Description

This invention relates to, for example, a multifunctional oral cleansing composition that has multiple methods of use.

Traditionally, the prevention of oral diseases such as caries and periodontal disease has been achieved by cleaning and washing the oral cavity on a daily basis. One method for cleaning and washing the oral cavity is to apply a highly viscous toothpaste to a special brush and brush the teeth.

For example, a toothpaste composition for use in cleaning the oral cavity has been disclosed that contains a specified mass percentage of erythritol, reduced dextrin and/or indigestible dextrin, and water, with a mass ratio of erythritol to water ranging from 1 to 5.5 (see Patent Document 1).

However, such toothpaste compositions must be applied to a special brush and then used to brush the teeth, making cleaning and washing the teeth a time-consuming process. In response to this, mouthwashes are used, which are introduced into the mouth and rinsed to clean and wash the inside of the mouth. In addition, as a form of oral cleaning and washing, a method of brushing the tongue using a special tongue polish and brush has also been used. However, toothpastes that focus on cleaning and washing the teeth, tongue polishes that focus on brushing the tongue, and mouthwashes that lightly clean and wash the entire mouth have different roles, and consumers have no choice but to carry toothpaste, tongue polish, and mouthwash in order to use them properly, which is inconvenient.

<Multifunctional oral cleaning unit>
FIG. 1 is an explanatory diagram showing an example of a multifunctional oral cleaning unit 1.
The multifunctional oral cleansing unit 1 comprises a storage section 11 that stores a multifunctional oral cleansing composition 16, a release section 15 that releases the multifunctional oral cleansing composition 16 stored in the storage section 11 to the outside by operation from the outside, a transmission section 14 that sends the multifunctional oral cleansing composition stored in the storage section 11 to the release section 15, and a cover section 12 that covers the release section 15 and the transmission section 14.

The storage section 11 is cylindrical and hollow with a bottom, has an opening (not shown) at one end opposite the bottom, and contains a semi-liquid multifunctional oral cleansing composition 16 inside. The opening is closed by the transmission section 14. The storage section 11 is preferably transparent or translucent so that the consumer can visually check the amount of the multifunctional oral cleansing composition 16 contained therein.

The transmission section 14 is arranged to close the opening of the storage section 11, and includes a mechanism for sending the multifunctional oral cleansing composition 16 contained in the storage section 11 to the release section 15. For example, such a mechanism may include a hollow tube 17 that connects the internal cavity of the storage section 11 with the release section 15, and the semi-liquid multifunctional oral cleansing composition 16 contained in the storage section 11 is sucked up toward the release section 15 via the inside of the tube 17 by a suction operation from the release section 15.

The release section 15 has a mechanism for releasing the multifunctional oral cleansing composition 16 transmitted from the transmission section 14 to the outside. For example, such a mechanism can be a mechanism in which, when the top of the release section 15 is pressed (pushed), a certain amount of the multifunctional oral cleansing composition 16 is sucked up from the storage section 11 through the tube 17 and the transmission section 14 and released from an opening (not shown) provided in the release section 15.

The lid 12 is colorless, transparent, and cylindrical with a hollow interior having a bottom, has an opening (not shown) at one end opposite the bottom, is arranged to cover the release section 15 and the transmission section 14, and is configured to be detachable from the storage section 11. The lid 12 has a guide line 13 (guide display section) that indicates the amount of dilution solvent to be used when diluting the multifunctional oral cleaning composition 16 with a solvent such as water. In this embodiment, the guide line 13 is a red line that is arranged around the circumference of the lid 12, and the guide line 13 can be seen even from outside the colorless, transparent lid 12. In other words, the lid 12 corresponds to the dilution measuring section in this invention.

