Abstract
The present disclosure relates to compositions that are useful in the delivery of various materials. In particular, the compositions comprise a suspension wherein an internal phase material is surrounded by an external phase material. The internal phase specifically can be a hydrophilic material, and the external phase specifically can be a hydrophobic material. The materials are combined so that the internal phase is substantially encapsulated by the external phase such that release can be controlled in relation to osmotic pressure differentials. The suspension can be combined with a carrier, and various systems and products can be formed with the suspension and optional carrier, such as oral strips, spray delivery systems, smokeless tobacco products, aerosol delivery devices, cigarettes, and packaging.
