Patent number: 11944115Abstract: This document provides methods and systems for stabilizing nicotine and incorporating nicotine into one or more oral products. This document also provides oral products. Nicotine can be stabilized by mixing liquid nicotine with cellulosic fiber such that the liquid nicotine absorbs into pores of the cellulosic fiber to form a cellulosic fiber-nicotine mixture. In some cases, a cellulosic fiber-nicotine mixture can be combined with one or more binders and molded into an oral product.Type: GrantFiled: July 20, 2021Date of Patent: April 2, 2024Assignee: Altria Client Services LLCInventors: Feng Gao, Shuzhong Zhuang, Diane L. Gee
