Potassium Acetate (CAS 127-08-2, E261) with min. 99.0% purity, supplied wholesale by Zyntex. Used in low-corrosion runway de-icing fluids, kitchen fire extinguishers, food and laboratory buffers. CoA and SDS with every lot.
Potassium acetate (CH3COOK) is a white, deliquescent crystalline powder that is very soluble in water. It readily absorbs moisture from the air, so it is supplied in sealed packaging. In food, it is approved as a preservative and acidity regulator under E number E261.
One of the largest uses of it is in de-icing fluids for airport runways and roads. Compared with chloride salts, it is less corrosive to metals and concrete and is biodegradable, which is why many airports prefer it. It is also used in wet-chemical fire extinguishers for kitchen fires and as a component of drilling fluids.
In laboratories, it is a common buffer and reagent in molecular biology, for example in DNA extraction and precipitation. It belongs to the same family as Calcium acetate and Zinc acetate, and is sometimes compared with Potassium Carbonate when a potassium source is needed in a formulation.

⚠️ Safety & Handling: Low hazard, but dust may irritate the eyes and respiratory tract; avoid creating dust and wear eye protection and gloves. It is strongly hygroscopic, so store it in tightly closed packaging in a cool, dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Why is potassium acetate used for runway de-icing?
It melts ice effectively at low temperatures while being less corrosive to aircraft metals and concrete than chloride salts, and it is biodegradable.
How should potassium acetate be stored?
Keep it in sealed packaging in a dry place. It absorbs moisture from the air and can dissolve if exposed to humidity.
