Potassium peroxymonosulfate sulfate

CAS: 70693-62-8

Overview

Potassium peroxymonosulfate sulfate (CAS 70693-62-8 ), commonly abbreviated as KMPS, is a stable, non-chlorine oxidizing compound supplied as a triple salt. It delivers controlled oxidation, bleaching, and biocidal action across a broad range of industrial and consumer applications.

In water treatment, KMPS functions as a disinfectant and algaecide for swimming pools and industrial water systems. It offers effective microbial control without the handling concerns associated with chlorine-based alternatives.

Personal care formulators incorporate it into hair color products and oxidative treatments where precise, controlled bleaching is required. Pulp and paper producers use it as a bleaching agent to brighten fibers while minimizing fiber degradation.

In textile and leather processing, KMPS supports fabric desizing, surface oxidation, and preparation steps. These processes improve dye uptake and finish quality across various materials and industrial textile applications.

Potassium peroxymonosulfate sulfate is supplied as a white, free-flowing granular powder, the standard commercial form for industrial and formulation use. It is available in technical grade for industrial processes.

Higher-purity grades are also available, suited to personal care and water treatment applications. Packaging typically ranges from small drums to bulk quantities, depending on application volume requirements.
