Abstract

Provided is a nicotine pouch filler including nicotine, a release control excipient, a binder, a pH adjuster, and a flavoring agent, in which a content of the binder is 6 to 10 wt % with respect to a weight of total solid contents of the nicotine pouch filler.

First claim

What is claimed is:

1 . A nicotine pouch filler comprising:
nicotine; a release control excipient; a binder; a pH adjuster; and a flavoring agent, wherein a content of the binder is 6 to 10 wt % with respect to a weight of total solid contents of the nicotine pouch filler.

2 . The nicotine pouch filler of claim 1 , wherein the binder comprises at least one or more selected from a group consisting of Povidone K-25, hydroxypropyl cellulose, low-substituted hydroxypropyl cellulose, hydroxypropylmethyl cellulose (HPMC), and carboxymethylcellulose (CMC).

3 . The nicotine pouch filler of claim 1 , wherein
the nicotine comprises nicotine salt, and the nicotine salt comprises at least one or more selected from a group consisting of nicotine salt benzoate, nicotine salt tartrate, nicotine salt malate, and nicotine salt salicylate.

4 . The nicotine pouch filler of claim 1 , wherein the release control excipient comprises one or more selected from a group consisting of cellulose and sugar alcohol.

10 . The nicotine pouch filler of claim 1 , wherein the nicotine pouch filler has nicotine elution performance of 20% or more within 8 minutes, and nicotine elution performance of 70% or more within 30 minutes.

11 . A nicotine pouch comprising:
a nicotine pouch filler; and a packaging material, wherein the nicotine pouch filler comprises:
nicotine;
a release control excipient;
a binder;
a pH adjuster; and
a flavoring agent, and
wherein a content of the binder is 6 to 10 wt % with respect to a weight of total solid contents of the nicotine pouch filler.

12 . A method of preparing a nicotine pouch filler, the method comprising:
step S 1 of mixing at least one or more selected from a group consisting of nicotine, a release control excipient, a binder, a pH adjuster, and a flavoring agent; step S 2 of spraying a solvent; and step S 3 of performing granulation, wherein, in step S 1 , a content of the binder is 6 to 10 wt % with respect to a weight of total solid contents of the nicotine pouch filler.
