BEMT UV Filter Antioxidant Photostability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun care compositions struggle with achieving high levels of UV protection while maintaining a stabilized and pleasant texture, and they often lack effective antioxidant stability against light, which is particularly problematic for skin protection against UVA rays.
Innovation Solution
The composition includes bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) in combination with an antioxidant system, where BEMT is added to improve the photostability of the antioxidant system, thereby enhancing both UV protection and antioxidant stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high levels of UV filters are used to achieve high UV protection, then UV protection efficiency is improved, but composition texture stability and pleasantness deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the UV filter system by introducing BEMT (2,4-bis-{[4-(2-ethyl hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine) as a key component. This specific chemical compound provides high UV protection while maintaining composition stability, resolving the contradiction between protection efficiency and texture stability.
Solution Approach 2:
The patent creates a composite antioxidant system comprising multiple components (BEMT, vitamin C, vitamin E, ferulic acid) that work synergistically. This composite approach achieves both high UV protection and maintained composition stability, as the combination of ingredients provides complementary protection and stabilizing effects.
2Reliability
If antioxidants are added to neutralize free radicals and ROS, then antioxidant activity is improved, but photostability of the antioxidant system deteriorates
Solution Approach 1:
BEMT acts as an intermediary photostabilizer within the antioxidant system. It absorbs UV radiation and prevents the degradation of other antioxidant components (vitamin C, vitamin E, ferulic acid), thereby maintaining the photostability of the entire antioxidant system while preserving its neutralizing activity.
Solution Approach 2:
The patent develops a composite antioxidant system where BEMT works in conjunction with vitamin C, vitamin E, and ferulic acid. This composite formulation provides both high antioxidant activity and improved photostability, as each component contributes different functions that complement each other.
3Reliability
If multiple sunscreens and UV filters are combined to achieve high protection levels, then UV protection efficiency is improved, but device complexity and formulation difficulty increase
Solution Approach 1:
BEMT serves multiple functions simultaneously: it provides high UV protection, acts as a photostabilizer, and enhances the stability of other antioxidant components. This multi-functionality reduces the need for multiple separate ingredients, simplifying the formulation while maintaining high protection levels.
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 use of BEMT in the composition significantly improves the photostability of the antioxidant system, ensuring effective UV protection and antioxidant activity even after exposure to light, thus providing better skin protection against photoaging.
Implementation Method 1
radiation of wavelengths between 290 nm and 400 nm allows tanning of the human epidermis... UVA rays with wavelengths between 320 and 400 nm penetrate deeper into the skin
Implementation Method 2
add antioxidants to products designed to be applied to keratinous material, particularly the skin, for their ability to neutralize free radicals and Reactive Oxygen Species (ROS) generated under Oxidative Stress
