Removable Hair Coloring Composition Using Natural Oil Solubility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair coloring products for temporary coverage of grey hair are inconvenient, as they are not sweat-resistant, often smudge, require frequent reapplication, and use harsh chemicals for removal, posing challenges for active individuals and those seeking a natural solution.
Innovation Solution
Development of removable hair coloring compositions comprising a hair color component and a sealing component that can be physically dissolved or removed with natural oils, allowing for easy application and natural removal without harsh chemicals, suitable for various hair types and applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If temporary hair color products are used for grey hair coverage, then the application is simple and inexpensive, but the color is not sweat-resistant and requires frequent reapplication
Solution Approach 1:
The patent uses a composite material system consisting of natural oil-soluble colorants combined with sealing waxes and natural oils. This composite formulation allows the color to be locked in place while remaining removable with natural oils, achieving both reliability during wear and ease of removal afterward.
Solution Approach 2:
The patent changes the chemical parameter of the colorant to be oil-soluble rather than water-soluble. This parameter change enables the color to resist water and sweat while allowing removal with natural oils, resolving the contradiction between durability and removability.
2Duration of action of stationary object
If permanent hair color is used for grey hair coverage, then the coverage is long-lasting, but the product contains harsh chemicals and damages hair
Solution Approach 1:
The patent employs temporary colorants that are designed to be removed after a single wear period. These natural oil-soluble colorants provide long-lasting coverage during the wear period but can be completely removed with natural oils, avoiding the cumulative damage of permanent chemicals while maintaining long-term usability through repeated applications.
Solution Approach 2:
The patent introduces natural oils as an intermediary substance that enables removal of the colorant without harsh chemicals. The oil-soluble colorants are specifically designed to bind to hair and resist water, but dissolve in natural oils, providing a gentle removal mechanism that avoids chemical damage.
3Ease of operation
If temporary hair color products are used, then the product is easily removed with shampoo, but the color runs with sweat and smudges on hands and clothing
Solution Approach 1:
The patent changes the solubility parameter of the colorant from water-soluble to oil-soluble. This parameter change fundamentally alters the behavior of the color: it becomes resistant to water and sweat (preventing running and smudging) while remaining soluble in natural oils (enabling easy removal).
Solution Approach 2:
The patent uses sealing waxes and natural oils as intermediary substances that create a protective barrier around the colorant. This barrier prevents the color from migrating with sweat or transferring to hands and clothing, while still allowing controlled removal with natural oils.
4Reliability
If frequent reapplication of temporary color is required, then the initial coverage can be maintained, but the time and maintenance effort increase significantly
Solution Approach 1:
The patent creates a composite system where sealing waxes and natural oils work together to lock in the colorant. This composite structure provides enhanced durability and sweat resistance, reducing the frequency of reapplication while maintaining reliable coverage throughout the wear period.
