Dedika is a platform where you learn by doing: whether it's putting together a business proposal, becoming a nail technician, or learning to use a new tool. No matter your goal, the best content on the subject already exists. The problem is, it's often in another language, expensive, scattered around, lacks practical activities, or comes in courses that are too long for busy people. That's why Dedika has its own method: we find this material wherever it is, organise what makes sense for your goal, review it with the help of experts who are available to answer your questions, and create practical exercises so you can learn by doing. You are the most important part of your journey and no one knows it better than you: choose the content and course length, decide if you want to learn online or offline, and pick your preferred format. It could be video, text, audio, or a summary. Your way, with only what matters to you. Here, every moment you dedicate counts for more, and you reach what matters faster.

Our courses include a summary at the end of each chapter, which you can download as a PDF and print.

For all levels

Microencapsulation and Time-Release Course

Name: Microencapsulation and Time-Release Course
Price: 1794 ZAR

Master the science and engineering of microencapsulation and controlled-release systems, from shell material selection to kinetic modelling and industrial-scale manufacturing. This course equips formulation scientists, R&D engineers, and product developers with the technical depth to design, characterise, and optimise encapsulated products across pharmaceutical, food, agricultural, and cosmetic sectors.

Dedika for businesses

What you will learn:

You will gain a thorough understanding of encapsulation techniques including coacervation, spray drying, interfacial polymerisation, and microfluidics, along with the physical and chemical principles that govern each process. You will learn how to evaluate shell materials, assess payload compatibility, and apply mathematical models to predict and control release profiles. The course covers advanced characterisation methods, quality-by-design frameworks, and design-of-experiments approaches for formulation optimisation. You will also explore regulatory pathways across multiple industries and apply sustainability principles to encapsulation process design. By the end, you will be prepared to lead encapsulation development projects from concept through commercialisation.
