Additional information

The water solubility of the substance was determined by the flask method according to the OECD Guideline 105 / EU A.6.

In addition for the single components the water solubility was calculated with (Q)SAR (WSKOW v1.42). These calculation show a very low solubility for all components at 25 °C. As expected the smallest component (TMP triester with 2 -EHA) shows the highest solubility of 0.000000752 mg/L at 25 °C.

Therefore it is concluded that the components of the substance Fatty acids, C14 -18 and C16 -18 -unsatd., mixed esters with castor oil, castor oil fatty acids, 2 -ethylhexanoic acid and 2,2 -bis(hydroxymethyl)-1 -butanol have a water solubility of <1 mg/L.

Other components of minor concentration (free fatty acids) may contribute to the solubility of <10 mg/L.
