Jade Sphere Composite Powder for Cosmetic Lumping and Skin Feel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jade powder particles in cosmetic compositions exhibit poor skin feel due to coarse surfaces and can cause a white cast and lumping, leading to degraded whiteness and applicability issues.
Innovation Solution
A composite powder, referred to as jade sphere, is created by uniformly impregnating jade powder particles in a porous polymer using a one-step spray drying or electro-spraying process, where the jade powder is dispersed in a solution with a dissolved porous polymer, enhancing cosmetic durability and preventing lumping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If jade powder particles are used in cosmetic compositions, then blue light-blocking and skin whitening effects are achieved, but coarse surface texture causes poor skin feel and lumping
Solution Approach 1:
The patent uses porous polymer particles as a carrier matrix to embed jade powder particles. The porous structure allows for uniform distribution of jade particles while the polymer matrix smooths the coarse surface texture, preventing lumping and improving skin feel while maintaining the cosmetic benefits of jade powder
Solution Approach 2:
The patent creates a composite material system consisting of porous polymer particles combined with jade powder particles. This composite structure integrates the functional properties of jade (blue light-blocking, whitening) with the textural benefits of porous polymer (smoothness, anti-lumping), resolving the contradiction between cosmetic performance and skin feel
2Manufacturing precision
If a two-step coating process is used to manufacture composite powder, then powder characteristics are preserved, but the manufacturing procedure becomes complicated
Solution Approach 1:
The patent combines the dispersion and coating steps into a single spray drying process. The jade powder is dispersed in a polymer solution, and spray drying simultaneously forms the porous polymer matrix and embeds the jade particles, achieving composite powder formation in one step rather than requiring separate coating operations
Solution Approach 2:
The patent uses spray drying parameters (atomization, hot air temperature, drying time) to control the formation of porous polymer particles and the embedding of jade powder. By optimizing these parameters, the process achieves uniform particle formation and proper jade particle distribution without requiring multiple processing steps
