Potassium peroxymonosulfate

Potassium peroxymonosulfate (CAS 37222-66-5), also known as potassium caroate or KMPS, is an active oxygen-releasing compound supplied commercially as a triple salt. It functions as a non-chlorine oxidizer across disinfection, bleaching, and surface activation applications.

Buyers source it where chlorine-free oxidation is required without sacrificing performance. In water treatment, KMPS serves as a shock oxidizer for swimming pools and aquaculture systems, breaking down organic contaminants.

It is highly effective at controlling biofilm without raising chlorine levels. Personal care formulators use it as the active oxidant in hair color activators and denture cleaning tablets, where controlled peroxide release is critical.

This stability is essential for product shelf life and consumer safety. Pulp and paper producers apply it for bleaching and brightness retention in chlorine-free processing lines to meet environmental standards.

In textile and leather finishing, it functions as a pre-treatment oxidant to improve dye uptake and surface uniformity. This ensures consistent color application and high-quality finishes across various industrial materials.

Potassium monopersulfate is supplied as a white granular or powder solid. Standard commercial grades include technical and pool/spa grades, with active oxygen content typically specified at around 4.5% for most uses.

Industrial and specialty formulation grades are available for personal care and water treatment end uses. These grades ensure the material meets specific purity requirements for sensitive manufacturing environments and applications.
