Description

Pump type container for toothpaste and toothpaste composition

The present invention relates to a pump-type toothpaste container and a toothpaste composition, and more particularly, to a pump-type toothpaste container having a structure for pumping toothpaste contained in the container and discharging it through a nozzle, and to a toothpaste composition for housing in the container .

In general, paste-type toothpaste is commercialized by being put in a tube-type soft container. In some cases, due to the high viscosity of toothpaste, the tube-type toothpaste container has a problem of pressing the container with strong force to squeeze the toothpaste, and the remaining amount is easily discharged. There was no discomfort.

In toothpaste, sorbitol is mainly used as a humectant and moisturizer. Sorbitol is used in a state of about 70% aqueous solution, but it has a property of rapidly converting into a solid as the water dries. In particular, since the toothpaste contains a solid as an abrasive, it can be easily solidified upon contact with air. In consideration of this problem, recent attempts have been made to promote convenience of use by consumers by applying a dip tube pump type container widely used for shampoo or body wash to toothpaste.

Such a dip tube pump type container has the advantage of being excellent in versatility and easy to introduce due to a low unit price. When used as a container, as the use time increases, the viscosity increases as the toothpaste dries, requiring a greater force to discharge gradually. There was a problem of solidification and wear of the piston or nozzle of the pump.

On the other hand, in order to use the dip tube pump type container, the toothpaste must flow down to the bottom of the pump by its own weight or gravity within the container. However, the toothpaste of the highly elastic formulation flows down relatively slowly, causing a problem in that the remaining amount of the toothpaste in the container is excessive. Japanese Patent Laid-Open Publication No. 2009-215176 suggests an alternative delamination toothpaste container including an outer layer forming an exterior and an inner layer accommodating the contents, but the volume of the inner layer for accommodating the toothpaste when the actual toothpaste is discharged During this contraction, a stenosis phenomenon occurred in which the contracted inner layer blocked the entrance to the container, and a significant amount of stored toothpaste could not communicate with the pump dispenser and remained.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a pump-type toothpaste container according to Embodiment 1 of the present invention.

Referring to FIG. 1 , the pump-type toothpaste container 1 according to Embodiment 1 of the present invention includes a container body 10 , a nozzle 20 , an airless pump 30 and a tube 40 .

The container body 10 includes an outer layer 11 and an inner layer 12, and may include a storage space therein to accommodate the toothpaste (P). Specifically, the outer layer 11 forms the exterior of the container and may have a ventilation portion 16 , and the inner layer 12 is accommodated in a peelable manner inside the outer layer 11 , and toothpaste (P) A storage space may be provided therein to accommodate it. That is, the container body 10 may be a delamination container.

The container 1 may be erected vertically on the ground, and for this purpose, the container body 10 may have a flat structure in which part or all of a surface in contact with the ground is vertically erected on the ground. In a state in which the container 1 includes all of the container body 10, the nozzle 20, the airless pump 30, the tube 40, and the toothpaste P accommodated therein, in particular, the capacity of the toothpaste P in the container The shape and size of the container body 10 may not be limited as long as it can be erected vertically on the ground regardless of may be prismatic. Preferably, the container body 10 may have a conical shape, and more preferably, in consideration of the center of gravity of the container body 10 , at least a portion of the body may be in the form of a downward beam.

The container body 10 may be manufactured through multi-layer blow molding of a thermoplastic resin. Multi-layer blow molding is a molding method in which a thermoplastic resin is injected into a mold of a pre-prepared shape and stretched in the shape of the mold by controlling the temperature. A multilayer structure of the outer layer 11 and the inner layer 12 may be formed by sequentially blowing hot air into the resins to form a multilayered structure. In the case of multi-layer blow molding, the resin and air injection part may be molded in the shape of the container inlet 13 . That is, the outer layer 11 and the inner layer 12 may form the container inlet 13 in a state of being coupled to each other, and may be peeled off from the remaining portion other than the container inlet 13 . Therefore, it communicates with the storage space of the inner layer 12 through the container inlet 13 , and may not communicate with the interior of the outer layer 11 . The container inlet (13) may be used for injection and dispensing of the toothpaste (P), and the container body (10) may be used to engage the cap (14). The toothpaste P is stored inside the container body 10 only through the container inlet 13 and may be discharged to the outside, and the cross section of the container inlet 13 may be circular.

