Spray Cleaning Composition for Crystalline Grease Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning products with spray dispensers struggle to effectively remove crystalline grease while providing good initial sudsing, often requiring excessive detergent and time for soaking, which is inefficient for single-item washing under running water.
Innovation Solution
A cleaning composition housed in a spray dispenser, comprising 5% to 25% of a surfactant system with alkyl polyglucoside and amphoteric or zwitterionic co-surfactants, along with an organic solvent, which enhances initial sudsing and crystalline grease removal without relying on excessive anionic surfactants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher levels of detergent composition are applied for longer durations to remove crystalline grease, then grease removal effectiveness is improved, but washing time increases and user satisfaction decreases
Solution Approach 1:
The patent changes the chemical parameters of the detergent composition by incorporating specific solvents (alcohols, glycols, esters, ketones, or their mixtures) at optimized concentrations (0.1-20% by weight). This parameter change allows the formulation to effectively soften and remove crystalline grease at lower concentrations and shorter contact times, resolving the contradiction between grease removal effectiveness and washing time.
Solution Approach 2:
The patent creates a composite detergent system combining multiple surfactant types (anionic, nonionic, amphoteric, or zwitterionic surfactants) with specific solvents and optional additives. This composite formulation synergistically enhances grease removal capability while reducing the required application time, addressing both the reliability and time loss aspects of the contradiction.
2Ease of manufacture
If conventional spray cleaning products are formulated to provide initial sudsing, then user perception of cleaning efficacy is improved, but crystalline grease removal capability deteriorates
Solution Approach 1:
The patent applies local quality by assigning different functional roles to different components of the detergent system. Surfactants are selected and formulated to provide initial sudsing upon spray application, while solvents and co-surfactants are specifically chosen to penetrate and dissolve crystalline grease. This localized functional distribution allows both sudsing and grease removal to excel simultaneously.
Solution Approach 2:
The detergent composition is designed to perform preliminary action in two stages: first, surfactants generate immediate sudsing upon contact with the surface, providing visual feedback; second, solvents and co-surfactants work to soften and remove crystalline grease. This staged preliminary action resolves the contradiction between immediate sudsing performance and subsequent grease removal capability.
