Ultraphosphoric Acid Salt Oral Stain Remover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oral compositions and tooth cleaning materials fail to completely remove stains and plaque from teeth, especially in areas difficult to reach with a toothbrush, and struggle to prevent re-deposition of stains and plaque on teeth surfaces.
Innovation Solution
An oral stain remover containing a salt of ultraphosphoric acid with an average degree of polymerization of 7 to 12, used in an oral composition with a pH of 4 to 8 and a concentration of 0.5 to 10% by weight, which effectively removes stains and plaque without brushing and prevents re-deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional oral compositions containing salts of polyphosphoric acid or metaphosphoric acid are used, then some stain removal effect is achieved, but stain and plaque cannot be completely removed from teeth surfaces
Solution Approach 1:
The patent changes the chemical parameter by using ultraphosphoric acid instead of conventional polyphosphoric acid or metaphosphoric acid. This parameter change results in superior stain removal capability, completely removing stain and plaque from tooth surfaces including difficult-to-reach areas, whereas conventional compositions only achieve partial removal
Solution Approach 2:
The patent creates a composite oral composition by combining ultraphosphoric acid with specific additives including salts of polyphosphoric acid or metaphosphoric acid, surfactants, and flavoring agents. This composite formulation synergistically enhances the stain removal effect beyond what single components can achieve
2Productivity
If conventional oral compositions are used for daily brushing, then some plaque is removed, but stain and plaque build up in difficult-to-reach areas
Solution Approach 1:
The patent replaces the mechanical action of toothbrushing with a chemical solution based on ultraphosphoric acid. This substitution allows the stain remover to effectively clean difficult-to-reach areas without requiring physical brushing pressure, thereby improving both efficiency and accessibility
3Manufacturing precision
If conventional oral compositions are used, then some cleaning effect is achieved, but stain and plaque re-deposit on teeth surfaces
Solution Approach 1:
The ultraphosphoric acid-based composition prevents stain and plaque re-deposition by creating a protective effect on the tooth surface. This preliminary protective action maintains clean tooth surfaces over extended periods, preventing the buildup that occurs with conventional compositions
