Description of key information

The HLC of 2.7 mPa m3/mol at 12 C is calculated from the vapour pressure and CMC of C10-13, reaction products with branched nonene, sulphonated, sodium salts. 

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
12 °C

Additional information

Volatilisation of organic compounds from surface waters is generally estimated by the Henry’s law constant. The Henry’s law constant is calculated with EUSES from the ratio of the vapour pressure (Pa) and the CMC (mol/m3). The Henry's Law constant at environmental temperature is 0.0027 Pa.m3/mol at 12 C based on the vapour pressure of 5.8 mPa at 25 C and CMC of 600 g/L. Considering the low HLC, volatilisation at environmental conditions is expected to be negligible.
