Formulation Engineering for Pharmaceutical, Cosmetic, Food and Oil & Gas Industries
Complex multiphase fluids include emulsions (liquid-liquid systems), foams (gas-liquids), and dispersions (solids in fluids) among many other systems. The behavior of these systems is partly controlled by the principles of fluid mechanics, but also by the principles of colloid chemistry. A formulation engineering approach to tackle these problem seeks to connect the chemical (colloidal) properties of the interfaces with the physical (fluid mechanics) characteristic of the process in order to define the process conditions/composition required to achieve the desired outcome. This approach will be discussed through a two examples, one on the separation of crude oil emulsions in offshore platforms, and another one on the design of self-emulsifying delivery systems for pharmaceuticals and nutraceuticals. Reflections from these two examples will be used to illustrate some of the basic principles required to engineer processes or products that involve surfactants systems.
Edgar J. Acosta his B.Sc. in Chemical Engineering (Summa Cum Laude) from the Universidad del Zulia (Venezuela) in 1996, and his M.Sc. and Ph.D. in Chemical Engineering from the University of Oklahoma in 2000 and 2004, respectively. He is currently a Professor of the Department of Chemical Engineering and Applied Chemistry of the University of Toronto. Dr. Acosta received the Provost Dissertation Award from the University of Oklahoma (2005), the Akzo-Nobel “Ralph Potts” award (2002), and the AOCS S&D best paper award (2004, 2008 and 2012), the AOCS Young Scientist Award (2010), and the Syncrude Innovation Award (2012). Dr. Acosta has published over 90 research articles, 8 book chapters, 2 patent applications, and has been author or coauthor of over 160 presentations at international conferences. His research encompasses the area of colloids, complex fluids and formulation engineering.
