Title:
ENCAPSULATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/030995
Kind Code:
A3
Abstract:
The invention pertains to an encapsulation system; in particular a 3- phase system comprising an inner, second and outer phase wherein the second phase is gaseous, and wherein the 3-phase system has a lifetime of at least 3 min and the second phase has a diameter of less than 1 mm. An example of such a system is a stable, small antibubble. Also, the invention pertains to methods of making such 3-phase systems, and to use and methods of use thereof. In particular, 3-phase systems according to the invention are stabilized by surface active particles or molecules, such as for instance colloidal particles. The 3-phase systems of the invention can include a variety of other compounds, and can among others be used in pharmaceutical- or food-based applications. In particular, a 3-phase system according to the invention, such as for example an antibubble, may deliver pharmaceutical compounds.
