Cosmetic Powder Preparation via Multi-Phase Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic products like pressed powders crumble over time and require skill to apply, while loose powders are limited to professional use due to application difficulties.
Innovation Solution
A multi-phase mixing process involving a fatty emulsion, colouring powders, and a solvent, followed by drying, eliminates the need for extrusion, resulting in a compact, long-lasting, and shimmery cosmetic product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If pressed powders are used to achieve compactness, then the product structure is improved, but the product crumbles after use and dirties the container
Solution Approach 1:
The patent changes the physical and chemical parameters of the cosmetic formulation by incorporating specific fatty substances (15-30% by weight), solvents (5-20% by weight), and colouring powders (40-60% by weight) in optimized ratios. This parameter optimization allows the powder to maintain compact structure while preventing crumbling during use.
Solution Approach 2:
The invention creates a composite material system combining fatty substances, solvents, and colouring powders. This composite structure provides both the compactness needed for pressed powder form and the durability to prevent crumbling, as the fatty substances act as binders holding the colouring powder particles together.
2Ease of operation
If loose powders are used to achieve ease of application, then the product is easier to apply, but it requires professional skill and is limited to professional use
Solution Approach 1:
The patent optimizes particle size distribution and surface properties of the colouring powders through controlled milling and classification processes. This creates a powder with optimal flow characteristics that can be easily applied by consumers without professional training, while still providing good adhesion and coverage.
Solution Approach 2:
The invention incorporates fatty substances that provide localized lubrication and adhesion properties on the powder particles. This local quality enhancement allows the powder to glide smoothly during application (ease of operation) while maintaining sufficient grip on the skin (user accessibility).
3Shape
If extrusion process is used to achieve compactness and sheen, then the product structure is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent extracts and eliminates the extrusion step from the traditional manufacturing process. By formulating the mixture with optimized fatty substance content (15-30%) and solvent ratios (5-20%), the mixture becomes self-compacting and can be directly pressed into the final form without requiring complex extrusion equipment or processes.
Solution Approach 2:
The invention changes the formulation parameters to achieve spontaneous compaction. The specific ratio of fatty substances to colouring powders (15-30% vs 40-60%) creates a mixture with optimal binding properties that allows direct pressing, eliminating the need for extrusion while maintaining compactness and sheen.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The process produces cosmetic products with optimal compactness, direct application ease, and a creamy finish, offering an economical alternative to traditional powders and creams.
Implementation Method 1
an emulsion of fats for cosmetic use; a mixture of colouring powders; and a solvent for cosmetic use
Implementation Method 2
a mixture obtained by mixing a powdery phase and a fatty emulsion
Implementation Method 3
The thus obtained is placed over another cosmetic product and dried
Implementation Method 4
dried, for example in an oven, in a vacuum or by fluid bed, but it is preferably performed in the air, at room temperature
