Description

A toothpaste composition with improved loosening properties

The present invention relates to a toothpaste composition comprising a structurant and a thickener, and more particularly, to a toothpaste composition having improved shape retention, loosening properties, freshness, scent dissipation power, cleaning power, and stain removal power.

In the case of toothpaste, loosening properties at the time of use are important for rapid delivery of active ingredients. This excellent loosening property has a great influence on the rapid delivery of the active ingredient contained in the toothpaste, foam formation, and consumer feeling.

In addition, in the conventional conventional toothpaste, xanthan gum or the like is mixed to make the thickening system so that the toothpaste is discharged from a container such as a tube. That is, a thickener or binder is contained in order to form the viscosity of the toothpaste. A conventional toothpaste composition contains a thickening agent or a binder in a high concentration.

However, when the thickening power is strong, a bonding force is created between the components of the toothpaste as a whole due to the thickening agent, which causes a problem that the toothpaste that is agglomerated by saliva or brushing does not come off well. In the case of the composition, it has the disadvantage of easily flowing down due to its low viscosity, so it is widely used as an oral gargle that suppresses oral bacteria and removes bad breath. It was not possible to exhibit the effect of sufficient brushing such as toothpaste (Korean Patent Application No. 2001-7004081).

Accordingly, the present inventors have studied to solve the problems of the prior art. As a result, when a structurant is used instead of reducing the content of the thickener, it has a certain viscosity and a phase angle so that the shape retention property is maintained while loosening property when used. Found this improved toothpaste composition, and confirmed that it has excellent cleaning power and stain removal power, thereby completing the present invention.

Korean Patent Application No. 2001-7004081

One object of the present invention is to provide a toothpaste composition comprising a structurant and a thickener.

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

On the other hand, each description and embodiment disclosed herein may also be applied to each other description and embodiment. That is, all combinations of the various elements disclosed herein are within the scope of the present invention. In addition, it cannot be said that the scope of the present invention is limited by the specific descriptions described below.

In addition, those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the invention described herein. Also, such equivalents are intended to be encompassed by the present invention.

As one aspect of the present invention for solving the above problems, the present invention provides a toothpaste composition comprising a structurant (structurant) and a thickener.

The term "structurant" used in the present invention agglomerates toothpaste components by a polymer network due to strong interaction between polymers itself, and has high gelation ability, but has relatively low interaction with other toothpaste components including water, so that saliva , means that the structure is easily collapsed by external forces such as soaking in toothpaste or brushing before use, and thus the loosening properties are strengthened. In order to compensate for the disadvantages of using the thickener, it may be included in place of the thickener to improve loosening properties and maintain shape retention.

The structuring agent in the present invention may be one or more components selected from the group consisting of carrageenan and carbomer, but is not limited thereto.

The term "phase angle" used in the present invention refers to an angle corresponding to the tangent value by using 'viscosity/elasticity' as a trigonometric tangent value. Specifically, it is as follows.

In the dynamic oscillatory shear test, the vibration frequency is ω, the phase delay between stress and strain is δ, and G' is the modulus of elasticity without energy loss because there is no phase difference between strain and stress. represents the component and is a measure of the stored energy, and G" represents the viscosity of the material and is a measure of the energy lost as heat. Here, the ratio of G" to G', G"/G', is the loss tangent (loss tangent, tan δ), which means the ratio of viscosity to elasticity of a material (energy loss/energy stored), and is referred to as the phase angle (FIG. 1).

Solids have low loosening properties, and liquids have strong loosening properties. From the concept of phase angle, ideal solids are perfectly elastic, and deformation is stored as energy. In other words, compared to elasticity (the ability to return to the original state when an external force is applied), the viscosity (the extent to which the contents flow when an external force is applied) is very low, and the phase angle approaches 0, conversely, the ideal liquid is a perfectly viscous material, where deformation is lost without being stored as energy. That is, as the elasticity is very low compared to the viscosity, the phase angle approaches 90 degrees (FIG. 2).

