Calcium Silicate Oral Care Composition for Benefit Agent Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral care compositions face challenges in delivering benefit agents effectively to tooth surfaces due to poor adhesion, leading to rinsing off during daily hygiene routines, which hampers their whitening and remineralization efficacy.
Innovation Solution
An oral care composition comprising calcium silicate, a soluble calcium source, and a phosphate source, in a specific weight ratio, enhances the deposition and binding affinity of benefit agents to tooth surfaces, improving delivery efficiency and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If benefit agents are incorporated in oral care compositions to provide whitening and remineralization benefits, then the effectiveness of such benefit agents can be improved, but the benefit agents do not strongly adhere to tooth surfaces and are easily rinsed off during daily oral hygiene routine
Solution Approach 1:
The patent uses calcium silicate particles as intermediary carriers that mediate between the benefit agents and tooth surfaces. These particles provide a physical platform that holds benefit agents and facilitates their transfer to teeth, solving the adhesion problem without requiring direct bonding between benefit agents and tooth surfaces.
Solution Approach 2:
The patent changes the physical parameters of the benefit agent delivery system by incorporating particles with specific size ranges (0.1-10 micrometers). This parameter change enables the benefit agents to be carried on particle surfaces, improving both delivery efficiency and retention during rinsing.
2Reliability
If calcium silicate is used in combination with soluble calcium sources and phosphate sources, then the deposition of benefit agents on tooth surfaces can be enhanced, but the composition complexity increases
Solution Approach 1:
The patent merges multiple functional components into a single oral care composition: calcium silicate particles serve as carriers, soluble calcium sources provide remineralization, phosphate sources enhance deposition, and benefit agents deliver active effects. This combination creates synergistic effects that improve overall performance while maintaining formulation simplicity.
Solution Approach 2:
The calcium silicate particles perform multiple functions simultaneously: they act as carriers for benefit agents, provide structural support for deposition, and work synergistically with calcium and phosphate sources to enhance overall tooth benefits. This multi-functionality reduces the need for separate components.

Function Achieved in This Case
The composition effectively deposits and retains benefit agents on tooth surfaces, enhancing whitening and remineralization, and providing improved oral hygiene benefits by forming a new calcium phosphate layer that resists shear forces.
Implementation Method 1
the deposition of benefit agents on tooth surfaces can be enhanced by using calcium silicate in combination with soluble calcium sources and a phosphate source
