Hydrogen Peroxide Whitening Gel With Controlled Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrogen peroxide dental whitening gels suffer from immediate release of hydrogen peroxide in liquid form due to the oxidation of thickeners by mouth temperature, leading to gingival irritation and ineffective whitening, and existing solutions like gingival barriers do not fully address this issue.
Innovation Solution
A hydrogen peroxide dental whitening gel comprising colloidal silicon dioxide, potassium and aluminum silicate, and crystalline aluminum dioxide, which stabilizes and disperses hydrogen peroxide, preventing immediate release and enhancing whitening efficacy by retaining reactive oxygen species for prolonged oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen peroxide gel is used for teeth whitening, then whitening effect is achieved, but hydrogen peroxide is immediately released in liquid form causing gingival irritation
Solution Approach 1:
The patent introduces colloidal silicon dioxide as an intermediary substance that absorbs and retains hydrogen peroxide in the gel matrix. This mediator prevents the immediate release of liquid hydrogen peroxide while maintaining its whitening efficacy through prolonged contact with teeth, thereby eliminating gingival irritation without sacrificing whitening performance
Solution Approach 2:
The patent changes the physical state and distribution parameters of hydrogen peroxide by incorporating it into a gel matrix with specific colloidal particles. This transforms the immediate liquid release into a controlled, prolonged release mechanism, altering the temporal and spatial parameters of peroxide delivery to achieve both safety and efficacy
2Reliability
If hydrogen peroxide gel is used for teeth whitening, then whitening effect is achieved, but thickeners are oxidized by mouth temperature causing immediate peroxide release
Solution Approach 1:
Colloidal silicon dioxide serves as a stable intermediary framework that prevents direct oxidation of thickeners by mouth temperature. The gel matrix structure stabilized by these colloidal particles maintains hydrogen peroxide retention even at physiological temperatures, preventing decomposition and immediate release while preserving whitening effectiveness
Solution Approach 2:
The patent creates a composite gel system combining hydrogen peroxide, colloidal silicon dioxide, and thickeners. This composite structure leverages the stabilizing properties of colloidal particles to protect thickeners from thermal oxidation, maintaining gel integrity and peroxide stability at mouth temperature without compromising whitening performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gel effectively prevents gingival irritation while achieving superior whitening results by maintaining reactive oxygen species, ensuring safer and more efficient tooth whitening compared to prior art.
Implementation Method 1
The colloidal silicon dioxide absorbs and retains water
Implementation Method 2
Peroxides of different compositions gradually decompose, releasing molecular oxygen and active forms of oxygen
Implementation Method 3
This is caused by the oxidation of thickeners (carbopolymers, glycerol and propylene glycol) contained in the gel
Implementation Method 4
crystalline aluminum dioxide

AI summary
Disclosed is a dental whitening gel with a hydrogen peroxide aqueous solution, a colloidal silicon dioxide in amorphous form, a potassium and aluminum silicate, and an aluminum dioxide in crystalline form. With the addition of the hydrogen peroxide aqueous solution, the crystalline molecules contained in the mixture of solid components produce a gel, wherein the hydrogen peroxide aqueous solution is attracted by the crystalline molecules so as to surround said crystalline molecules, forming an atmosphere that surrounds the crystalline molecules
