Glycogen Purification for Cosmetic Velvet Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic uses of glycogen do not effectively achieve a velvet effect on the skin, which is characterized by softness and smoothness, and lack stability and ease of industrial manufacturing.
Innovation Solution
A cosmetic composition utilizing glycogen with low nitrogen and reducing sugars content, derived from natural sources such as molluscs or vertebrate animals, is formulated to provide a velvet effect, rapid absorption, lifting, and brightness to the skin, incorporating additives like Polglumyt™ glycogen, emulsifiers, hydrating agents, and preservatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glycogen is used in cosmetic formulations for skin application, then a velvet effect and lifting effect are achieved, but the presence of protein residues and reducing sugars compromises the quality and stability
Solution Approach 1:
The patent applies extraction by removing harmful components (protein residues and reducing sugars) from glycogen through purification processes. The method specifies obtaining glycogen with nitrogen content below certain thresholds and reducing sugars below specific levels, thereby isolating the beneficial velvet-effect-producing glycogen while eliminating quality-compromising impurities.
Solution Approach 2:
The patent applies parameter changes by defining specific quantitative thresholds for nitrogen content and reducing sugars content to ensure glycogen quality. By establishing precise parameter ranges (nitrogen content limits and reducing sugars concentration limits), the patent transforms the glycogen purification process into a controlled method that consistently produces high-quality cosmetic-grade glycogen.
2Reliability
If glycogen is used to achieve velvet effect, then skin softness and smoothness are improved, but the manufacturing complexity and quality control become more difficult
Solution Approach 1:
The patent simplifies manufacturing and quality control by establishing clear, quantifiable parameter thresholds for glycogen acceptance. By defining specific nitrogen content limits and reducing sugars concentration limits, the patent creates objective quality criteria that enable consistent manufacturing and straightforward quality assurance protocols.
Solution Approach 2:
The patent addresses manufacturing complexity by extracting and eliminating the variable factors (protein residues and reducing sugars) that complicate quality control. Through specified purification methods that remove these harmful components, the patent standardizes the glycogen product, making manufacturing and quality assurance more predictable and manageable.
3Adaptability or versatility
If commercial glycogen is used with varying protein residues and reducing sugars, then availability is maintained, but the quality and stability of cosmetic compositions are compromised
Solution Approach 1:
The patent resolves the conflict between availability and stability by establishing specific parameter thresholds that define acceptable glycogen quality. By specifying maximum nitrogen content and reducing sugars concentration, the patent creates a standardized product specification that ensures consistent quality and stability while maintaining broad availability through defined purification criteria.
Solution Approach 2:
The patent maintains availability while ensuring stability by extracting harmful components to defined levels. The purification methods specified remove protein residues and reducing sugars to predetermined thresholds, producing a standardized glycogen product that is both widely available and consistently stable across different batches and sources.
