Description and Uses

Tetrakis(hydroxymethyl)phosphonium sulfate (THPS) is an organophosphorus compound. It is used as a precursor in the flame retardant manufacturing process, a biocide in water systems, and a tanning agent in the leather industry. THPS is a safe aqueous solution with antimicrobial properties that is significantly less toxic, effective at lower concentrations, and more biodegradable than other traditional biocides.
