Solution Overview
Problem
There is a need for new liquid polymer materials in cosmetic compositions that can be easily produced, modified, and derived from safe and sustainable raw materials, offering improved stability, storability, and specific functional properties for skin and hair care applications.
Innovation Solution
The development of personal care compositions using polyether polymers derived from naturally occurring monomers like citronellol, prenol, isocitronellol, and isoprenol, which can be polymerized and functionalized to provide a range of desirable properties such as emulsifiers, preservatives, and UV protection agents, replacing traditional silicone polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional silicone polymers are used in cosmetic compositions, then functional properties such as emulsification and protection are achieved, but the compositions lack sustainability and environmental friendliness
Solution Approach 1:
The patent changes the chemical composition parameters by replacing silicone-based polymers with polyether polymers derived from renewable monomers (citronellol, prenol, isocitronellol, isoprenol). This substitution maintains the functional properties (emulsification, protection, stability) while improving environmental sustainability and biodegradability, directly resolving the contradiction between reliability and environmental harm.
Solution Approach 2:
The patent employs biodegradable polyether polymers that can be naturally decomposed, replacing persistent silicone polymers. These polyether polymers derive from renewable resources and offer comparable functional performance with reduced environmental persistence, effectively applying the principle of using materials that can be safely replaced by nature.
2Object-affected harmful factors
If new polyether polymers are developed from natural monomers, then sustainability and environmental friendliness are improved, but production complexity and derivatization requirements increase
Solution Approach 1:
The patent develops polyether polymers with multiple functional groups (hydroxyl, carboxyl, amino groups) that can serve various purposes in cosmetic formulations. This multi-functionality allows a single polymer platform to provide emulsification, stabilization, and active ingredient delivery, simplifying the overall formulation process despite the natural monomer origin.
Solution Approach 2:
The patent employs modular polymer architecture where polyether backbones are functionalized with different side chains and terminal groups. This segmentation allows independent optimization of each functional component while maintaining a standardized polymer synthesis platform, thereby managing production complexity through systematic modularity.
3Adaptability or versatility
If polyether polymers are functionalized to modify properties, then specific functional properties are enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The patent systematically varies polymer parameters including molecular weight, degree of polymerization, and functional group types to achieve desired properties. By establishing controlled synthesis methods that allow precise parameter adjustment, the patent enhances adaptability while managing manufacturing complexity through standardized process variables.
Solution Approach 2:
The patent creates composite polyether structures by combining different monomer units and functional groups within a single polymer chain. This composite approach allows multiple functions to be integrated into one material system, reducing the need for separate additives and simplifying the overall manufacturing process despite the enhanced functionality.
