Additional information

Based on a ready biodegradation studies conducted with the read-across substances Sorbitan stearate (CAS No. 1338-41-6) and Sorbitan oleate (CAS No. 1338-43-8), the substance Reaction products resulting from the esterification of Sorbitol with C8-18 (even) and C18unsaturated fatty acids in the ratio 1:1 (EC 931-434-7) is considered readily biodegradable. The substance is thus expected to be rapidly degraded by microorganisms in both the aquatic and terrestrial environments, therefore in accordance with Regulation (EC) No. 1907/2006, 9.2.1.2 – 9.2.1.4, further simulation testing for water and sediment or soil biodegradation is not necessary.
