Dishwashing Composition for Soft Water Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual dishwashing methods with soft water fail to provide effective cleaning and long-lasting suds, as traditional compositions do not perform optimally in low water hardness conditions.
Innovation Solution
A detergent composition comprising anionic surfactants, a mixture of low and mid-cut amine oxide surfactants, and amphiphilic alkoxylated polyalkyleneimine is used, which includes a specific ratio of these components to create a robust cleaning system that maintains long-lasting suds in soft water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dishwashing compositions are used with soft water, then the composition is simple and easy to use, but cleaning performance and suds longevity are insufficient
Solution Approach 1:
The patent applies composite materials by formulating a dishwashing composition with a specific blend of multiple surfactant types (anionic surfactants, amine oxide surfactants, and amphiphilic alkoxylated polyalkyleneimine) rather than using a single surfactant. This composite surfactant system synergistically improves cleaning performance and suds longevity in soft water conditions while managing the complexity through defined concentration ranges for each component.
Solution Approach 2:
The patent applies parameter changes by optimizing the concentration ranges of different surfactant components in the composition. Specifically, it defines anionic surfactant content at 1-60% (preferably 5-50%), amine oxide surfactant at 3-15% (preferably 5-12%), and amphiphilic alkoxylated polyalkyleneimine at 0.1-2% (preferably 0.5-1.5%). These parameter optimizations ensure effective cleaning performance in soft water while controlling formulation complexity.
2Duration of action of stationary object
If traditional compositions are used in soft water, then the formulation is straightforward, but suds longevity is poor
Solution Approach 1:
The patent uses composite materials by combining multiple surfactant classes with complementary properties: anionic surfactants for primary cleaning, amine oxide surfactants for suds stabilization, and amphiphilic alkoxylated polyalkyleneimine as a co-surfactant. This composite approach extends suds longevity in soft water by creating a synergistic system where each component contributes to overall suds stability.
Solution Approach 2:
The patent extends suds longevity by optimizing the concentration parameters of surfactant components, particularly maintaining amine oxide surfactant at 3-15% and amphiphilic alkoxylated polyalkyleneimine at 0.1-2%. These parameter adjustments ensure sufficient suds stability in soft water conditions without requiring overly complex formulations.
3Reliability
If a robust surfactant system is designed for soft water performance, then cleaning effectiveness improves, but the composition becomes more complex
Solution Approach 1:
The patent applies composite materials by designing a multi-component surfactant system where anionic surfactants (1-60%), amine oxide surfactants (3-15%), and amphiphilic alkoxylated polyalkyleneimine (0.1-2%) work synergistically. This composite structure enhances surfactant performance in soft water by combining the cleaning power of anionic surfactants with the suds-stabilizing properties of amine oxides and the co-surfactant effects of the polyalkyleneimine.
Solution Approach 2:
The patent optimizes surfactant performance by carefully controlling the concentration parameters of each component. The defined ranges (anionic: 1-60%, amine oxide: 3-15%, polyalkyleneimine: 0.1-2%) ensure robust cleaning effectiveness in soft water while managing composition complexity through standardized formulation guidelines.
