00g From the results, it was confirmed that jojoba alcohol has an excellent fragrance-retaining effect.

[Examples 1 to 5 and Comparative Example] A toothpaste having the following formulation containing alcohol shown in Table 1 was prepared, and the degree of foaming was organoleptically evaluated by 10 panelists according to the criteria of 5 stages shown in Table 1. .

Toothpaste formulation Aluminum hydroxide 42.0% Silica anhydride 2.0 Propylene glycol 2.5 Sodium alginate 0.4 Carrageenan 0.6 Paraben 0.02 Sorbitol 35.0 Sodium lauryl sulphate 1.0 Sodium saccharin 0.1 Peppermint flavors 0.4 Alcohol 0.3 Water 100.0% remaining From the results shown in Table 1, it is recognized that 2-hexyldecanol, 2-octyldodecanol and isostearyl alcohol have an effect of suppressing foaming.