The outer layer 11 forms the exterior of the container 1 , and may have a ventilation portion 16 . The outer layer 11 may be made of one or more selected from the group consisting of polypropylene, high-density polyethylene, polycarbonate, and polyethylene terephthalate, and may have a hardness enough to allow the container 1 to stand perpendicular to the ground. Preferably, the outer layer 11 may have a relatively higher hardness than the inner layer 12 . In addition, the outer layer 11 may be opaque so that part or all of the shape of the inner layer 12 may not be transmitted. Through this, it is possible to prevent a change in the quality of the toothpaste due to transmission of external ultraviolet rays, and to hide the deformation of the inner layer 12, which will be described later, from the outside, thereby improving the aesthetics of the appearance.

The ventilation unit 16 may be formed on one surface of the outer layer 11 , preferably on the bottom surface of the container 1 in contact with the ground, to allow air to communicate inside and outside the outer layer 11 . In the case of discharging the toothpaste (P) inside the inner layer 12 receiving space through the airless pump 30 to be described later, the outside air enters the space between the outer layer 11 and the inner layer 12 through the ventilation unit 16. It can be injected, and it is possible to achieve a smooth discharge operation and stable discharge of the toothpaste without contacting the toothpaste P accommodated in the storage space inside the inner layer 12 with external air. More specifically, if the ventilation unit 16 is formed only on the outer layer 11 so as to inject external air into the space between the outer layer 11 and the inner layer 12 through the outer layer 11, its shape and size and The number may not be limited. Preferably, the ventilation part 16 may be formed in the form of a slit in the outer layer 11 through a pinch-off process during multi-layer blow molding of the container body 10 . The pinch-off process cuts the overlapping portion of the outer layer 11 from the lower portion where the outer layer 11 and the inner layer 12 are pinched together during multi-layer blow molding, thereby slitting the ventilation portion 16 at the lower end of the outer layer 11. It may be formed in the form.

The bottom surface on which the outer layer 11 of the container 1 is in contact with the ground can be divided into one area and the other area in which the ventilation part 16 is formed, and the remaining area in which the ventilation part 16 is not formed is a protrusion (not shown). ), it is possible to smoothly inject external air through the ventilation unit 16 . The protrusion may allow the bottom surface of the container 1 to be spaced apart from the ground so that external air may be smoothly injected into the space between the outer layer 11 and the inner layer 12 through the vent 16 . In particular, by spaced apart from the ground one area in which the ventilation part 16 is formed, external air can be smoothly injected through the ventilation part 16 even when the ground is wet. In addition, one area in which the ventilation part 16 is formed is formed to be concave toward the inner direction of the container 1 compared to the remaining areas in which the ventilation part 16 is not formed, so that the ventilation part 16 is spaced apart from the ground. External air may be smoothly injected into the space between the outer layer 11 and the inner layer 12 through the base 16 .

The inner layer 12 is accommodated so as to be peelable inside the outer layer 11, and a storage space may be provided therein to accommodate the toothpaste (P). The inner layer 12 may be a separate layer formed separately from the outer layer 11 according to the multi-layer blow molding of the container body 10 . The inner layer 12 may form the container inlet 13 in a state of being coupled to the outer layer 11 , and may be peeled off from the remaining portion other than the container inlet 13 .

Referring to FIGS. 3 and 4 , the inner layer 12 may include a storage space therein, and the volume may be reduced according to the capacity of the toothpaste P accommodated therein. That is, part or all of the inner layer 12 may come into contact with the inner wall of the outer layer 11 depending on the amount of toothpaste P accommodated in the storage space, and according to the discharge of the toothpaste P, the inner layer 12 As the volume decreases, a portion of the inner layer 12 may be peeled off from the inner wall of the outer layer 11 . Accordingly, the inner layer 12 may be made of a material whose volume can be changed according to the capacity of the toothpaste P accommodated in the storage space. Preferably, the inner layer 12 has a lower hardness than the outer layer 11 , so that a change in volume can easily occur compared to the outer layer 11 . For example, the inner layer 12 may be made of one or more selected from the group consisting of ethylene vinyl alcohol, low density polyethylene, and nylon.

