  • Patent number: 10744476
    Abstract: Provided is a method for cooling wax after coextrusion to create wax capsules. The method includes immersing a concentric nozzle of a coextruder in a container of heated alcohol. The container of heated alcohol sits in a water-ice bath to create a temperature gradient. A core material having a wax coating is extruded through a concentric nozzle to form a capsule. The capsule enters the container of hot alcohol where the wax coating is solidified. In an embodiment, the method is a continuous method including a capsule and solvent transfer system.

  • Publication number: 20190328032
    Abstract: 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.
