Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
L-ascorbic acid solutions are unstable in aqueous solutions due to oxidation, limited solubility, and rapid decomposition, which hinders its effective use in medical and cosmetic applications.
Innovation Solution
Compositions comprising L-ascorbic acid combined with Vitis Vinifera extract, resveratrol, melatonin, and polyphenols, along with polymeric ethers and thiosulfates, enhance stability and bioavailability, allowing for higher concentrations and improved intracellular penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If L-ascorbic acid is dissolved in aqueous solution, then it becomes soluble and bioavailable, but it quickly oxidizes and decomposes
Solution Approach 1:
The patent introduces oxygen-scavenging compounds (such as vitamin E, ferulic acid, or other antioxidants) as intermediary substances that protect L-ascorbic acid from oxidation by reacting with oxygen or free radicals first. This mediator approach allows L-ascorbic acid to remain stable in aqueous solution without immediate decomposition
Solution Approach 2:
The patent creates a composite formulation combining L-ascorbic acid with stabilizing agents, penetration enhancers, and other functional components. This composite approach allows the system to simultaneously achieve solubility, stability, and bioavailability that individual components cannot provide alone
2Quantity of substance
If L-ascorbic acid concentration is increased for better efficacy, then therapeutic effect improves, but oxidation and decomposition accelerate
Solution Approach 1:
Oxygen-scavenging compounds are incorporated at specific concentrations to protect high levels of L-ascorbic acid from oxidation. These intermediaries create a protective environment that enables higher stable concentrations of vitamin C in the formulation
Solution Approach 2:
The patent modifies solution parameters such as pH level, ionic strength, and presence of chelating agents to create conditions where high concentrations of L-ascorbic acid remain stable. By controlling these parameters, the formulation maintains both high concentration and reliability
3Stability of the object's composition
If L-ascorbic acid is stabilized in non-aqueous solvents, then stability improves, but intracellular penetration decreases
Solution Approach 1:
The patent adjusts the pH of the aqueous solution to match or be slightly lower than the pH of skin and biological tissues. This pH optimization enhances both stability and penetration, as the protonated form of L-ascorbic acid at lower pH has better membrane permeability while remaining stable in the formulation
Solution Approach 2:
Penetration enhancers such as fatty acids, surfactants, or other membrane-active compounds are introduced as intermediaries that facilitate the transport of L-ascorbic acid across cell membranes. These mediators temporarily interact with the membrane structure to allow vitamin C entry without compromising the stability of the aqueous formulation
