Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glitter materials used as lame agents contain resin pieces, which contribute to marine plastic pollution and result in dull, insufficiently chromatic colors.
Innovation Solution
A glitter material composed of glass flakes coated with a titanium oxide film, ensuring a D50 of 100 µm or more, with standard deviations of a* and b* in the L*a*b* color system of 11 or less, and a D10 of 65 µm or more, to enhance color uniformity and chroma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If resin pieces are used as lame agent, then glitter effect is achieved, but marine pollution and dull color occur
Solution Approach 1:
The invention extracts and eliminates resin from the glitter material composition, replacing it with inorganic materials (mica and titanium oxide). This removal of the harmful substance (resin) directly addresses marine pollution while maintaining the glitter effect through alternative materials with different optical properties.
Solution Approach 2:
The invention changes the material composition parameters from organic resin to inorganic materials (mica substrate with titanium oxide coating). This parameter change transforms the material properties, eliminating pollution concerns while achieving the desired glitter effect through the optical properties of the inorganic coating structure.
2Object-affected harmful factors
If resin-free glitter material is used, then environmental friendliness is improved, but color chroma becomes insufficient
Solution Approach 1:
The invention employs a composite material structure consisting of a mica substrate combined with a titanium oxide coating layer. This composite structure leverages the optical interference properties of the titanium oxide film on the mica base to generate vibrant colors and high chroma, thereby achieving excellent color development without using resin materials.
Solution Approach 2:
The invention utilizes the optical interference phenomenon of the titanium oxide coating to produce vivid color effects. By controlling the coating thickness and optical properties, the material achieves high color chroma and saturation, transforming the color performance to meet cosmetic application requirements while remaining environmentally friendly.
3Illumination intensity
If large particle size is used for lame agent, then glitter effect is enhanced, but color uniformity decreases
Solution Approach 1:
The invention optimizes the particle size parameters within a specific range (D50: 100-500 μm, D10: 65-200 μm) to achieve the optimal balance between glitter effect and color uniformity. This parameter optimization ensures that the particles are large enough to provide strong glitter while small enough to maintain consistent color distribution across the material.
Solution Approach 2:
The invention ensures uniform color distribution by maintaining consistent coating quality and thickness across all particles in the size range. The titanium oxide coating is uniformly applied to each mica flake, ensuring that local color properties are consistent throughout the material, which prevents color variation even with larger particle sizes.
