Manufacturing method improves microcapsule production

Cambridge Consultants has developed a process that allows for flexibility and consistency of manufacturing

Cambridge Consultants has developed a method of continuously manufacturing microcapsules, increasing agility and making personalisation possible, such as in the pharmaceutical industry.

This method of production of microcapsules will enable the process to be manipulated in real-time, providing manufacturers with flexibility and the ability to tailor it to different industries.

Microcapsules are small droplets – less than 0.1mm in diameter – of a delicate material enclosed by a protective coating. These are used to preserve flavouring in chewing gum, the fertiliser and pesticides used on crops, or the fragrance in laundry. Microcapsules ensure that the release of ingredients in products occurs at the right moment.

The manufacturing method will increase process control, yield and agility, according to the company. Classically, microcapsules are manufactured in bulk and, as a result, manufacturing is inflexible and uneconomic for small batches.

Andrew Strong, head of manufacturing innovation at Cambridge Consultants, said: “This approach allows the continuous monitoring of produced microcapsules and enables real-time control of the process. This can lead to improved controllability, consistency and yield of the finished product, and reduced waste for operators. Development costs are reduced by removing the need to produce a full batch. This makes it easier for manufacturers to tailor the chemistry to the application – for example, producing biodegradable shells.”

Microcapsules are distinct from microbeads, which are tiny pieces of plastic.
