Description

Anhydrous super sticky two-component teeth whitening film

technical field

The invention relates to a sticking film used for whitening human teeth, in particular to a sticking film capable of whitening human teeth, which belongs to the field of oral products.

Background technique

With the continuous improvement of people's living standards, modern people pay more and more attention to the love, care and beauty of teeth. The requirements for tooth beauty and whitening are increasing day by day, and the methods and effects of tooth beauty and whitening are getting higher and higher. It is required not only to not damage the dentin during the cosmetic whitening process of the teeth, but also to save time and convenience, to be simple and practical, and to have remarkable effects. The methods and products for teeth whitening are facing deeper issues.

Teeth whitening methods and products can be roughly divided into two types. One is the method of using mechanical or ultrasonic cleaning. The disadvantage of this type of method is that it only cleans the teeth and cannot decolorize and increase the stains on the teeth. The whitening effect has a certain damage to the dentin and needs to be operated by a professional in a hospital or a dentist's office, which takes time and is not convenient enough, and the generation of tooth stains is regular and persistent, and it is impossible to pass several times or A limited number of cleanings achieves the purpose of frequent whitening of teeth, and mechanical whitening teeth whitening will thin the enamel and cause damage to the dentin.

Another type is the method of bleaching with chemical substances, that is, bleaching the teeth with chemical bleaching agents. In medicine, this method is administered through dental braces, so that the bleaching agent can keep in contact with the tooth surface for a long time and release active ingredients. The commonly used bleaching agent is Opalescemce depigmentation agent, its active ingredient is 10% carbamide peroxide (Carbamide peroxide) or other high-concentration peroxides are used to bleach teeth, and high-concentration peroxides have strong acidity, which is harmful to teeth and Other surrounding tissues have a strong stimulating effect, the course of treatment is long and the price is relatively high, which is difficult for ordinary consumers to recognize and accept.

At present, the use of chemical methods to make dental film to whiten and whiten teeth is becoming more and more popular and widely used. The current tooth whitening film is roughly divided into two types: dry film and wet film. Most of these films are A large proportion and high concentration of peroxide is used as the main bleaching agent, and the proportion of peroxide is about 10%. However, peroxide is a very unstable substance, and the effect will change over time. It is getting worse and worse. At present, the solution to this problem is mainly to increase the content of peroxide and add peroxide stabilizers to adjust the stability of peroxide. Increasing the content of peroxide will affect the tooth and its surrounding tissues. It is very irritating to use, and the gel overflows during use, which will aggravate the irritation of the oral cavity, and there are problems such as weak sticking, easy to fall off, and uncomfortable use; in addition, after the peroxide is added with a stabilizer, it is stable over time. It is controlled to a certain extent, but it also reduces the effectiveness of peroxides, destroys the release state and role of peroxides in decomposing active oxygen, and affects the whitening effect to a large extent. Therefore, the current tooth whitening Sticking film, though have advantage and certain effect of simple to use, convenient and practical, also have described shortcoming and deficiency.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned shortcomings and deficiencies existing in the existing tooth whitening film, and provide a kind of anhydrous super sticky two-component tooth whitening film, which solves the problem of reducing tooth whitening due to the water content of the whitening component of general tooth whitening film. The technical problem of whitening effect and solves the technical problem of low adhesion force and short adhesion time of general teeth whitening film to tooth surface. The most important thing is to overcome the time-dependent stability of peroxide-containing whitening products, improve the whitening effect of teeth, and also prolong the storage time of products, and will not cause the whitening ingredients to decompose and lose due to prolonged storage.

The technical solution of the present invention is: it is composed of two components, including the anhydrous ultra-viscous whitening component of component A and the active penetration-promoting component of component B.

