Gas-Fermentation Surfactant Odor for Dishwash Detergent Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine dishwash detergents face challenges in providing a reduced environmental impact without compromising cleaning efficiency or stability, while consumers distrust on-pack claims of reduced environmental impact and seek authentic sensory cues.
Innovation Solution
A machine dishwash detergent composition using surfactants derived from gas-fermentation, with a C8-22 alkyl chain and 2 to 100 ethoxylate units, offering a distinct headspace odor that differentiates from petrochemically derived surfactants, providing an authentic link to reduced environmental impact and enhancing consumer trust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If surfactants are derived from petrochemical sources, then manufacturing cost and stability are maintained, but environmental impact increases and consumer trust decreases
Solution Approach 1:
The patent changes the source parameter of surfactant production from petrochemical to gas-fermentation derived precursors. This parameter change reduces environmental impact while the controlled ethoxylate unit range (2-100) and alkyl chain length (C8-22) maintain product stability and performance characteristics.
2Loss of information
If on-pack claims about reduced environmental impact are made, then consumer information is provided, but consumer trust is lost due to perceived lack of authenticity
Solution Approach 1:
The patent uses odor as a sensory indicator (analogous to color changes) where the distinctive fatty/waxy headspace odor provides authentic, detectable evidence of gas-fermentation derived surfactants. This sensory cue allows consumers to verify environmental claims without relying solely on packaging information.
3Object-affected harmful factors
If surfactants with reduced environmental impact are used, then environmental benefits are achieved, but cleaning efficiency may be compromised
Solution Approach 1:
The patent optimizes parameters including alkyl chain length (C8-22), ethoxylate units (2-100), and surfactant concentration (0.1-20 wt%) to ensure that gas-fermentation derived surfactants achieve both reduced environmental impact and maintained cleaning efficiency through proper molecular structure and formulation.
4Loss of information
If ingredient listings are extended to provide full transparency, then consumer understanding improves, but product complexity increases
Solution Approach 1:
The patent extracts and highlights the most significant ingredient information (surfactant source and key components) while maintaining a relatively concise ingredient list. The distinctive odor provides additional verification without requiring extensive textual explanation, balancing transparency with simplicity.
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 surfactants derived from gas-fermentation offer a unique, fatty/waxy odor that is difficult to adulterate, providing an authentic sensory cue to consumers, enhancing trust and maintaining cleaning efficiency and stability without lengthening the ingredient list.
Implementation Method 1
the surfactant is made by a manufacturing process including the step of using one or more surfactant-precursors obtained via gas-fermentation
