WS-23
WS-23 is a synthetic cooling agent with generally little flavour of its own, used to create a distinct cold sensation in flavour formulations. It acts through sensory cold receptors and does not technically refrigerate the coil or aerosol.
01
Classification
WS-23 is a constituent of e-liquids with a specific job there – as a carrier, flavour vehicle, sweetener or stabiliser, for example. Its proportion and purity determine how the liquid behaves in the device and in the aerosol. A common error is to treat WS-23 as a single product property, even though the term bundles a whole group of characteristics.
02
Practical relevance
On the label, WS-23 usually appears as a single line in the ingredient list, even though its proportion shapes the entire experience. Anyone investigating intolerances or flavour problems starts exactly here. In practical terms: WS-23 becomes relevant the moment a product is replaced, upgraded or repaired.
03
Handling it safely
The fact that WS-23 occurs in food does not make it harmless when inhaled – the routes of exposure differ fundamentally. With known allergies or irritant reactions, the full ingredient list of the specific product is what matters. Note any conspicuous changes to WS-23 with a date; a recurring pattern carries far more weight in a complaint than a one-off observation.

Not to be confused with
The line between WS-23, Flavour concentrate and Citric acid runs not through the form factor but through what each one measures, regulates or names. Once the three terms are cleanly separated, datasheets and product pages read much faster and lead to fewer mistaken purchases.

Frequently asked questions
- What exactly does WS-23 mean?
- WS-23 is filed under Liquids & ingredients in this glossary. What matters is not the word's origin but the technical property or rule behind it – and that is always stated on the specific product.
- What really matters with WS-23?
- What matters most with WS-23 is the combination: device, consumable and liquid have to match. Individually good figures do not help if one element is out of line.
- What is the difference between WS-23 and Acetoin?
- The two overlap but are not identical: WS-23 answers a different question from Acetoin. On a specific product both specifications can apply at the same time.