Therefore, the consumer can use the multifunctional oral cleaning composition 16 as a toothpaste and a tonguepaste by removing the lid 12 from the container 11, dripping or spraying a predetermined amount of the multifunctional oral cleaning composition 16 onto a commercially available toothbrush or tonguebrush and leaving it to stand, and brushing the teeth and tongue with the brush on which the multifunctional oral cleaning composition 16 is placed. In addition, the multifunctional oral cleaning composition 16 can be diluted at an arbitrary ratio by pouring a predetermined amount of the multifunctional oral cleaning composition 16 into the internal cavity of the lid 12 and pouring water using the guide line 13 as a guide, and the diluted multifunctional oral cleaning composition 16 can be rinsed in the mouth, and the multifunctional oral cleaning composition 16 can be used as a mouthwash. At this time, the amount of the multifunctional oral cleaning composition 16 to be poured corresponding to the dilution ratio may be written on the outer periphery of the container 11 or the lid 12, or on the outer box in which the multifunctional oral cleaning unit 1 is stored at the time of sale. For example, when preparing 10 ml of diluted multifunctional oral cleansing composition 16 using guide line 13, it may be described that if the top of release portion 15 of multifunctional oral cleansing unit 1 is pressed (pushed) once, 0.5 ml of multifunctional oral cleansing composition 16 is released from release portion 15, and if the top of release portion 15 is pressed (pushed) four times, it will be diluted five-fold (2.0 ml will be released and mixed with 8.0 ml of water), and if it is pressed ten times, it will be diluted two-fold (5.0 ml will be released and mixed with 5.0 ml of water).

FIG. 2 is an explanatory diagram showing an example of another embodiment of the multifunctional oral cleaning unit 100.
In the multifunctional oral cleansing unit 100, the capacity of the internal cavity of the storage part 11 is smaller than that of the storage part 11 of the multifunctional oral cleansing unit 1, and the amount released when the top of the release part 15 is pressed once is also smaller than that of the multifunctional oral cleansing unit 1. Even when the size of the multifunctional oral cleansing unit is different, the consumer can make 5-fold and 2-fold diluted multifunctional oral cleansing compositions 16 by appropriately changing the distance of the guide line 13 from the bottom of the lid part 12 or appropriately changing the number of times the top of the release part 15 is pressed (the number of times the push operation is performed). For example, when creating 10 ml of diluted multifunctional oral cleansing composition 16 using guide line 13, it can be written that if the top of the release portion 15 of the multifunctional oral cleansing unit 100 is pressed (pushed) once, 0.2 ml of multifunctional oral cleansing composition 16 will be released from the release portion 15, and if the top of the release portion 15 is pressed (pushed) 10 times, it will result in a 5-fold dilution (2.0 ml will be released and mixed with 8.0 ml of water), and if it is pressed (pushed) 20 times, it will result in a 2-fold dilution (5.0 ml will be released and mixed with 5.0 ml of water).

With the above-mentioned composition, a multifunctional oral cleansing composition that can be used as a mouthwash, tongue polish, and toothpaste can be provided.
The multifunctional oral cleaning composition of the present invention contains an oral cleanser and a thickener, and has a viscosity of 1000 to 5000 mPa·s. With this configuration, when not diluted, the composition can be maintained on a toothbrush or a tonguebrush, and can be suitably used as a toothpaste or tonguepaste, and when diluted at a predetermined ratio, the multifunctional oral cleaning composition is uniformly dispersed or dissolved in the solvent, and can be suitably used as a mouthwash. In other words, consumers can use different toothpastes, tonguepastes, and mouthwashes when they are out and about, without having to carry around different toothpastes, tonguepastes, and mouthwashes, and consumer satisfaction can be improved.

The multifunctional oral cleansing composition of the present invention has a viscosity of 50 to 200 mPa·s when the multifunctional oral cleansing composition is mixed with 80% by mass of water (5-fold diluted oral cleansing composition). This configuration allows consumers to smoothly hold the 5-fold diluted oral cleansing composition in their mouths and rinse, making it suitable for use as a mouthwash.