The inner layer 12 can be combined with the cap 14 and the airless pump 30 through the container inlet 13, and stores the toothpaste P into the storage space inside through the container inlet 13, and the tube It only discharges through the inlet of the Therefore, the toothpaste P accommodated in the storage space of the inner layer 12 may be stored and discharged without contact with external air, thereby storing the toothpaste P in a non-dry state. In addition, long-term discharge stability can be secured by preventing abrasion inside the nozzle 20 and the airless pump 30 due to solidification of the abrasive in the toothpaste P, which may occur when the toothpaste P is dried.

The pumping pressure of the airless pump 30 may be 1.5 to 4.0 kgf. The pumping pressure may be the same as an external force required to press the nozzle 20 connected to the airless pump 30 in the vertical downward direction. As described below, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to an embodiment of the present invention may be 10,000 to 70,000 cP, and the minimum pumping pressure required to pump the toothpaste of this viscosity may be 1.5 kgf. By using the container body 10 including the outer layer 11 and the inner layer 12, the maximum pumping pressure required for pumping toothpaste may be 4.0 kgf. In addition, by using the container body 10 including the outer layer 11 and the inner layer 12, the pumping pressure is the same even if the remaining amount of the toothpaste (P) contained in the container 1 decreases according to the discharge and use of the toothpaste. can be maintained within the range.

A single pumping amount of the airless pump 30 may be 0.5 to 3.5 g. The pumping amount may be the same as the amount of toothpaste discharged through the discharge port 21 as the nozzle 20 is pressed all the way in the vertical lower direction at a time by an external force.

The airless pump 30 may be coupled to the tube 40 through the lower end of the housing 31 forming the exterior of the pump. Referring to FIG. 1 , the tube 40 may be inserted and fixed through the lower end of the housing 31 . The outer wall of the tube 40 may be inserted and fixed to fit between the inner wall of the lower end of the housing 31 . Although not shown, the tube 40 is inserted to the lower end of the valve provided inside the housing 31 and is in close contact, so that the toothpaste P can be supplied to the airless pump 30 only through the tube 40 .

The tube 40 may be located inside the receiving space in the inner layer 12 and may communicate with the airless pump 30 to communicate the toothpaste. Specifically, one end of the tube 40 is located inside the receiving space and can be in contact with the toothpaste (P) accommodated in the receiving space, and the other end is connected to the discharge path of the airless pump 30 to accommodate the receiving space. It is possible to communicate the toothpaste (P) accommodated in the airless pump (30). More specifically, the other end of the tube 40 may be fixed by being inserted into the housing 31 of the airless pump 30 .

In the case of the pump-type toothpaste container according to Embodiment 1 of the present invention, by positioning the tube 40 as described above, the volume of the inner layer 12 is reduced according to the discharge and use of the toothpaste P, so that the inner layer 12 is Even in the case of contraction, the amount of toothpaste P pumped through the airless pump 30 can be constantly maintained by securing a space of at least the cross-sectional area of the tube 40 in the container inlet 13 . Therefore, the material of the tube 40 is harder than the inner layer 12, so it should be able to maintain its shape and communicate the toothpaste P despite the pressure caused by the contraction of the inner layer 12. For example, the tube 40 may be made of one or more selected from the group consisting of polypropylene, high density polyethylene, polycarbonate, and polyethylene terephthalate, but is not limited thereto. The cross-section of the tube 40 may be circular, but is not limited thereto.

The length of the tube 40 may be 1/5 to 4/5 of the depth direction length of the inner layer 12 receiving space. That is, by using the point that the volume of the inner layer 12 is reduced according to the discharging of the toothpaste, one end of the tube 40 may not touch the bottom of the inner layer 12 receiving space. As will be described later, the viscosity of the toothpaste that can be used in the pump-type toothpaste container according to an embodiment of the present invention may be 10,000 to 70,000 cP, and the tube 40 required to pump the toothpaste of this viscosity without stenosis of the inner layer. The minimum length may be 1/10 of the depth direction length of the storage space. By using the point that the volume of the inner layer 12 is reduced according to the discharge of the toothpaste, the length of the tube 40 may not exceed 9/10. By using the tube 40 with a length that satisfies the above range, it is possible to prevent stenosis of the container inlet 13 due to the contraction of the inner layer 12, and to maintain the pumping pressure and one pumping amount that satisfy the above-mentioned range. can Preferably, the length of the tube 40 may be 1/10 to 9/10 of the depth direction length of the inner layer 12 receiving space.

