Microemulsion Cleaning Composition with Adipate Solvent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microemulsion systems for cleaning surfaces, particularly those with high oil and grease content, lack effective degreasing and drainage capabilities, resulting in inefficient cleaning and residue issues.
Innovation Solution
A cleaning composition comprising an aqueous component, an organic solvent, an anionic surfactant, an amine co-surfactant with either an N-oxide or zwitterionic group, and a nonionic surfactant, formulated as a microemulsion or microemulsion preconcentrate, which efficiently removes grease and allows for fast drainage with minimal residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional microemulsion systems are used for cleaning surfaces with high oil and grease content, then the cleaning composition can maintain stability and homogeneity, but the degreasing capability and drainage performance are insufficient
Solution Approach 1:
The patent applies composite materials by combining multiple surfactants (anionic, nonionic, and amine oxide types) with specific organic solvents (dipropyl adipate or diisopropyl adipate) to create a microemulsion system that achieves superior degreasing capability while maintaining stability. This composite approach allows the system to handle high oil and grease content effectively, resolving the contradiction between reliability and productivity in cleaning performance.
2Stability of the object's composition
If conventional microemulsion systems are used, then the composition can be stable and homogeneous, but drainage capability is poor resulting in residue issues
Solution Approach 1:
The patent applies parameter changes by carefully controlling the HLB values of surfactants (anionic surfactant with HLB 10-16, nonionic surfactant with HLB 8-14, and amine oxide surfactant with HLB 12-18) and adjusting the concentration of organic solvent (0.1-10%) to optimize both microemulsion stability and drainage capability. This parameter optimization allows the system to drain quickly from surfaces without leaving residue, resolving the contradiction between stability and ease of operation.
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 provides efficient degreasing and drainage capabilities, ensuring effective cleaning of hard surfaces with minimal residue, maintaining homogeneity and clarity, and is suitable for kitchen and bathroom surfaces.
Implementation Method 1
Microemulsions are stable liquid dispersions of water and oil, together with one or more surfactants and co-surfactants
Implementation Method 2
Because of their thermodynamic stability and their ability to take up relatively high volumes of oily substances, e.g., in the internal phase of the particles in an oil-in-water microemulsion
