Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashing detergent compositions using polyalkylene glycols suffer from poor cleaning performance, high viscosity, difficult handling, and phase separation at room and elevated temperatures, which affects their stability and consumer appeal.
Innovation Solution
A dishwashing detergent composition comprising at least one fatty acid glucamide and at least one fatty alcohol alkoxylate, with a water content of less than 20 wt.%, which provides improved phase-stability, reduced production costs, and enhanced sustainability and handling characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If polyalkylene glycols are used as thickening agents, then the composition provides a gel structure, but the composition exhibits phase separation at room temperature and high temperatures
Solution Approach 1:
The patent changes the chemical composition parameters by replacing polyalkylene glycol with a specific ratio of fatty alcohol alkoxylate to fatty acid glucamide. This parameter change maintains the gel structure while eliminating phase separation, as the new composition system creates a stable microemulsion that does not separate at room or elevated temperatures.
Solution Approach 2:
The patent uses a composite material system consisting of fatty alcohol alkoxylate and fatty acid glucamide in a specific ratio range (2:8 to 8:2). This composite approach combines the thickening capability of one component with the stabilizing properties of the other, achieving both gel structure and phase stability simultaneously.
2Object-affected harmful factors
If polyalkylene glycols are used as thickening agents, then the composition achieves desired viscosity, but the cleaning performance and shine performance are compromised
Solution Approach 1:
The patent applies multi-functionality by selecting ingredients that serve multiple purposes. Fatty alcohol alkoxylate and fatty acid glucamide both provide thickening/viscosity control and contribute to cleaning performance and shine, eliminating the need to choose between viscosity and cleaning efficacy that plagues single-function polyglycol systems.
3Shape
If polyalkylene glycols are used as thickening agents, then the composition provides gel consistency, but the production cost increases and handling becomes difficult
Solution Approach 1:
The patent employs cost-effective ingredients (fatty alcohol alkoxylate and fatty acid glucamide) that can be readily sourced and processed, replacing expensive polyalkylene glycols. The new formulation reduces manufacturing costs while maintaining the desired gel consistency and aesthetic profile.
4Shape
If polyalkylene glycols are used as thickening agents, then the composition maintains gel form, but the sustainability profile deteriorates due to petro-based ingredients
Solution Approach 1:
The patent changes the chemical origin parameters by substituting petrochemical-based polyalkylene glycol with bio-based fatty alcohol alkoxylate and fatty acid glucamide. This parameter change maintains the gel form while improving sustainability, as the new ingredients can be derived from renewable resources and exhibit better biodegradability.
