Micaceous Pearlescent Pigment Cosmetic Composition Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solidified compact powdery cosmetic compositions with high levels of pearlescent pigments suffer from low stability and ease of breakage, which can be improved by adding fillers or binders, but this reduces shininess and color intensity.
Innovation Solution
A cosmetic composition combining micaceous and pearlescent pigments in a solid form, with a high content of spherical particles, providing stability, high color intensity, and metallic finish, while minimizing the use of conventional fillers and binders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fillers or binders are added to improve stability, then stability is improved, but shininess and color intensity are reduced
Solution Approach 1:
The patent combines micaceous pigment particles with spherical particles to create a composite cosmetic composition. This composite structure provides both stability (from the micaceous pigment's layered structure) and high shininess/color intensity (from the spherical particles' light-reflecting properties), resolving the contradiction between stability and visual performance without requiring additional fillers or binders
2Stability of the object's composition
If conventional fillers or binders are added to reduce breakage, then stability is improved, but the composition requires more ingredients increasing complexity
Solution Approach 1:
The spherical particles in the composition serve multiple functions simultaneously: they provide structural stability to prevent breakage, contribute to the metallic finish and shininess, and act as a pigment carrier. This multi-functionality eliminates the need for separate fillers and binders, reducing composition complexity while maintaining stability
