Problems solved by technology

[0012] However, hydrogen peroxide is highly reactive with water, so it easily decomposes in water and has poor compatibility with other ingredients of toothpaste (such as polymers, abrasives, fluorine, foaming agents, etc.)
In particular, toothpastes containing hydrogen peroxide cannot be put into abrasives at the same time, so there is a disadvantage that the synergistic effect of these two mechanisms cannot be produced in terms of whitening effect
In this regard, toothpaste containing water as a solvent and containing a large amount of hydrogen peroxide, which is suitable for tube toothpaste, contains high viscosity, fluorine, foaming agents, abrasives, incense, etc., there is a decrease in the stability of peroxides over time, and occurrence The phase separation phenomenon of hydrogen peroxide makes it difficult to commercialize

preparation example Construction

[0090] Preservatives are used to prevent microbial contamination that may occur during the preparation and use of the oral composition and to help the long-term preservation of the toothpaste, and sodium benzoate or parabens and the like can be used.

[0091] As another aspect of the present invention, the present invention provides a toothpaste composition as a toothpaste composition comprising a phosphate-containing chelating agent and silicon dioxide, wherein the chelating agent is supersaturated to precipitate phosphate, and the phosphate is precipitated The content of the phosphate is more than 2%, specifically 2 to 10%, based on the total weight of the toothpaste composition.

[0092] The "precipitated phosphate" in the present invention refers to the phosphate added to the composition based on the maximum solubility of the solvent, especially water, based on 25°C. When the solvent is water, the water content can be obtained by known in the art. Water content measurement...

Embodiment 1 to 4 and comparative example 1 to 4

[0140] The toothpaste compositions of Examples 1 to 4 and Comparative Examples 1 to 4 were made from the ingredients and composition ratios shown in Table 1 below.

[0141] Specifically, after pre-dispersing structuring agents (carrageenan, carbomer) and thickeners (poloxamer, xanthan gum) in humectants (PEG, glycerin, etc.) (sodium fluoride, saccharin, etc.) those dissolved or dispersed in purified water, hydrated while stirring. Silica (silica for grinding, silica for thickening) was dispersed and mixed therein, followed by stirring for 20 minutes. Afterwards, a foaming agent (SLS, etc.) was added and stirred under vacuum for 20 minutes. The incense was added, followed by vacuum stirring for 20 minutes to make a toothpaste composition. However, the toothpaste composition of the invention of the present application is not limited to the above-mentioned preparation method.

[0144] Experimental example 1. Measuring the physical properties of toothpaste

[0145] (1) Viscosity measurement method

[0146] Viscosity was measured at 25°C with a viscometer (Brookfield RVF) at 20 rpm with a No. 7 Spindle bar.

[0147] (2) Tube suitability measurement method

[0148] The ability of the toothpaste composition to be poured into a typical toothpaste tube was evaluated.

[0149] (3) Solubility measurement method

[0150] 1) Consumer evaluation measurement method for solubility

[0151]It is a method in which the slurry is made by oneself, stirred for a certain period of time, and the degree of solubility is directly evaluated by the consumer. 12 adults were used as objects, and after brushing their teeth with 1 cm of the toothpaste of Examples 1 to 4 and Comparative Examples 1 to 4, Recorded on a 5-point scale: 5 points for very excellent solubility, 4 points for excellent solubility, 3 points for general, 2 points for slightly insufficient solubility, an...

Abstract

The present invention relates to a toothpaste composition comprising a structurant and a thickening agent, and particularly to a toothpaste composition which has a certain viscosity and phase angle by using a structurant and accordingly reducing the amount of a thickening agent, thus maintaining the shape retention of toothpaste, improving releasability when in use, and improving refreshment, fragrance release capacity, cleaning power, and stain removal power. Also, the present invention relates to a toothpaste composition with an enhanced whitening effect and sense of use, and particularly to a toothpaste composition comprising a phosphate-containing chelating agent and silica, wherein the chelating agent is supersaturated so that the phosphate is precipitated, and due to particles of the precipitated phosphate, strong cleaning power, a whitening effect, stain removal, and crunchiness are realized. Also, the present invention relates to a toothpaste composition comprising peroxide, a thickening agent, and a spreading agent, wherein, in particular, the peroxide and the thickening agent are in a form separated from each other, and particularly to a toothpaste composition having excellent sense of use, stability and whitening effect even in an anhydrous state.

Description

technical field [0001] The present invention relates to a toothpaste composition comprising a structurant and a thickener, in particular, to a toothpaste composition having improved shape retention, solubility in use, comfort, fragrance release, cleaning and A toothpaste composition with stain removal power. [0002] In addition, the present invention relates to a toothpaste composition having improved whitening effect and sense of use, and more particularly, to a toothpaste composition as a toothpaste composition comprising a phosphate-containing chelating agent and silicon dioxide , wherein the above-mentioned chelating agent is supersaturated to precipitate phosphate, and the particles of the precipitated phosphate achieve strong cleaning power, whitening effect, stain removal and rustling use feeling. [0003] In addition, the present invention relates to a toothpaste composition comprising a peroxide, a thickener and a spreading agent, especially the above-mentioned pero...