The width of the tube 40 may be 3 to 7 mm for a toothpaste composition having a low viscosity of 10,000 to 25,000 cP, and may be 5 to 9 mm for a toothpaste composition having a high viscosity of 25,000 cP or more. The thickness of the tube 40 may be 0.5 to 1.5 mm.

As described above, in the present embodiment 1, in the pump-type toothpaste container 1 of the delamination type having the airless pump 30, by inserting and fixing the tube 40 into the lower end of the housing 31, the toothpaste (P) It is possible to achieve stable discharge of the toothpaste (P) by preventing the stenosis of the container inlet 13 due to the volume reduction of the inner layer 12, even if it is used by discharging.

Hereinafter, examples relating to a high-viscosity toothpaste composition for use in a pump-type toothpaste container according to an embodiment of the present invention will be described. The toothpaste composition according to this embodiment has a viscosity of 25,000 to 70,000 cP, and although it is difficult to use in a conventional dip tube pump type container, it is suitable for the pump type toothpaste container according to the present invention.

The toothpaste composition according to an embodiment of the present invention may include water, a thickener, an abrasive, and a polyol. In addition, the toothpaste composition may further include a solubilizer, a flavoring agent, a sweetener, a medicinal agent, a pH adjuster, a preservative, a binder, a foaming agent, etc. depending on the purpose of use.

Water may be used for toothpaste compositions in the art. For example, it may be one or more selected from the group consisting of purified water, aloe vera extract, witch hazel extract, cucumber extract, lemon extract, and lavender extract, but is not limited thereto.

Water may be included in an amount of 25 to 50% by weight based on 100% by weight of the toothpaste composition. When water is included in an amount of less than 25% by weight, the loosening property of the toothpaste in the oral cavity is significantly lowered and the sagging of the lump is severe when the composition is discharged. significantly lowered.

The thickener may adjust the viscosity of the toothpaste composition to 25,000 to 70,000 cP, which is a viscosity suitable for loading and discharging the pump-type toothpaste container of the present invention. The thickener may be an organic or inorganic binder. As the organic thickener, one or more organic polymers selected from xanthan gum, cellulose gum, gum arabic, locust bean gum, alginic acid and alginate may be used. As the inorganic thickener, silica for thickening, bentonite, etc. may be used, but silica for thickening may be preferably used.

The silica for thickening may include precipitated silica or colloidal silicon dioxide, and ^{may mean a BET specific surface area of 500 m 2} /g or more. Precipitated silica is prepared by mixing sand and caustic soda, dissolving it in water, performing a sol-gel reaction, and then adding sulfuric acid, and adjusting the sol-gel reaction time and conditions to obtain a BET specific surface area of ^{500 m 2 /g or more} It can be prepared with the silica for the thickening having. Colloidal silicon dioxide can be produced by spraying silicon tetrachloride and then burning it. The silica for thickening has a higher specific surface area compared to silica for polishing, so it can absorb more water, thereby increasing the viscosity of the composition over time. In addition, the silanol group (-SiOH) contained in the silica for increasing use strongly interacts with the adjacent silanol group through hydrogen bonding, thereby increasing the elasticity of the toothpaste and improving shape retention. Silica for thickening may be included in an amount of 0.1 to 8.0% by weight based on 100% by weight of the toothpaste composition. When the amount of silica for thickening is added less than 0.1% by weight, the shape retention of the toothpaste cannot be improved, and when used in excess of 8% by weight, the shape retention is improved, but the discharge pressure is increased due to excessive increase in viscosity to prevent discharge. do.

The solubilizer may solubilize a material having low solubility in water, and may be used in a toothpaste composition in the art. For example, polyglyceryl-3 methylglucose distearate, oleth-10, oleth-10/polyoxyl 10 oleylester NF, cereth-10, PEG-8 laurate, cocamite MEA, polysorbate 60 NF, polysorbate 60, polysorbate 80, isosteareth-20, polysorbate 80 NF, PEG-20 methylglucose sesquistearate, ceteareth-20, oleth-20, steareth-20, It may be one or more selected from the group consisting of steareth-21, cereth-20, poloxamer 184 and poloxamer 407, but is not limited thereto.

