The nicotine pouch is made from organic cellulose compounds that create a non-woven fleece and its thickness helps to determine the nicotine release dynamics. The pouch serves as a container for the nicotine-containing substrate.
The nicotine is a pharmaceutical grade nicotine, extracted from tobacco plants.
The binder/filler helps determine the speed of nicotine release, as well as the characteristics of the physical feeling of the pouch inside the mouth. It consists of three parts:
- The microcrystalline cellulose white powder that absorbs the nicotine
- The gum
- The hydrophilic solvent for stabilizing the level of humidity
If the pH level is too neutral, then nicotine won’t transfer across the mucosa. Anything above 9.1 becomes too basic and can be an oral irritant, which is why existing industry standards set that upper limit. Sodium carbonate or bicarbonate is commonly used to regulate the pH.
The substrate includes E-numbered food-grade flavors, with most nicotine pouches having a mint flavor. PMI does not commercialize pouches with candy flavors for example, which may appeal to a younger audience.
