Subcritical Water Extraction of Coconut Shell Extracts for Skin Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current natural cosmetic products from plant raw materials are not fully effective in protecting and improving skin health, particularly in addressing signs of skin aging and depigmentation.
Innovation Solution
A coconut shell extract obtained by solid-liquid extraction with water in the subcritical state, containing specific phenolic compounds like trans-piceatannol, scirpusine A, scirpusine B, and hydroxybenzoic acid, is used in cosmetic compositions to improve skin condition and protect against aging and pigmentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plant raw materials are used in cosmetic products, then natural origin is achieved, but effectiveness in protecting and improving skin health is insufficient
Solution Approach 1:
The invention extracts specific bioactive compounds (polyphenols, flavonoids, terpenes) from coconut shell through solid-liquid extraction with water in subcritical state, isolating the effective components from the raw material to achieve both natural origin and high effectiveness in skin protection
Solution Approach 2:
The invention changes the extraction parameters by using water in subcritical state (temperature and pressure conditions below critical point) to optimize the extraction of bioactive compounds from coconut shell, thereby improving the concentration and effectiveness of active ingredients in the cosmetic composition
2Object-affected harmful factors
If natural plant products are used, then cosmetic safety is improved, but ability to combat skin aging and depigmentation is insufficient
Solution Approach 1:
The invention creates a composite cosmetic composition containing multiple types of bioactive compounds (polyphenols, flavonoids, terpenes) extracted from coconut shell, combining different classes of natural substances to achieve synergistic effects in combating skin aging and depigmentation while maintaining safety
Solution Approach 2:
The invention identifies and replicates the beneficial effects of known effective compounds (such as piceatannol) by extracting similar bioactive compounds from coconut shell, achieving comparable or superior effectiveness through natural sources
