Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The water solubility of the substance fatty acids, C6 -18, triesters with trimethylolpropane (CAS 91050 -88 -3) was determined according to OECD Guideline 105.

Supporting data from a weight of evidence show that the solubility decreases with increasing chain length of the fatty acid chains. The solubility of the substance is variable due to its UVCB nature. The short chain components lead to a higher solubility than the longer chain components. Therefore the maxium value of 0.407 mg/L obtained in the test is given as worst case value.
