Aqueous Oxidizing Composition Stabilization via Magnesium Salts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aqueous oxidizing compositions used in hair cosmetics face issues with peroxide instability, leading to packaging swelling and increased hair damage due to reactive oxygen, especially when high viscosity compositions are stored, causing splash and stability problems.
Innovation Solution
Incorporating magnesium salts, particularly magnesium sulphate, into the compositions to enhance peroxide stability, along with optional additional stabilizing agents like salicylic acid and oxyquinoline, to reduce hair damage and improve storage stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oxidizing compositions are stored in packaging, then oxygen is produced through decomposition which increases internal pressure, but this leads to swelling of packaging material and potential product splash
Solution Approach 1:
The patent introduces an intermediary substance (e.g., a stabilizing agent or pressure-regulating component) that mediates between the decomposing oxidizing agent and the packaging material, controlling oxygen release and pressure buildup to prevent packaging swelling and product splash while maintaining storage stability
Solution Approach 2:
The patent modifies chemical parameters of the oxidizing composition (such as pH, concentration, or adding stabilizers) to change the decomposition rate and oxygen evolution characteristics, thereby controlling internal pressure buildup during storage and preventing packaging failure
2Reliability
If high viscosity compositions are used, then product performance is improved, but oxygen cannot easily leave the composition leading to increased internal pressure
Solution Approach 1:
The patent adjusts physical parameters such as viscosity by adding specific ingredients or modifying composition formulation, enabling oxygen to escape more easily from high-performance compositions without sacrificing product efficacy, thus reducing internal pressure during storage
3Reliability
If peroxide stability is not stabilized, then reactive oxygen concentration increases, but this leads to excessive hair damage
Solution Approach 1:
The patent introduces stabilizing agents as intermediary substances that interact with reactive oxygen species, controlling their concentration and reactivity to maintain oxidizing efficiency for hair treatment while preventing excessive hair damage through moderated oxygen release

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 use of magnesium salts significantly improves peroxide stability, reducing hair damage and packaging issues, while maintaining effective hair coloring and shaping processes.
Implementation Method 1
Oxidizing agents included in such compositions undergo decomposition wherein oxygen is produced
Implementation Method 2
stabilization of oxidizing agent leads to less hair damage as reactive oxygen concentration in the composition and/or in the mixture is reduced
