Description of key information

Water solubility is loading rate dependent_OECD 105/EU Method A.6_20 +/- 0.5 °C_mean TOC concentration: 5.69 x 10E-2 g/L at 0.1 g/L loading rate, 0.386 g/L at 1 g/L loading rate and 1.710 g/L at 10 g/L loading rate, respectively. 
Read-across substance_Phosphoric acid, mono- and di-(C8-C10) ester, compds. with C12 - 14 amine_visual inspection: < 1.7 x 10E-3 g/L at 21.5 +/- 0.5 °C

Key value for chemical safety assessment

Water solubility:
0.057 g/L
at the temperature of:
20 °C

Additional information

As the target substance is a complex UVCB, the flask method according to OECD Guideline 105 / EU Method A.6 was considered as most appropriate method in order to determine the water solubility (Fox, 2013). Based on the chemical nature of the substance, a definitive water solubility result would not be possible. Thus, the loading rate effects based on mean TOC (Total Organic Carbon) concentrations were investigated.

The read-across substance can be considered as slightly miscible in water.
