What Is Synthetic Nicotine?
Synthetic nicotine turns up on e-liquid labels as TFN or tobacco-free nicotine, and the name causes a fair amount of confusion. This is a plain explanation of what it is, how it differs from the nicotine used in most e-liquid, and what the label actually tells you.
You must be 18 or over to buy any nicotine product.
The same molecule, two different sources
Nicotine is a single chemical compound. It can be obtained in two ways.
Tobacco-derived nicotine is extracted from the tobacco plant and then purified. This is what the overwhelming majority of e-liquid uses, including most of what we stock.
Synthetic nicotine is built in a laboratory from precursor chemicals, with no tobacco plant involved at any stage. The finished molecule is nicotine either way — the difference is how it was obtained, not what it is.
Where the two actually differ
Trace plant compounds
Extraction from a leaf carries small amounts of other plant material through with it. Purification removes most of this, but tobacco-derived nicotine often retains a faint colour and a slight smell. That is why some e-liquids darken over time.
Synthetic nicotine is typically clear, odourless and neutral-tasting, because there was never any plant material present. In practice this means it interferes less with the flavourings in the bottle — a taste consideration, not a health one.
Isomers, the part most articles skip
Nicotine exists in two mirror-image forms, S-nicotine and R-nicotine. Nicotine from tobacco is almost entirely S-nicotine.
Laboratory synthesis produces both forms unless the manufacturer separates them, which adds cost. Some synthetic nicotine is therefore a mix of the two rather than pure S-nicotine. Where a producer has done the separation properly, the result is chemically indistinguishable from the tobacco-derived version.
This is worth knowing because two products can both be labelled synthetic nicotine and not be the same thing.
Why manufacturers use it
Supply. Synthesis does not depend on a tobacco harvest, so production is not tied to crop yields or agricultural supply chains.
Consistency. A synthesised batch varies less than an extracted one, which matters to manufacturers producing at volume.
Classification. Some regulators define tobacco products by whether the nicotine originated in a tobacco plant, so synthetic nicotine has at times been treated differently. How any particular market classifies it is a matter for the authorities there, and the position has changed more than once.
What the label tells you
If a bottle says TFN or tobacco-free nicotine, it is telling you the source of the nicotine. It is not telling you the strength, the PG/VG ratio, or anything else about the liquid — those are listed separately and matter far more to how the e-liquid performs in your device.
Strength is labelled identically either way. A 20mg synthetic nicotine salt and a 20mg tobacco-derived nicotine salt are labelled the same because they contain the same amount of the same compound.
Choosing e-liquid
For most people the source of the nicotine is not the deciding factor. Strength, PG/VG ratio and flavour all have a far larger effect on whether you get on with a liquid.
