Method for forming coating on skin surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic nanofiber sheets face issues with holding a large amount of cosmetic components, adhesion to the skin, and maintaining transparency, especially when containing colored pigments, as they tend to deteriorate and do not form a transparent coating that enhances skin color.
Innovation Solution
A method involving the application of a sheet transparentizing agent containing 2% or more oil agents to the skin, followed by transferring a white nanofiber sheet composed of a water-insoluble polymer, which improves adhesivity and maintains transparency by ensuring the nanofiber sheet adheres well and remains transparent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a nanofiber sheet containing colored pigment is applied to the skin, then the cosmetic effect is enhanced, but the transparency of the coating deteriorates and the sheet does not adhere well to the skin
Solution Approach 1:
The patent applies a sheet transparentizing agent containing oil agents to the skin before transferring the nanofiber sheet. This preliminary action creates an oily layer on the skin surface that enables the water-insoluble polymer in the nanofiber sheet to adhere effectively, solving the adhesion problem without compromising the cosmetic components or transparency
Solution Approach 2:
The sheet transparentizing agent acts as an intermediary substance between the skin and the nanofiber sheet. It contains oil agents that bridge the incompatibility between the water-insoluble polymer in the nanofiber sheet and the skin surface, enabling adhesion while maintaining the sheet's transparency and cosmetic properties
2Quantity of substance
If a nanofiber sheet containing colored pigment is applied to the skin, then the cosmetic effect is enhanced, but the transparency of the coating deteriorates
Solution Approach 1:
The transparentizing agent is applied to the skin before the nanofiber sheet, creating an optimized surface that allows the sheet to become transparent upon adhesion. This preliminary preparation ensures that the final coating achieves both cosmetic enhancement and transparency
Solution Approach 2:
The patent changes the surface parameters of the skin by applying an oil-containing agent, which alters the optical and adhesive properties of the skin surface. This parameter change enables the nanofiber sheet to achieve transparency and proper adhesion simultaneously
3Stability of the object's composition
If a nanofiber sheet with water-insoluble polymer is used, then the sheet structure is stable, but the adhesion to skin deteriorates
Solution Approach 1:
The sheet transparentizing agent containing oil agents serves as a mediator between the water-insoluble polymer and the skin. The oil components in the agent are compatible with both the hydrophobic polymer and the skin surface, enabling adhesion without compromising the structural stability of the water-insoluble polymer sheet
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 method significantly enhances the adhesivity and transparency of the nanofiber coating, allowing the skin to be visible while maintaining the coating's transparency and adhesion over time.
Implementation Method 1
transferring a white nanofiber sheet mainly composed of a water-insoluble polymer to the skin after Step (1)... remarkably improving the adhesivity to the skin
Implementation Method 2
the adhered nanofiber sheet becomes transparent, thereby remarkably improving the adhesivity to the skin, to complete the present invention
