Oat Bran Polysaccharides for Immediate Skin Tensor Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic active ingredients for addressing skin aging, such as synthetic polymers and proteins, are difficult to formulate and do not effectively provide an immediate anti-wrinkle and tensor effect on the skin.
Innovation Solution
The method involves extracting and purifying high molecular weight polysaccharides from oat bran, specifically alpha-glucans with a molecular weight of 25 kDa to 300 kDa, and stabilizing them in water to create a polysaccharide-rich active ingredient that improves skin viscoelastic properties and provides an immediate tensor effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic polymers are used for skin lifting, then lifting effect is achieved, but formulation difficulty increases due to solubility issues
Solution Approach 1:
The patent changes the chemical nature of the polymer from synthetic to natural plant-based polysaccharides, which fundamentally alters solubility parameters. Plant polymers are naturally water-soluble unlike synthetic polymers that require alcohol, thereby resolving the formulation difficulty while maintaining the lifting effect through comparable viscoelastic properties
Solution Approach 2:
The patent uses readily available plant-based materials (corn, potato, oat, rice, wheat, barley) as substitutes for expensive synthetic polymers. These natural polymers can be obtained from common agricultural byproducts, making the formulation process simpler and more accessible while achieving the desired cosmetic effect
2Reliability
If proteins are used for skin lifting, then lifting effect is achieved, but the desired immediate tensor effect is not obtained
Solution Approach 1:
The patent changes the molecular weight parameter of the polysaccharides to be in the range of 10,000 to 1,000,000 Dalers, which is higher than typical protein-based solutions. This high molecular weight configuration enables the polysaccharides to form a more effective viscoelastic network that provides the desired immediate tensor and lifting effects on the skin
Solution Approach 2:
The patent creates a composite active ingredient that combines multiple plant-derived polysaccharides with specific molecular weight characteristics. This composite approach leverages the viscoelastic properties of natural polymers to achieve tensor effects that are more immediate and effective compared to protein-based alternatives
3Ease of manufacture
If plant polymers are used, then formulation ease improves, but molecular weight control becomes challenging
Solution Approach 1:
The patent establishes specific molecular weight ranges (10,000 to 1,000,000 Dalers, preferably 50,000 to 500,000 Dalers) as critical parameters for achieving the desired cosmetic effect. By defining these precise ranges, the patent provides guidance for controlling polymerization degree during extraction and processing, ensuring consistent performance while maintaining the formulation simplicity of plant-based materials
