Embodiment 1

[0031]A series of 1 molar aqueous solutions containing 23% sodium fluoride were prepared using acids with different pKa values, and the pH was adjusted to 4 with sodium hydroxide. After the solubility of these solutions was determined, one bovine tooth (with polished surface) was soaked in these solutions for 24 hours respectively, and the photo of the bovine tooth had been taken in advance. The soaked bovine teeth were removed from the solution and photographed. Compare the color of your teeth before and after soaking. The comparison method is carried out in the following way: A group of 20 experts are invited to observe the photos of the cow teeth before and after treatment, and evaluate them. If the cow teeth are whitened after treatment, it is indicated by ○; if there is no change, it is indicated by × . In the course of the evaluation, if the bovine teeth were considered to have become white but lost their luster, they were also marked with X. Compositions rated as ○ b...

The oral composition contains the following components (A), (B) and (C): (A) 0.02-0.7wt.% (based on fluorine atom) fluoride; (B) 0.1-5mol / kg , an acidic compound or its salt with a pKa value (25° C.) of 2.5 to 6.0; (C) 5 to 90 wt.% of water, and the pH value of the composition itself or its 30 wt.% aqueous solution is in the range of 3 to 5.5 between.

Description

technical field [0001] The invention relates to a composition for oral cavity which has whitening effect when acting on the surface of teeth, more specifically relates to a composition for oral cavity which can whiten teeth and increase the luster of tooth surface. technical background [0002] The external cause of tooth discoloration is that colored substances adhere to the tooth surface, such as tartar, plaque, smoke stains, or daily coffee or tea; the internal cause is tooth discoloration caused by aging, and this discoloration is expressed through highly transparent enamel, or in Enamel-forming age Medications such as tetracycline can cause discoloration of the enamel itself. In order to fundamentally whiten teeth, it is necessary to take measures against not only external factors but also internal factors. [0003] So far, various physical or chemical methods have been reported for teeth whitening. Among the known physical methods, in addition to the method of removi...
