Solution Overview
Problem
Existing oxidizing and bleaching agents, such as chlorine bleaches and oxygen bleaches, face issues with stability and effectiveness, particularly in liquid compositions, and there is a need for improved storage stability and oxidative decomposition activity.
Innovation Solution
A liquid composition containing an isoxazolium salt and water, maintained at an acidic pH, which includes hydrogen peroxide for enhanced oxidative decomposition activity and stability, suitable for use as an oxidizing or bleaching agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional oxidizing agents (chlorine bleaches, oxygen bleaches) are used, then bleaching function is provided, but storage stability and effectiveness deteriorate
Solution Approach 1:
The patent changes the chemical parameters by introducing isoxazolium salts with specific molecular structures (containing isoxazole rings and various alkyl/aryl groups) and controlling pH levels, which fundamentally alters the stability and oxidative properties of the bleaching composition
Solution Approach 2:
The patent creates a composite system combining isoxazolium salts with hydrogen peroxide and other oxidizing agents, where the synergistic interaction between components enhances both storage stability and oxidative decomposition activity simultaneously
2Reliability
If isoxazolium salt is stored in neutral solution, then ease of storage is maintained, but storage stability deteriorates
Solution Approach 1:
The patent specifies that the isoxazolium salt must be stored in an acidic solution with controlled pH (typically pH 2-6), which fundamentally changes the storage conditions required and improves storage stability by preventing degradation pathways that occur in neutral or basic solutions
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 exhibits excellent storage stability and oxidative decomposition activity, effectively functioning as an oxidizing or bleaching agent, particularly for applications like bleaching hard articles and mold removal, with improved safety and efficiency.
Implementation Method 1
In oxygen bleaches, activated bleaching species (organic peroxy acids or the like) are produced by reacting oxidizing agents (for example, hydrogen peroxide) with organic acid esters or the like as bleach activators, and objects are oxidized and bleached therewith
