Peroxide Booster System for Teeth Whitening Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tooth whitening compositions are inadequate in providing superior whitening benefits and stability, as they often rely on peroxide as the primary whitening agent, which may not effectively address deep-seated stains and can be unstable during storage and use.
Innovation Solution
A tooth whitening composition comprising a polyvinylpyrrolidone-hydrogen peroxide complex combined with a bleach activator, such as sodium nonanoyloxybenzenesulfonate, along with an abrasive and anticalculus agent, stored separately to enhance stability and whitening efficacy, forming a stable anhydrous or low-water vehicle for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If peroxide is used as the primary whitening agent, then whitening action is provided, but stability during storage and use deteriorates
Solution Approach 1:
The patent divides the whitening system into separate components: peroxide complex and bleach activator. These components are stored separately and only mixed at the time of use, preventing premature decomposition of peroxide while maintaining storage stability and ensuring whitening efficacy when activated.
Solution Approach 2:
The patent introduces a bleach activator as an intermediary substance that enhances the whitening action of peroxide. The activator reacts with peroxide to form more effective whitening agents, thereby improving productivity without compromising the stability of the stored components.
2Productivity
If conventional peroxide formulations are used, then whitening action is achieved, but superior whitening benefit for deep-seated stains is not provided
Solution Approach 1:
The patent employs composite material strategies by combining peroxide with a polyvinylpyrrolidone complex and incorporating a bleach activator. This composite formulation enhances penetration into deep-seated stains and improves overall whitening benefit while managing composition complexity through systematic formulation.
Solution Approach 2:
The patent modifies the chemical parameters of the whitening system by complexing peroxide with polyvinylpyrrolidone and introducing a bleach activator. These parameter changes enhance the ability to reach and treat deep-seated stains, improving productivity without excessive complexity.
3Ease of operation
If peroxide and bleach activator are stored together, then convenience is improved, but stability deteriorates
Solution Approach 1:
The patent segments the formulation into separate peroxide complex and bleach activator components that are stored independently. This segmentation maintains stability during storage while allowing convenient combination at the time of use through a simple mixing process or single-application system.
Solution Approach 2:
The patent prepares both components (peroxide complex and bleach activator) in advance in their respective stable forms, then combines them at the appropriate time. This preliminary preparation ensures stability during storage while enabling convenient activation and use.
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 composition achieves enhanced whitening by stabilizing the peroxide and bleach activator, allowing for prolonged and effective stain removal, with the bleach activator increasing the whitening effect and maintaining stability over time, even in aqueous environments like the oral cavity.
