Embodiment 2

[0305] The membrane of Example 2 increased the total polyphosphate content to 10% of the membrane volume, with 5% being cyclic polyphosphate and 5% being linear polyphosphate. This resulted in an improved increase in brightness compared to the film of Comparative Example 1, in which no polyphosphate was present, and the film of Comparative Example 2, which contained linear polyphosphate in an amount of 7%. Thus, reducing the concentration of linear polyphosphate to an amount below 7% in the presence of cyclic polyphosphate results in an increase in brightness.

[0306] The membrane of Example 1 had a reduced total polyphosphate content of 7% compared to the 10% total phosphoric acid in Example 2, which resulted in both cyclic polyphosphate and linear polyphosphate at 3.5% of the membrane. The amount exists, so the content of total polyphosphate 7% is equivalent to embodiment 3. Compared with 3.07 of Example 2 and 2.23 of Comparative Example 1, the change in brightness of Exam...

Abstract

The invention provides a tooth whitening film. The tooth whitening film comprises a tooth bleaching agent, one or more polyphosphates, one or more water-soluble film-forming polymers, one or more plasticizers, and one or more emulsifiers, where the tooth bleaching agent comprises hydrogen peroxide in a non-hydrogen peroxide bleaching agent and / or a hydrogen peroxide-polymer complex, the one or more polyphosphates include one or more cyclic polyphosphates, and the film has a thickness of from about 50 [mu] m to about 500 [mu] m. Also provided is a kit comprising one or more such films and orthodontics having a thickness of from 50 [mu] m to about 150 [mu] m. Also provided is a process for preparing the film, and a method for bleaching teeth using the film.

Description

technical field [0001] The present invention relates to tooth whitening films. It also relates to a preparation process of the tooth whitening film and a method for bleaching teeth using the tooth whitening film. Background technique [0002] Human teeth naturally take on a variety of colors, which can be influenced by many factors, such as diet and medications. For example, some foods, such as berries, and beverages, such as tea and red wine, contain chromogens that can stain teeth. Tobacco also darkens teeth. Other substances, such as acidic fruits and beverages, can promote staining by eroding tooth enamel, softening teeth and making it easier for pigments to attach to teeth. Therefore, it is desirable to remove these stains by whitening the teeth. [0003] Peroxides are a class of compounds containing oxygen-oxygen single bonds, which have a bleaching effect on organic matter. Typically, these compounds release hydrogen peroxide, which acts as an active bleach, when...
