Microencapsulation Techniques

SwRI scientists continue to develop and discover diverse microencapsulation techniques for pharmaceuticals, food and nutrition, polymer and materials science, and process engineering. Our team can help solve product stability such as release and application problems for a wide range of industries. Our diverse, extensive encapsulation methods solve product performance requirements for clients.

With more than 60 years of encapsulation research and development experience, SwRI is a leader in the field. Using extensive expertise in diverse technical fields such as pharmaceuticals, food and nutrition, polymer and materials science, and process engineering, our encapsulation specialists solve product stability, release and application problems in a wide range of industries. We have conducted more than 1,000 encapsulation research programs for commercial and government clients, employing diverse encapsulation methods to solve product performance requirements for our clients. Encapsulation methods are broadly categorized as either physical or chemical.
