Is Potassium Hydroxide (E525) Halal?

MUIS lists E525 (Potassium Hydroxide) as halal. It is manufactured synthetically from non-animal raw materials. The status applies to the additive itself; the finished product still needs its other ingredients checked.

Potassium hydroxide (caustic potash) is a strong alkali used as an acidity regulator and processing aid, mainly in cocoa processing and as an alternative to sodium hydroxide in low-sodium products.
