Sunscreen UV Filter Composition for Skin Microbiome Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to protect beneficial skin bacteria, such as Lactobacillus crispatus and Staphylococcus epidermidis, from the detrimental effects of UV radiation, as UV-light can destroy these microbes.
Innovation Solution
The use of UV filters like octocrylene, butyl methoxydibenzoylmethane, and ethylhexyl triazone is employed to enhance the survival rate of these bacteria by increasing their resistance to UV radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UV filters are applied to protect skin bacteria from UV radiation, then the survival rate of beneficial bacteria increases, but the complexity of the sunscreen composition increases
Solution Approach 1:
The patent applies UV filters that serve dual functions: protecting human skin from UV damage while simultaneously protecting beneficial skin bacteria (Lactobacillus and Staphylococcus epidermidis) from UV radiation. This multi-functionality resolves the contradiction by achieving bacterial protection without requiring separate specialized components
Solution Approach 2:
The patent optimizes the concentration parameters of specific UV filters (octocrylene at 0.1-5%, ethyl hexyl triazone at 0.1-5%, butyl methoxydibenzoylmethane at 0.1-5%) to achieve effective bacterial protection while maintaining formulation simplicity. By precisely controlling these parameters, the patent resolves the contradiction between effectiveness and complexity
2Object-affected harmful factors
If conventional UV filters are used, then skin protection from UV radiation is achieved, but beneficial skin bacteria are destroyed
Solution Approach 1:
The patent creates different microenvironments within the sunscreen formulation by selecting UV filters with specific spectral absorption characteristics. These filters create localized protection zones that selectively allow certain wavelengths to pass through while blocking harmful UV radiation, thereby protecting bacteria in specific microenvironments within the skin microbiome
Solution Approach 2:
The UV filters act as intermediary substances that mediate between UV radiation and biological entities. Specifically, octocrylene, ethyl hexyl triazone, and butyl methoxydibenzoylmethane serve as mediators that absorb UV energy and convert it to harmless forms, protecting both human skin and beneficial bacteria without requiring direct contact between UV radiation and bacterial cells
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The survival rate of Lactobacillus crispatus is increased by at least 100% and Staphylococcus epidermidis by at least 20% after UV exposure, indicating effective protection against UV radiation.
Implementation Method 1
certain UV-filter substances are particularly suitable to protect bacteria of the genus Lactobacillus such as in particular L. crispatus as well as S. epidermidis against the detrimental effects of UV-radiation
