London chemist Henry Bollmann Condy had an interest in disinfectants; he found that fusing pyrolusite with sodium hydroxide (NaOH) and dissolving it in water produced a solution with disinfectant properties. He patented this solution, and marketed it as 'Condy's Fluid'.
Condy had an interest in disinfectants and marketed products such as "ozonised water". He developed and patented "Condy's fluid" in 1857.
Condy’s fluid was a disinfectant solution of alkali and permanganates that could be taken internally or used externally. It had various indications including the treatment and prevention of Scarlet Fever .
Although effective, the solution was not very stable. This was overcome by using potassium hydroxide (KOH) rather than NaOH. This was more stable, and had the advantage of easy conversion to the equally effective potassium permanganate crystals. This crystalline material was known as 'Condy's crystals' or 'Condy's powder'
A more stable crystalline version of Condy's fluid was subsequently developed and marketed as Condy's Crystals or Cond's powder. The fluid and crystals were both manufactured at the company’s works in Battersea between 1867 and 1897.
Robert Koch described a disinfectant test in 1881
