Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Experimental data on the biodegradability of of Fatty acids, C18-unsatd., dimers, reaction products with fatty acids, C14-18 and C16-18-unsatd. and propylidynemethanol (CAS 162353-70-0) are not available. The assessment of ready biodegradation is based on read across to the analogue substances C18 Fatty acid, dimers, mixed ester with oleic acid and trimethylolpropane (CAS 147256-33-5) and Fatty acids, C16-18 and C18-unsatd., triesters with trimethylolpropane (CAS 68002-78-8). Based on the ready biodegradability of both source substances in water a rapid degradation of the target substance in aquatic and terrestrial environments is expected. Thus, in accordance with Regulation (EC) No. 1907/2006, column 2, -, further simulation tests on biodegradability in water and sediment or soil are not necessary.
