Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 Sorbitan laurate (CAS No. 1338 -39 -2) 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 Sorbitan laurate to soil is moderate.
