Programme

Part 1 - Flexible study: online distance learning (31 March  - 2 October 2008) 

Five inter-related modules covering:

• Optimising product stability
• Introduction to practical rheology
• Emulsion and microemulsion technologies
• Using dispersants in formulations
• Surfactant chemistry and architecture 

Part 2 - One-day workshop (25 September 2008)

A series of practical demonstrations and hands-on experiments based around realistic case study scenarios.

Aimed at consolidating the online training modules and providing opportunities to question experts and network with other participants, the central theme will cover colloidal stability in formulations.

The practical elements of the workshop will be built around the following;

• Recognition of colloidal instability, including an appreciation of flocculation, coagulation and coalescence.  Methods may include, but are not limited to, particle and droplet size and size distribution determination (laser light diffraction, Lasentec) and temporal changes; conductivity and dielectric determinations.
• Recognition of sedimentation and creaming instability . Methods such as Turbiscan and diffusion coefficient determination may be used.
• Routes to colloidal stabilisation. Milling dispersions with stabilisers, polymeric dispersants and/or surfactants, and the effects observed.
• Storage stability/shelf life prediction. Rheological techniques will be used to assess the lifetime over which formulations are stable.
