Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Octanol-water partition coefficient (EDTMP-xCaNa): -4.1

Key value for chemical safety assessment

Log Kow (Log Pow):

Additional information

The log Kow of EDTMP-xCaNa was read across from its parent acid. A log Kow value of -4.1at 100 ppm and 1000 ppm were reported in a reliable study conducted according to generally accepted scientific principles comparable to an appropriate test guideline. Method has been adequately described in the report. The result is considered to be reliable and has been assigned as key study. This is supported by a predicted value of -4± 1 using a relevant estimation method. Similarly, a log Kow of <<0 was determined for EDTMP-xCaNa using fragment method.

A log Kow value of -4.1 was reported for the parent acid in available secondary sources, full details are not available and the reliability is unassignable. The resuts are in agreement with the key study. Also, value of <0 were reported in available secondary sources for EDTMP-xCaNa.
