Solution Overview
Problem
Existing hair coloring technologies cause temporary scalp irritation, alter hair structure, result in unpredictable and uneven color, and have poor color retention due to oxidation-based methods, leading to undesirable hair condition and aesthetic issues.
Innovation Solution
A multicomponent composition comprising an organic polymer, an in situ linking material, and a base compound, which forms a wash-resistant coating with pigment microparticles, providing uniform color and long-lasting results while minimizing damage to hair proteins, and can be easily removed with a trigger formulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If oxidation-based dyeing methods are used to achieve hair coloration, then color can be deposited on hair, but scalp irritation occurs and hair structure is altered
Solution Approach 1:
The patent introduces a film-forming polymer composition as an intermediary carrier that deposits pigment particles on hair without requiring oxidation. This intermediary system allows color deposition while avoiding the harmful effects of traditional oxidative dyes on scalp and hair structure
Solution Approach 2:
The invention changes the chemical parameters of the coloring system by replacing oxidation-based chemistry with a film-forming polymer system that cures through different mechanisms (e.g., moisture curing or UV curing), thereby eliminating the harmful oxidative effects while maintaining color deposition capability
2Quantity of substance
If traditional pigment-based coloring approaches are used, then color can be applied to hair, but color retention is poor and color is removed after a few washings
Solution Approach 1:
The patent creates a composite material system combining pigment particles dispersed in a film-forming polymer matrix. This composite structure ensures that pigments are embedded within the polymer film rather than merely sitting on the hair surface, providing durable color retention that withstands multiple washings
Solution Approach 2:
The film-forming polymer creates a continuous coating layer (film) over the hair surface that encapsulates the pigment particles. This film structure provides a protective barrier that prevents pigment removal during washing, thereby improving color retention
3Quantity of substance
If dye-based coloring materials are applied to achieve coloration, then hair color can be changed, but results are uneven and difficult to predict
Solution Approach 1:
The patent uses a homogenous film-forming polymer composition that provides uniform coverage across the hair surface. The polymer matrix ensures consistent distribution and adhesion of pigment particles, resulting in uniform and predictable coloration that is independent of variations in underlying hair structure or porosity
4Ease of operation
If water-soluble film formers are used in pigment-based coloring, then application is easy, but color adherent fastness is low and color is easily removed
Solution Approach 1:
The patent changes the solubility parameter of the film-forming polymer from water-soluble to water-insoluble or water-resistant. This parameter change allows the polymer to form a durable, adherent film on hair that resists washing, thereby improving color fastness while maintaining ease of application during the wet state
