Abstract

The coating composition of a low ignition propensity cigarette paper according to an exemplary embodiment includes pregelatinized starch, maltodextrin, resistant maltodextrin and ethanol.

First claim

The invention claimed is:

1. A coating composition of a low ignition propensity cigarette paper, comprising:
pregelatinized starch,
maltodextrin,
ethanol, and
water,
wherein the pregelatinized starch, the maltodextrin, the ethanol, and the water are included in an amount of about 5 wt % to about 20 wt %, about 5 wt % to about 40 wt %, about 10 wt % to about 40 wt %, and about 30 wt % to about 80 wt % respectively, based on the coating composition.

2. The coating composition of claim 1 , further comprising:
resistant maltodextrin, inulin, or a combination thereof.

3. The coating composition of claim 2 , further comprising:
oxidized pregelatinized starch.

4. The coating composition of claim 3 , further comprising:
propylene glycol, glycerin, or a combination thereof.

5. The coating composition of claim 4 , further comprising:
D-sorbitol.

6. The coating composition of claim 1 , further comprising:
oxidized pregelatinized starch.

7. The coating composition of claim 6 , further comprising:
propylene glycol, glycerin, or a combination thereof.

8. The coating composition of claim 7 , further comprising:
D-sorbitol.

9. The coating composition of claim 1 , wherein:
the coating composition consists essentially of the pregelatinized starch, the maltodextrin, the ethanol, and the water.

10. The coating composition of claim 9 , wherein:
a weight ratio of the pregelatinized starch and the maltodextrin is about 1:0.5 to about 1:8.0.

11. A cigarette, comprising:
a cigarette column portion, and
a low ignition propensity cigarette paper surrounding the cigarette column portion and comprising a coating portion provided by a coating composition,
wherein the coating comprises pregelatinized starch, maltodextrin, and ethanol,
wherein the pregelatinized starch, the maltodextrin, and the ethanol are included in an amount of about 5 wt % to about 20 wt %, about 5 wt % to about 40 wt %, and about 10 wt % to about 40 wt %, respectively, based on the coating composition.

12. The cigarette of claim 11 , wherein:
the coating portion further comprises resistant maltodextrin, inulin or a combination thereof.

13. The cigarette of claim 12 , wherein:
the coating portion further comprises oxidized pregelatinized starch.

14. The cigarette of claim 13 , wherein:
the coating portion further comprises D-sorbitol.

15. The cigarette of claim 11 , wherein:
the coating portion further comprises oxidized pregelatinized starch.

16. The cigarette of claim 15 , wherein:
the coating portion further comprises D-sorbitol.

17. The cigarette of claim 11 , further comprising:
a cigarette filter portion.

18. The cigarette of claim 17 , wherein:
the cigarette filter portion comprises at least one filter member.

19. The cigarette of claim 18 , wherein:
the cigarette filter portion comprises at least one of an adsorbent or a flavoring agent.
