Problems solved by technology

The active ingredients of tooth whitening strips are usually hydrogen peroxide or carbamide peroxide, which are compressed with thickeners and stabilizers. During use, peroxides are corrosive, so whether it is dry tooth strips Or wet tooth paste will cause discomfort to the gums of some people. In addition, peroxide has a bleaching effect. Although the pigment on the surface of the tooth is bleached after use, the enamel presents an unnatural color, which is not the color of normal teeth. porcelain white
[0004] In addition, the dental stickers produced with the above-mentioned materials have great defects in the process of packaging and use. After the packaging bag is squeezed, the dental stickers are easy to deform or stick to the inside of the packaging bag and are inconvenient to take out. The teeth are easily deformed after being applied, and it is very easy to break when removed after use. The gel is easy to remain in the gaps between the teeth, which is inconvenient to clean. The customer experience of the dental strips in this way is not good, and the whitening effect is also affected because the gel cannot be evenly distributed. effect, and the production process and transportation process are prone to quality problems

preparation example Construction

[0031] Specifically, the preparation method of a flexible film for whitening teeth comprises the following steps:

[0032] S1: Mix and emulsify the above-mentioned oral composition for whitening teeth into a gel in a vacuum environment, so as to quickly form a gel and reduce air bubbles;

[0033] S2: Let the emulsified gel stand at a high temperature of 40-60°C for 24 hours, and at a low temperature of -8°C-10°C for 24 hours, and conduct a cold and heat alternating test and stability test. It is found through the test that the present invention provides The stability of the gel formed by the oral composition is significantly improved, and the qualified gel enters step S3 for processing;

[0034] S3: Lay the qualified gel on the upper and lower sides of the mesh fiber, and press the mesh fiber and gel evenly to form a sticker through the coating equipment, so that the mesh fiber is located in a quarter to two of the sticker. One part, preferably, the thickness of the sticker i...

Embodiment 1

[0043] In this embodiment, the oral composition for whitening teeth comprises the following ingredients:

[0044] Active ingredients: 3% sodium bicarbonate and 5% potassium nitrate;

[0045] Common ingredients: 15% water, 62.4% glycerin, 0.1% menthol, 6% cellulose carboxypropyl methyl ether, 5% PVP-K30, 3% PVP-K90, 0.5% ethylene glycol Disodium amine tetraacetate.

[0046] The flexible film patch that adopts above-mentioned oral composition to make, its preparation method is:

[0047] S1: mixing and emulsifying the above-mentioned oral composition for whitening teeth into a gel under a vacuum environment;

[0048] S2: Let the emulsified gel stand at a high temperature of 55°C for 24 hours, and at a low temperature of 2°C for 24 hours, conduct alternating cold and heat tests and stability testing, and the gels that pass the test enter step S3 for processing;

[0049] S3: Lay the qualified gel on the upper and lower sides of the mesh fiber, and press the mesh fiber and gel ev...

Embodiment 2

[0056] In this embodiment, the oral composition for whitening teeth comprises the following ingredients:

[0057] Active ingredients: 1% sodium bicarbonate and 3% potassium nitrate;

Abstract

The invention provides an oral composition for whitening teeth. The oral composition comprises common components and effective components, wherein the effective components comprise sodium bicarbonateand a potassium salt; the potassium salt comprises one or more of potassium nitrate, potassium oxalate, potassium citrate, potassium chloride and potassium phosphate. According to the oral compositionprovided by the invention, sodium bicarbonate with a whitening effect and the potassium salt with an anti-allergy effect are adopted, so that the discomfort to gingiva can be effectively reduced. Besides, the invention also provides a flexible film patch for whitening the teeth; the flexible film patch is more stable, easy to integrally remove after use and convenient to clean by adopting a modeof integrating the oral composition and the reticular fiber layer into a whole.

Description

technical field [0001] The invention relates to the field of oral care, in particular to an oral composition and a flexible film for whitening teeth. Background technique [0002] At present, with the improvement of people's living standards, people pay more and more attention to the beauty of their own teeth. There are many products for tooth beauty, including teeth whitening pens, teeth whitening trays, teeth whitening kits, whitening teeth strips, etc. Convenient, easy to use and affordable are favored by consumers. [0003] The structure of the dental strips currently produced in the market is formed by adding active ingredients into shaped gel tablets, and can be divided into dry dental strips and wet dental strips in terms of morphology. The glue produces stickiness, strong adhesion to teeth, and good whitening effect; wet dental strips already have stickiness, but poor adhesion to teeth and easy to fall off. The active ingredients of tooth whitening strips are usual...
