CAROAT
CAROAT
Potassium monopersulfate (KMPS)
CAS#70693-62-8
Potassium peroxymonosulfate – triple salt: 2KHSO5 • KHSO4 • K2SO4
Structural Formula
Description
White, crystalline, odourless, free flowing salt consisting of potassium peroxymonosulfate, potassium hydrogen sulfate and potassium sulfate.
The only stable transportable salt of Caro's acid is its triple salt (theoretical Formula see above).
KMPS undergoes a strongly acid reaction in aqueous solution.
As a result of its high oxidation potential and microbiological effectiveness, it can be used for a large number of different applications.
It has the particular advantage of being highly stable in storage, easy and safe to handle, free from chlorine and of having a high reactivity.

Technical Data Sheet
Application
Denture cleaner: Effective main ingredient in Cleaning tablets for dentures.
Disinfectant: Use for chlorine-free disinfection or purification of swimmingpool water and spas.
Prevention of chlorine acne and eye irritation.
Approved for oxidative drinking water treatment.
Bleaching agent: CAROAT® has a bleaching effect comparable to that of organic peracids; in the TAED/perborate system it is particularly effective at low temperatures.
Biocidal effect: Suitable as an additive to acidic cleaning agents with bleaching and disinfectant effect.
Effluent treatment: Oxidative treatment of problematic effluents; sulfide oxidation, nitrite oxidation and cyanide detoxification (see our technical information).
Plaster additive: Addition of CAROAT® leads to generation of oxygen and improved product characteristics (e.g. thermal insulation, water absorbency, mechanical properties).
Metal treatment: Microetchant: Use for etching printed circuit boards.
Others:
- Textile finishing (shrink proofing of wool)
- Chemical synthesis (production of dioxirane)
- Paper manufacture (repulping, particularly of wet-strength paper).
Storage
CAROAT® must be stored under dry conditions. It has to be protected from direct sunlight and from any other sources of heat.
Standard Packaging: The standard packaging of CAROAT® is 25 kg PE-bag
