Caustic Potash Flakes 90% Food Grade E525 - CAS 1310-58-3

Caustic Potash Flakes 90% Food Grade E525 - CAS 1310-58-3

Caustic potash, or potassium hydroxide (molecular formula KOH), is a corrosive alkaline agent known as a strong base. It is a chemical reagent widely used in chemistry. It can be sold in liquid or solid form (flakes or powder). The term potash is often incorrectly used to refer to a source of potassium (e.g. potassium chloride salt KCl, carbonate K2CO3...). It is produced by electrolysis of aqueous solutions of potassium salts (notably KCl). The main use is the manufacture of potassium carbonate by carbonation of potash.

We offer caustic potash (potassium hydroxide) in 25 kg bags, in the form of soluble flakes, exclusively for professional use.

This product is available in technical grade and food grade. Contact us for the latter option.

Do not confuse this product with caustic soda, potassium lye, or potassium carbonate.
