Detergent composition for textile products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent compositions for textile products face challenges in maintaining effective cleaning performance, especially when using water with high hardness, due to limitations in surfactant combinations and ratios.
Innovation Solution
A detergent composition combining an internal olefin sulfonate with 16 to 18 carbons and one or more anionic surfactants, such as alkyl sulfate or alkane sulfonate, optimized in terms of carbon chain length and mass ratios to enhance cleaning properties and resistance to water hardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surfactant combinations are used, then general cleaning ability is achieved, but cleaning performance deteriorates when water hardness is high
Solution Approach 1:
The patent combines internal olefin sulfonate (16-18 carbons) with specific anionic surfactants (alkyl sulfate or alkane sulfonate with 12-14 carbons) to create a composite surfactant system. This composite structure provides synergistic effects where the internal olefin sulfonate maintains effectiveness in hard water while the anionic surfactants contribute to overall cleaning performance, resolving the contradiction between general cleaning ability and resistance to water hardness.
Solution Approach 2:
The patent optimizes specific parameters including carbon chain lengths (16-18 for internal olefin sulfonate, 12-14 for anionic surfactants), mass ratios (0.05-0.50 for internal olefin sulfonate to 0.50-1.95 for anionic surfactants), and surfactant composition ratios (20-80 mass% internal olefin sulfonate). These parameter optimizations enable the detergent to maintain reliable cleaning performance while resisting the harmful effects of water hardness.
2Reliability
If internal olefin sulfonate with specific carbon number is used, then cleaning properties are improved, but formulation complexity increases
Solution Approach 1:
The patent specifies precise parameter ranges (16-18 carbons for internal olefin sulfonate, 12-14 carbons for anionic surfactants, specific mass ratios) to achieve optimal cleaning properties. By defining these clear parameter boundaries, the patent simplifies the formulation process while maintaining high cleaning effectiveness, resolving the contradiction between improved cleaning properties and formulation complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves superior cleaning performance on textile products even with hard water, maintaining effectiveness through a synergistic surfactant structure that improves stain removal and resistance to water hardness.
Implementation Method 1
anionic surfactants, particularly alkylbenzene sulfonates, olefin sulfonates, and further, internal olefin sulfonates obtained using as a raw material an internal olefin having a double bond not at the end of the olefin chain but inside the olefin chain, and nonionic surfactants containing an oxyalkylene group having 2 to 3 carbons have been heretofore widely used as household and industrial detergent components
