Keratin Bleaching Agent Homogeneity via Segmented Xanthan Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available bleaching agents for hair often suffer from poor miscibility and uneven bleaching effects due to incomplete homogenization, leading to concentration fluctuations and undesirable bleaching results. Additionally, their viscosity can be unstable, causing handling issues and making it difficult to achieve a consistent bleaching process.
Innovation Solution
A bleaching agent formulation comprising two separately packaged preparations, where one contains persulfate and is xanthan gum-free, and the other contains xanthan gum, which improves miscibility and viscosity, allowing for a transparent, homogeneously mixed application that enables visual control of the bleaching process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If emulsions are used to improve flowability and spreadability, then the preparation can be easily distributed over the hair, but the rheological properties change during storage affecting stability and miscibility
Solution Approach 1:
The patent changes the chemical composition parameters by using clear gel bases instead of emulsions, and by carefully controlling the pH range (8.5-10.5) and ingredient concentrations to maintain stable rheological properties throughout storage while ensuring adequate flowability for application
Solution Approach 2:
The patent employs composite formulations combining multiple ingredients (hydrogen peroxide, persulfates, alkalizing agents, and clear gel bases) that work together to provide both the desired flowability for easy application and stable rheological properties during storage, avoiding the instability issues of emulsion-based systems
2Ease of operation
If the preparation is made transparent for visual control, then the bleaching process can be monitored without removal, but the formulation becomes more complex
Solution Approach 1:
The patent changes the optical properties by selecting transparent clear gel bases and using ingredients that remain transparent in solution, allowing visual monitoring of the bleaching process while managing formulation complexity through careful ingredient selection rather than complex additive systems
3Stability of the object's composition
If separate packaging is used to maintain stability, then the active ingredients remain stable during storage, but complete homogenization becomes difficult leading to uneven bleaching
Solution Approach 1:
The patent divides the bleaching agent into separate stable components (oxidizing agents, alkalizing agents, and clear gel bases) that are packaged separately to maintain stability, but are designed to mix completely and homogeneously upon combination through compatible formulation chemistry and appropriate mixing instructions
Solution Approach 2:
The patent ensures homogeneous mixing by using clear gel bases as a common medium that promotes complete miscibility of all ingredients, and by formulating components with compatible solubility and viscosity characteristics that enable uniform distribution when mixed
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 formulation ensures better bleaching results with improved miscibility and viscosity, allowing for uniform application and visual monitoring of the bleaching process without removing the agent from the hair, enhancing user handling and stability.
Implementation Method 1
The preparation according to the invention has improved properties in terms of viscosity. A further advantage of the bleaching agent according to the invention is its transparency
Implementation Method 2
The oxidizing agents contained in bleaching products are able to lighten the hair fiber through the oxidative destruction of the hair's own pigment melanin
Implementation Method 3
the addition of a natural polymer to the oxidizing agent preparation leads to a flowable preparation, which allows easy incorporation of a powdery preparation and good homogenization of the two components into a ready-mixed application mixture
Implementation Method 4
The provision of transparent bleaching agents consequently leads to improved handling of the bleaching agent and simplification of use. It is not necessary to remove the bleaching agent from the fiber. Instead, the transparency of the application mixture allows a direct, visual assessment of the discoloration process
