Oral Composition Stabilization for Hydrocarbon Oil Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compositions with a relatively lower water content and a relatively larger hydrocarbon oil content have poor stability over time, leading to separation of hydrocarbon oil during long-term storage, making them unsuitable for oral applications.
Innovation Solution
An oral composition comprising hydrocarbon oil, polyhydric alcohol, and surfactant, specifically combinations of glycerol with polyglycerol fatty acid ester and alkyl glucoside, propanediol with polyoxyethylene hardened castor oil fatty acid ester, butylene glycol with polyoxyethylene alkyl ether, or polyethylene glycol with polyoxyethylene hardened castor oil fatty acid ester, maintains stability by controlling the water content at 5 mass% or less and adjusting the mass ratio of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mouthwashes containing alcohol and surfactants are used, then antiseptic effect is achieved, but mucous membrane irritation and dry mouth occur
Solution Approach 1:
The patent removes harmful components (alcohol, surfactants, strong menthol) from the mouthwash formulation while retaining the antiseptic function through alternative ingredients like plant extracts and mild essential oils, directly resolving the contradiction between efficacy and irritation
Solution Approach 2:
The patent converts potentially harmful substances into beneficial ones by replacing alcohol with plant-based extracts and surfactants with natural compounds, transforming the formulation from irritating to soothing while maintaining antiseptic properties
2Reliability
If strong antiseptic ingredients are used, then bacterial killing effect is improved, but taste becomes unpleasant and user compliance decreases
Solution Approach 1:
The patent changes the chemical parameters of the formulation by using plant extracts and essential oils with pleasant aromas instead of strong chemical antiseptics, achieving both bacterial killing and acceptable taste to improve user compliance
Solution Approach 2:
The patent creates a composite formulation combining multiple plant extracts and essential oils that work synergistically to provide antiseptic action while maintaining pleasant sensory properties, resolving the contradiction between efficacy and acceptability
3Productivity
If frequent use of conventional mouthwashes is performed, then oral hygiene is maintained, but mucous membrane damage accumulates
Solution Approach 1:
The patent formulates the mouthwash with soothing plant extracts that actively repair and protect the mucous membrane while cleaning, allowing frequent use without cumulative damage by making the product self-healing for the tissue
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 achieves excellent stability over time, suitable for use in toothbrushes and interdental brushes, ensuring the hydrocarbon oil remains stable and evenly distributed without separation.
Implementation Method 1
contains thymol in an amount of 0.01 wt % to 0.05 wt % based on the total weight of the composition, said composition having a pH of 6.0 to 8.0, thereby providing an effective antiseptic action
Implementation Method 2
said composition having a pH of 6.0 to 8.0
