Description

Toothpaste Composition

The present invention relates to a dentifrice composition which is prevented from spilling liquid from the mouth at the time of brushing, imparts freshness, and has excellent usability.

In the feeling of use of the composition for oral cavity, especially the dentifrice composition, the shedding of the preparation that bubbles or liquids fall out of the mouth not only lowers the effect of its use, but is also easily perceived as an unpleasant feeling, and the mouth is clean after brushing. It is also important to give the feeling of clean and refreshing effect.

In the toothpaste composition, an abrasive, a surfactant, a humectant, a caking agent, etc. are usually blended, and anionic surfactants, etc., are used for securing foaming, cleaning properties, etc. as the surfactant, and various water-soluble polymer materials as caking agents. It is used for the purpose of maintaining this moderate viscosity, shape retention, and the like. However, if the toothpaste composition is used to brush the teeth (the brushing time is usually about 3 minutes), even if the foam can be brushed without falling out of the mouth at the start, the foam gradually starts to fall out of the mouth as time passes. Liquid spilling may occur, and there was room for improvement in obtaining a dentifrice composition having a satisfactory feeling of brushing and satisfactory feeling by preventing liquid spillage.

On the other hand, carbonates, such as sodium hydrogencarbonate, are used for various uses as a compounding component for oral compositions, such as a toothpaste, and the technique regarding the compounding of hydrogencarbonate is specifically proposed by patent documents 1-7.

Japanese Patent Laid-Open No. 8-333228 Japanese Patent Laid-Open No. 9-132517 Japanese Patent Laid-Open No. 11-1418 Japanese Patent Laid-Open No. 2002-104945 Japanese Patent Laid-Open No. 2002-302450 Japanese Patent Publication No. 2009-137908 International publication 2013/094312

This invention is made | formed in view of the said situation, and an object of this invention is to provide the toothpaste composition which prevents liquid dripping from the mouth at the time of tooth brushing, gives a freshness, and is excellent in usability.

MEANS TO SOLVE THE PROBLEM As a result of earnestly examining in order to achieve the said objective, the present inventors mix | blend a specific amount or more with anionic surfactant to a toothpaste composition, mix | blend a specific amount or more with xanthan gum, and further mix | blend a hydrogen carbonate below a specific amount. The present invention has been found to prevent bubbles and liquids from falling out of the mouth during brushing, to satisfactorily impart freshness, and to appropriately suppress irritation, thereby providing excellent usability. Reached.

Moreover, in this invention, when further mixing sodium polyacrylate or sodium alginate, it also discovered that the dispersibility of the preparation in an oral cavity improves, and the usability improves more.

That is, in this invention, it mixes and blends (A) 1.4-2.5 mass% of anionic surfactants, 1.4-2.5 mass% of (B) xanthan gum, and 0.1-5 mass% of (C) hydrogencarbonate, Especially (B) By using a relatively large amount of xanthan gum, foaming performance can be improved, liquid spillage at the time of brushing can be prevented, satisfactory freshness can be provided, and stimulation can be suppressed.

In this case, in order to improve the feeling of use of the dentifrice composition, when (A) anionic surfactant is blended in a relatively large amount for the purpose of improving foaming, even if foaming can be improved, brushing is started immediately. Although bubbles may start to fall from the mouth and the liquid may fall off, (B) By using xanthan gum in combination with a specific amount or more, the spillage of the liquid from the mouth at the time of brushing can be effectively prevented and continued for a long time. Could have done. In this case, however, the combination of the components (A) and (B) caused another problem that the freshness after rinsing the mouth at the time of brushing was impaired and the feeling of use was lowered. Therefore, further study was conducted, and by adding the (C) hydrogen carbonate salt in a specific amount or less, it was possible to prevent the liquid from flowing without causing the problem of neat deterioration as described above. In addition, although hydrogen carbonate has a feeling of improving the feeling of use, blending (A) component more than a certain amount and blending too much hydrogen carbonate increases the irritation, but it is not limited to 3 of (A), (B) and (C) components. By combining the dogs in specific amounts, surprisingly, prevention of liquid spillage and the provision of freshness were both achieved, improving the feeling of use and providing a special effect.

In dentifrice compositions, xanthan gum, which may affect spinnability, is often used in an amount of less than 1% by mass, but in the present invention, by using 1.4% by mass or more of xanthan gum Unexpectedly, the above-described effects were exhibited.

As also shown in Examples described later, the dentifrice composition containing the components (A), (B) and (C) of the present invention has a liquid from the mouth even after 1 minute or more than 2 minutes has passed after the start of brushing. Spilling was suppressed, and it was excellent in the absence of liquid spillage, and also excellent in the freshness and the absence of irritation. On the other hand, as shown in the comparative example, when omission of any one of (A), (B) and (C) components, or when the compounding amount of any one is inadequate even if three are blended, the effect of the present invention is inferior lost.

Therefore, this invention provides the following toothpaste composition.

ADVANTAGE OF THE INVENTION According to this invention, the dentifrice composition which prevents liquid dripping from the mouth at the time of brushing, imparts freshness, and is excellent in usability can be provided.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail. The toothpaste composition of this invention contains (A) anionic surfactant, (B) xanthan gum, and (C) hydrogencarbonate in a specific amount, respectively.

(A) As anionic surfactant, N-acyl taurate, such as alkyl sulfate, (alpha)-olefin sulfonate, hydrogenated coconut fatty acid monoglyceride monosulfate, lauryl sulfo acetate, N-methyl-N- acyl taurine salt, etc. And acylamino acid salts such as acyl sarcosine salt and N-acyl-L-glutamate. These can be used 1 type or in 2 or more types. Among them, in terms of foaming, anionic surfactants containing sulfonic acid groups are preferable, and alkyl sulfates and α-olefinsulfonates are more preferable. Examples of the salts include sodium salts, potassium salts and ammonium salts, and sodium salts are particularly preferred.

The alkyl sulfate preferably has 10 to 14 carbon atoms, and specific examples of the alkyl sulfate include sodium lauryl sulfate and sodium myristoyl sulfate.

As the α-olefin sulfonate, alkali metal salts such as sodium and potassium of α-olefin sulfonic acid having 14 to 16 carbon atoms can be used, and among them, α-olefin sulfonate having 14 carbon atoms, in particular sodium salt (common name; tetradecene Sodium sulfonate) is preferred. These can obtain the commercial item which can be used for the formulation for oral use, For example, the brand name "K Liporan PJ-400CJ" by Lion Specialty Chemicals Co., Ltd. can be used.

Moreover, the anionic surfactant which does not have a sulfonic acid group, especially acylamino acid salts, such as N-acyl-L-glutamic acid salt, may be weakly foamed by combining with (B) and (C) component, In this respect, As the component (A), anionic surfactants containing sulfonic acid groups, in particular alkyl sulfates and α-olefinsulfonates are preferred.

(A) The compounding quantity of an anionic surfactant is 1.4-2.5% (mass% or less) of the whole composition, Preferably it is 1.6-2.0%.
