Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 > 5 (KOCWIN 2.00)

Key value for chemical safety assessment

Additional information

No experimental data evaluating the adsorption potential of Glycerides, mixed C8-10 and succinyl (CAS No. 91744-56-8) are available. Therefore, QSAR estimations using the KOCWIN v2.00 program have been performed instead, resulting in log Koc values ranging from 6.4-20 (MCI method). The estimated log Kow value of this substance (> 10) is outside the Kow range of the training set of the MCI method (-2.11-9.10), and therefore the obtained values should be taken with caution. The definite values may not be fully reliable but indicate a high adsorption potential. According to the Guidance on information requirements and chemical safety assessment, Chapter R7.a (ECHA, 2012), a cut off value of log Kow =3 can be applied to estimate the adsorption potential of a substance. Furthermore, substances with log Kow > 5 are considered as highly adsorptive (Guidance on information requirements and chemical safety assessment, Chapter R7.b, ECHA, 2012). Based on the estimated log Kow (>10) of Glycerides, mixed C8-10 and succinyl, the substance is expected to show a high adsorption potential to solid particles.