The multifunctional oral cleansing composition of the present invention has a viscosity of 100 to 1500 mPa·s when the multifunctional oral cleansing composition is mixed with 50% by mass of water (2-fold diluted oral cleansing composition). This configuration allows consumers to obtain a greater mouth cleansing effect than with a 5-fold diluted oral cleansing composition, and even with a 2-fold diluted oral cleansing composition, which has a lower dilution ratio, they can smoothly hold the composition in their mouth and rinse, making it more suitable for use as a mouthwash.

The multifunctional oral cleansing composition of the present invention also contains at least sodium cocoamphoacetate as an oral cleansing agent. With this configuration, the irritation-reducing effect of sodium cocoamphoacetate exerts a pH buffering effect in the weak acidic range, and the oral cavity can be protected from the irritation of alkaline or acidic substances.

In addition, the multifunctional oral cleansing composition of the present invention does not contain an abrasive. With this configuration, even when the multifunctional oral cleansing composition is diluted and used as a mouthwash, the consumer does not feel a rough sensation in the mouth caused by the abrasive, and the diluted multifunctional oral cleansing composition can be more suitably used as a mouthwash.

Furthermore, the multifunctional oral cleansing composition of the present invention does not contain any components present in the form of powder in the multifunctional oral cleansing composition, and does not contain any components that will separate from the multifunctional oral cleansing composition when added to an aqueous solvent and precipitate or float in the water. This configuration gives it a higher solubility in aqueous solvents than existing toothpastes, and it can be suitably used not only as a toothpaste and tonguepaste, but also as a mouthwash when diluted. Furthermore, consumers do not feel a rough feeling in the mouth due to the components contained in the powder, and the diluted multifunctional oral cleansing composition can be more suitably used as a mouthwash.

The multifunctional oral cleaning unit 1 of the present invention also includes a storage section 11 that stores the multifunctional oral cleaning composition 16, and a cover section 12 that includes a guide line 13 that indicates the amount of dilution solvent when diluting the multifunctional oral cleaning composition 16 with a dilution solvent such as water. With this configuration, when a consumer wants to use the multifunctional oral cleaning composition 16 as a mouthwash rather than a toothpaste or tonguepaste, the viscosity of the multifunctional oral cleaning composition 16 can be easily adjusted to a viscosity suitable for use as a mouthwash.

<Example>
A multifunctional oral cleansing composition was prepared by mixing the components shown in Table 1 in the ratios shown in Table 1, and used as an example.

The viscosity of the prepared multifunctional oral cleaning composition was measured. In this example and the comparative examples described herein, a B-type viscometer (manufactured by Toki Sangyo Co., Ltd., model number TVB-10R) was used to measure the viscosity. The viscosity value of the B-type viscometer changes depending on the measurement type (distinguished by model number, etc., roughly divided into high viscosity type and low viscosity type), rotor, and rotation speed settings, but the viscosity value of the measurement result decreases as the number assigned to the rotor (rotor No.) and the rotation speed increase. Also. In this specification, the measurement conditions refer to the rotor No. and the rotation speed setting conditions. In this example, a B-type viscometer, model number TVB-10R, manufactured by Toki Sangyo Co., Ltd. was used, but similar measurement results can be obtained even if a B-type viscometer, model number TVB-10H, manufactured by Toki Sangyo Co., Ltd., or a high-viscosity B-type viscometer manufactured by Brookfield Co., Ltd. is used. The viscosity of the multifunctional oral cleaning composition was 2660 mPa·s under the conditions of rotor No. 3 and rotation speed of 20 rpm. Furthermore, the multifunctional oral cleaning composition created could be placed on a commercially available toothbrush and tonguebrush without losing its shape, and was suitable for use as a toothpaste and tonguepaste.

