Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunscreen products with organic UV-filters face challenges in achieving improved SPF performance and UVA photoprotection, often leading to skin irritations and environmental concerns, while limited UVA-filters restrict broad-spectrum protection.
Innovation Solution
Incorporating mycosporine-like amino acid compounds, represented by specific formulas, into sunscreen products to enhance SPF and UVA photoprotection, providing broad-spectrum protection and anti-aging benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If organic UV-filters are used to achieve broad-spectrum protection, then SPF performance and UVA photoprotection are improved, but skin irritations and environmental concerns increase
Solution Approach 1:
The patent extracts the harmful aspects of organic UV-filters by replacing them with inorganic UV-filter particles (such as zinc oxide or titanium dioxide) that provide similar or superior UV protection without the associated skin irritation and environmental harm. This extraction of the harmful component while maintaining the protective function directly resolves the contradiction between achieving good SPF performance and avoiding harmful effects.
Solution Approach 2:
The patent changes the fundamental parameter of the UV-filter material from organic compounds to inorganic particles, altering the chemical composition and physical properties. This parameter change enables the maintenance of high SPF and UVA protection levels while eliminating the harmful effects associated with organic filters, as the inorganic particles work through physical blocking and scattering mechanisms rather than chemical absorption that causes irritation.
2Adaptability or versatility
If limited UVA-filters are used, then formulation complexity is reduced, but broad-spectrum protection is insufficient
Solution Approach 1:
The patent employs inorganic UV-filter particles that serve multiple functions simultaneously: they provide broad-spectrum UV protection (both UVA and UVB), offer physical blocking mechanism, and eliminate the need for multiple different organic filter compounds. This multi-functionality achieves comprehensive broad-spectrum protection while simplifying the overall formulation, as a single inorganic filter system can replace what would traditionally require several organic UV-filter ingredients.
