93860 - Properties Of Cosmetic Materials.

Learning outcomes

After having attended and passed the final exam of the course "Properties of cosmetic materials" the student has acquired:

• knowledge of thermodynamics of solutions, emulsions and of intermolecular interactions in complex systems;
• knowledge of the physico-chemical parameters (polarity, viscosity, surface activity...) of interest for the characterization and study of the properties of materials for cosmetics;
• knowledge of the redox properties of molecules and materials of the cosmetics and their possible interaction with living biostructures;
• knowledge of the main characterization techniques and the means for the evaluation of components (additives, solvents and salts) for advanced formulations;
• knowledge of the main scanning probe microscopy techniques for the surface characterization of the bio and nanomaterials and the functional imaging of their interaction with biological systems.
