Porous Ceramic Color Cosmetics for Matte Long-Wear Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions lack improved properties related to application ease, comfort, and long-wear resistance to external forces such as mechanical friction, water, sweat, sebum, and oil, particularly in lip compositions.
Innovation Solution
Incorporation of flattened, porous ceramic particles and a coloring agent in a physiologically acceptable medium, preferably in the form of an emulsion, to enhance water and sebum absorption, improve matte properties, and increase color intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicon resins such as MQ resins are used in lip compositions, then long wear properties and transfer resistance are improved, but application properties and feel upon application deteriorate (feels rough)
Solution Approach 1:
The patent employs porous silicone particles as the film-forming agent instead of conventional liquid silicon resins. These porous particles provide the necessary long-wear properties and transfer resistance while maintaining smooth application characteristics. The porous structure allows for controlled film formation that adheres to the lips without creating a rough feel, thus resolving the contradiction between durability and application comfort.
Solution Approach 2:
The invention creates a composite system combining porous silicone particles with specific plasticizers and film formers. This composite approach enables the composition to achieve both the mechanical durability needed for long wear and the tactile smoothness required for pleasant application. The synergistic interaction between the porous particles and accompanying ingredients produces a formulation that satisfies both reliability and ease of operation requirements.
2Ease of operation
If a topcoat composition is applied to improve application properties, then application properties are improved, but long-wear/transfer-resistance properties decrease
Solution Approach 1:
The patent merges the functions of long-wear formulation and smooth application into a single base composition. By incorporating porous silicone particles directly into the lip composition itself rather than requiring separate topcoat applications, the invention eliminates the trade-off between these two properties. The unified formulation achieves both durability and application comfort simultaneously, making the separate topcoat step unnecessary.
3Shape
If conventional fillers are used to improve matte properties, then matte properties are improved, but color intensity and application properties deteriorate
Solution Approach 1:
The patent utilizes porous silicone particles as the filler component to achieve matte properties. The porous structure provides surface texture that creates the desired matte finish while maintaining excellent application properties. Unlike conventional dense fillers that can compromise application smoothness, the porous particles integrate seamlessly into the formulation, delivering both aesthetic and functional performance.
