Bile Acid Sunscreen Molecule Broad Spectrum Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreen compositions face challenges in providing broad-spectrum UV protection while maintaining stability, as organic UV-A and UV-B sunscreens often require high concentrations, leading to instability and safety issues, and inorganic sunscreens cause unnatural skin discoloration.
Innovation Solution
A novel sunscreen molecule is developed by attaching UV-A and UV-B sunscreens to a bile acid backbone, specifically cholic acid, to create a stable and broad-spectrum photoprotective agent that combines the efficacy of both without the stability issues of individual organic sunscreens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inorganic sunscreens are used to block solar radiation, then UV protection is provided, but unnatural whiteness appears on the skin
Solution Approach 1:
The patent merges UV-A and UV-B sunscreen moieties into a single molecular entity attached to a bile acid backbone, creating a unified broad-spectrum sunscreen agent that provides both UV protections without the discoloration issues of inorganic sunscreens
Solution Approach 2:
The invention creates a composite molecular structure combining organic UV-A and UV-B sunscreen components with a bile acid backbone, forming a new class of broad-spectrum sunscreen agents that achieve superior UV protection with natural skin appearance
2Adaptability or versatility
If both UV-A and UV-B sunscreens are included in composition to achieve broad spectrum protection, then wide wavelength coverage is obtained, but composition cost increases and stability decreases
Solution Approach 1:
The patent combines UV-A and UV-B sunscreen moieties into a single molecular structure where both protective functions are integrated, eliminating the need for separate UV-A and UV-B sunscreen components and their associated stability compatibility issues
Solution Approach 2:
The bile acid-based sunscreen molecule performs multiple functions simultaneously - it provides both UV-A and UV-B protection, achieves broad spectrum coverage, and maintains enhanced stability, making a single agent replace multiple separate sunscreen components
3Reliability
If organic UV-A sunscreen is used at high concentration to improve protection, then UV-A coverage is enhanced, but safety and stability issues arise
Solution Approach 1:
The patent integrates UV-A protection capability into a unified molecular structure with UV-B protection, achieving effective UV-A coverage without requiring high concentrations of separate UV-A sunscreen components that cause safety and stability problems