Component A is a two-layer structure, the first layer is a super sticky whitening layer, and the second layer is a release backing layer. The first layer of ultra-sticky whitening layer is made of peroxide as a tooth whitening agent and a polymer film-forming material capable of forming an ultra-mucosa. There are three preferred formulations for implementation, and its preferred formulation A1 is:

The second layer of component B is an active permeation-promoting layer that is close to the first layer. Its formula contains polymer film-forming materials that can form a super mucous membrane, which produces strong viscosity and can be whitened with the first layer of component A. The layers are fused together, so that the peroxide can release active oxygen, and the oxygen free radicals in the active oxygen can quickly penetrate into the enamel and neutralize the color base in the tooth, and promote the decomposition of the color base to achieve the tooth whitening effect. The formula of the second active penetration-promoting layer of component B corresponds to the formula of the first super-viscous whitening layer of component A. There are three optimal formulas available for implementation, which correspond to the super-viscous whitening layer of component A Preferred formulation B1 of preferred formulation A1 is:

Or replace the preferred formula B1 of component B’s active penetration-promoting layer with the preferred formula B2 corresponding to the preferred formula A2 of component A’s ultra-viscous whitening layer:

Or replace the preferred formula B1 of the second layer of component B with the preferred formula B3 corresponding to the preferred formula A3 of the super-viscous whitening layer of component A:

The preparation method of the second active permeation-promoting layer of component B is also to dissolve its formula in the volatile solution alcohol, and then dry the volatile solution alcohol at a temperature of 60°C to 80°C. It is between 0.01mm and 0.05mm, and its shape is suitable for the user's gums and teeth. Its formula can promote the release of peroxide in component A and make the whitening ingredients penetrate into the enamel to achieve whitening. Effect.

Component B The third release backing layer is attached to the second layer and is a transparent or opaque plastic film, preferably PET plastic film, foil or paper. Its surface in contact with the second layer is coated with release agent silicon or fluorine or their mixture, so that the second layer can be easily peeled off from the third layer.

When using, first peel off the first layer of super sticky whitening layer of component A from the second release backing layer, stick it on the teeth, and then put the first layer of water-proof adhesive layer of component B and the second layer The active penetration enhancing layer is peeled from the third release backing layer and attached to the first ultra-adhesive whitening layer of component A.

The present invention adopts a two-component operation mode, which can effectively prolong the activity of the peroxide. The whitening component of component A of the present invention is completely independent, and a ph neutralizing agent is added to make the ph value of the second layer appear as Alkaline, ph adjustment between 3-4, the stability of the peroxide in the whitening component will be greatly improved in such an environment, it will not decompose due to the prolongation of storage time, and the activity of component B The ph value of the penetration-promoting component is around 8-10. When used, it can neutralize the acidity in the whitening component of component A to 6-7, so that the product reduces acidic irritation to the mouth during use, and can Accelerate the decomposition of peroxide and release more free oxygen, so as to achieve the best tooth whitening effect.

Polymer materials used in the present invention include hydroxypropyl methylcellulose, PVP-K90, PVP-K30, and mixtures thereof.

PVP-K30 and PVP-K90 are polyvinylpyrrolidone products, which are non-ionic polymer copolymers with certain viscosity, but they are mixed with hypromellose and dissolved in volatile alcohol solution, and then dried at high temperature. After drying, it can reach ultra-high viscosity and can form a highly viscous film-like substance.

The peroxide is selected from one or more of the following substances: hydrogen peroxide, carbamide peroxide, sodium perborate or combinations thereof.

An advantage of the present invention is that component A is a completely water-free formula and a dry structure, which can better wrap the tooth whitening agent, and will not cause the whitening agent to decompose and become unstable due to the presence of water. The dry structure also makes the product more reliable over time.

Another advantage of the present invention is that the pH value of component A is acidic or weakly acidic, and the peroxide itself is acidic. Under such acidic conditions, the peroxide will be better protected so that it will not produce decomposition or a small amount of Decomposition, so that the storage time of the product is greatly extended, and the tooth whitening effect is further improved.

A more important advantage of the present invention is that component B adopts an alkaline structure, which can neutralize the pH value of component A during use, so that users will not have the acidity to bring stimulation to the teeth, and the environment is neutral. When the conditions of neutrality and alkalinity are close, the peroxide will quickly decompose. When component B is attached to component A, it can quickly neutralize the pH value of component A, thereby promoting the peroxide on component A. Accelerated release and penetration into the enamel, so as to achieve a more superior tooth whitening effect.

To sum up, the present invention adopts a brand-new two-component combination design, provides a more reliable product with longer active ingredient retention and more outstanding use effect, and brings a new comfortable and convenient oral care. idea.
