Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard surface cleaning compositions often leave streaks and residues on polished surfaces, particularly when dealing with greasy soils, and fail to effectively remove common stains like hard water, soap scum, and rust stains in kitchen and bathroom environments.
Innovation Solution
A low-streaking hard surface cleaning composition comprising 0.01-1.5% amine oxide surfactants, 0.5-6% C1-C3 monohydric alcohol, 0.05-0.85% phenyl-containing glycol ether solvent, 0-5% non-phenyl glycol ether solvent, 0.1-5% alkanolamine, and up to 0.005% silicone-based antifoaming agent, with at least 90% water, excluding cationic and anionic surfactants, and using isopropanol and propylene glycol phenyl ether as organic solvents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hard surface cleaning compositions are used to remove greasy soils and stains, then cleaning effectiveness is improved, but streaking and residue formation on polished surfaces worsen
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by using amine oxide surfactants with specific alkyl chain lengths (C12-C16) and combining them with phenyl-containing glycol ethers. This parameter change allows effective grease removal while minimizing streaking and residue on polished surfaces.
Solution Approach 2:
The invention creates a composite cleaning system by combining amine oxide surfactants with phenyl-containing glycol ethers and C1-C3 monohydric alcohols. This composite formulation achieves synergistic effects that simultaneously provide strong cleaning power and low streaking characteristics.
2Reliability
If strong surfactants are used to effectively remove greasy soils, then cleaning power is improved, but residue formation on surfaces worsens
Solution Approach 1:
The patent modifies the surfactant parameters by selecting amine oxides with specific alkyl chain lengths (C12-C16) and combining them with phenyl-containing glycol ethers. This parameter optimization maintains strong cleaning power while reducing residue formation through improved rinsability.
3Reliability
If the cleaning composition is made more concentrated to improve cleaning effectiveness, then stain removal capability is improved, but viscosity increases making the composition less pumpable and pourable
Solution Approach 1:
The patent optimizes the concentration parameters of active ingredients within specific ranges (0.01-1.5% amine oxide, 0.5-6% C1-C3 monohydric alcohol, 0.05-0.85% phenyl-containing glycol ether) to achieve effective stain removal while maintaining low viscosity for good pumpability and pourability.
Solution Approach 2:
The invention uses different components with specific functions at different concentration levels - amine oxides for cleaning, phenyl-containing glycol ethers for low streaking, and C1-C3 monohydric alcohols for viscosity control - allowing each component to operate at its optimal concentration for the desired local effect.
