Non-ionic Surfactant Oral Care Composition Pellicle Lubricity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral care compositions fail to effectively maintain and enhance the lubricity of the mouth by protecting the dental pellicle, leading to inadequate oral lubrication.
Innovation Solution
A non-ionic surfactant comprising polyethylene glycol ethers of fatty alcohols, such as Steareth 30, is used in combination with natural gums like carrageenan to deposit on the existing pellicle layer, enhancing its thickness and lubrication properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional oral care compositions are used, then teeth cleaning is achieved, but the dental pellicle is removed and oral lubrication is insufficient
Solution Approach 1:
The patent converts the harmful effect of surfactants that remove the dental pellicle into a beneficial effect by using non-ionic surfactants that specifically deposit on and enhance the pellicle layer. The surfactant composition is designed to differentiate between cleaning tooth surfaces while preserving and thickening the protective pellicle film, thereby transforming the potential harm of surfactant use into a protective benefit.
Solution Approach 2:
The patent changes the chemical parameters of the surfactant system by specifying non-ionic surfactants with particular hydrophilic-lipophilic balance (HLB) values and molecular structures. This parameter change allows the surfactant to interact differently with the dental pellicle compared to conventional anionic surfactants, resulting in pellicle enhancement rather than removal while maintaining cleaning effectiveness.
2Object-affected harmful factors
If the dental pellicle is maintained, then oral lubrication is improved, but cleaning effectiveness may be reduced
Solution Approach 1:
The patent applies local quality by creating different surfactant interactions at different locations in the oral cavity. The non-ionic surfactant composition is designed to have affinity for the dental pellicle at tooth surfaces, depositing and thickening it, while still providing cleaning action on the tooth enamel. This localized differentiation allows simultaneous pellicle maintenance and effective cleaning.
3Object-affected harmful factors
If non-ionic surfactants are used to enhance pellicle, then oral lubrication is improved, but composition complexity increases
Solution Approach 1:
The patent achieves universality by designing a non-ionic surfactant composition that performs multiple functions simultaneously: it cleans tooth surfaces, maintains and thickens the dental pellicle, and provides oral lubrication. This multi-functional approach eliminates the need for separate ingredients or complex formulations, as the single surfactant system accomplishes all three objectives through its specific molecular properties and interactions.
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 preserves and enhances the lubricity of the mouth by building up the pellicle layer, providing improved oral lubrication comparable to compositions without surfactants, while minimizing the presence of anionic surfactants and other additives.
Implementation Method 1
The present application relates to the non-therapeutic use of a non-ionic surfactant comprising polyethylene glycol ether of a fatty alcohol, in a composition to promote lubricity of the mouth
Implementation Method 2
The composition deposits on the existing pellicle layer and thus helps protect the pellicle
Implementation Method 3
The enhanced layer results in an increased lubrication which is, in the context of the present invention, seen as an enhancement
