Thermal-Stable Hair Styling Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal styling sprays for hair styling under heat conditions release toxicologically non-harmless substances and cause unpleasant odors when heated, posing health risks to users, especially professionals in the salon industry.
Innovation Solution
A cosmetic composition comprising ingredients that are stable up to 200°C against thermal decomposition, including protein hydrolyzates, cationic and non-ionic polymers, surfactants, and specific aromas like 2-phenylethyl alcohol, which do not decompose and release harmful gases at high temperatures, ensuring safety and reduced odor formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thermal styling sprays are used for hair styling under heat treatment, then styling performance is achieved, but toxicologically harmful substances are released and unpleasant odors are generated
Solution Approach 1:
The patent changes the chemical composition parameters of the styling spray by selecting ingredients with high thermal stability (decomposition temperature >200°C). This parameter change ensures that the spray maintains its styling performance while avoiding the release of harmful substances and odors during heat treatment at temperatures up to 200°C.
Solution Approach 2:
The patent uses a composite formulation containing multiple temperature-stable ingredients including polymers, surfactants, and conditioning agents. This composite material approach allows the spray to deliver comprehensive styling performance while all components remain stable and non-harmful under thermal conditions.
2Object-affected harmful factors
If ingredients stable up to 200°C are used in the composition, then health safety and reduced odor formation are achieved, but formulation complexity increases
Solution Approach 1:
The patent employs multi-functional ingredients that simultaneously provide thermal stability, styling performance, and conditioning benefits. For example, certain polymers and surfactants serve multiple purposes: they maintain spray performance, provide heat resistance, and ensure ingredient stability, thereby reducing the need for additional specialized components.
3Device complexity
If conventional styling ingredients are used, then formulation simplicity is maintained, but decomposition and harmful gas release occur at high temperatures
Solution Approach 1:
The patent applies parameter changes by selecting ingredients whose decomposition temperature exceeds 200°C. This fundamental parameter change in ingredient selection prevents decomposition and harmful gas release during hot iron styling, while maintaining relatively simple formulation structures.
