Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current detergents face challenges in effectively removing surfactant- or enzyme-sensitive soiling from textiles, particularly in the absence of enzymes or bleaching agents, where traditional surfactants may not suffice.
Innovation Solution
A combination of polyalkoxylated amines, alcohol polyalkoxylates, and polyalkoxylated polyalkyleneimines is used to enhance the primary detergency of detergents, creating a formulation that can effectively remove surfactant- or enzyme-sensitive stains without the need for enzymes or bleaching agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surfactants are used alone, then the detergent formulation is simple, but the removal of surfactant- or enzyme-sensitive soiling is insufficient
Solution Approach 1:
The patent applies composite materials by combining three specific polymeric substances (polyalkoxylated amine, alcohol polyalkoxylate, and polyalkoxylated polyalkyleneimine) with defined molecular weight ranges to create a synergistic detergent formulation. This composite approach enhances the removal of surfactant- or enzyme-sensitive soiling beyond what traditional surfactants can achieve alone, while maintaining a structured and definable formulation system.
Solution Approach 2:
The patent employs parameter changes by specifying precise molecular weight ranges for each polymeric component (e.g., polyalkoxylated amine with Mw 600-10,000 g/mol, alcohol polyalkoxylate with Mw 600-10,000 g/mol, and polyalkoxylated polyalkyleneimine with Mw 500-50,000 g/mol). These controlled parameter variations optimize the detergency performance while managing formulation complexity through defined specifications.
2Reliability
If enzymes or bleaching agents are used, then the removal of tough stains is improved, but the detergent becomes less effective when these agents are absent
Solution Approach 1:
The patent extracts and replaces the function of enzymes and bleaching agents by using a combination of polymeric substances that can effectively remove surfactant- or enzyme-sensitive soiling without requiring these biological or oxidative agents. This allows the detergent to maintain high detergency performance in formulations that are free from enzymes or bleaching agents, providing an alternative mechanism for stain removal.
Solution Approach 2:
The polymeric substance combination serves multiple functions: it enhances primary detergency, removes surfactant- or enzyme-sensitive soiling, and provides effective performance whether or not enzymes or bleaching agents are present in the formulation. This multi-functionality increases adaptability across different detergent formulations and washing conditions.
3Reliability
If high-molecular-weight polymers are used, then the primary detergency is enhanced, but the solubility and handling become more difficult
Solution Approach 1:
The patent optimizes the balance between detergency enhancement and solubility by carefully controlling the molecular weight parameters of each polymeric component. The polyalkoxylated amine is specified with Mw 600-10,000 g/mol, the alcohol polyalkoxylate with Mw 600-10,000 g/mol, and the polyalkoxylated polyalkyleneimine with Mw 500-50,000 g/mol. These parameter ranges ensure sufficient polymer size for detergency improvement while maintaining adequate solubility in aqueous detergent formulations.
Solution Approach 2:
The patent applies local quality by introducing alkoxyl groups (ether linkages) at specific locations within the polymeric structures. These alkoxylated regions provide hydrophilic character that enhances water solubility and handling properties, while the remaining polymer backbone maintains the molecular weight and structural characteristics necessary for primary detergency enhancement. This localized modification optimizes both performance and processability.