The viscosity of the 5-fold diluted multifunctional oral cleaning composition, which was prepared by mixing 2 g of the prepared multifunctional oral cleaning composition with 8 g of purified water, was measured under the same measurement conditions as the prepared multifunctional oral cleaning composition, and was 120 mPa·s. The 5-fold diluted multifunctional oral cleaning composition was a slightly smooth liquid, and the shape was lost due to gravity on a commercially available toothbrush and tongue brush. It was possible to rinse it in a human mouth. The viscosity of the 2-fold diluted multifunctional oral cleaning composition, which was prepared by mixing 5 g of the prepared multifunctional oral cleaning composition with 5 g of purified water, was measured under the same measurement conditions as the prepared multifunctional oral cleaning composition, and was 780 mPa·s. The 2-fold diluted multifunctional oral cleaning composition was a gel, and the shape was lost due to gravity on a commercially available toothbrush and tongue brush. It was possible to rinse it in a human mouth. Furthermore, the 10-fold diluted multifunctional oral cleaning composition, which was prepared by mixing 1 g of the multifunctional oral cleaning composition with 9 g of purified water, was a smooth liquid and lost its shape due to gravity when placed on a commercially available toothbrush and tongue brush. In addition, no irritation was felt when placed in the oral cavity regardless of the dilution ratio. In addition, the refreshing feeling when placed in the oral cavity decreased as the dilution ratio increased. Therefore, the 5-fold diluted multifunctional oral cleaning composition can be suitably used as a general mouthwash, and the 2-fold diluted multifunctional oral cleaning composition can be suitably used as a mouthwash when a stronger mouthwash is required, such as when bad breath is a concern. Furthermore, the 10-fold diluted multifunctional oral cleaning composition, which has a higher dilution ratio, had an even lower refreshing feeling than the 5-fold diluted multifunctional oral cleaning composition, and was suitable for use as a mouthwash for children and the elderly.

2g of the multifunctional oral cleaning composition of the embodiment and 8g of purified water are put into a container, and the container is shaken horizontally 50 times, 100 times, and 150 times to confirm the dispersibility of the multifunctional oral cleaning composition in purified water.As a result, as shown in Fig. 3d, after shaking 150 times, the multifunctional oral cleaning composition is finely mixed in purified water.Therefore, the multifunctional oral cleaning composition of embodiment 1 has good dispersibility in water.

<Comparative Example 1>
4a is a photograph taken immediately after Comparative Example 1 was placed in a container together with purified water, FIG. 4b is a photograph taken after Comparative Example 1 was placed in a container together with purified water and the container was then shaken horizontally 50 times, FIG. 4c is a photograph taken after Comparative Example 1 was placed in a container together with purified water and the container was then shaken horizontally 100 times, and FIG. 4d is a photograph taken after Comparative Example 1 was placed in a container together with purified water and the container was then shaken horizontally 150 times.
A commercially available tongue polish was used as Comparative Example 1. When the viscosity of Comparative Example 1 was measured under the same measurement conditions as that of the multifunctional oral cleaning composition (Example 1), it exceeded the measurement limit of 10,000 mPa·s and could not be measured. When the rotor type was No. 5 and the measurement conditions were a rotation speed of 20 rpm, the viscosity was 23,420 mPa·s. When the rotor type was No. 3 and the measurement conditions were a rotation speed of 100 rpm for Comparative Example 1 in a 5-fold dilution state in which 2 g of Comparative Example 1 was mixed with 8 g of purified water, the viscosity was 70 mPa·s. When the viscosity of Comparative Example 1 in a 2-fold dilution state in which 5 g of Comparative Example 1 was mixed with 5 g of purified water was measured under the same measurement conditions as that of Example 1, the viscosity was 2,140 mPa·s. Therefore, Comparative Example 1 had a higher viscosity than the multifunctional oral cleaning composition (Example 1) in the undiluted state, 5-fold dilution state, and 2-fold dilution state. 2g of the tongue polish of Comparative Example 1 and 8g of purified water are put into a container, and the container is shaken horizontally 50 times, 100 times, and 150 times to observe the dispersibility of Comparative Example 1 in purified water. As a result, as shown in Fig. 4d, even after shaking 150 times, Comparative Example 1 remains in the purified water as large particles and is not mixed. Therefore, the multifunctional mouthwash composition of Comparative Example 1 has poor dispersibility in water.

