Potassium permanganate

Potassium permanganate (CAS 7722-64-7) is an inorganic oxidising salt supplied under trade names including Cairox, Turco 4338C, and Pure Light E 2, as well as the abbreviation GS-KP. It carries the C.I. designation 77755 and has no assigned E-code, as it is not approved as a food additive.

In water treatment, potassium permanganate oxidises dissolved iron, manganese, and hydrogen sulphide, converting soluble contaminants into filterable precipitates. In textile and leather processing, it acts as a bleaching and oxidising agent to decolourise fibres and remove residual dyes. Pharmaceutical and mining applications rely on its biocidal and oxidising properties for disinfection and ore processing.

Potassium permanganate is available in technical and pharmaceutical grades, with Ph.Eur.-compliant material supplied for healthcare applications. It falls under REACH regulation and requires classification as an oxidising solid. Typical packaging includes fibre drums and multi-wall bags in quantities from 25 kg upward.
