Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oxidative hair treatment agents, commonly used for coloring and lightening hair, cause damage to the hair structure and surface, leading to brittleness, reduced elasticity, and increased sensitivity, necessitating additional conditioning treatments, and are often unstable under oxidative conditions.
Innovation Solution
A two-phase cosmetic preparation comprising an aqueous phase with a chemical oxidizing agent, such as hydrogen peroxide, and a hydrophobic phase with silicone oil, which are immiscible and separated, to minimize damage and provide care properties, stabilizing oxidatively unstable care substances and reducing the need for additional treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If oxidative hair treatment agents are used for coloring and lightening hair, then color-changing and lightening effects are achieved, but hair structure and surface are damaged
Solution Approach 1:
The preparation is divided into two separate phases: an aqueous phase containing the oxidizing agent and a hydrophobic phase containing care substances. This segmentation allows the oxidizing agent to perform its color-changing function while the care substances in the hydrophobic phase protect the hair, resolving the contradiction between achieving color effects and preventing hair damage.
Solution Approach 2:
The hydrophobic phase acts as an intermediary that delivers care substances to the hair during the oxidative treatment process. This intermediary phase protects the hair structure from oxidative damage while allowing the oxidizing agent in the aqueous phase to perform its color-changing function.
2Ease of manufacture
If oxidative hair treatment agents are used, then color and lightening effects are achieved, but additional conditioning treatments are required
Solution Approach 1:
The invention merges the color-changing function (oxidizing agent in aqueous phase) and the care function (substances in hydrophobic phase) into a single preparation. This combination eliminates the need for separate conditioning treatments, simplifying the overall treatment process while maintaining both color-changing efficacy and hair care benefits.
Solution Approach 2:
The two-phase preparation serves multiple functions simultaneously: the aqueous phase provides oxidizing action for color change, while the hydrophobic phase provides care and protection. This multi-functionality in a single product reduces the complexity of requiring multiple separate treatments.
3Object-affected harmful factors
If care substances are added to oxidative hair treatment agents, then hair protection is improved, but stability under oxidative conditions deteriorates
Solution Approach 1:
By segmenting the preparation into two phases, care substances are isolated in the hydrophobic phase away from the oxidizing agent in the aqueous phase. This physical separation maintains the stability of care substances under oxidative conditions while still allowing them to provide protection to the hair during treatment.
Solution Approach 2:
The hydrophobic phase serves as a protective intermediary that shields care substances from direct exposure to the oxidizing environment. This intermediary phase allows care substances to remain stable while still enabling them to interact with and protect the hair structure.
