Surfactant-Free Cosmetic Emulsification via Channel Vortex Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cosmetic manufacturing process often requires surfactants, which customers prefer to avoid due to their lack of functional relevance, leading to increased complexity and production costs when alternative methods like special raw materials or procedures are used.
Innovation Solution
An apparatus that mixes internal and external phase fluids without surfactants, using a housing with multiple containers and a channel unit that generates emulsions by manipulating fluid flow to create vortices, allowing for the production of surfactant-free cosmetics at a lower cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If surfactant is used to emulsify two fluids, then emulsification is achieved, but cosmetic function is compromised and customer preference is reduced
Solution Approach 1:
The invention extracts and eliminates the surfactant component from the emulsion system. By removing the harmful substance (surfactant) that compromises cosmetic function, the patent achieves emulsion stability through alternative means (mechanical mixing in the channel unit) while maintaining cosmetic efficacy.
2Object-generated harmful factors
If special raw materials or procedures are used to manufacture surfactant-free cosmetic, then cosmetic function is improved, but manufacture process complexity and production cost increase
Solution Approach 1:
The invention enables the system to self-emulsify through its own structural design (channel unit with specific flow paths) without requiring external special materials or complex procedures. The apparatus performs the emulsification function inherently through its geometry and fluid dynamics, eliminating the need for additional special raw materials or complex manufacturing steps.
Solution Approach 2:
The invention changes the physical parameters of the system by using specific flow rates, pressure differentials, and channel geometries to achieve emulsification. By controlling fluid flow parameters (more external phase fluid than internal phase fluid) and channel structure (mixing sections with vortices), the system achieves surfactant-free emulsion without complex procedures.
3Stability of the object's composition
If special facility like high frequency focused ultrasound is used, then surfactant-free emulsion is achieved, but production cost increases
Solution Approach 1:
The invention replaces complex mechanical systems (high frequency focused ultrasound facilities) with a simpler mechanical mixing system based on fluid dynamics. The channel unit uses flow-induced vortices and pressure differentials to achieve emulsification, substituting expensive specialized equipment with a cost-effective geometric design that achieves the same emulsion stability.
