Key value for chemical safety assessment

Additional information

The log Kow was determined to be 4.4 (OECD 117, weighted average), which is below the screening criteria indicated in Annex XIII (B fulfilled with log Kow of ≥ 4.5). Since 4.4 is close to the screening criteria, the EPA PBT Profiler was run on the hydrolytic and break down products of the registered substance to determine an estimation of BCF. The estimated BCF for 9 -Octadecenoic acid (Z)-,monoester with 1,2,3 -propanetriol (CAS RN 25496 -72 -4) is 330; 1,2,3 -propanetriol (CAS RN 56 -81 -5) is 3.2; and 9 -Octadecenoic acid (Z)- (CAS RN 112 -80 -1) is 56. Therefore, the registered UVCB substance is not considered bioaccumulative.
