| Hazard Information | Back Directory | [General Description]
Clear colorless viscous liquid. | [Reactivity Profile]
TETRAKIS(HYDROXYMETHYL)PHOSPHONIUM SULFATE(55566-30-8) is incompatible with oxidizing materials and alkalis. | [Air & Water Reactions]
Water soluble. | [Fire Hazard]
This chemical is probably combustible. | [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.
| [Flammability and Explosibility]
Nonflammable | [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
