Detergent Composition With Dye Transfer Inhibitor Boosters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents face challenges with dye transfer inhibition, particularly when using anionic surfactants, leading to reduced performance and discolouration during laundry.
Innovation Solution
Incorporating dye transfer inhibitors, such as 1,2-heptanediol, 2,3-heptanediol, or specific dye transfer inhibitor boosters like alkanediols, glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin, or tropolone, enhances dye transfer inhibition by stabilizing the dye transfer process in detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dye transfer inhibitors are used with anionic surfactants, then detergent cleaning performance is achieved, but dye transfer inhibition performance is reduced
Solution Approach 1:
The patent extracts and eliminates the problematic interaction between conventional dye transfer inhibitors and anionic surfactants by introducing a novel class of compounds (1,2-heptanediol and 2,3-heptanediol) that do not suffer from this interaction issue, thereby resolving the contradiction while maintaining cleaning performance
Solution Approach 2:
The patent changes the chemical parameters of the dye transfer inhibitor by using specific diol compounds (1,2-heptanediol and 2,3-heptanediol) with distinct molecular structures that alter their interaction properties with anionic surfactants, improving dye transfer inhibition without the harmful interactions seen with conventional inhibitors
2Stability of the object's composition
If dye transfer inhibitors are used to prevent discolouration, then colour stability is improved, but detergent composition complexity increases
Solution Approach 1:
The patent applies multi-functionality by using 1,2-heptanediol and 2,3-heptanediol that serve both as effective dye transfer inhibitors and as compatible components with anionic surfactants, eliminating the need for separate compatibility adjustments and reducing overall formulation complexity
Solution Approach 2:
The patent creates a composite detergent system where 1,2-heptanediol and 2,3-heptanediol are combined with anionic surfactants to form a synergistic mixture that provides both cleaning and dye transfer inhibition functions without the harmful interactions that would increase complexity
