Electrospun Cosmetic Membrane Packaging for Active Ingredient Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic products face challenges such as difficulty in application, residue left on skin or applicators, unsuitable transport and release of active ingredients, and compounds that are functional for formulation structure but not beneficial for the skin, potentially causing drying or sensitization.
Innovation Solution
A method and apparatus for producing a cosmetic patch product using electrospinning to create a biocompatible membrane substrate, which is then packaged with a coating film to form a hermetically sealed wrapping, allowing high concentrations of active ingredients like hyaluronic acid and maintaining product integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cosmetic formulations (creams, lotions, serums) are applied to the skin, then functional compounds can be delivered to the skin, but the products are difficult to apply, require prolonged application times, leave residues on skin or applicators, and do not allow complete absorption into the dermis
Solution Approach 1:
The patent employs a fibrous physical support in the form of a thin film or wipe that can be easily applied to the skin. This flexible film structure allows for simple, quick application without requiring prolonged massage or rubbing, directly resolving the contradiction between ease of application and application time.
Solution Approach 2:
The invention extracts the cosmetic composition from traditional difficult-to-apply formulations and transfers it onto a fibrous physical support. This separation allows the active ingredients to be delivered via the wipe structure, eliminating the need for prolonged manual application and improving ease of use.
2Ease of operation
If a fibrous physical support is used to apply cosmetic products, then application is facilitated, but the support and packaging must be disposed of after use, creating waste
Solution Approach 1:
The fibrous physical support is designed to serve multiple functions: it acts as both the application tool and the cosmetic composition itself. By making the support functional (imbued with active ingredients like hyaluronic acid), it eliminates the need for separate packaging and reduces waste, as the entire wipe can be applied to the skin and absorbed or discarded without additional packaging material.
3Ease of operation
If known fibrous physical supports are used, then application is simplified, but the specific surface does not allow suitable transport and release of active ingredients
Solution Approach 1:
The patent specifies that the fibrous physical support has a porous structure with appropriate specific surface area that enables effective transport and release of active ingredients. The porous nature of the fibrous material allows the cosmetic composition to be carried through the wipe and released onto the skin, resolving the contradiction between ease of application and reliability of ingredient delivery.
4Stability of the object's composition
If compounds functional for formulation structure (silicones, petrolatums, alcohols, preservatives) are used to give consistency and stability, then the formulation structure is improved, but these compounds do not bring benefit to the skin and can cause drying, pore closure, or sensitization
Solution Approach 1:
The invention extracts and eliminates harmful structural compounds (silicones, petrolatums, alcohols, preservatives) from the cosmetic formulation. By formulating the cosmetic composition without these problematic ingredients and delivering it via a fibrous wipe, the patent maintains formulation stability through the wipe structure itself while removing skin-damaging substances, thus resolving the contradiction between formulation stability and skin safety.
Solution Approach 2:
The patent changes the formulation parameters by eliminating traditional stabilizing and structuring agents that harm the skin. Instead, it uses a fibrous physical support with specific structural properties (porosity, surface area, fiber composition) to provide the necessary formulation stability and delivery mechanism, thereby achieving stability without harmful compounds.
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 solution enables efficient, industrial-scale production of a packaged cosmetic product that maintains active ingredient efficacy while preventing skin drying and sensitization, with high concentrations of beneficial compounds like hyaluronic acid.
