Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Silicone polymers used in beauty and personal care products are difficult to wash off, contribute to environmental pollution due to slow biodegradation, and lack eco-friendly alternatives that maintain performance levels.
Innovation Solution
Recombinant silk polypeptides are used as replacements for silicone elastomers, providing similar benefits while being biodegradable and environmentally friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicone polymers are used in beauty and personal care products, then skin and hair benefits are achieved, but the products are difficult to wash off and contribute to environmental pollution
Solution Approach 1:
The patent changes the chemical composition parameters by replacing silicone-based polymers with recombinant silk polypeptides, maintaining the desired skin and hair benefits while fundamentally altering the material's biodegradability characteristics to eliminate environmental pollution
Solution Approach 2:
The invention adopts a biodegradable material that naturally decomposes after use, replacing the persistent silicone polymers. The recombinant silk polypeptide is designed to break down naturally in the environment, eliminating long-term pollution while maintaining product performance
2Reliability
If silicone elastomers are used to provide matte finish and long-lasting wear, then cosmetic performance is improved, but the silicone accumulates in pores and is hard to remove
Solution Approach 1:
The patent changes the chemical composition from hydrophobic silicone elastomers to recombinant silk polypeptides with different surface properties, maintaining the film-forming and wear-resistant characteristics while improving washability through natural biodegradability and compatibility with cleansing agents
3Object-generated harmful factors
If biobased alternatives are used to replace cyclosiloxane diluent, then eco-friendliness is improved, but the silicone elastomer remains non-biodegradable
Solution Approach 1:
The invention completely replaces the non-biodegradable silicone elastomer with a biodegradable recombinant silk polypeptide, ensuring the entire product decomposes naturally after use, eliminating persistent environmental accumulation
Solution Approach 2:
The patent creates a composite material system using recombinant silk polypeptides that combines the desirable properties of silicone elastomers (film-forming, matte finish, wear resistance) with biodegradability, achieving both performance and environmental sustainability
