Nicotine Pouch Ingredients: What Is Actually in a Zyn, On!, or Velo Pouch?

Nicotine pouches typically contain five categories of ingredients: nicotine (either tobacco-derived and purified or synthetic), plant-based fillers (usually cellulose fibers from pine or eucalyptus), pH adjusters (sodium carbonate or sodium bicarbonate to increase nicotine absorption), flavorings (both natural and artificial), and sweeteners (acesulfame K or sucralose). There is no tobacco leaf in any nicotine pouch — the white pouch material is a food-grade nonwoven fabric. The exact formulation varies by brand, but the basic makeup is similar across the major brands.

The nicotine in most pouches is extracted from tobacco plants, then purified to pharmaceutical grade. This is the same process used to produce nicotine for patches and gum. The purification removes tobacco-specific nitrosamines and other plant compounds, leaving only the nicotine molecule.

Some newer brands use synthetic nicotine (sometimes marketed as tobacco-free nicotine or TFN), which is manufactured in a lab without any tobacco plant involvement. Chemically, the nicotine molecule is identical. The distinction is regulatory and marketing: synthetic nicotine was briefly in a regulatory gray area in the U.S. until the FDA was granted authority over all nicotine products in 2022.

Brands differ in which source they use; the ingredient list on the can or the maker's website is the place to check. Either way, the product delivers the same nicotine molecule.

The bulk of a nicotine pouch is filler material that gives it structure and absorbs moisture. Most brands use plant-derived cellulose fibers — essentially wood pulp processed into a fine powder. A common one is microcrystalline cellulose, the same material used as a binder in pharmaceutical tablets.

The pouch itself — the small fabric bag that holds everything together — is typically made of a food-grade nonwoven material, usually polypropylene or cellulose-based fabric. It is designed to be permeable enough to release nicotine and flavor while containing the powder. The pouch is not meant to dissolve, which is why you spit it out when done.

Some brands add hydroxypropyl cellulose (HPC) as a binder to prevent the powder from clumping and to control the moisture release rate. Others use maltitol or other sugar alcohols both as fillers and mild sweeteners. The filler composition affects the mouthfeel of the pouch — brands with more cellulose tend to feel drier, while those with more maltitol feel slightly softer and moister.

This is probably the most important ingredient category that most people overlook. Nicotine exists in two chemical forms: freebase (unionized) and protonated (ionized, or salt form). Freebase nicotine absorbs through mucous membranes much more efficiently than the salt form. The pH of the environment determines the ratio between these two forms — higher pH means more freebase nicotine and faster absorption.

Nicotine pouches use alkaline compounds — typically sodium carbonate (Na2CO3) or sodium bicarbonate (NaHCO3, baking soda) — to make the inside of the pouch alkaline. At a higher pH, a significant portion of the nicotine converts to freebase form and absorbs rapidly through the oral mucosa. This is the same principle used in traditional Scandinavian snus, which also uses sodium carbonate.

The pH level directly affects the perceived strength of the pouch. Two pouches with the same nicotine content but different pH levels will feel noticeably different — the one with higher pH will hit faster and feel stronger because more nicotine reaches the bloodstream per unit time. That is one reason the number on the can doesn't tell the whole story about how a pouch feels.

The burning or tingling sensation some users feel, especially with stronger pouches, is partly caused by the alkaline pH irritating the oral mucosa, and it may contribute to gum irritation with heavy or prolonged use.

The flavor systems in nicotine pouches are similar to those in food and beverage products. Mint and wintergreen flavors typically use menthol and methyl salicylate, respectively. Fruit flavors use combinations of natural and artificial flavor compounds. Coffee flavors typically use natural coffee extract.

Sweeteners are usually non-caloric, such as acesulfame potassium (Ace-K) or sucralose.

The flavor experience changes over the life of a pouch: the flavor tends to fade before you take the pouch out. If you notice yourself reaching for a fresh pouch when the flavor fades, that's a habit worth tracking if you're trying to cut back.

An ingredient worth flagging: some pouches contain propylene glycol as a humectant (moisture retainer) and flavor carrier. Propylene glycol is also used in many foods, but some people are sensitive to it and may experience gum irritation they attribute to the nicotine or alkalinity when the PG is actually the culprit.
