Additional information

No experimental data evaluating the biodegradation potential of Glycerides, C16-18 mono-, di- and tri- (CAS No. 91052-54-9) are available. Therefore, data from structurally related category members are used as read-across in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. In two biodegradation screening studies performed with the read-across substances docosanoic acid, ester with 1,2,3-propanetriol (CAS No. 77538-19-3) and Glycerides, C14-18 mono- and di- (CAS No. 67701-33-1), 78% and 69-95% biodegradation after 28 days was observed (respectively). Based on these results, Glycerides, C16-18 mono-, di- and tri- is expected to be readily biodegradable as well and therefore, rapidly biodegraded in both aquatic and terrestrial environments. Thus, in accordance with Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9.2.1.2, 9.2.1.3 and 9.2.1.4, further testing on biodegradation of the substance in water, sediment and soil are not required.
