A process for evaluating efficacy of a deodorant product includes: introducing sweat into a main channel formed in a fluidic device satisfying particular requirements; measuring a flow rate of the sweat in the main channel and transmitting the flow rate to a controller; imposing a pressure set point on the pressure actuator by closed-loop control so the flow rate of the sweat in the main channel is controllable; contacting the sweat and a deodorant product and reacting the sweat and the deodorant product with each other, the deodorant product being provided in a particular manner, wherein while the sweat and the deodorant product react with each other, the flow rate of the sweat in the main channel is maintained at substantially zero; and determining at least one of a physicochemical parameter and a biological parameter of a product of the reaction between the sweat and a the deodorant product.

A microfluidic device and method for producing and collecting single droplets of a first fluid, the device including a microfluidic platform having at least a droplet microchannel wherein is produced a flow of single droplets of the first fluid dispersed in a second fluid immiscible with the first fluid, the droplet microchannel having at least one inlet extremity and at least one outlet extremity for distributing the flow of droplets, the device further including:

Microfluidic device for production and collection of droplets of a fluid

This applicator comprises a base () and a product applicator tongue () that projects from the base () along an axis (A-A'), said tongue () defining a central cavity (). It comprises a massage element () disposed in the central cavity (), with the massage () element and the tongue () defining therebetween in the cavity () an intermediary product retaining space (). The massage element () and the tongue () can move in relation to one another transversally in relation to the axis (A-A&#x2032;).

Microfluidic evaluation system for evaluating the efficacy of an antiperspirant product and associated method

A microchannel formed at the interface of two layers of material, at least one of the two materials being a substrate. A volume of the microchannel contains a film of polymer fixed by covalent bonding to the substrate layer. The film of polymer being formed from a hydrogel material susceptible to undergoing changes in volume under the action of an external stimulus. The hydrogel polymer is chosen from those which are sensitive to changes in temperature, light, electrical field or pH. A method for producing the microchannel.
