OPTIMIZATION OF HAIRSTYLING PASTES FOR THE IMPROVEMENT OF FIXATION AND THE REDUCTION OF STICKINESS AND RESIDUES I studied the influence of components on the performances of hairstyling pastes by following two parallel focuses - I substituted the thickener by testing natural raw materials. I realized a mapping of textures to highlight zone of interest - I used Experimental Design: I formulated pastes and evaluated them in terms of viscosity, fixation and stickiness in collaboration with other departments

EXTRACTABLES & LEACHABLES STUDIES OF A PARENTERAL AND OPHTHALMIC DRUG PRODUCTS PACKAGING FOR THE PRODUCT QUALITY RESEARCH INSTITUTE (PQRI) I led controlled extraction studies on the packaging components and determined their extractables by using chromatographic analysis (GC/MS,HPLC/DAD,HS-GC/MS,TDU/MS). I also simulated a migration study on the label to define the potential leachables among the extractables.

Participation in all the process of analysis, from sampling to analytical tests. Autonomy and responsibility with clients.
