Description of key information

log Koc 1.8 - 3.4 (KOCWIN v2.00, MCI)

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption behaviour of 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) are available. Using KOCWIN Program (v2.00), log Koc values from 1.8 to 3.4 were calculated for the different constituents, based on molecular connectivity index (MCI) (Blum, 2012). However, all definite values for Sorbitan esters should be taken with caution, since the molecular structure indicates a potential of surface active properties, which may further increase the adsorption potential of the substances.

Based on this information, it can be concluded that the adsorption potential of 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) to soil is moderate.
