Triazine UV Absorber Composition for Broad-Spectrum Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreen cosmetic compositions fail to provide comprehensive protection against both short (UV-B and UV-C) and long (UV-A) wavelength ultraviolet rays, often requiring high concentrations of organic sunscreen agents that can cause physiological damage, and inorganic substances like titanium dioxide may not offer adequate protection across the entire UV spectrum without skin whitening effects.
Innovation Solution
A sunscreen cosmetic composition containing a specific triazine-based compound with a particular structure, combined with another triazine compound and optionally a benzotriazol compound, which are used in specific proportions to enhance ultraviolet absorption across the UV spectrum, providing a broad-spectrum protection while maintaining skin safety and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of organic sunscreen agents are used to provide effective filtering of harmful ultraviolet radiation, then protection from UV-B and UV-A rays is improved, but physiological damage to the body occurs
Solution Approach 1:
The patent combines multiple types of ultraviolet absorbers (triazine-based compound of formula (1), triazine compound of formula (2), and optionally benzotriazol compound of formula (3)) in specific combinations and proportions. This composite approach allows the formulation to achieve broad-spectrum UV protection while distributing the concentration burden across multiple safer ingredients, thereby reducing physiological damage compared to using high concentrations of a single organic sunscreen agent
2Reliability
If inorganic substances like titanium dioxide are used to physically prevent skin exposure to ultraviolet rays, then sun blocking potential is improved, but skin whitening effect occurs and protection across the entire UV spectrum is inadequate
Solution Approach 1:
The patent specifies precise concentration ranges for each ultraviolet absorber component (triazine-based compound: 0.01-5% by mass, triazine compound: 0.01-5% by mass, benzotriazol compound: 0.01-3% by mass) to optimize both UV protection efficacy and skin compatibility. By controlling these parameters within defined ranges, the formulation achieves effective broad-spectrum protection while avoiding the skin whitening effect associated with inorganic substances like titanium dioxide
3Measurement precision
If a single ultraviolet absorber is used to protect against specific UV wavelengths, then absorption effectiveness at that wavelength is improved, but comprehensive protection against both short (UV-B and UV-C) and long (UV-A) wavelengths is insufficient
Solution Approach 1:
The patent employs a multi-functional ultraviolet absorber system where the triazine-based compound of formula (1) and triazine compound of formula (2) work synergistically to provide protection across multiple UV wavelength ranges. The triazine-based compound primarily targets UV-B and UV-C, while the triazine compound covers UV-A, creating a universal protection system that addresses the full UV spectrum rather than focusing on a single wavelength range
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 composition achieves excellent ultraviolet absorption at both short and long wavelengths, ensuring effective protection against UV-B, UV-A, and UV-C rays, with improved storage stability and skin compatibility, reducing the risk of skin damage from sunlight exposure.
Implementation Method 1
