Walnut Oil–Solubilized Ash Bark Cosmetic Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions fail to effectively address skin aging, reduce carbonylation of skin proteins, improve skin barrier function, enhance hydration, and provide comprehensive anti-inflammatory, antioxidant, and anti-microbial benefits, particularly due to suboptimal ingredient ratios and solubility issues.
Innovation Solution
A specific formulation comprising 1 to 30 wt% Fraxinus Excelsior Ash bark extract, 60 to 80 wt% Juglans Regia walnut seed oil, 5 to 30 wt% Polyglyceryl-4 oleate, and 0.1 to 1 wt% Tocopherol, optimized through a process involving microwave and ultrasound treatment with a co-extractant, enhances the extraction and stability of polyphenols, providing improved anti-aging and skin health benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Fraxinus excelsior bark extract and juglans regia seed oil are used in existing cosmetic compositions, then moisturizing and nourishing effects are provided, but anti-aging effects and skin barrier restoration are insufficient
Solution Approach 1:
The patent optimizes the concentration parameters of key ingredients: Fraxinus excelsior bark extract (0.01-10 wt%), juglans regia seed oil (5-50 wt%), and polyglyceryl-4 oleate (1-20 wt%). These specific parameter ranges maximize polyphenol extraction efficiency and skin penetration, thereby enhancing anti-aging effects and skin barrier restoration capabilities simultaneously
Solution Approach 2:
Polyglyceryl-4 oleate is introduced as a co-extractant and solubilizing agent that mediates between the hydrophobic polyphenols in ash bark and the aqueous environment. This intermediary substance improves the solubility and bioavailability of active ingredients, enhancing both anti-aging and skin barrier restoration effects
2Productivity
If polyphenols are extracted from Fraxinus excelsior bark using conventional methods, then extraction is achieved, but extraction efficiency and polyphenol stability are insufficient
Solution Approach 1:
The patent performs preliminary optimization of extraction parameters including using polyglyceryl-4 oleate as a pre-solubilizing agent, controlling pH levels, and adjusting temperature before the main extraction process. This preliminary action enhances polyphenol solubility and stability, leading to higher extraction efficiency and better preservation of active compounds
Solution Approach 2:
The patent uses a composite extraction system combining polyglyceryl-4 oleate (a non-ionic surfactant) with juglans regia seed oil. This composite material system synergistically enhances polyphenol extraction efficiency while maintaining polyphenol stability through the combined properties of the surfactant and oil
3Quantity of substance
If conventional extraction methods are used without co-extractants, then extraction process is simple, but polyphenol solubility and extraction yield are low
Solution Approach 1:
Polyglyceryl-4 oleate serves as an intermediary co-extractant that facilitates polyphenol solubilization without requiring complex extraction equipment. This single additive component significantly boosts polyphenol content in the extract while maintaining relatively simple process complexity
Solution Approach 2:
The patent modifies the chemical parameter of the extraction system by adding polyglyceryl-4 oleate, which changes the solubility characteristics of the system. This parameter change dramatically increases polyphenol extraction yield without requiring complex multi-step processes or specialized equipment
