Oral Composition Gloss via Phytic and Pyrophosphoric Acid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional whitening agents fail to effectively remove minute solid matter and impart gloss to teeth in a short time, as they do not adequately address the adhesion of calcium phosphates and organic substances on tooth surfaces.
Innovation Solution
An oral composition combining phytic acid and pyrophosphoric acid, with a specific pH range of 5.5 to 6.5 and a mass ratio of 0.2 to 3.0, that does not contain polyvalent cations or fluoride, to rapidly remove minute solid matter and enhance gloss imparting effects on teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional whitening agents are used, then teeth can be whitened to some extent, but minute solid matter adhering to tooth surface cannot be sufficiently removed and gloss cannot be effectively imparted
Solution Approach 1:
The patent changes the chemical parameters by using phytic acid with controlled pH (5.5 to 6.5 when diluted to 30% by mass) and specific concentration (0.01 to 3% by mass), combined with pyrophosphoric acid or salts, to achieve effective removal of minute solid matter while imparting gloss to teeth
Solution Approach 2:
The patent combines phytic acid (or salt) with pyrophosphoric acid (or salt) in a composite oral composition, where the synergistic interaction between these two components enhances both the removal of minute solid matter and the gloss imparting effect on teeth
2Manufacturing precision
If phytic acid is used to remove minute solid matter, then gloss can be imparted to teeth, but polyvalent cations may interfere with the effectiveness
Solution Approach 1:
The patent extracts or removes polyvalent cations from the oral composition to prevent them from interfering with the effectiveness of phytic acid, thereby maintaining the stability and gloss imparting capability of the composition
Solution Approach 2:
The patent introduces pyrophosphoric acid (or salt) as an intermediary component that works synergistically with phytic acid to enhance the removal of minute solid matter and improve gloss imparting while maintaining compositional stability
3Manufacturing precision
If high concentration of phytic acid is used to enhance whitening effect, then more minute solid matter can be removed, but the composition may become less stable and less safe for oral use
Solution Approach 1:
The patent optimizes the concentration parameter of phytic acid to a specific range (0.01 to 3% by mass) and controls pH (5.5 to 6.5 when diluted to 30% by mass) to achieve effective whitening while maintaining composition stability and safety for oral use
Solution Approach 2:
The patent applies phytic acid at different concentrations in different contexts - sufficient concentration to effectively remove minute solid matter and impart gloss, but controlled within safe limits for oral use, achieving local optimization of both effectiveness and safety
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 a rapid and effective gloss imparting effect on teeth by selectively removing nano-scale solid matter without damaging the tooth surface, providing a natural luster and whitening action.
Implementation Method 1
minute solid matter which adheres to a tooth surface can be removed by using a composition which contains phytic acid and no polyvalent cation and having pH adjusted to a certain range
