Micropore -Pharmaceutical Encapsulation Process

The ‘science and art’ of microencapsulation, is a way of taking an active ingredient, using a particular technique to encapsulate it, so that it remains isolated, protected and stable until such time that it is released by a certain trigger mechanism.

There are also some hybrid techniques that use physical mechanisms to form a droplet or particle, so that chemical techniques can then be utilised.

Micropore’s patented membrane emulsification process is capable of producing uniform droplets from 10µm upwards, that can then be post-processed with a variety of chemistries to provide a microcapsule, or microparticle system with the desired properties. Generally, encapsulation technologies are divided into two groups – chemical encapsulation and physical encapsulation.

Some examples of physical encapsulation technologies include, spray drying, spray chilling, freeze drying, fluid bed coating, etc.

Encapsulation systems can be designed to:

• Trigger the release of selected active ingredients during application.
• Deliver a tailored release profile to suit formulation and application.
• Prevent unwanted interaction between ingredients during the mixing of components.
• Mask undesirable components (sharp tastes, low fat elements).
• Protect ingredients from oxidation during application (eating, ingestion, spraying).
• Extend the shelf life of products.
