Abstract

An oral product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-soluble polymer matrix, cellulosic fibers embedded in the mouth-soluble polymer matrix, and nicotine or a derivative thereof dispersed in the mouth-soluble polymer matrix. The oral product is adapted to release the nicotine or a derivative thereof from the body when the body is received within the oral cavity and exposed to saliva.

Claims

1. An oral product, comprising a body that is wholly receivable in an oral cavity, the body comprising:

a mouth-soluble polymer matrix, the oral product comprising between 40 and 80 weight percent of one or more mouth-soluble polymers;

at least 10 weight percent of non-tobacco cellulosic fibers embedded in the mouth-soluble polymer matrix, the non-tobacco cellulosic fibers comprising cellulose, the non-tobacco cellulosic fibers having an average fiber size of 20 micrometers or less; and

nicotine or a derivative thereof dispersed in the mouth-soluble polymer matrix such that the nicotine or derivative thereof is released from the body when the body is at least partially received within the oral cavity and exposed to saliva,

wherein the non-tobacco cellulosic fibers are configured to provide passages in the mouth-stable polymer matrix to pores retaining the nicotine or derivative thereof, the pores having diameters of between 40 and 60 microns;

wherein the body defines channels formed adjacent the non-tobacco cellulosic fibers; and

wherein the oral product is substantially free of tobacco plant tissue.

3. The oral product of claim 1, wherein the mouth-soluble polymer matrix comprises starch.

4. The oral product of claim 1, further comprising a plasticizer dispersed in the mouth-soluble polymer matrix.

5. The oral product of claim 4, wherein the plasticizer is selected from the group consisting of propylene glycol, glycerin, vegetable oil, triglycerides, and combinations thereof.

6. The oral product of claim 1, further comprising a sweetener dispersed in the mouth-soluble polymer matrix.

7. The oral product of claim 6, wherein the sweetener is selected from the group consisting of saccharine, sucralose, aspartame, acesulfame potassium, and combinations thereof.

8. The oral product of claim 1, wherein the nicotine is tobacco-derived nicotine.

9. The oral product of one of claim 1, wherein the nicotine is synthetic nicotine.

10. The oral product of claim 1, further comprising an additive selected from the group consisting of minerals, vitamins, dietary supplements, nutraceuticals, energizing agents, soothing agents, amino acids, chemsthetic agents, antioxidants, botanicals, teeth whitening agents, therapeutic agents, and combinations thereof, wherein the additive is dispersed in the body or cellulosic fibers such that the additive is released when the body is held within a mouth of an adult consumer.

11. The oral product of claim 1, further comprising a flavorant dispersed in the mouth-soluble polymer matrix or cellulosic fibers such that the flavorant is released when placed within a mouth of an adult consumer.

12. The oral product of claim 11, wherein the flavorant is selected from the group consisting of licorice, wintergreen, cherry and berry type flavorants, Dramboui, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cinnamon, cardamon, apium graveolents, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Japanese mint, cassia, caraway, cognac, jasmin, chamomile, menthol, ylang ylang, sage, fennel, pimenta, ginger, anise, coriander, coffee, mint oils from a species of the genus Mentha, and combinations thereof.

13. The oral product of one of claim 1, wherein the body is shield shaped.

14. The oral product of claim 13, wherein the body has a diameter of between 5 mm and 25 mm and a thickness of between 1 mm and 10 mm.

15. The oral product of claim 1, wherein the cellulosic fibers are sugar beet fibers, wood pulp fiber, cotton fiber, bran fiber, citrus pulp fiber, grass fiber, willow fiber, and poplar fiber.

16. The oral product of claim 1, wherein the oral product comprises between 0.1 mg and 6 mg nicotine.

17. The oral product of claim 1, wherein the body has a compressibility @ 250 N of less than 95%.

18. The oral product of claim 1, wherein the body has a compressibility @ 250 N of less than 80%.

19. The oral product of claim 1, wherein the body has a compressibility @ 250 N of between 45% and 90%.

20. The oral product of claim 1, wherein the body has a compressibility @ 425 N of less than 99%.

21. The oral product of claim 1, wherein the body has a compressibility @ 425 N of between 60% and 98%.

22. The oral product of claim 1, wherein the body has a percentage of springiness of at least 20%.

23. The oral product of claim 1, wherein the body has a percentage of springiness of at least 70%.

24. The oral product of claim 1, wherein the body has a percentage of springiness of between 75% and 90%.

25. The oral product of claim 1 wherein the oral product is form by:

extruding a mixture comprising the mouth-soluble polymer and the cellulosic fibers; and

dispersing nicotine or derivative thereof within the mouth-soluble polymer during or after the extruding step.

2. An oral product, comprising:

a stick; and

a coating on the stick, the coating consisting of;

a mouth-soluble polymer matrix comprising one or more mouth-soluble polymers in an amount between 40 and 80 weight percent of the coating;

at least 10 weight percent of non-tobacco cellulosic fibers embedded in the mouth-soluble polymer matrix, the non-tobacco cellulosic fibers comprising cellulose, the non-tobacco cellulosic fibers having an average fiber size of less than 200 micrometers; and

nicotine or a derivative thereof dispersed in the mouth-soluble polymer matrix such that the nicotine or derivative thereof is released from the coating when the coating is at least partially received within the oral cavity and exposed to saliva, wherein the cellulosic fibers provide passages in the mouth-soluble polymer matrix to pores retaining the nicotine or derivative thereof, the pores having diameters of between 40 and 60 microns.

26. The oral product of claim 2 wherein the oral product is formed by forming a slurry of the mouth-soluble polymer, the cellulosic fibers, and the nicotine or a derivative thereof;

applying the slurry to the stick; and
