Jade Powder Cosmetic Composition for Blue Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic products, including sunscreens, fail to effectively block blue light, which can cause skin barrier dysfunction and inhibit keratinocyte differentiation due to its damaging effects on mitochondrial DNA and cellular functions.
Innovation Solution
A cosmetic composition containing jade powder, specifically Chuncheon jade powder with particle sizes ranging from 10 nm to 100 μm, is formulated to block blue light, providing a blue light-blocking effect by reflecting light in the blue light spectrum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sunscreen agents are used to protect skin from light damage, then skin protection is improved, but blue light blocking effectiveness is insufficient
Solution Approach 1:
The patent changes the optical parameters of the cosmetic composition by incorporating jade powder particles with specific size ranges (1-10 μm, 10-100 μm, or 100 μm) to achieve effective blue light blocking. The jade powder's refractive index and particle size are optimized to maximize scattering and absorption of blue light wavelengths (380-500 nm) while maintaining skin protection functionality.
Solution Approach 2:
The patent creates a composite cosmetic composition combining jade powder with traditional sunscreen agents and cosmetic base materials. This composite formulation integrates the blue light blocking properties of jade powder with the UV protection capabilities of conventional sunscreens, achieving comprehensive light protection across different wavelengths.
2Reliability
If jade powder is added to cosmetic composition, then blue light blocking is improved, but formulation complexity increases
Solution Approach 1:
The jade powder serves multiple functions simultaneously: it blocks blue light through scattering and absorption, provides physical UV protection, and acts as a cosmetic ingredient with potential skin benefits. This multi-functionality reduces the need for separate additives and simplifies the overall formulation approach.
Solution Approach 2:
The patent specifies particular particle size ranges for the jade powder (1-10 μm, 10-100 μm, or 100 μm) to optimize blue light blocking while ensuring proper formulation behavior. By controlling the particle size distribution, the patent achieves effective blue light protection without compromising formulation stability, spreadability, or aesthetic properties.
