Everybody in cosmetic product development spends a lot of time on the selection of the right active ingredient but once it comes to the selection of the formulation, we just throw them in our standard formulations. Is this a smart thing to do? Via a discussion of the physicochemical properties of active ingredients for optimized skin penetration, we will look at the influence of skin penetration routes, formulation type, droplet size, emollients and emulsifiers. The day will be closed with a detailed discussion of the transfollicular penetration of nanoparticles.
At the end of this day you will know that your active ingredient may have the right activity profile but that it is the formulation that makes the active work. Only by selecting the right formulation will you get value for the money that you paid for your active ingredient. Formulating will never again be the same....
