Effervescent Xylitol Powder Composition for Rapid Saliva Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral hygiene compositions comprising an effervescent couple and xylitol suffer from poor dissolution in saliva, leading to undesirable mouth feel and reduced efficacy in plaque control and tooth decay prevention.
Innovation Solution
A powder oral hygiene composition with a water surface area greater than 160 m²/g, comprising 80 wt% to 95 wt% of xylitol, 3 wt% to 9 wt% of a carbon dioxide source, 1 wt% to 5 wt% of an adsorbent, and 1 wt% to 5 wt% of an acid, which dissolves quickly and smoothly in the mouth, enhancing plaque control and tooth decay prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing effervescent dentifrice compositions are used, then plaque control and tooth decay prevention functions are provided, but dissolution in saliva is poor leading to undesirable mouth feel and reduced efficacy
Solution Approach 1:
The patent changes the physical parameter of water surface area to greater than 160 m²/g through specific particle size distribution control. This parameter change enables rapid dissolution in saliva while maintaining the effervescent reaction components (sodium bicarbonate 3-9 wt%, citric acid 1-5 wt%) for plaque control and tooth decay prevention functionality.
Solution Approach 2:
The patent segments the particle size distribution into specific ranges: 80-95% of particles pass through 45 µm mesh, 5-15% pass through 75 µm mesh, and 0-5% pass through 106 µm mesh. This segmentation creates the required water surface area for rapid dissolution while preserving the effervescent couple's plaque control efficacy.
2Object-generated harmful factors
If effervescent dentifrice powder is placed in the oral cavity, then the composition effervesces and cleanses the mouth, but the dissolution rate is slow and mouth feel is undesirable
Solution Approach 1:
The patent applies parameter changes by controlling the water surface area to be greater than 160 m²/g through specific particle size distribution. This transforms the dissolution rate from slow to rapid, and improves mouth feel from undesirable to smooth and pleasant, while maintaining the effervescent cleaning function.
Solution Approach 2:
The patent creates a dynamic particle size distribution that optimizes dissolution kinetics. The majority of fine particles (80-95% through 45 µm) provide rapid wetting and dissolution, creating a smooth mouth feel, while the effervescent reaction proceeds effectively for plaque control.
3Adaptability or versatility
If conventional effervescent compositions are used, then basic oral hygiene function is provided, but consumer acceptance is reduced due to poor dissolution and mouth feel
Solution Approach 1:
The patent changes the water surface area parameter to greater than 160 m²/g through controlled particle size distribution. This improvement in dissolution characteristics and mouth feel directly enhances consumer acceptance and adaptability of the effervescent dentifrice composition.
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 provides improved dissolution and mouth feel, increasing consumer acceptance and efficacy in plaque control and tooth decay prevention, with enhanced bactericidal activity against Streptococcus mutans.
Implementation Method 1
the solubilized bicarbonate and acid in the resulting saliva mixture undergo a rapid acid-base reaction generating carbon dioxide gas in an effervescent reaction
Implementation Method 2
generating carbon dioxide gas in an effervescent reaction. The resulting salivary solution or paste is swept through the oral cavity
Implementation Method 3
plaque is adsorbed over time by the silica particles (adsorbents)
Implementation Method 4
the saliva wets the composition, dissolving the bicarbonate, and the solubilized bicarbonate and acid in the resulting saliva mixture
