Summary
1. Emulsion formation 2. Destabilisation of an emulsion (creaming/sedimentation, Ostwald ripening, flocculation, coalescence) 3. Emulsions and microemulsions 4. Superficial and interfacial tensions (Marangoni effect, Laplace's law, Jurin's law) 5. Physico-chemistry of emulsifiers 6. Emulsion formulation strategy (surfactant selection criteria, Griffin's HLB , HLB method, Winsor Fish Diagrams, HLD approach) 7. Emulsification processes (transitional phase inversion, catastrophic) 8. Case study (cosmetic and polymer emulsions, bitumens, etc.)
Educational goals
At the end of the course, students will be able to: - Recognise the nature of an emulsion, know how to characterise it through physico-chemical analyses - Differentiate between an emulsion and a microemulsion, recognise destabilisation mechanisms - Develop a strategy for choosing a surfactant and the process for formulating an emulsion - Know how to interpret a formulation/composition conceptual map
Sustainable development goals
Knowledge control procedures
Continuous Assessment
Comments: Written exam (one hour) or presentation of projects
