Solid composition for textile treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bleaching agents in solid detergents are stable, but their incorporation into liquid detergents is challenging due to thermal instability, especially when combined with organic compounds, leading to decomposition and reduced effectiveness.
Innovation Solution
A solid bleaching composition with a high concentration of peroxide compounds, stabilized by hydrogen carbonate and organic bleach activators, is formulated to maintain stability and enhance washing performance, even in liquid detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If a high concentration of peroxide compound is used in solid composition, then the volume is reduced and packaging efficiency is improved, but the composition becomes thermally unstable and decomposes at storage temperatures above 35°C
Solution Approach 1:
Sodium bicarbonate acts as an intermediary substance that mediates between the peroxide compound and organic compounds. It provides a stabilizing effect by controlling the chemical environment, preventing direct harmful interactions while allowing the high concentration formulation to remain thermally stable during storage
Solution Approach 2:
The invention changes the chemical parameters of the composition by introducing sodium bicarbonate, which alters the pH and chemical reactivity environment. This parameter change allows the peroxide compound to maintain stability at high concentrations without decomposing at temperatures above 35°C
2Reliability
If organic compounds are added to enhance washing performance, then the effectiveness on bleachable stains is improved, but the peroxide compound becomes unstable and decomposes
Solution Approach 1:
Sodium bicarbonate serves as a protective intermediary that allows organic compounds to coexist with peroxide compounds in the same composition. It creates a chemical buffer system that prevents premature decomposition while maintaining the bleaching effectiveness during the washing process
3Stability of the object's composition
If conventional bleaching agents are incorporated into liquid detergents, then the stability is improved, but the concentration must be reduced due to decomposition issues
Solution Approach 1:
By changing the chemical parameters through sodium bicarbonate addition, the invention enables liquid detergent formulations to maintain high peroxide compound concentrations without the decomposition issues that normally limit concentration in liquid systems
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 ensures storage stability and improved washing performance by maintaining the effectiveness of bleaching agents, preventing thermal decomposition and ensuring safe use in textile treatment.
Implementation Method 1
a solid composition with a bleaching agent content, for example, peroxide compounds, of at least 30 wt% is thermally unstable upon contact with organic compounds, particularly at storage temperatures above 35°C, and decomposes with the release of heat
Implementation Method 2
The effectiveness of removing bleachable stains, such as colored fruit and vegetable stains, is a key quality criterion for a laundry detergent. During the bleaching process, the bleachable stain should be bleached and/or removed.
Implementation Method 3
Upon contact with water, the aforementioned compositions are released from the portion acting as a dosing unit
