Additional information
The relative density of the read across substance (2-Propenoic acid, C18-22-alkyl esters, a mixture of CAS no 4813-57-4, 48076-38-6 and 18299-85-9) was assessed according to OECD guideline 109 (pycnometer method) and was found to be 0.945 at 20 °C (BASF SE 2013).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
