Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of cosmetic and dermatological compositions using ground pigments is complex, costly, and poses safety risks due to their pulverulent nature, requiring specialized and expensive grinding units, leading to difficulties in storage, transport, and integration into compositions.
Innovation Solution
A compound comprising at least 50% functional agent dispersed in a waxy matrix, with surface-treated solid particles to reduce absorption capacity, allowing easy integration into cosmetic and dermatological compositions through fluidization or solubilization, eliminating the need for specialized grinding units and enhancing safety and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ground pigments are used to color or enhance cosmetic compositions, then the aesthetic and organoleptic properties are improved, but the pulverulent nature makes storage, transport and handling complex and dangerous
Solution Approach 1:
The patent introduces a waxy matrix as an intermediary carrier that binds the ground pigment particles. This matrix transforms the problematic pulverulent state into a cohesive compound form, allowing the pigments to be handled as a unified material rather than loose powder, thus simplifying storage and transport while maintaining the desired aesthetic properties
Solution Approach 2:
The invention creates a composite material consisting of ground pigment particles embedded in a waxy matrix. This composite structure combines the beneficial properties of the pigments (coloration, mattifying effects) with the handling advantages of a bonded, non-pulverulent form, resolving the contradiction between manufacturing integration and storage complexity
2Manufacturing precision
If grinding units are used to reduce pigment particle size, then the aesthetic appearance is improved, but the equipment becomes specialized and expensive
Solution Approach 1:
The patent performs the grinding action during the formulation process itself rather than requiring separate preliminary grinding steps. The waxy matrix is incorporated along with the pigments in a single processing step, eliminating the need for specialized pre-grinding equipment and reducing overall process complexity
Solution Approach 2:
The waxy matrix serves multiple functions simultaneously: it acts as a carrier for the pigments, provides the bonding structure to prevent pulverulence, and can be processed in standard cosmetic formulation equipment. This multi-functionality eliminates the need for specialized grinding units while maintaining particle size control
3Manufacturing precision
If finer grinding of pigments is performed, then the aesthetic properties are enhanced, but the reactivity increases leading to degradation and safety risks
Solution Approach 1:
The waxy matrix acts as a protective intermediary that physically isolates the fine pigment particles from the environment. This barrier prevents direct exposure to moisture, oxygen and other degrading factors, thereby reducing chemical reactivity and safety risks while maintaining the fine particle size needed for aesthetic properties
Solution Approach 2:
The composite structure of pigment particles within the waxy matrix creates a protected environment for the pigments. The matrix material serves as a stabilizing medium that reduces the surface area exposure of the particles to harmful conditions, thereby reducing degradation rates while preserving the fine particle morphology needed for aesthetic effects
