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, we also include a comprehensive description 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. Recent updates to the course mean that we are now also focusing on alternatives to historical microencapsulation systems in response to the recent microplastics regulations, which is driving the industry towards developing biodegradable alternatives. This year’s course will feature sessions to better understand the regulation environment, to specifically describe alternative microcapsule shell materials that are more environmentally friendly and some discussion around biodegradability testing.

How will I benefit?
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.


Throughout the course the theory will be supported by some live and/or pre-recorded practical lab demonstrations as well as a trouble shooting forum.

What our delegates say

“It’s an excellent course that not only covers the basics of microencapsulation but also covers some industrial applications with all it’s advantages and disadvantages.” 
Isabel Sousa, University of Aveiro

“The course was an excellent opportunity both to review/get exposed to the primers of microencapsulation whilst also allowed discussions on advanced and more specific topics.”
Julio Uribe-Padilla, Eurofragance S.L.U

“It was the best "microencapsulation course" I attended, and I truly recommend to all that works or want to work in this field.”
Ricardo Costa, Devan Chemicals
