Tetrakis(hydroxymethyl)phosphonium chloride (THPC) is an organophosphorus compound with the chemical formula [P(CH2OH)4]Cl. The cation P(CH2OH)4+ is four-coordinate, as is typical for phosphonium salts. THPC has applications as a precursor to fire-retardant materials.
It is used for textile post-treatment, as a flame retardant for plastics and paper products, and also for organic synthesis

Tetrakis(hydroxymethyl)phosphonium sulfate(THPS) THPS is a kind of environmental anti-microbial reagent. It's characterized by its low solidity point and fine stability. It can be reserved for long time and can easily dissolve in water. It's a kind of new environmental pesticide with high efficacy, low toxicity and low rudimental. It can kill germ and aquatic plants. In 1995, the EPA of the United States ratified it with zero toxicity and awarded it with US Green Chemical prize. Net weight 250kg in plastic drum Keep hermetic

[Application] Antimicrobial for Industrial Water Treatment, THPS is a biocide effective against micropest in industrial cooling systems, oil field operations, and paper-making industry. The advantage is it will soon degrade to a nontoxic substance immediately after use. Also it can be applied to fabric coating, obviously improving, flame retarding property.
