Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption / desorption
The Soil Adsorption Coefficient i.e Koc value of 2-hydroxypropyl octadec-9-enoate was estimated using EPI suite KOCWIN Program (v2.00) program as Koc 11620 L/kg(log Koc= 4.06) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 2-hydroxypropyl octadec-9-enoate has a Strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Additional information
Adsorption / desorption
Three results including different predicted data from validated models and experimental data from authorative database for adsorption (KOC) endpoint of target chemical 2-hydroxypropyl octadec-9-enoate (Cas no. 1330-80-9) were summarized as follows:
First prediction done using EPI suite KOCWIN Program (v2.00) program indicate the estimated adsorption (KOC) for 2-hydroxypropyl octadec-9-enoate is 11620 L/kg(log Koc= 4.06) by means of MCI method at 25 deg.C. This Koc value indicates that the substance 2-hydroxypropyl octadec-9-enoate has a Strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Other predicted model Chemspider - ACD/PhysChem Suite indicate the soil adsorption coefficient i.e Koc value of test substance 2-hydroxypropyl octadec-9-enoate was estimated to be 277348.34 (log koc: 5.44) at pH 5.5 and pH 7.4 and temp.25 deg.C this Koc value at different pH indicates that the substance 2-hydroxypropyl octadec-9-enoate has very strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Both above predicted results of target supported by experimental data of read across chemical Isopropyl Myristate (Cas no. 110-27-0) which suggest using a structure estimation method based on molecular connectivity indices, the Koc of isopropyl myristate can be estimated to be 1200. This estimated Koc value suggests that isopropyl myristate is expected to be immobile in soil.
Thus based on the above information for adsorption endpoint, it can be concluded that the test substance 2-hydroxypropyl octadec-9-enoate (Cas no. 1330-80-9) is expected to be immobile in soil and sediment compartment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
