Tetrakis(hydroxymethyl)phosphonium sulfate Usage And Synthesis

Description

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.

General Description

Clear colorless viscous liquid.

Air & Water Reactions

Water soluble.

Reactivity Profile

Tetrakis(hydroxymethyl)phosphonium sulfate is incompatible with oxidizing materials and alkalis.

Fire Hazard

Tetrakis(hydroxymethyl)phosphonium sulfate is probably combustible.

Flammability and Explosibility

Non flammable

Advantages

Advantage of the wet white tanned leathers, using THPS offers:
a light color and pastel shades
They can reach shrink temperatures of at least 70 grad C
High softness
Good lightness
Feeling of naturalness
Pleasant to the touch
Beauty that lasts for a long time
Can be burned without the risk of hexavalent chromium formation
