| | 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
