Multi-Chrome Hair Composition Using Interference Pigments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic hair compositions fail to achieve a true multichromatic appearance without causing hair damage, are expensive, or are environmentally harmful, as they either require permanent bleaching, offer single-hue temporary solutions, or use damaging microplastics in glitter sprays.
Innovation Solution
A cosmetic composition with a high hold base formula and interference pigments that provide a multichromatic effect, are removable with shampoo, and do not damage hair or the environment, featuring a base formula with a hair fixative and plasticizer to prevent flaking and enhance smoothness, along with fine interference particles for a chrome-like finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent bleaching and dye deposition is used to achieve multi-chrome appearance, then multichromatic effect is achieved, but hair damage becomes severe and process time increases to hours
Solution Approach 1:
The patent uses temporary cosmetic hair compositions that can be easily removed with shampoo, replacing permanent chemical treatments. The composition provides multichrome effect during use but leaves no permanent residue or damage, embodying the disposable principle where the cosmetic effect is temporary and non-damaging.
Solution Approach 2:
The patent employs interference pigments that create multichromatic effects through optical interference rather than permanent chemical dyeing. These pigments reflect different wavelengths of light at different angles, producing color changes without chemical alteration of the hair structure, thus avoiding damage while achieving the desired appearance.
2Object-affected harmful factors
If temporary hair color spray is used to avoid hair damage, then ease of removal is improved, but color coverage becomes too sheer for dark hair and single hue limits multichromatic effect
Solution Approach 1:
The patent combines multiple functional components including film-forming polymers, plasticizers, and interference pigments in a composite cosmetic composition. This composite formulation provides both adequate coverage on dark hair and true multichromatic effects, overcoming the limitations of simple temporary sprays while maintaining ease of removal.
Solution Approach 2:
The patent modifies the physical and chemical parameters of temporary cosmetic formulations by incorporating specific polymers and plasticizers that enhance film formation, opacity, and color intensity. These parameter changes enable the composition to provide sufficient coverage on dark hair while maintaining temporary nature and multichromatic capability.
3Strength
If high hold base formula is used to ensure firm attachment, then hold strength is improved, but flaking increases and smoothness decreases
Solution Approach 1:
The patent adjusts the physical parameters of the base formula by incorporating plasticizers that modify the rigidity and flexibility of the film-forming polymers. This parameter modification allows the composition to maintain strong hold while reducing flaking and improving smoothness, resolving the contradiction between hold strength and surface quality.
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 composition provides a smooth, full-coverage, multichromatic appearance that changes with the angle of observation, is easy to remove, and maintains hair health while being environmentally friendly.
Implementation Method 1
an interference pigment that provides a multichromatic effect to the hair when applied thereto
Implementation Method 2
fine interference particles capable of filling in the gaps of the hair shaft surfaces to create a smooth, chrome-like effect

AI summary
A multi-chrome cosmetic hair composition is disclosed. The composition includes a base formula suitable for hair and an interference pigment providing a colored background exhibiting interference colors that are observable at different angles of observation. The formula is sufficient to enable a homogenous suspension of the interference pigment. The formula includes a propellant, denatured alcohol, neutralized octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4, a neutralizing agent sufficient to neutralize the octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4 to a range of 80% to 100%, and a plasticizer. The interference pigment includes an opaque-type interference pigment consisting of particles ranging from 5 microns to 60 microns in size to fill in gaps on hair shaft surfaces and create a smooth, chrome-like effect on the hair. The interference pigment includes an inorganic layer that specularly reflects incident light and semi-transparent inorganic layers that refract the reflected light such that the interference colors are observable.
