Abstract
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.