<Comparative Example 2>
5a is a photograph taken immediately after Comparative Example 2 was placed in a container together with purified water, FIG. 5b is a photograph taken after Comparative Example 2 was placed in a container together with purified water and the container was then shaken horizontally 50 times, FIG. 5c is a photograph taken after Comparative Example 2 was placed in a container together with purified water and the container was then shaken horizontally 100 times, and FIG. 5d is a photograph taken after Comparative Example 2 was placed in a container together with purified water and the container was then shaken horizontally 150 times.
A commercially available gel-type dentifrice was used as Comparative Example 2. When the viscosity of Comparative Example 2 was measured under the same conditions as those of the multifunctional oral cleaning composition (Example 1), it exceeded the measurement limit of 10,000 mPa·s and could not be measured. When the rotor type was No. 4 and the measurement conditions were a rotation speed of 20 rpm, the viscosity was 10,040 mPa·s. Therefore, Comparative Example 2 had a higher viscosity than the multifunctional oral cleaning composition (Example 1) in an undiluted state. 2 g of the dentifrice of Comparative Example 2 and 8 g of purified water were put into a container, and the container was shaken horizontally 50 times, 100 times, and 150 times to observe the dispersibility of Comparative Example 2 in purified water. As a result, as shown in FIG. 5d, even after shaking 150 times, Comparative Example 2 remained in the purified water as large particles and was not mixed. Therefore, the dentifrice of Comparative Example 2 had poor dispersibility in water.

<Comparative Example 3>
6a is a photograph taken immediately after Comparative Example 3 was placed in a container together with purified water, FIG. 6b is a photograph taken after Comparative Example 3 was placed in a container together with purified water and the container was then shaken horizontally 50 times, FIG. 6c is a photograph taken after Comparative Example 3 was placed in a container together with purified water and the container was then shaken horizontally 100 times, and FIG. 6d is a photograph taken after Comparative Example 3 was placed in a container together with purified water and the container was then shaken horizontally 150 times.
A gel-type dentifrice on the market different from that of Comparative Example 2 was used as Comparative Example 3. When the viscosity of Comparative Example 3 was measured under the same conditions as that of the multifunctional oral cleaning composition (Example 1), it exceeded the measurement limit of 10,000 mPa·s and could not be measured. When the rotor type was No. 4 and the measurement condition of the rotation speed was 20 rpm, the viscosity was 7360 mPa·s. When the rotor type was No. 3 and the measurement condition of the rotation speed was 20 rpm for Comparative Example 1, which was in a 5-fold dilution state in which 2 g of Comparative Example 3 was mixed with 8 g of purified water, the viscosity was 240 mPa·s. When the viscosity of Comparative Example 3, which was in a 2-fold dilution state in which 5 g of Comparative Example 3 was mixed with 5 g of purified water, was measured under the same measurement conditions as that of Example 1, the viscosity was 1620 mPa·s. Therefore, Comparative Example 3 had a higher viscosity than the multifunctional oral cleaning composition (Example 1) in the undiluted state, 5-fold dilution state, and 2-fold dilution state. 2 g of the dentifrice of Comparative Example 3 and 8 g of purified water were put into a container, and the container was shaken horizontally 50 times, 100 times, and 150 times to observe the dispersibility of Comparative Example 3 in purified water. As a result, as shown in Figure 6d, even after shaking 150 times, Comparative Example 3 remained in the purified water as large particles and was not mixed. Therefore, the dentifrice of Comparative Example 3 had poor dispersibility in water.
