Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in finding natural, safe, and economical antioxidant substances from abundant and low-value raw materials, particularly in the development of sustainable products like food additives, pharmaceuticals, and cosmetics, where forest biomass residues like red maple and black spruce bark extracts offer potential as rich sources of bioactive molecules.
Innovation Solution
The development of extracts from the bark of Acer rubrum (Red maple) and Picea mariana (Black spruce) is used to create anti-aging compositions that inhibit elastase and collagenase enzymes, promoting skin health by enhancing collagen and elastin production, and are formulated with physiologically acceptable excipients for topical application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If forest biomass residues like red maple and black spruce bark extracts are used as sources of bioactive molecules, then the availability and cost-effectiveness of antioxidant substances is improved, but the extraction and purification processes become more complex
Solution Approach 1:
The patent extracts bioactive molecules (polyphenols, flavonoids, tannins) from forest biomass residues through solvent extraction processes. The extraction isolates the useful antioxidant substances from the complex bark material, converting waste biomass into valuable cosmetic ingredients while managing the complexity through standardized extraction protocols
Solution Approach 2:
The patent optimizes extraction parameters including solvent composition (ethanol-water mixtures), temperature, pressure, and extraction time to maximize yield of bioactive molecules while controlling process complexity. By systematically adjusting these parameters, the patent achieves efficient extraction without requiring overly complex purification systems
2Reliability
If bark extracts are used as anti-aging agents, then the effectiveness in inhibiting elastase and collagenase is improved, but the need for additional safety testing and formulation complexity increases
Solution Approach 1:
The patent utilizes the inherent bioactive compounds naturally present in bark extracts (polyphenols, flavonoids, tannins) that possess intrinsic elastase and collagenase inhibitory activities. These compounds self-regulate their anti-aging function without requiring complex synthetic formulations or additional active ingredients, thereby maintaining effectiveness while limiting formulation complexity
Solution Approach 2:
The patent optimizes the concentration ranges of bioactive compounds in the extracts and their formulation parameters to achieve effective anti-aging activity while ensuring safety. By controlling parameters such as extract concentration, solvent residue levels, and formulation pH, the patent maintains high reliability in enzyme inhibition while managing safety testing and formulation complexity
