Oral Retention Composition Using Shellac-Coated Functional Substances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Functional substances in oral compositions are easily washed away by saliva and exudates, and retention-enhancing substances often interact with functional substances, reducing their effectiveness, especially when acidic polysaccharides are used with basic or polyphenolic substances.
Innovation Solution
An oral retention composition comprising shellac or zein-coated functional substances mixed with acidic polysaccharides, such as carrageenan, hyaluronic acid, or xanthan gum, to enhance retention time in the oral cavity without significantly impairing the retention-imparting function of the acidic polysaccharides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If retention-enhancing substances are added to improve functional substance retention in the oral cavity, then retention time is extended, but the functional substances interact with retention-enhancing substances, greatly reducing or eliminating their effects
Solution Approach 1:
The invention divides the functional substance into coated particles, where each particle is individually coated with a protective layer. This segmentation prevents interaction between the functional substance and acidic polysaccharides while maintaining retention enhancement, thereby preserving both retention time and effectiveness
Solution Approach 2:
The invention introduces an intermediary coating layer (such as shellac, zein, or other protective coatings) between the functional substance and acidic polysaccharides. This intermediary prevents direct interaction that would otherwise reduce effectiveness, while still allowing the acidic polysaccharides to provide retention enhancement
2Duration of action of moving object
If acidic polysaccharides are used as retention-enhancing substances, then viscosity is increased to improve retention, but when functional substances are basic substances or polyphenols, the retention-enhancing action is greatly reduced
Solution Approach 1:
By coating basic substances and polyphenols as separate particles before mixing with acidic polysaccharides, the invention prevents direct chemical interaction that would reduce viscosity. Each coated particle maintains its integrity while the acidic polysaccharides provide retention enhancement through viscosity increase
Solution Approach 2:
The coating layer acts as an intermediary barrier that prevents direct interaction between basic substances/polyphenols and acidic polysaccharides. This allows the acidic polysaccharides to maintain their viscosity-imparting properties while still providing retention enhancement for the functional substances
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 effectively prolongs the retention of functional substances in the oral cavity, suppressing the decrease in viscosity of acidic polysaccharides and maintaining their antimicrobial and biofilm inhibition activities, thereby extending the duration of their effects.
Implementation Method 1
the functional substance coated with the at least one compound selected from the group consisting of shellac and zein
Implementation Method 2
the retention-enhancing action (e.g., viscosity-imparting) of the acidic polysaccharide
Implementation Method 3
the decrease in the viscosity of the acidic polysaccharide caused by the functional substance can be suppressed
