Frequently Asked Questions
Is Chemifin potassium hydroxide food grade?
Yes. Chemifin supplies potassium hydroxide (KOH) flakes 90% food grade, suitable for food applications, as well as for technical uses.
What does KOH do in food?
In food, KOH is used mainly as a pH regulator and, in some formulations, as a stabiliser, within the applicable regulatory limits.
What is the difference between KOH and NaOH?
Both are strong alkalis. KOH (potassium hydroxide) is preferred for liquid soap and applications that need potassium salts, while NaOH (caustic soda) is more common for bar soap and general industrial use. For a milder alkali, see our Potassium Carbonate page.
