Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry detergents fail to achieve satisfactory cleaning performance at low wash temperatures, particularly in cold water, and often compromise on grease removal or affect the quality of laundry.
Innovation Solution
A liquid laundry detergent composition containing a polyetheramine, specifically formulated with a structure that includes a mixture of polyetheramines represented by Formula (I) and Formula (II), which enhances cleaning performance at low temperatures without affecting the quality or particulate cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional surfactants are used in cold water, then the detergent composition is simple and easy to manufacture, but the grease cleaning performance is insufficient
Solution Approach 1:
The patent combines conventional surfactants with polyetheramine compounds to create a composite detergent system. The polyetheramine (0.1-10% by weight) works synergistically with anionic and nonionic surfactants to enhance grease removal at cold temperatures while maintaining formulation simplicity and manufacturing ease
Solution Approach 2:
The invention modifies the chemical composition parameters by introducing polyetheramine with specific molecular weight ranges (100-10,000) and structural characteristics. This parameter change enables effective grease cleaning at cold water temperatures (15-30°C) without compromising the overall detergent formulation complexity
2Reliability
If additives are added to enhance detergent power, then grease cleaning improves, but the quality of laundry may be adversely affected
Solution Approach 1:
The polyetheramine acts as an intermediary substance that bridges the gap between surfactant effectiveness and fabric safety. It enhances grease removal through chelating properties and micelle formation while maintaining mildness to fabrics, thus mediating between cleaning power and laundry quality protection
Solution Approach 2:
The patent carefully controls the concentration of polyetheramine (0.1-10% by weight) and its molecular weight parameters to optimize the balance between grease cleaning enhancement and fabric safety. This precise parameter control ensures improved cleaning without adverse effects on laundry quality
3Reliability
If low molecular weight amines are used, then grease removal improves, but suds suppression and fragrance stabilization are compromised
Solution Approach 1:
The patent optimizes the molecular weight parameter of polyetheramine within the range of 100-10,000 to achieve a balance between grease removal effectiveness and functional stability. This parameter optimization enables the compound to provide adequate grease cleaning while maintaining acceptable sud stability and fragrance stabilization properties