The phase angle value of the toothpaste composition in the present invention may be 20 to 90, specifically 25 to 70, or 30 to 50, may be 30 to 40, more specifically 20 to It may be 50, 20 to 40, or 20 to 30, but is not limited thereto. At this time, the toothpaste of the present invention is in a state that is relatively close to a liquid state compared to a conventional toothpaste, and due to this state, has a very excellent release property. However, if it is too close to the liquid state, it is difficult to discharge a desired constant amount of toothpaste to the toothbrush, and since the shape retention on the toothbrush becomes a problem, it is preferable to have a phase angle of a certain level.

As used in the present invention, the term "low viscosity" is a shear viscosity measured at a low speed, which means how hard the state of the liquid in the solid is. Specifically, when an external force is applied, how much the state is It means tolerating well. Low shear viscosity in the present invention was defined as the viscosity at a shear rate of 0.1 s ^-1 . The toothpaste composition in the present invention exhibited a state close to a liquid state compared to a conventional toothpaste.

The toothpaste composition in the present invention may have a viscosity of 50,000 to 110,000 cP after storage at 20 to 30° C. for 7 days, specifically, 50,000 to 100,000 cP, but is not limited thereto.

In the case of a conventional conventional toothpaste composition, it is confirmed that the toothpaste composition having a final viscosity of 40,000 cP or less, more specifically 20,000 cP or less, has very good loosening properties, whereas in a toothpaste composition having a viscosity of 50,000 cP or more, the loosening property of the toothpaste is very poor. On the other hand, in the case of a toothpaste composition having a viscosity of 50,000 cP or more, it was confirmed that it was suitable for tube formulation as a paste formulation. In this case, the viscosity was measured using a No. 7 spindle bar at a rotation speed of 20 rpm using a viscometer (Brookfield RVF).

On the contrary, in the toothpaste composition of the present invention, it was confirmed that the loosening property was very excellent even when the viscosity was 50,000 cP or more.

The thickener of the present invention serves as a binder included in the toothpaste composition and mouthwash, and functions to prevent the solid powder component from being separated from the liquid component. In addition to the function of preventing the separation of toothpaste components, it affects the appearance of toothpaste such as shape retention and transparency, extrudability from the toothpaste tube, and the use properties such as loosening properties during brushing. affect. Any kind of water-soluble polymer may be used, and may be composed of an organic thickener and an inorganic thickener.

In particular, the "organic thickener" in the present invention may specifically mean that the interaction with water has a relatively higher property compared to the interaction between the organic thickeners, and due to this property, the synergistic power of the toothpaste composition is increased. can increase

The content ratio of the structuring agent and the organic thickener in the present invention may be 0.2: 1 to 6: 1, specifically, 0.3: 1 to 5: 1, and more specifically, 0.5: 1 to 4: 1. may be, but is not limited thereto.

The organic thickener in the present invention may specifically be one or more components selected from the group consisting of poloxamer, polysaccharide, and CMC (carboxymethyl cellulose), and more specifically, the group consisting of floxamer and polysaccharide It may be one or more components selected from, but is not limited thereto. The polysaccharide may be one or more components selected from the group consisting of xanthan gum, gellan gum, and locust bean gum, but is not limited thereto. In addition, carboxymethyl cellulose (CMC), which is a kind of organic thickener, is known to have side effects such as gastrointestinal disorders, constipation, and diarrhea when ingested excessively. cellulose) may not be included, but is not limited thereto.

In particular, CMC has a characteristic that hydration and dispersion do not occur well under conditions of low water content. It is characterized in that it contains a relatively high content.

The organic thickener in an embodiment of the present invention may be 0.0001 to 2%, specifically 0.0001 to 1%, and more specifically 0.0001 to 0.6%, based on the total content of the toothpaste composition, It is not limited.

The inorganic thickener in the present invention may be one or more components selected from the group consisting of thickening silica, colloidal silica, and fumed silica, but is not limited thereto. The inorganic thickener is a component that does not significantly affect loosening properties, and exhibits sufficient viscosity even in a state where the water content is small.

The inorganic thickener in one embodiment of the present invention may be 1 to 30%, specifically 1.5 to 20%, and more specifically 2 to 10%, based on the total content of the toothpaste composition, but It is not limited.

