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 fundamental architecture is the same across Zyn, On!, Velo, Rogue, and other major products.

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 — your body cannot tell the difference. 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.

Zyn uses tobacco-derived nicotine. On! also uses tobacco-derived nicotine. Velo (made by British American Tobacco) uses tobacco-derived nicotine in most markets. Some smaller brands like Lucy use synthetic nicotine. For the consumer, the practical difference is negligible — the end product is the same molecule at the same purity level.

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. Zyn's primary filler is microcrystalline cellulose, the same material used as a binder in pharmaceutical tablets. On! uses a similar cellulose base.

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 raise the pH inside the pouch to roughly 8-9. At this 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. This is why some 3mg pouches feel surprisingly strong while some 6mg pouches feel mild. If you are comparing brands and the strength does not match the label, pH adjustment differences are almost certainly the reason.

The burning or tingling sensation some users feel, especially with stronger pouches, is partly caused by the alkaline pH irritating the oral mucosa. This is not dangerous in the short term but 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 are by far the most popular — they 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 almost always non-caloric: acesulfame potassium (Ace-K) is the most common, sometimes combined with sucralose. Some brands use xylitol, which doubles as a sweetener and has mild antibacterial properties that may help offset the oral pH disruption from the alkaline agents.

The flavor experience changes over the life of a pouch. Most of the flavor releases in the first 5-10 minutes as saliva dissolves the surface coating. The nicotine release continues for 20-45 minutes depending on the product, which is why long sessions leave you with a nicotine buzz but muted flavor. This mismatch is worth understanding if you are trying to reduce usage — the flavor reward fades much faster than the nicotine delivery, so chasing the flavor leads to higher overall consumption.

An ingredient worth flagging: some pouches contain propylene glycol as a humectant (moisture retainer) and flavor carrier. Propylene glycol is generally recognized as safe (GRAS) by the FDA for food use, 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.
