Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern detergents, particularly high-concentration liquid detergents, face challenges in storage stability and cleaning performance due to their optical and rheological properties, which can lead to intolerance and suboptimal stain removal, while also requiring simplified handling and sustainable packaging solutions.
Innovation Solution
A detergent portion unit with a fluent, water-soluble preparation containing 20-80% surfactants, 2-15% enzyme preparation, 5-30% 1,2-octandiol, and specific organic solvents, optimized for improved washing performance and storage stability, using a combination of anionic and non-ionic surfactants, fatty acids, and washing-active polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high concentration of active ingredients is used in detergent preparation, then cleaning performance and productivity are improved, but storage stability and compatibility deteriorate due to intolerance between ingredients
Solution Approach 1:
The patent changes the chemical parameters of the detergent preparation by incorporating 1,2-octanediol at concentrations of 0.0001 to 9 wt.%, which modifies the molecular interactions between ingredients. This parameter change enables high concentrations of surfactants (20-80 wt.%) and other active ingredients to coexist without intolerance, resolving the contradiction between cleaning performance and storage stability
Solution Approach 2:
The patent creates a composite detergent system combining multiple ingredient classes (surfactants, fatty acids, polymers, enzymes, and 1,2-octanediol) in specific proportions. This composite approach allows the ingredients to work synergistically, maintaining storage stability while achieving high cleaning performance through concentrated formulation
2Productivity
If high concentration of active ingredients is used in detergent preparation, then cleaning performance is improved, but optical and rheological properties deteriorate affecting product appearance and flowability
Solution Approach 1:
The patent adjusts rheological parameters by adding 1,2-octanediol and organic solvents (5-30 wt.%), which modify the flow characteristics and viscosity of the concentrated detergent preparation. This maintains free-flowing properties despite high active ingredient concentration, and optical parameters are optimized through proper ingredient selection and concentration control
3Loss of energy
If miniaturization of packaging is implemented, then transport efficiency and sustainability are improved, but handling and dosing convenience may deteriorate
Solution Approach 1:
The patent changes the concentration parameter of the detergent preparation to highly concentrated formulations, which reduces the volume required for each dose. This enables miniaturized packaging while maintaining effective cleaning performance, thereby improving transport efficiency without compromising handling convenience
Solution Approach 2:
The patent divides the detergent into individual portion units (sachets or capsules), each containing a optimized concentration of active ingredients. This segmentation allows compact packaging while ensuring consistent dosing and easy handling, as each unit is self-contained and portable
