Peroxymonosulfuric Acid

Dipotassium peroxymonosulfate (CAS 10361-76-9), also known as potassium peroxymonosulfate or K2SO5, is the potassium salt form of peroxymonosulfuric acid used commercially as a non-chlorine oxidizing agent.

Where is Peroxymonosulfuric Acid used?

• Water treatment: shock oxidizer for swimming pools and aquaculture systems
• Personal care: hair bleaching and color-preparation products, where controlled oxidation lifts pigment
• Pulp and paper: bleaching cellulose fiber, achieving target brightness levels while limiting fiber degradation
• Textile and leather processing: pre-treatment oxidant that prepares substrates for dyeing
• It eliminates organic contaminants and pathogens without chlorine interference.

Commercial specifications

• Active oxygen concentrations of approximately 4.5–5% in standard commercial grades
• Packaging from small retail units to bulk industrial quantities
