Peach Flower Aqueous Extract for Skin Anti-Aging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic products fail to effectively address signs of aging and photo-aging of the skin and keratinous appendages using natural ingredients, as they often lack potent antioxidants and agents that stimulate connective tissue restoration.
Innovation Solution
A peach flower extract obtained through aqueous extraction is used in a cosmetic composition, which contains polyphenolic compounds and flavonoids that act as antioxidants, thereby increasing SIRT2 expression and providing anti-aging benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods are used, then extraction efficiency is improved, but antioxidant content and SIRT2 activation capability deteriorate
Solution Approach 1:
The patent changes the extraction parameters by using aqueous extraction at lower temperatures (4-25°C) instead of conventional high-temperature methods, and by controlling pH levels to maintain polyphenol stability. This preserves the antioxidant content while achieving effective extraction through optimized parameter conditions rather than relying on high temperature and energy input.
2Speed
If high temperature extraction is used, then extraction speed is improved, but polyphenol stability and extract quality deteriorate
Solution Approach 1:
The patent optimizes extraction parameters by conducting extraction at lower temperatures (4-25°C) and controlling pH levels to prevent polyphenol degradation. This approach maintains polyphenol stability while achieving effective extraction through extended contact time and optimized chemical conditions rather than relying on high temperature.
Solution Approach 2:
The patent performs preliminary optimization of extraction conditions by adjusting pH and temperature before the actual extraction process. This preliminary preparation ensures that the extraction environment is optimized for polyphenol stability from the start, preventing degradation before it can occur during extraction.
3Manufacturing precision
If conventional extraction methods are used, then extraction completeness is improved, but extract stability and shelf life deteriorate
Solution Approach 1:
The patent changes the extraction parameters by using controlled low-temperature aqueous extraction and pH adjustment to prevent polyphenol oxidation and degradation. This produces an extract that is both complete in its active ingredient content and stable for long-term storage, resolving the contradiction between extraction completeness and extract stability.
