B9728 - Physical-Chemical Properties of Cosmetics

Learning outcomes

The knowledge acquired by the students at the end of the course “Physical-chemical properties of cosmetics” concerns the thermodynamics and kinetics of solutions, emulsions and colloidal systems, the principles of the intermolecular interactions in complex systems affecting the physico-chemical parameters of interest (as polarity, viscosity, surface activity and adsorption) for the characterization and study of the properties of materials for cosmetics. Students will know the principles of the investigation of the redox properties of molecules and materials used in cosmetics and their possible interaction with living biostructures, together with the main characterization techniques and means for the determination of components (additives, solvents and salts) and for the evaluation of possible antioxidant processes for advanced formulations. Finally, the student will receive an introduction to the principles of scanning probe microscopy techniques for the surface characterization of bio- and nano-materials and the functional imaging for the interaction of such materials with biological systems.

Assessment methods

A preliminary written examination, lasting about 50 minutes, consisting in solving an exercise, followed by an oral discussion (about 25-30 minutes) concerning the topics taught during the lessons.

The use of AI is prohibited in the assessment. Any use of it constitutes a breach of academic integrity.

Teaching tools

• Slide projector;

• Laptop

Students with specific learning difficulties (SLD) or temporary or permanent disabilities: please contact the relevant University office as soon as possible (https://site.unibo.it/studenti-con-disabilita-e-dsa/it). The office will be responsible for proposing any necessary adjustments to the students concerned; such adjustments must, however, be submitted for approval by the lecturer at least 15 days in advance, who will assess their suitability, taking into account the course’s learning objectives.
