Liquid detergent composition for textile products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid detergent compositions for textiles lack effectiveness in imparting texture and detergency, especially against stains, particularly at low temperatures, due to suboptimal ratios of internal olefin sulfonates and the absence of suitable organic solvents with hydroxy groups.
Innovation Solution
A liquid detergent composition containing internal olefin sulfonates with specific carbon atom ranges and sulfonate group positions, combined with an organic solvent having a hydroxy group, to enhance texture and detergency on textiles, even at low washing temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional internal olefin sulfonates are used in liquid detergent compositions, then the detergent composition can be formulated, but the effectiveness in imparting texture and detergency against stains is insufficient
Solution Approach 1:
The patent applies parameter changes by specifying precise compositional parameters: internal olefin sulfonate content (10-60% by mass), hydroxy form/olefin form ratio (0.3-5.0), and specific carbon atom ranges (16-22). These parameter optimizations resolve the contradiction by achieving superior detergency and texture effects while maintaining formulation feasibility through defined concentration ranges.
Solution Approach 2:
The patent employs composite materials by combining internal olefin sulfonates with specific physical-chemical properties (hydroxy form, olefin form, carbon chain length) to create a synergistic detergent composition. This composite approach enhances both texture impartment and stain removal effectiveness while keeping the formulation process manageable.
2Reliability
If the ratio of hydroxy form to olefin form of internal olefin sulfonate is not optimized, then the formulation is simpler, but the texture impartment and detergency performance deteriorate
Solution Approach 1:
The patent resolves this contradiction by establishing specific parameter ranges: hydroxy form/olefin form ratio between 0.3-5.0 and internal olefin sulfonate content between 10-60% by mass. These parameter definitions enable effective texture impartment and detergency while providing clear formulation guidelines that manage composition control complexity.
3Reliability
If conventional surfactant compositions are used, then the detergent composition can be prepared, but the performance at low washing temperatures is insufficient
Solution Approach 1:
The patent achieves low temperature performance through parameter optimization: specifying internal olefin sulfonates with 16-22 carbon atoms and controlling the hydroxy form/olefin form ratio within 0.3-5.0. These parameter changes enhance cold water effectiveness while maintaining straightforward formulation procedures.
