PGMA Polymer Coating for Hard Surface Soil Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions for hard surfaces struggle to effectively remove mobile soils, particularly greasy soils, especially when they become adherent and tougher over time, requiring more effort to clean, and often leave residues that may be harmful to consumers.
Innovation Solution
Aqueous hard surface cleaning composition comprising a polyglycerol methacrylate (PGMA) polymer with a molecular weight of over 100,000 Daltons and a surfactant, such as anionic or nonionic surfactants, which provides a next-time cleaning benefit by easing the removal of soils across a wide pH spectrum without leaving harmful residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cleaning compositions are used to remove soils from hard surfaces, then cleaning ability is provided, but more effort is required to remove adherent and toughened soils over time
Solution Approach 1:
The cleaning composition applies a polymer coating to the hard surface beforehand, creating a protective layer that prevents soils from adhering and toughening. This preliminary action ensures that when soils are deposited later, they remain mobile and easy to remove, avoiding the need for intensive cleaning efforts on adherent soils.
Solution Approach 2:
The polymer acts as an intermediary substance between the hard surface and the soil. It forms a coating layer that modifies the interaction between the surface and soil, preventing direct adhesion and making soil removal easier without requiring strong mechanical or chemical cleaning actions.
2Reliability
If cleaning compositions are applied frequently to remove soils promptly, then soil removal effectiveness is maintained, but increased cleaning frequency consumes more time and resources
Solution Approach 1:
By applying the polymer coating in advance, the invention creates a long-lasting protective effect that maintains soil removal effectiveness over extended periods. This eliminates the need for frequent cleaning interventions, thereby improving productivity and reducing time and resource consumption.
Solution Approach 2:
The invention changes the surface properties of the hard surface by applying a polymer coating with specific characteristics (molecular weight, functional groups). This parameter change in the surface properties provides sustained anti-adherent effects, maintaining cleaning effectiveness without requiring frequent reapplication or intensive cleaning cycles.
3Power
If strong cleaning agents are used to remove toughened soils, then cleaning power is increased, but harmful residues may be left on the surface
Solution Approach 1:
The polymer coating is applied in advance to prevent soil from toughening and adhering to the surface. This preliminary protective action maintains soil mobility, allowing gentle cleaning methods to be used instead of strong cleaning agents, thereby avoiding the deposition of harmful residues on the hard surface.
Solution Approach 2:
Instead of using strong cleaning agents that may leave harmful residues, the invention converts the approach by using a benign polymer coating that prevents soil adhesion in the first place. The polymer itself serves as a beneficial substance that eliminates the need for harmful strong cleaners, turning the prevention strategy into a benefit.
