Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is waived, since the log KOW is considered to be in the range of -0.094 and 0.52 for the individual substructures of the registered substance.

Nevertheless, for deviation of PNEC sediment and soil a log KOC is calculated for the individual substructures using KOC win vs. 2.0 by entering a user presented log KOW.

The most critical log KOC for the derivation of PNECs is the deviated log KOC for Tridecyl-methyl-ammonium chlorid (3xC10). Therefore the respective value is used for the log KOC.

for substructure Methyl-trioctyl-ammonium chlorid (3x C8) the log KOc was deviated to be: 1.12 based on log KOW 0.52

for substructure Decyl-methyl-dioctyl-ammonium chlorid (1xC10;2x C8) the log KOc was deviated to be: 1.05 based on log KOW 0.32

for substructure Didecyl-methyl-octyl-ammonium chlorid (2xC10;1x C8) the log KOc was deviated to be: 0.90 based on log KOW 0.12

for substructure Tridecyl-methyl-ammonium chlorid (3xC10) the log KOc was deviated to be: 0.78 based on log KOW -0.094
