Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergents often contain non-biodegradable components and may not achieve optimal cleaning performance due to the lack of synergistic effects among their components, leading to environmental persistence and reduced efficacy.
Innovation Solution
A detergent composition comprising a citrate buffer, surfactant component, and chelator component, all of which are biodegradable, with a pH range of 6.5 to 9, creating a synergistic cleaning system that includes specific surfactant mixtures and a chelator like glutamic acid N,N-diacetic acid tetrasodium salt, enhancing cleaning performance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional detergents are used, then cleaning performance is achieved, but environmental persistence occurs due to non-biodegradable components
Solution Approach 1:
The patent changes the chemical composition parameters by using biodegradable surfactants (alkyl polyglucosides, alkyl ethers, alkyl esters) instead of traditional non-biodegradable surfactants, while adjusting the pH to 6.5-9.0 to optimize cleaning performance. This parameter change resolves the contradiction by maintaining effectiveness while improving environmental compatibility.
Solution Approach 2:
The patent creates a composite detergent formulation combining multiple biodegradable surfactant types (anionic, nonionic, and amphoteric) with specific ratios, along with biodegradable chelators and builders. This composite approach achieves synergistic cleaning performance while ensuring all components are biodegradable, thus resolving the contradiction between performance and environmental persistence.
2Object-affected harmful factors
If biodegradable components are used, then environmental friendliness is improved, but cleaning performance may be reduced
Solution Approach 1:
The patent merges multiple types of biodegradable surfactants (anionic alkyl polyglucosides, nonionic alkyl ethers, and amphoteric betaines) into a single formulation. This combination creates synergistic effects that enhance cleaning performance while maintaining the environmental benefits of biodegradability, thus resolving the contradiction.
Solution Approach 2:
The patent optimizes the concentration ratios of different biodegradable surfactants and adjusts the pH to 6.5-9.0 to maximize cleaning effectiveness. By carefully controlling these parameters, the formulation achieves performance comparable to or exceeding traditional detergents while using only biodegradable components.
3Object-affected harmful factors
If pH is adjusted to 6.5-9, then corrosion is reduced, but cleaning efficacy may be compromised
Solution Approach 1:
The patent adjusts the pH to the neutral range of 6.5-9.0 using appropriate buffers and alkaline agents, which reduces corrosion on metal surfaces. Simultaneously, the formulation compensates for the milder pH by optimizing surfactant concentrations and selecting surfactant types that maintain high cleaning efficacy at neutral pH, thus resolving the contradiction between corrosion reduction and cleaning efficacy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves superior cleaning performance, stability over time, and environmental friendliness by utilizing biodegradable components, effectively removing soils and microbes while maintaining pH stability and reducing corrosion.
Implementation Method 1
a citrate buffer; wherein a pH of the detergent composition is in a range of from about 6.5 to about 9
Implementation Method 2
Detergents work by reducing the surface tension of water, effectively allowing it to more easily penetrate into surfaces and lift away dirt and oils
Implementation Method 3
a chelator component, wherein a pH of the detergent composition is in a range of from about 6.5 to about 9
