Opaque Toothpaste Compositions Using Jammed Oil-in-Water Emulsions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Toothpaste compositions often require opacifiers like titanium dioxide to achieve opacity, which can lead to formulation instability and consumer preference for simpler compositions without additional ingredients.
Innovation Solution
A jammed oil-in-water emulsion toothpaste composition is developed, comprising an aqueous phase, hydrophobic phase, and emulsifier, which provides opacity without the need for opacifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If opacifiers like titanium dioxide are added to achieve opacity, then the toothpaste composition becomes opaque, but the formulation stability deteriorates and the composition complexity increases
Solution Approach 1:
The patent removes opacifiers (titanium dioxide) from the toothpaste formulation entirely, extracting the problematic ingredient that caused formulation instability while maintaining the desired opaque appearance through an alternative mechanism (oil-in-water emulsion system)
Solution Approach 2:
The patent changes the physical state and composition parameters by using an oil-in-water emulsion system with specific oil phases (coconut oil, palm oil, etc.) and emulsifiers to achieve opacity without solid opacifier particles, fundamentally altering how opacity is achieved in the formulation
2Illumination intensity
If opacifiers like titanium dioxide are added to achieve opacity, then the toothpaste composition becomes opaque, but the number of ingredients increases
Solution Approach 1:
The patent extracts and removes the opacifier ingredient (titanium dioxide) from the formulation, reducing the total number of ingredients while maintaining the opaque appearance through the emulsion system itself
3Illumination intensity
If additional ingredients are added to achieve opacity, then the toothpaste composition becomes opaque, but the formulation stability deteriorates due to ingredient interactions
Solution Approach 1:
The patent removes the problematic additional ingredient (opacifier) that caused instability through ingredient interactions, simplifying the formulation to core components (aqueous phase, hydrophobic phase, emulsifier) that work together without conflict
Solution Approach 2:
The patent uses a composite oil-in-water emulsion system where multiple oil phases (coconut oil, palm oil, etc.) and emulsifiers work together as an integrated system to provide both opacity and formulation stability without the need for separate opacifier additives
