(*) Depending on your objectives, these studies can be realized without samples pre-irradiation for a first low-cost approach, or with samples pre-irradiation to take in account the possible formulations photo-instability phenomena. (**) Studies realized with samples pre-irradiation, according to European recommendation (26/9/2006).
