Description of key information

The water solubilities of the rosin ester substances range from <0.22 mg/L to <32.3 mg/L.

Resin acids and rosin acids, polymerized, esters with glycerol are complex UVCB with components of low or varying water solubilities. As solubility results are expressed as total organic carbon they cannot be directly compared against the solubility categories.

The solubility of resin acids and rosin acids, polymerized, esters with glycerol was measured at two loading rates, 1 and 10 g/L, and the results expressed as total organic carbon (TOC). At a loading rate of 10 g/L TOC was measured as ≤0.00124 g/L and at a loading rate of 1 g/L TOC was measured as ≤0.000879 g/L. The results show that water solubility is loading rate dependent and therefore could be higher than ≤0.00124 g/L at higher loading rates.


Key value for chemical safety assessment

Additional information

One GLP-compliant study, conducted according to OECD Method 105, was provided for Resin acids and Rosin acids, polymerized, esters with glycerol (Harlan Laboratories Ltd., 2013a).
