Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning compositions, such as those described in JP 2014-218465A, are unsatisfactory in terms of foamability, foam fineness, and foam stability, failing to produce fine and stable foams with resilient texture.
Innovation Solution
A cleaning composition comprising an anionic surfactant, methyl cellulose, and hydroxypropyl methyl cellulose, with a mass ratio of methyl cellulose to hydroxypropyl methyl cellulose in the range of 40:60 to 80:20, which enhances foamability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cleaning composition uses only modified alkyl hydroxyalkyl cellulose as a thickening agent, then the composition can be manufactured simply, but the foamability, foam fineness and foam stability remain unsatisfactory
Solution Approach 1:
The patent applies composite materials by combining methyl cellulose and hydroxypropyl methyl cellulose in a specific mass ratio (40:60 to 80:20) to create a cleaning composition that achieves both good foamability and foam stability. This composite approach allows the composition to overcome the limitations of using single cellulose derivatives alone, providing fine and stable foams with resilient texture while maintaining manufacturing simplicity.
2Device complexity
If the cleaning composition uses a single type of cellulose derivative, then the formulation is simple, but the foam fineness and foam texture quality are insufficient
Solution Approach 1:
The patent employs composite materials by formulating a mixture of methyl cellulose and hydroxypropyl methyl cellulose in a specific mass ratio range (40:60 to 80:20). This composite formulation achieves fine foam texture and improved foam fineness while keeping the overall formulation relatively simple, thus resolving the contradiction between formulation complexity and foam quality.
Solution Approach 2:
The patent applies local quality by optimizing the specific mass ratio of methyl cellulose to hydroxypropyl methyl cellulose (40:60 to 80:20) to achieve particular foam properties. This localized optimization of component ratios allows the composition to produce fine and stable foams with resilient texture, addressing the foam fineness requirement without excessive formulation complexity.
3Ease of manufacture
If conventional surfactant-cellulose combinations are used, then the composition is easy to manufacture, but the foamability and foam resilience are inadequate
Solution Approach 1:
The patent applies composite materials by combining methyl cellulose and hydroxypropyl methyl cellulose in a specific mass ratio (40:60 to 80:20) to enhance foamability and produce fine, stable foams with resilient texture, while maintaining ease of manufacture through a relatively simple formulation approach.
