Rare Earth Keratin Coating for Wash-Resistant Cosmetic Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic treatments for keratin materials, such as hair and skin, provide temporary cosmetic effects that require frequent reapplication, failing to maintain shape or optical effects through washing or rinsing.
Innovation Solution
A two-step method involving the application of a rare earth metal compound followed by an alkaline composition to create a durable inorganic coating on keratin materials, enhancing cosmetic performance and resistance to washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traditional styling products (lacquer or spray) are used to fix hair shape, then the hairstyle can be retained for a few hours to a day, but the effect is not lasting and requires daily reapplication and washing
Solution Approach 1:
The rare earth metal compound is applied to the hair in advance and penetrates the hair structure before styling. This preliminary action creates a permanent mold within the hair that maintains the styled shape indefinitely, eliminating the need for daily reapplication of styling products.
Solution Approach 2:
The invention combines rare earth metal compounds with alkaline compositions to create a composite treatment system. The rare earth metal penetrates and bonds within the hair structure, while the alkaline composition facilitates this bonding, together creating a durable permanent styling effect that resists washing.
2Duration of action of stationary object
If traditional cosmetic products are applied to skin for optical effects or blemish concealment, then the cosmetic effect is achieved, but the hold is limited and requires reapplication multiple times during the day
Solution Approach 1:
The rare earth metal compound is applied to the skin in advance and penetrates the skin structure to create a permanent mold. This preliminary action ensures that the cosmetic effect lasts through multiple washings without requiring reapplication, significantly improving ease of operation.
3Shape
If styling products are used to maintain hair shape, then the desired shape can be achieved, but the products require washing and reapplication daily
Solution Approach 1:
The rare earth metal compound penetrates the hair structure in advance and creates a permanent mold that maintains the styled shape. This preliminary structural modification ensures the hairstyle shape is reliable and resistant to washing operations, eliminating the need for daily reapplication.
4Illumination intensity
If makeup products are applied to skin for cosmetic effects, then the optical effect or blemish concealment is achieved, but the effect is temporary and requires frequent reapplication
Solution Approach 1:
The rare earth metal compound penetrates the skin structure in advance and creates a permanent mold that maintains cosmetic effects. This preliminary action ensures that optical effects and blemish concealment last through multiple washings, significantly extending duration compared to traditional makeup products.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
