Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Experimental procedure is technically not feasible. Prediction with KOCWINv2.00: logKoc: 9.33 to 14.06 (two representative structures, respectively)
Key value for chemical safety assessment

Additional information
The determination was not carried out using the HPLC screening method, designed to be compatible with Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001 and Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 as the method was shown not to be applicable.
Therefore, the soil adsorption coefficient of Reaction Products of alcohols, C14-18, C18 unsat., esterified with phosphorus pentoxide and salted with amines, C12-14,-tert-alkyl was determined by the computer program KOCWIN v2.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2013). This tool uses two different models: the Salbjic molecular connectivity (MCI) method with improved correction factors and therefore taken into account more seriously as well as the traditional method which is based on the logarithmic octanol-water partition coefficient, logPow.For the first representative structure of the UVCB substance, the traditional method gives a logKoc of 6.46 L/kg and the MCI method reveals a value of 9.33 L/kg as result. The second structure reveals logKoc values of 10.99 L/kg and 14.06 L/kg concerning the traditional and MCI method, respectively. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
[LogKoc: 9.33]
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).
