Liquid Detergent Composition for Low-Temperature Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid detergent compositions for textile products face challenges in preventing solid matter formation and separation when exposed to low temperature environments, as they lack stability and effective detergent properties.
Innovation Solution
A liquid detergent composition containing an internal olefin sulfonate with a specific mass ratio of sulfonate groups at different positions and an organic solvent with a hydroxy group, which maintains stability and detergent efficacy even at low temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional liquid detergent compositions are used, then detergent properties are provided, but solid matter precipitates and separation occurs at low temperatures
Solution Approach 1:
The patent applies parameter changes by carefully controlling the carbon atom number (14-16) of the internal olefin sulfonate and the mass ratio of sulfonate group positions (IO-1S)/(IO-2S) between 0.50-4.2. These specific parameter ranges optimize the molecular structure to prevent crystallization at low temperatures while maintaining detergent effectiveness, thereby resolving the contradiction between providing detergent properties and preventing solid matter precipitation.
Solution Approach 2:
The patent uses composite materials by combining internal olefin sulfonate with specific organic solvents having hydroxy groups (such as propylene glycol, ethylene glycol, or their derivatives). This composite formulation creates a synergistic effect where the organic solvent acts as a co-solvent to further prevent crystallization and separation at low temperatures, enhancing the overall stability while maintaining cleaning performance.
