Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hyaluronic acid cosmetics struggle to penetrate the stratum corneum, leading to short-term moisturizing effects and the need for frequent application to improve skin wrinkles.
Innovation Solution
A hyaluronate skin-penetrating cosmetic comprising a hyaluronate and an amphoteric surfactant, which facilitates penetration without the need for complex nanoparticulation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If hyaluronic acid component is simply applied to the skin, then the moisturizing effect remains on the surface of the skin, but only a short-term moisturizing effect can be exerted
Solution Approach 1:
The patent changes the chemical parameters of the hyaluronate by converting it to a salt form (such as sodium hyaluronate, potassium hyaluronate, or ammonium hyaluronate) and controlling the molecular weight to 1,000,000 or less. This parameter transformation enables the hyaluronate to penetrate the stratum corneum effectively while maintaining moisturizing properties, thus extending the duration of action from short-term surface effect to long-term deep skin effect.
2Manufacturing precision
If nanoparticulation of hyaluronic acid is performed by supporting on support material, then penetration capability is improved, but complicated steps such as ultracentrifugation are required for production
Solution Approach 1:
The patent extracts and eliminates the complex nanoparticulation process and support materials from the formulation. Instead of using polylactic acid nanoparticles or zwitterionic compound complexes that require ultracentrifugation, the invention uses simple hyaluronate salts that can be directly applied to the skin, thereby removing the complicated production steps while maintaining effective skin penetration.
Solution Approach 2:
The patent replaces complex, expensive nanoparticulation systems with simple, inexpensive hyaluronate salt formulations. These simple formulations achieve their purpose effectively without requiring sophisticated manufacturing equipment or multiple processing steps, making the production process more economical and accessible.
3Manufacturing precision
If composite formation of hyaluronic acid component is performed, then penetration capability is improved, but complicated steps are required for production
Solution Approach 1:
The patent removes the need for composite formation processes entirely. Instead of creating complexes with zwitterionic compounds or other materials that require sophisticated manufacturing, the invention uses pure hyaluronate salts that can be manufactured through simple, straightforward processes, greatly improving ease of manufacture while maintaining penetration effectiveness.
