  • Patent number: 12491144
    Abstract: A toothpaste composition has silica and a precipitated phosphate. The content of the precipitated phosphate is 2% to 10%, based on the total weight of the toothpaste composition and the average diameter of the precipitated phosphate particles is 75 ?m to 180 ?m. The toothpaste composition of the present invention was confirmed to have the effects of improving the cleaning power and the stain removal power. The toothpaste composition has excellent effect of removing stains on the tooth surface and brightening teeth.
    Type: Grant

  • Patent number: 11701313
    Abstract: A toothpaste composition includes a structurant and a thickener, wherein the toothpaste composition has a predetermined viscosity and phase angle by using the structurant instead of reducing the content of a thickener, and thereby has an improved release property during use while maintaining a shape retention property of the toothpaste, and has an improved feeling of refreshment, flavor releasing power, cleaning power, and stain removal power. Further, provided is a toothpaste composition including a chelating agent containing phosphate and silica, wherein the chelating agent is supersaturated to precipitate phosphate to provide strong cleaning power, a whitening effect, a stain removal effect, and a crunchy sensation. Further, provided is a toothpaste composition including a peroxide, a thickener, and a spreading agent, wherein the peroxide and the thickener are separated from each other, providing excellent sense of use, stability, and a whitening effect in an anhydrous state.

  • Publication number: 20150150366
    Abstract: The present invention provides a toothbrush bristle comprising: a core area including a rubber elastic body; and a clad area which is formed around the circumference of the core area, and which includes a resin that is harder than the rubber elastic body, wherein a tip from which the core area is exposed is formed in an end portion thereof. Thus, since the tip is formed in the end portion which comes in contact with the gum such that the rubber elastic body is exposed therefrom, the invention provides the advantage of softly massaging the gums while brushing the teeth.
