Aqueous acidic hard surface cleaning liquid composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard surface cleaning compositions face challenges in achieving both good anti-bacterial performance and shine performance without negatively affecting the treated surface, as high levels of citric acid and alkyl polyglucoside surfactant can lead to stickiness and shine loss.
Innovation Solution
The combination of citric acid and formic acid with alkyl polyglucoside surfactant in an aqueous acidic composition, balanced at a pH of 1.9 to 3.5, allows for effective anti-bacterial performance and shine retention without using quaternary ammonium compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high levels of citric acid are used, then anti-bacterial performance is improved, but the treated surface becomes sticky and shine performance deteriorates
Solution Approach 1:
The acid system is segmented into two distinct components: citric acid (0.15-4.00 wt%) for anti-bacterial activity and formic acid (0.05-1.00 wt%) for shine enhancement. This segmentation allows each acid to perform its specialized function without the negative effects of excessive concentrations of a single acid component.
Solution Approach 2:
The invention changes the concentration parameters of both acids to optimal ranges rather than using high levels of citric acid alone. By adjusting citric acid to 0.15-4.00 wt% and adding formic acid at 0.05-1.00 wt%, the system achieves both anti-bacterial performance and shine retention without stickiness.
2Productivity
If high levels of alkyl polyglucoside surfactant are used, then cleaning performance is improved, but shine performance deteriorates
Solution Approach 1:
The surfactant concentration is optimized to a moderate range (0.10-2.5 wt%) rather than using high levels. This parameter adjustment maintains effective cleaning performance while preventing the shine deterioration that occurs with excessive surfactant concentrations.
3Reliability
If quaternary ammonium compounds are used for anti-bacterial performance, then anti-bacterial performance is improved, but environmental friendliness deteriorates
Solution Approach 1:
The invention replaces persistent quaternary ammonium compounds with a biodegradable acid system (citric acid and formic acid) that provides comparable anti-bacterial performance but degrades harmlessly in the environment, eliminating long-term environmental contamination.
