Low Residue Cleaning Solution for Glossy Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions with cationic biocides leave significant residue on glossy surfaces, leading to filming and streaking issues when used with wet cleaning substrates, which reduces consumer acceptability and necessitates a follow-up wiping step.
Innovation Solution
A liquid cleaning composition containing a quaternary biocide absorbed onto a nonwoven substrate, which provides surface disinfection with low foaming and low residue, thereby minimizing filming and streaking, and eliminating the need for a follow-up wiping step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning composition containing cationic biocide is used with a wet cleaning substrate, then surface disinfection is achieved, but significant residue and filming are left on glossy surfaces
Solution Approach 1:
The patent modifies the chemical composition parameters of the cleaning solution by incorporating specific surfactants (nonionic and amphoteric), solvents (alcohols, glycol ethers), and chelating agents to control the drying behavior and residue formation. This chemical parameter optimization allows the cationic biocide to maintain disinfection efficacy while minimizing harmful residue on glossy surfaces.
Solution Approach 2:
The patent introduces intermediary substances including nonionic surfactants, amphoteric surfactants, and chelating agents that mediate between the cationic biocide and the surface. These intermediaries facilitate the disinfection process while preventing direct adhesion of the biocide to glossy surfaces, thereby reducing filming and residue.
2Object-generated harmful factors
If a spray cleaner is used, then residue problems are reduced, but an additional wiping step with a dry paper towel is required
Solution Approach 1:
The patent formulates the cleaning composition to self-level and self-dry without requiring manual intervention. The optimized surfactant and solvent system enables the cleaning solution to automatically distribute evenly and dry uniformly, eliminating the need for consumers to perform additional wiping steps with dry paper towels.
Solution Approach 2:
The patent adjusts the physical and chemical parameters of the cleaning composition, including surface tension, viscosity, and evaporation rate, to enable automatic drying behavior. These parameter optimizations allow the solution to dry cleanly on its own, removing the need for manual wiping while maintaining low residue.
3Area of stationary object
If a saturated wipe is used, then cleaning coverage is improved, but substantial liquid is left on the surface causing filming
Solution Approach 1:
The patent optimizes the liquid-to-solid ratio and the evaporation characteristics of the cleaning composition. By adjusting solvent types, concentrations, and surfactant levels, the formulation maintains adequate coverage during application while controlling the drying rate to prevent liquid pooling and filming on the surface.
Solution Approach 2:
The patent ensures continuous useful action by maintaining the cleaning solution in a state that promotes even distribution and controlled evaporation. The formulation allows the cleaning action to continue effectively as the liquid evaporates, preventing premature drying that would cause filming while maintaining coverage.
