Teaching in the second semester

Units courses prerequisite and corequisite :

Prerequisite or corequisite units are presented within each program

Learning unit contents :

Water, hydrophobicity, hydrophobic interactives Rheology Colloïdal systems Colloïdal stability (electrostatic stabilization and DLVO theory) Zeta potential Surface tension and surface free energy - cohesion and adhesion energies - spreading coefficient - Gibbs adsorption isotherm Physical states of matter Soft matter Emulsifiers properties : hydrophile-lipophile balance, phase diagram, CMC

Learning outcomes of the learning unit :

To lay the foundations of physico-chemical properties that influence formulation stability especially colloïdal stability.
