The aim of the technology is to realize a continuous flow emulsion of a mixture based on an natural or synthetic oil and water, with less surfacting agents. The formation of a disperse flow is based on a microfluidic device with microchannels and one or several singularities (ie 90° elbows). High speed (velocity between 1 and 3 m/s) impinging of water and the oily phase triggers continuous emulsification. The break-up process is improved thanks to the circulation of the emulsion through several 90° elbows.
These flows can release a W/O or O/W emulsion for pharmaceutical or cosmetic applications. This device is used to produce continuously an emulsion (droplet size between 5 to 10 µm) with a flow range compatible with industrial applications (up to 600 mL/min for each device). The assembly of several devices can be used to increase the flow.
This device is the solution for a time-saving and low cost emulsification process dedicated to pharmaceutical and cosmetic emulsions.
