Description of key information

Technical substance (65-68%): clear colourless to yellow liquid aqueous solution. Drying results in a highly viscous yellowish liquid. 

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

Additional information

Tetrakis(hydroxymethyl) phosphonium chloride, oligomeric reaction products with urea is never manufactured/imported or used in dried form. This dried form has been produced only for the performance of tests on the intrinsic physico-chemical properties of the substance. The technical product on the market is only available as aqueous solution.

The dried form (water content (Karl-Fischer): 0.5%) is apparently a yellowish viscous liquid with a glass transition temperature below minus 20°C.
