Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

An experimental study and a calculation have been performed in order to try and determine the water solubility of CAS 94581-15-4 resin and rosin acids, fumarated, esters with pentaerythritol. The experimental value is <1 mg/L (considered 'slightly soluble'). The calculated value is 3.3 mg/L. As the calculated value is based on a simplified structure the experimental value is nominated as the  'key value'.

Key value for chemical safety assessment

Water solubility:
1 mg/L
at the temperature of:
20 °C

Additional information

CAS 94581 -15 -4 is the ester of chemically modified UVCB. 'Pure' is therefore a difficult concept in the face of the variable composition. The experimental value of <0.001 g/L is, at most, 'slightly soluble'. The calculated value is 3.3343 mg/L ('slightly soluble'), but is likely to refer to a more water soluble entity than those present in the substance. The value of <1 mg/L is used as the 'key value'.
