25 Kilo Bag Option for Potassium Carbonate

What is Potassium Carbonate?

A soluble, inorganic powder, Potassium Carbonate is a mildly salty and metallic-tasting product commonly supplied to food, beverage and industrial applications throughout the UK and Ireland.

Producing Potassium Carbonate occurs by reacting Potassium Hydroxide and Carbon Dioxide, creating the below reaction:

2KOH + CO2 -> K2CO3 + H2O

Once this solution has reacted fully (Sesquihydrate), it is dried to over 200oC, creating the dry, anhydrous salt used by businesses.

Potassium Carbonate is an additive in soaps and more of an agent to neutralise pH. This neutralising feature makes it useful in foods and drinks. The range includes gingerbread, cocoa powder and oriental dishes such as moon cakes, noodles and more.

Beyond these, mead and wine production also use Potassium Carbonate as a buffering agent due to its stability in the fermentation process. Other applications include an acidity regulator, fire suppressant and feed additive.
