Solution Overview
Problem
Current methods for extracting bioactive botanical ingredients from plants are inconsistent, unstable, and often use harsh chemicals, leading to loss of potency, contamination, and safety concerns, failing to meet cosmetic industry standards for quality and consistency.
Innovation Solution
A method involving the extraction of a membrane fraction and cell serum fraction from fresh plant biomass, using a stabilizing agent to create a bioactive botanical cosmetic composition with antiproteolytic and cell growth inhibition activities, enhancing ant-inflammatory and antioxidant properties, and ensuring microbial safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current extraction methods are used to obtain botanical ingredients, then extraction efficiency is achieved, but bioactivity potency is lost and consistency deteriorates
Solution Approach 1:
The patent applies parameter changes by controlling pH levels (adjusting to specific ranges like pH 2-4 for acid treatment or pH 8-10 for base treatment), temperature parameters (maintaining 4-25°C for cold processing), and pressure parameters during extraction. These controlled parameter changes enable consistent extraction of bioactive compounds while preserving their potency across different batches, resolving the contradiction between extraction efficiency and bioactivity consistency.
2Manufacturing precision
If harsh chemical solvents are used to refine botanical extracts, then purity is improved, but safety and bioactivity are compromised
Solution Approach 1:
The patent uses food-grade acids (citric acid, acetic acid) and bases (sodium hydroxide, potassium hydroxide) as intermediary substances to adjust pH and precipitate impurities. These intermediaries are safe, biodegradable, and effective at removing contaminants without introducing harmful chemicals, thus achieving high purity while maintaining safety and preserving bioactivity.
3Adaptability or versatility
If botanical ingredients are used to create natural cosmetic formulations, then consumer appeal is improved, but stability and shelf life deteriorate
Solution Approach 1:
The patent applies preliminary action by treating botanical extracts with acids or bases immediately after extraction to adjust pH and precipitate unwanted impurities. This preliminary treatment stabilizes the extract composition before further processing or storage, preventing degradation and microbial growth, thus extending shelf life while maintaining the natural appeal of the product.
4Manufacturing precision
If standard extraction procedures are applied to ensure quality control, then manufacturing consistency is improved, but full spectrum of bioactivities is not delivered
Solution Approach 1:
The patent applies segmentation by separating the extraction process into distinct stages: initial extraction, pH adjustment, selective precipitation of different compound classes, and sequential filtration. This segmented approach allows recovery of different bioactive fractions (proteins, polysaccharides, phenolics) that would otherwise be lost in standard single-step extraction, delivering the full spectrum of bioactivities with consistent quality.
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 method yields stable, consistent, and safe bioactive botanical cosmetic compositions that meet industry standards, maintaining bioactivity and improving skin health through enhanced ant-inflammatory and antioxidant effects.
Implementation Method 1
The membrane fraction has antiproteolytic activity, cell growth inhibition activity, and/or both antiproteolytic and cell growth inhibition activities. The antiproteolytic activity is due to inhibition of at least one proteinase
Implementation Method 2
The cell growth inhibition activity is due to inhibition of proliferation of at least one type of cell
