Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Aluminum trioctadecanoate was estimated using EPI suite KOCWIN Program (v2.00) as Koc 10000000000 L/kg (log Koc = 10) by means of MCI method at 25 deg.C. This Koc value indicates that the substance Aluminum trioctadecanoate has a very strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Additional information
Adsorption / desorption:
Two studies including predicted data from validated model and experimental results from authorative data source for adsorption (KOC) endpoint of test substance Aluminum trioctadecanoate (Cas no. 637-12-7) with relevant read across which is structurally similar to target were summarized as follows:
First study from EPI suite KOCWIN Program (v2.00) model indicate the estimated the Soil Adsorption Coefficient i.e Koc value of Aluminum trioctadecanoate was estimated as Koc 10000000000 L/kg (log Koc = 10) by means of MCI method at 25 deg.C. This Koc value indicates that the substance Aluminum trioctadecanoate has a very strong sorption to soil and sediment and therefore have negligible migration potential to groundwater.
Above target prediction supported by experimental result of read across chemical Dibutyltin dilaurate (Cas no. 77-58-7) which suggest the chemical Dibutyltin dilaurate is expected to hydrolyze in water forming the cation, dibutyltin and Cations generally adsorb to organic carbon and clay; therefore, dibutyltin may be expected to have limited mobility in soil (i.e immobile in soil) whereas in sediment compartment distribution constants obtained for adsorption of dibutyltin to sediment of 700-26,000 l/kg which also indicate the substance is immobile in sediment also.
Thus both available result for adsorption (KOC) gives the common conclusion as target substance Aluminum trioctadecanoate (Cas no. 637-12-7) is expected to immobile in soil and sediment compartment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
