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.

Claims

1. A spray delivery system comprising:

a container configured for spraying a liquid contained therein;

a sprayable liquid carrier housed within the container; and

an aggregate of microcapsules intermixed with the sprayable liquid carrier, the microcapsules each being formed of an external phase surrounding and encapsulating an internal phase such that there is a pressure differential between the internal phase and an external environment at a site of delivery, wherein the internal phase comprises a material selected from the group consisting of nicotine, flavorants, humectants, tobacco extracts, and combinations thereof, and wherein the external phase is hydrophobic and comprises a lipid.

2. An oral product comprising:

a smokeless tobacco material; and

a dressing material comprising an aggregate of microcapsules each formed of an external phase surrounding and encapsulating an internal phase such that there is a pressure differential between the internal phase and an external environment at a site of delivery;

wherein the internal phase is hydrophilic and comprises a material selected from the group consisting of nicotine, flavorants, humectants, tobacco extracts, and combinations thereof; and

wherein the external phase is hydrophobic and comprises a lipid.

3. The oral product of claim 2, wherein the smokeless tobacco material is a natural tobacco material.

4. The oral product of claim 2, wherein the smokeless tobacco material is a smokeless tobacco substitute.

5. The oral product of claim 4, wherein the tobacco substitute comprises microcrystalline cellulose.

6. The oral product of claim 4, wherein the tobacco substitute comprises beet fiber.

7. The oral product of claim 4, wherein the tobacco substitute is dissolvable under mouth conditions.

8. The oral product of claim 2, wherein the external phase is surrounding and encapsulating the internal phase as a hydraulic encapsulation.

9. The oral product of claim 2, wherein the external phase forms a substantially wall-like structure that is pseudoplastic and non-collapsible.

10. The oral product of claim 2, wherein the internal phase is a liquid.

11. The oral product of claim 2, wherein the aggregate of microcapsules is bioadhesive.

12. The oral product of claim 2, wherein the aggregate of microcapsules is configured for controlled release of the internal phase from the external phase based upon the pressure differential between the internal phase and the external environment at the site of delivery.

13. The oral product of claim 12, wherein the osmotic pressure differential is between the internal phase and saliva in the mouth of a user.

14. The oral product of claim 2, wherein each microcapsule in the aggregate of microcapsules comprises about 50% to about 98% by weight of the internal phase material based on the total weight of the microcapsule.

15. The oral product of claim 2, wherein the dressing material is carried at least partially by the smokeless tobacco material.

16. The oral product of claim 2, wherein the smokeless tobacco material is retained within a pouch.

17. The oral product of claim 16, wherein the dressing material is carried at least partially by the pouch.

18. The oral product of claim 16, wherein the pouch is a fabric pouch.

19. The oral product of claim 16, wherein the pouch is in the form of a sachet or fleece.

20. The oral product of claim 16, wherein the dressing material is carried by one of the smokeless tobacco material and the pouch, and wherein a different dressing material is carried by the other of the smokeless tobacco material and the pouch.

21. The oral product of claim 16, wherein the pouch is moisture-permeable.

22. The oral product of claim 2, wherein the smokeless tobacco material is substantially in a particulate, shred, or powder form.
