Methylene Blue Sunscreen Composition for UVA and UVB Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreens containing Oxybenzone and Octinoxate are ineffective in blocking UVA radiation, pose health risks, and contribute to coral bleaching, while existing sunscreens often prioritize UVB protection over UVA, neglecting extrinsic skin aging and coral health.
Innovation Solution
A sunscreen formulation using Methylene Blue as the active ingredient, which provides both UVA and UVB protection without harming coral health, and enhances skin cell recovery and ROS reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sunscreen agents (Oxybenzone and Octinoxate) are used, then UVB protection is achieved, but UVA protection is insufficient and harmful effects occur
Solution Approach 1:
The patent removes the harmful conventional sunscreen agents (Oxybenzone and Octinoxate) from the formulation and replaces them with Methylene Blue, which provides both UVA and UVB protection without the harmful side effects. This extraction of the problematic components while maintaining the protective function resolves the contradiction between UVB protection and harmful effects.
Solution Approach 2:
The patent changes the chemical composition parameter by introducing Methylene Blue at specific concentrations (0.1-2 μM) to achieve broad-spectrum protection. This parameter change enables the sunscreen to block both UVA and UVB radiation simultaneously, resolving the insufficient UVA protection while maintaining UVB protection.
2Reliability
If Oxybenzone and Octinoxate are used as active ingredients, then sunscreen function is provided, but endocrine disruption and coral bleaching occur
Solution Approach 1:
The patent converts the harmful effects of conventional sunscreens into benefits by using Methylene Blue, which not only provides sunscreen function but also reduces reactive oxygen species (ROS) and promotes skin cell recovery. This transforms the paradigm from harmful protection to beneficial protection, eliminating endocrine disruption and coral bleaching while maintaining sunscreen efficacy.
Solution Approach 2:
Methylene Blue acts as an intermediary substance that mediates between the need for sunscreen protection and the avoidance of harmful effects. It provides the protective function while simultaneously reducing ROS and avoiding endocrine disruption, serving as a bridge that resolves the contradiction between effectiveness and safety.
3Measurement precision
If SPF standard prioritizes UVB blocking, then UVB protection is enhanced, but UVA-induced photoaging protection is inadequate
Solution Approach 1:
The patent employs Methylene Blue as a multi-functional agent that simultaneously provides both UVA and UVB protection, unlike conventional agents that primarily target UVB. This universal protective capability ensures comprehensive sun protection, addressing both UVB burning and UVA photoaging with a single ingredient.
