Embodiment 1

[0029] A novel tooth whitening strip, comprising a backing layer, a gel layer and a film layer laminated in sequence, the gel layer is composed of the following components in percentage by weight: sodium carboxymethylcellulose 9%, sodium polyacrylate 2% %, glycerin 25%, polyethylene glycol 10%, deionized water 20%, hydrogen peroxide 12%, arginine 5%, stabilizer 0.01%, sucralose 0.01%, mint flavor 0.3%, bromelain 0.5% and absolute ethanol make up 100%; the stabilizer is a compound of acetic acid and hydroxyethylidene diphosphonic acid, wherein the weight ratio of acetic acid and hydroxyethylidene diphosphonic acid is 2:1.

[0030] The preparation method of the novel tooth whitening strip is as follows:

[0031] (1) Mix sodium carboxymethyl cellulose, sodium polyacrylate, glycerin, and polyethylene glycol evenly, heat to 130°C until completely dissolved to obtain liquid A, cool to 60°C, and set aside.

[0032] (2) Dissolve galactose and peppermint essence in absolute ethanol to...

Embodiment 2

[0036] This embodiment provides an anti-sensitivity tooth whitening strip, which is mainly composed of the following components in mass percentage: sodium carboxymethylcellulose 5%, carbomer 20%, glycerin 30%, deionized water 25%, peroxide Hydrogen 6%, Sodium Monofluorophosphate 5%, Stabilizer 0.01%, Trichlorogalactose 0.01%, Peppermint Flavor 0.3%, Papain 1%, Absolute ethanol make up 100%; The stabilizer is acetic acid and hydroxyethylidene A compound of diphosphonic acid, wherein the weight ratio of acetic acid to hydroxyethylidene diphosphonic acid is 2:1.

[0037] The preparation method of the novel tooth whitening strip is as follows:

[0038] (1) Mix sodium carboxymethyl cellulose, sodium polyacrylate, glycerin, and polyethylene glycol evenly, heat to 130°C until completely dissolved to obtain liquid A, cool to 60°C, and set aside.

[0039] (2) Dissolve galactose and peppermint essence in absolute ethanol to obtain liquid B, add liquid B to liquid A, stir evenly, wait u...

Abstract

The invention relates to a novel tooth whitening strip which comprises a backing layer, a gel layer and a thin film layer which are sequentially attached, and the gel layer is prepared from, by weight, 1%-15% of a thickening agent, 0.5%-5% of a gel, 20%-80% of a humectant, 0.1%-20% of an anti-allergic agent, 0.01%-0.5% of a sweetening agent, 0.01%-0.5% of essence, 0.001%-0.1% of a stabilizer, 20%-50% of deionized water and 1%-15% of hydrogen peroxide. And 0.5-1% of protease. The hydrogen peroxide type whitening tooth paste is stable in chemical component, low in hydrogen peroxide content and capable of reducing the tooth sensitivity risk of a user, and the whitening effect is more outstanding.

Description

technical field [0001] The invention belongs to the technical field of tooth whitening, and in particular relates to a novel tooth whitening strip. Background technique [0002] People's pursuit of white teeth makes the status of tooth whitening technology in oral clinical diagnosis and treatment increasingly rising. Teeth whitening is any process of whitening the color of teeth. Whitening can be done by physically removing stains or by chemically lightening the color of the teeth. [0003] At present, the most widely used bleaching agents are hydrogen peroxide (hydrogen peroxide, HP) and carbamide peroxide, CP). Studies have shown that 35% hydrogen peroxide is more effective than 15% hydrogen peroxide, but higher concentrations put patients at greater risk of tooth sensitivity. Additionally, hydrogen peroxide can oxidize other ingredients in the product formulation, reducing overall stability. [0004] Therefore, how to develop a tooth whitening strip with higher stabili...
