Powdered Toothpaste Pumice Coating Fluidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powdered leaf extracts for gum treatment are highly hydrophilic, leading to clumping and loss of usability due to their inability to maintain fluidity during storage when used in toothpaste form.
Innovation Solution
A fluid powder toothpaste is created by coating crushed pumice stone grains with dry papaya leaf extract particles, which maintains fluidity and enhances the synergistic effects of the papaya leaf properties through a specific production method involving decoction, filtration, and hot air atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If powdered leaf extract is used for gum treatment, then anti-inflammatory effect is improved, but fluidity is worsened due to clumping
Solution Approach 1:
The patent uses pumice stone grains as an intermediary carrier to support the hydrophilic leaf extract particles. The pumice grains prevent direct contact between extract particles, eliminating clumping while maintaining the extract's anti-inflammatory properties. This mediator approach resolves the contradiction between preserving therapeutic effect and maintaining fluidity.
Solution Approach 2:
The invention creates a composite material combining pumice stone grains with leaf extract particles. The composite structure leverages the hydrophobic characteristics of pumice to counterbalance the hydrophilic nature of the extract, preventing clumping while delivering the therapeutic benefits of the plant extract.
2Duration of action of stationary object
If powdered leaf extract is stored, then availability for use is improved, but fluidity is worsened due to clumping
Solution Approach 1:
The patent performs preliminary coating of the extract particles onto pumice grains before storage. This pre-treatment prevents clumping from occurring during storage by establishing a physical barrier in advance, ensuring the mixture remains fluid and usable throughout the storage period.
Solution Approach 2:
The pumice grains serve as a stable intermediary that maintains separation between extract particles during storage. This mediator prevents the hydrophilic extract particles from aggregating over time, preserving fluidity throughout the storage duration.
3Ease of operation
If extract particles are coated on pumice grains, then fluidity is improved, but manufacturing complexity is worsened
Solution Approach 1:
The patent employs fluidization technology using air flow to suspend and mix the pumice grains and extract particles uniformly. This pneumatic approach enables efficient coating and homogeneous distribution without requiring complex mechanical mixing equipment, thus improving fluidity while controlling manufacturing complexity.
Solution Approach 2:
The invention utilizes changes in physical parameters such as air flow rate and temperature during the coating process to achieve uniform distribution of extract particles on pumice grains. By optimizing these parameters, the process achieves good fluidity results with relatively simple equipment requirements.

AI summary
The powdered toothpaste comprises crushed pumice grains coated with particles of dry extract of fruit tree leaves, in particular papaya leaves, and is preferably obtained by implementing a process comprising the steps: - making a decoction of fruit tree leaves in water, - filtering the decoction using a sieve with a mesh size of 100 µm, - adding crushed pumice with grains having a maximum dimension of 100 µm, - and atomizing the mixture in a stream of hot air having an inlet temperature close to 300°C and an outlet temperature close to 100°C.
