SwRI: Encapsulation Process Comparisons, including microencapsulation, nanoencapsulation, pharmaceutical encapsulation, food encapsulation, nutraceuticals, agricultural encapsulation, industrial encapsulation, and cosmetics microencapsulation.

When selecting the appropriate encapsulation process to meet customer objectives, Southwest Research Institute (SwRI) scientists, with collaborative support from clients, evaluate and balance a variety of performance and formulation criteria.