The abrasive has a function of removing plaque in the oral cavity and may be used in a toothpaste composition in the art. For example, it may be one or more selected from the group consisting of hydrous silicon dioxide, silicon dioxide, precipitated silica, calcium carbonate, polyethylene, cellulose, and zeolite, but is not limited thereto. The abrasive may be contained in an amount of 5 to 18% by weight based on 100% by weight of the toothpaste. If the abrasive is less than 5% by weight, the organic binder may cause a slippery feeling when brushing, and the freshness may decrease. .

The polyol may prevent abrasion of the nozzle and the pump due to the abrasive in the toothpaste composition, and prevent hardening at the outlet in contact with air in the toothpaste container. The polyol may be used in a toothpaste composition in the art. For example, it may be one or more selected from the group consisting of ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol and glycerin, but is not limited thereto. The polyol may include at least one of liquid and solid polyols, and sorbitol may be used as the solid polyol. The polyol may be contained in an amount of 2 wt% to 70 wt% based on 100 wt% of the toothpaste. The toothpaste composition according to this embodiment may be used by mixing liquid polyol and sorbitol, and solid sorbitol may be mixed in the form of an aqueous solution. The ratio of sorbitol (70% aqueous solution) and polyol may be 1:0.1 to 1:4. As such, when the liquid and solid polyols are mixed and used, the liquid polyol is hydrolyzed to the solid polyol, so that evaporation of water in the mixture is minimized, and even when water evaporates, it is possible to prevent a strong network from being formed between the polyols. Therefore, when the solid polyol is used alone, it is possible to solve the problem of hardening of the discharge port in contact with air in the toothpaste container.

The flavoring agent remains in the oral cavity and continuously emits fragrance, and at least one selected from the group consisting of mint such as peppermint and spearmint, eugenol, methyl salicylate, winter green extract, melon extract, strawberry extract, and orange extract. However, the present invention is not limited thereto.

Medicinal agents can be added for oral hygiene, and ingredients effective in preventing tooth decay, remineralization, gum disease, tartar deposition, and whitening can be used. Compounds capable of supplying fluoride ions, such as sodium fluoride, sodium monofluorophosphate and tin fluoride, may be used as medicinal agents used for the purpose of preventing tooth decay. Remineralizing agents can also act as a caries preventative. Remineralization is to regenerate and restore hydroxyapatite, which is a major component of teeth. One containing an anion may be used. For example, hydroxyapatite, dicalcium phosphate, calcium chloride, casein phospeptide, calcium glycerophosphate, monosodium phosphate, dibasic sodium phosphate, trisodium phosphate, monobasic potassium phosphate, dipotassium phosphate and dibasic It may be at least one selected from the group consisting of tri-potassium phosphate.

Polyacrylic acid is a -COOH functional groups in a condition that the pH value of 4 to 10 -COO ^- a polymer, which may have an elasticity to put into lead to electrostatic repulsion. Polyacrylic acid has very high elasticity compared to polymers commonly used in toothpastes such as cellulose gum and xanthan gum. Accordingly, the toothpaste further comprising polyacrylic acid or a pharmaceutically acceptable salt thereof may have elasticity as well as viscosity. The toothpaste composition further comprising polyacrylic acid or a pharmaceutically acceptable salt thereof can improve the shape retention of the toothpaste, but at low viscosity, the flowability is lowered and the remaining amount is increased, so its use is limited in the dip pump container, and the above-described practice It may be applied to a pump-type toothpaste container such as an example to provide improved shape retention.

Polyacrylic acid or a pharmaceutically acceptable salt thereof may be included in an amount of 0.2 wt% to 1.5 wt% based on 100 wt% of the composition. When polyacrylic acid or a pharmaceutically acceptable salt thereof is used in an amount of less than 0.2% by weight, the toothpaste does not improve shape retention, and when used in an amount of more than 1.5% by weight, the viscosity and elasticity increase to increase the ejection pressure to lower the ejection stability. do.

Experimental Example 1. Viscosity of the toothpaste composition

The toothpaste compositions prepared in Preparation Examples and Comparative Examples were rotated 5 times at 20 rpm using a Brookfield viscometer RVT type at 25° C. using spindles 5 to 7, and then the initial viscosity value (cP) was measured. After the toothpaste composition was sealed and stored for 1 month, the viscosity value (cP) over time was measured in the same way, and the results are shown in Table 3 below.

