Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid bleaching agents face issues with deterioration, deactivation, and decomposition when mixed with other components, leading to reduced effectiveness in washing, sterilization, and bleaching, and they often cause foaming and residue formation, limiting their applications.
Innovation Solution
A solid bleaching agent with a coating layer formed from alkali metal salts of aromatic carboxylic acids, acyclic dicarboxylic acids, or acyclic monocarboxylic acids, which stabilizes the bleaching agent, prevents foaming, and ensures good solubility in water without residue formation, allowing for broader application in detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solid bleaching agent is used as a mixture with other components, then the washing, sterilization, and bleaching effects are enhanced, but the solid bleaching agent reacts with other components causing deterioration, deactivation, or decomposition
Solution Approach 1:
The solid bleaching agent is separated from other detergent components by enclosing it in a coating layer, allowing the detergent to contain both the bleaching agent and other components without direct interaction. This segmentation maintains stability while enabling versatility.
Solution Approach 2:
The coating layer acts as an intermediary barrier between the solid bleaching agent and other detergent components. This intermediate layer prevents harmful reactions while allowing the components to coexist in the same detergent formulation.
2Reliability
If synthetic surfactants or fatty acid soaps are used as coating materials, then stability of the solid bleaching agent is improved, but excessive foaming occurs requiring excessive rinsing work
Solution Approach 1:
The coating material is changed from conventional surfactants and fatty acid soaps to water-soluble polymers, fundamentally changing the foaming characteristics. This parameter change eliminates excessive foam generation while maintaining the protective function of the coating layer.
Solution Approach 2:
The coating layer is formed as a composite material comprising water-soluble polymer and optionally water-soluble inorganic salt, combining the protective function with low foaming properties, unlike conventional surfactant-based coatings.
3Reliability
If paraffin wax or microcrystalline wax is used as coating material, then the solid bleaching agent is protected, but residues remain and solubility in water is poor
Solution Approach 1:
The coating material is changed from water-insoluble waxes to water-soluble polymers, fundamentally changing the solubility parameter. This ensures the coating layer dissolves completely in water during washing, eliminating residue formation while maintaining protection during storage.
Solution Approach 2:
The coating layer is designed as a temporary protective structure that serves its purpose during storage and transport, then dissolves completely during use. This disposable approach eliminates residues while providing necessary protection when needed.
4Reliability
If organic polymers such as polyoxyethylene-polyoxypropylene are used for coating, then the solid bleaching agent is protected, but reactivity occurs requiring isolation layers
Solution Approach 1:
The coating material is changed from reactive organic polymers to water-soluble polymers with different chemical properties that do not react with the solid bleaching agent. This parameter change eliminates the need for additional isolation layers, simplifying the coating structure to a single functional layer.
