Microencapsulation

About the course

What will I learn?
This course covers the basic science and engineering of microencapsulation across a wide range of applications including the important stages of emulsification control, stability and release property control. While the majority of the course involves emulsions, multiple emulsions and particle coating are also included as well as details of the range of valuable characterisation tools and their applicability. The emphasis is on understanding the flow behaviour of the interaction of the various components in such complex systems. This should provide the basis for a rational approach to formulating and producing micro encapsulates to meet a range of needs.

The course offers a programme of academic and industry cooperation taking delegates from the basic science through to manufactured products. 

On completion of this course you’ll have an understanding of:

  • developing a rational approach to formulate or modify emulsions for optimal processing behaviour, and using available laws and scaling relations to predict behaviour

  • the various methods of turning emulsions into encapsulates, including the process conditions that impact their final properties and behaviour

  • selecting characterisation devices and defining measurement procedures for a specific application

  • evaluating and interpreting experimental data.

Who should attend?

This course is for you if you’re a scientist or engineer in the chemical, petroleum, polymers, coatings, inks, food, pharmaceuticals, cosmetics or general chemical industries with responsibility for R&D projects, process engineering, manufacturing or product formulation involving incorporating microencapsulates into formulated products.