The toothpaste composition according to the present preparation achieved a high viscosity of 25,000 cP or more based on the initial viscosity including silica for increasing. In Comparative Examples 1 and 4, which did not use the silica for increasing, sufficient initial viscosity was not secured, and in Comparative Example 3 using an excess of silica for increasing compared to the present preparation example, the viscosity over time reached 100,000 cP after 1 month, and the pump was turned off. It became difficult to dispense toothpaste through the

Experimental Example 2. Discharge per container and remaining amount

The toothpaste composition prepared in Preparation Examples and Comparative Examples is filled in a pump-type toothpaste container (delamination container) according to Example 2 of the present invention and a dip pump toothpaste container including a structure in which a dip tube is connected to a conventional air pump, and the Texture Analyzer ( TA instrument) was discharged at a rate of once per minute, and the discharge properties were evaluated by discharging until it was no longer discharged, and the results are shown in Table 4 below.

Discharge was evaluated based on 30% of the total filling amount after discharging. When the residual amount exceeds 50%, it was evaluated that the measurement of the residual amount was not meaningful.

As shown in Tables 4 and 5, the toothpaste composition according to the present preparation example has excellent discharging properties in the delamination container according to Example 2 of the present invention at the initial and after 1 month, and exhibited a residual amount of 8% or less. . The toothpaste composition having a content ratio of sorbitol and polyol according to Preparation Examples 11 to 16 also had excellent discharge properties in the delamination container, and showed a residual amount of 6% or less.

In Comparative Example 2, abrasive silica was used instead of silica for thickening, and the viscosity results showed that discharge was possible, but the piston was abraded and the discharge stability was poor. In Comparative Example 3, the increase in viscosity over time was too large by using an excessive amount of silica for grading, so it was impossible to discharge with an airless pump.

Experimental Example 3. Reshaping after dispensing of toothpaste composition

The toothpaste composition prepared in Preparation Examples and Comparative Examples was filled in a pump-type toothpaste container according to Example 2 of the present invention and then pumped once and discharged in the form of a lump on a plastic plate marked with a scale.

After 5 seconds of discharging, the height of the mass was measured and expressed as a ratio (height/diameter) to the diameter of the outlet of the pump-type toothpaste container to evaluate the shape retention of the discharged toothpaste mass. If the shape retaining property is 0.70 or more, even if it is discharged to the toothbrush, the shape does not collapse or seep into the bristles, so a case of 0.70 or more can be evaluated as good.

Preparation Example 1 Preparation 2 Preparation 3 Preparation 4 Preparation 5 shape retention 0.80 0.82 0.83 0.90 0.85 Preparation 6 Preparation 7 Preparation 8 Preparation 9 Preparation 10 shape retention 0.92 0.88 0.90 0.90 0.95 Preparation 11 Preparation 12 Preparation 13 Preparation 14 Preparation 15 Preparation 16 shape retention 0.83 0.88 0.9 0.9 0.85 0.9 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 shape retention 0.45 0.62 1.00 0.68 0.89

It was found that the toothpaste composition of Preparation Example 3 and Comparative Example 3 containing silica for thickening had excellent shape retention properties. The toothpaste composition according to Comparative Examples 1, 2, and 4 exhibits shape retention properties such as flowing down when discharged to a toothbrush. Comparative Example 3 showed good shape retention, but the increase in viscosity was large, so it could not be completely discharged, and it was unsuitable for use in pump toothpaste because it exhibited a high discharge pressure of 4 kgf or more.

Experimental Example 4. Dispensing stability according to the drying of the discharge port after discharging the toothpaste composition

The toothpaste composition prepared in Preparation Examples and Comparative Examples was filled in the pump-type toothpaste container according to Example 2 of the present invention, and then pumped once and discharged. After leaving the toothpaste composition in the discharge port of the container for 1 month at room temperature, pumping again was performed to measure the discharge pressure, and the discharge stability was evaluated by checking whether the discharge port was clogged. (Discharge pressure evaluation ○: less than 4 kgf , ×: 4kgf or more or the outlet is blocked)

stability ○ ○ ○ ○ ○ ○ ×

With the composition according to Preparation Examples 11 to 16, the toothpaste composition using liquid and solid polyols or using only liquid polyols was discharged without blocking the discharge port of the container. In the toothpaste composition according to Comparative Example 5, it was visually observed that the container discharge port was blocked, and the discharge pressure was also 4 kgf or more, which was evaluated as having no discharge stability.
