Cleaning Composition for Long-Lasting Water Repellency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions for hard surfaces often leave residues, streaks, or films, especially on shiny surfaces, and fail to provide long-lasting water-repellency and protection against soil, lime scale, and buildup, requiring frequent reapplication and thorough rinsing.
Innovation Solution
A cleaning composition comprising a polymer system with a hydrophobic organoalkoxysilane, a hydrophilic polymer, a surfactant system, and an organic acid, which forms a long-lasting hydrophobic film on surfaces when dried, enhancing water-repellency and shine while preventing soil and lime scale buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If detergent builder salts or non-phosphate builder salts are used in liquid cleaning compositions, then phosphate levels in ground water are reduced, but films, spots, or streaks are left on cleaned shiny surfaces
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by using specific surfactant systems (anionic, nonionic, and/or zwitterionic surfactants) in controlled concentrations (0.1% to 5% by weight) instead of traditional detergent builder salts. This parameter change allows the composition to clean surfaces effectively without leaving residual films, spots, or streaks, while also being environmentally friendly by reducing phosphate levels in groundwater.
Solution Approach 2:
The patent employs a composite surfactant system comprising multiple types of surfactants (anionic, nonionic, and/or zwitterionic) working synergistically. This composite approach provides superior cleaning performance on shiny surfaces without leaving residues, while maintaining environmental compatibility by eliminating phosphate builders.
2Productivity
If conventional cleaning compositions are used to clean hard surfaces, then cleaning activity is provided, but water-repellency is not long-lasting and frequent reapplication is required
Solution Approach 1:
The patent applies a preliminary protective action by incorporating hydrophobic polymers and silane-based compounds into the cleaning composition. These ingredients deposit a thin hydrophobic film on the cleaned surface during the cleaning process itself, providing long-lasting water-repellency that prevents soil, lime scale, and buildup for extended periods, eliminating the need for frequent reapplication.
Solution Approach 2:
The cleaning composition performs multiple functions simultaneously: it cleans the surface through surfactant action, protects against water through hydrophobic polymer deposition, and prevents soil and mineral buildup through the silane-based protective film. This multi-functional approach combines cleaning activity with long-lasting protection in a single application.
3Manufacturing precision
If thorough rinsing is performed to remove films and spots from cleaned surfaces, then surface cleanliness is improved, but time consumption increases
Solution Approach 1:
The cleaning composition is formulated to be self-rinsing by using surfactant systems that do not leave residual films, spots, or streaks on cleaned surfaces. The composition cleans effectively and rinses away completely with water, requiring no manual wiping or extended rinsing time. The hydrophobic polymers and silane compounds deposit as invisible protective films that do not interfere with surface appearance or require additional removal steps.