The toothpaste composition in the present invention may further include water having a content of 15% or less, specifically 1% to 15%, based on the total weight of the composition, and more specifically 1% to 10% or 1% to 8% may be, but is not limited thereto.

Instead of containing water in a non-aqueous or small content, a liquid polyol such as glycerin, PEG, PG, etc. may be included as a dispersion solvent of toothpaste components, but is not limited thereto. Specifically, the liquid polyol interacts with a thickener As long as it does not cause a substantial increase in viscosity of the composition, it may be included as a dispersion solvent of the toothpaste composition according to the present invention. In this case, the content of the liquid polyol may be 20 to 80% based on the total weight of the composition, but is not limited thereto.

In particular, the liquid polyol may include glycerin, and in this case, the content of glycerin may be 30 to 70%, specifically 40 to 70%, more specifically 50 to 70%, based on the total weight of the composition. , but is not limited thereto.

In general, when the amount of water in the toothpaste composition is high, the viscosity increases due to the thickener and the binding of the toothpaste base component may be strong, thereby weakening the loosening properties.

Accordingly, in the present invention, in order to maintain shape retention even in a state in which the content of water is reduced, the content of the organic thickener is reduced, and a structuring agent and an inorganic thickener are included to provide excellent shape retention and loosening properties.

According to one embodiment of the present invention, it was confirmed that the toothpaste composition of the present invention has an improved effect of shape retention and loosening properties.

As used in the present invention, the term "retaining property" refers to a property of discharging toothpaste onto the bristles and maintaining the original shape of the toothpaste without flowing down on the toothbrush when used.

However, when the thickening power is increased to improve shape retention, a bonding force is created between the components of the toothpaste as a whole due to the thickening agent, which may cause a problem in that the toothpaste that is clumped by saliva or brushing is not easily released.

Accordingly, the toothpaste composition of the present invention is characterized in that it improves shape retention and at the same time has excellent loosening properties.

The term "dispensability" used in the present invention refers to the dispensability of dispensing the toothpaste that is agglomerated when it is wetted, such as by saliva or water, after being discharged from the contents container containing the toothpaste to the toothbrush. This excellent loosening property has a great influence on the rapid delivery of the active ingredient contained in the toothpaste, foam formation, and consumer feeling.

The faster the toothpaste is dispersed in water, the faster it is also dispersed in the mouth, and this rapid dispensability is an important factor in increasing the contact time of the toothpaste with the tooth surface. In the present invention, it was confirmed that the fast dispersing power is mainly related to the gel-structure and thixotropy, and it was found that the silica for thickening with a high oil absorption value had a great effect on the dispersing power. However, it was not easy to have an excellent rheology while giving a viscosity of 50,000 or more with the silica for increasing use alone. Accordingly, when the water content in the toothpaste is lowered and the concentration of the thickener is low, it was confirmed that the toothpaste composition with a viscosity that can be used by putting it in a tube in a paste formulation has excellent loosening properties, and the feeling of use due to the rapid release of the fragrance and active ingredient And it was confirmed that the cleaning effect was also excellent.

According to an embodiment of the present invention, it was confirmed that the toothpaste composition of the present invention has an improved effect of freshness and fragrance dissipation.

It was confirmed that the toothpaste composition in the present invention has excellent loosening properties, and also has excellent flavor dissipation power, and the freshness is improved.

The toothpaste composition in the present invention may further include one or more components selected from the group consisting of abrasives, surfactants, wetting agents, medicinal agents, additives and foaming agents, but is not limited thereto.

As used herein, the term "abrasive" refers to a material that serves to polish the surface of teeth to wipe off plaque.

In the present invention, the abrasive is one selected from the group consisting of dental type silica, precipitated silica, silica gel, calcium monohydrogen phosphate, calcium carbonate, hydrous alumina, insoluble sodium metaphosphate, calcium pyrophosphate, zirconium silicate and hydroxyapatite. may be more than

The term "surfactant" used in the present invention improves the compatibility and cleaning action of the oral composition, and facilitates the dispersion and penetration of the active ingredient to easily remove foreign substances from the oral cavity.
