Description of key information

log Koc = 2-7.9 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

Experimental data on the adsorption potential of Stearic acid, monoester with glycerol (CAS 31566-31-1) are not available. Calculated values for the main components using KOCWIN Program (v2.00) indicate that the substance has the potential to adsorb to soil and suspended matter (Gebhardt, 2013). Log Koc values ranging from 2 – 7.9 were calculated for the single substance components. The calculations were based on the molecular conductivity index (MCI). The model has no universally accepted definition of model domain, but since the calculated Kow of single substance components is outside the Kow range of the training set for both models, the results should be taken with caution. Though the calculated values may not be fully reliable a high adsorption potential is indicated.
