Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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, Me esters are complex UVCBs 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, Me esters 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 ≤0.011 g/L and at a loading rate of 1 g/L TOC was measured as ≤0.0031 g/L. The results show that the water solubility is loading rate dependant and therefore could be higher than ≤0.011 g/L at higher loading rates.

Key value for chemical safety assessment

Additional information

A GLP-compliant study, conducted according to OECD 105 Method (flask method), was provided (Harlan Laboratories Ltd., 2013a), which contains water solubility results for Resin acids and rosin acids, Me esters.
