Emulsions and Emulsification

Emulsions are structured systems which contain two liquids which are usually immiscible such as water and oil. According to the size of the dispersed phase fragments, they are called macro-, mini- or nanoemulsions, and microemulsions when they exist as a single phase system. Emulsions can be made through mechanical energy supply processes which are common place processes in chemical engineering, or by tricky transition phenomena such as phase inversion or spontaneous emulsification, which are at the technological edge so far. Emulsions are found in scores of applications such as pharmaceuticals, cosmetics, foods, drilling fluids, paints, asphalt conditioning, cleaning products, green fuels and so forth.

Scope

This symposium is dedicated to the technical aspects of emulsions and emulsifications.

The proposed topics are :

Emulsion formulation and properties

  • New trends in emulsion formulation
  • Emulsion as new material (template, vehicle, separation methods)
  • Emulsions as conditioning
  • Emulsion persistence issues
  • Emulsion rheology and applications

Emulsification by strong mechanical energy supply

  • Energy spending versus advantages
  • New high shear methods
  • Ultrasonic emulsification
  • Other

Emulsification by low energy methods

  • Transitional inversion methods (PIT etc)
  • Catastrophic inversion techniques (waterboren resins etc)
  • Spontaneous emulsification
  • Tricks to enhance emulsification performance

Emulsions in ChE processes, particularly “green applications”

  • Micro/macroemulsions as solvent substitute and in cleaning formulas
  • Emulsions for metalworking (lamination, cutting oils)
  • Nanoemulsions as catalytic grain precursor
  • Emulsions in separation methods (extraction and other)
  • Emulsions in oil and fat conditioning for foods, cosmetics etc
  • Emulsion breaking processes (particularly in waste water treatments)

Publication

This symposium will be included in the WCCE8 proceedings. However, we encourage the submission of the full articles dealing with surfactants (particularly green products), emulsifiers, formulation, practical aspects on making and processing macro and microemulsions including oils and fats to the “Journal of Surfactants and Detergents” (a Journal of the American Oil Chemists’ Society published by Springer Verlag, Berlin).
