Additional information

Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, tri- and tetraesters with pentaerythritol is considered to be readily biodegradable according to the OECD criteria based on the result from two suitable read-across substances. The substance is thus expected to be rapidly degraded by microorganisms in the aquatic and terrestrial environments as well, and therefore in accordance with Regulation (EC) No 1907/2006, Annex IX, column 2, 9.2.1.2. - 9.2.1.4., further simulation tests for water and sediment or soil biodegradation are not necessary.
