Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no commercial product comprising hyaluronic acid or its derivative in an anhydrous system that is both transparent and stable over time, which is desirable for cosmetic applications.
Innovation Solution
A composition containing acetylated hyaluronic acid or its salt with an acetylation degree of 0.5 to 1 and propylene glycol, formulated without water, providing a transparent and stable anhydrous system for caring for keratin materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hyaluronic acid is used in conventional aqueous systems, then moisturizing effect is achieved, but transparency and long-term stability cannot be simultaneously obtained in anhydrous systems
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of hyaluronic acid through acetylation, changing its degree of acetylation to between 0.5 and 1. This chemical modification alters the physical and chemical properties of hyaluronic acid, enabling it to remain stable and transparent in anhydrous cosmetic compositions while maintaining its moisturizing function.
2Stability of the object's composition
If anhydrous system is used for cosmetic composition, then transparency can be achieved, but stability over time is compromised without proper formulation
Solution Approach 1:
The patent uses composite materials by combining acetylated hyaluronic acid with specific cosmetic ingredients in an anhydrous formulation. This composite approach creates a stable system where the modified hyaluronic acid maintains both transparency and long-term stability, overcoming the limitations of conventional aqueous systems.
3Ease of manufacture
If conventional hyaluronic acid is used in cosmetic products, then moisturizing function is provided, but the product cannot be both transparent and stable in anhydrous formulation
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of hyaluronic acid through acetylation, changing its degree of acetylation to between 0.5 and 1. This chemical modification alters the physical and chemical properties of hyaluronic acid, enabling it to remain stable and transparent in anhydrous cosmetic compositions while maintaining its moisturizing function.
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 maintains transparency and stability over time, effectively caring for keratin materials such as hair and skin, offering benefits like hydration and firmness.
Implementation Method 1
by virtue of their hygroscopic properties which are characteristic of these molecules
Implementation Method 2
a humectant such as propylene glycol
