Potassium permanganate, KMnO4, is also called "permanganate of potash" or "Condy's crystals." "Potash" is a term that is commonly used in the naming of potassium compounds, and Henry Bollmann Condy marketed the crystallized substance as a disinfectant product.

Potassium permanganate is the chemical compound KMnO4. In this salt, manganese is in the +7 oxidation state. The salt is also known as "permanganate of potash" and "Condy's crystals". The permanganate ion is a strong oxidizing agent. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals.It has a sweet taste and is odourless.

In 1659 a German chemist, J.R. Glauber, fused a mixture of the mineral pyrolusite and potassium carbonate to obtain a material that, when dissolved in water, gave a green solution (sodium manganate) which slowly changed colour to violet (potassium permanganate) and then finally red. This report represents the first description of the production of potassium permanganate.

Just under 200 years later a Londoner named Henry Bollmann Condy trained as a chemist. He had an interest in disinfectants and marketed a number of products including ozonised water. He found that when he fused pyrolusite with NaOH and dissolved the product in water it gave a solution that had good disinfectant properties. He patented this solution, and marketed it as Condy's Fluid. The problem was that the solution, although it was quite effective, it was not very stable. This difficulty was overcome by using KOH rather than NaOH. This gave a more stable material, which had the added advantage of being easily converted to the equally effective potassium permanganate crystals. This crystalline material was known as Condy’s crystals or Condy’s powder. Potassium permanganate was comparatively easy to manufacture so Condy was subsequently forced to spend considerable time in litigation in order to stop competitors from marketing products similar to Condy's Fluid or Condy's Crystals.
