Solvent-Free Grape Extract for Skin Antioxidant Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Skin aging is primarily driven by oxidative mechanisms, leading to the degradation of collagen and elastin, resulting in wrinkles and loss of skin elasticity, for which existing cosmetic products lack effective solutions to harness the antioxidant benefits of polyphenols from specific grape varieties.
Innovation Solution
Development of Tannat or Cannonau grape extracts, presented in oily or aqueous forms, rich in polyphenols, vitamins, and trace elements, extracted using a solvent-free process involving thermal and mechanical treatments, to create a composition that can be used in cosmetics, dermatology, and food applications, maximizing antioxidant power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods using solvents are used, then extraction efficiency is improved, but residual solvents contaminate the product and reduce safety
Solution Approach 1:
The patent extracts polyphenolic active ingredients from grape seeds using a physical extraction method with water and heat, eliminating the need for organic solvents. This resolves the contradiction by achieving effective extraction while removing harmful solvent residues that would contaminate the cosmetic product.
Solution Approach 2:
The extraction process is conducted in an inert or oxygen-free atmosphere to prevent oxidation of the extracted polyphenols and to eliminate the need for organic solvents. This approach maintains extraction efficiency while ensuring product safety by avoiding solvent contamination.
2Reliability
If high concentrations of polyphenols are extracted, then antioxidant power is improved, but oxidation of the extract during storage increases
Solution Approach 1:
The patent performs extraction in an inert or oxygen-free atmosphere before the product is finalized. This preliminary action prevents oxidation from occurring during the extraction process itself, allowing high polyphenol concentrations to be achieved while maintaining oxidative stability throughout storage.
Solution Approach 2:
By conducting the extraction and initial processing in an inert or oxygen-free atmosphere, the patent protects the high-concentration polyphenol extract from oxidation. This resolves the contradiction by maintaining both high antioxidant power and long-term oxidative stability.
3Reliability
If polyphenolic extracts are added to cosmetic products, then antioxidant protection is improved, but formulation complexity increases
Solution Approach 1:
The patent creates a universal polyphenolic extract that can be directly incorporated into various cosmetic formulations without requiring additional processing or complex stabilization steps. The extract serves multiple functions (antioxidant, skin protection) while maintaining simplicity in formulation integration, resolving the contradiction between effectiveness and complexity.
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 composition exhibits a synergistic antioxidant effect, significantly delaying skin aging by enhancing collagen synthesis and protecting against oxidative stress, as demonstrated by increased ORAC values and improved skin health indicators.
Implementation Method 1
physical extraction of the lipophilic non-volatile active ingredients from the grape grains to said oil by a process involving only thermal and mechanical treatments
Implementation Method 2
physical extraction of the lipophilic non-volatile active ingredients from the grape grains to said oil by a process involving only thermal and mechanical treatments
Implementation Method 3
The phenomena of chemical oxidation (oxidation in which light radiation also intervenes) and enzymatic oxidation increase with age. These mechanisms lead to the densification of the collagen network, the degradation of elastins
Implementation Method 4
In the skin, free radicals attack cell membranes by degrading collagen, an essential element involved in the appearance of wrinkles. Increasingly, cosmetic product manufacturers are introducing anti-free radical active ingredients, including polyphenols, into their creams.
