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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioaccumulation in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
No study on the bioaccumulation of the test substance in organisms is available. Because of the multi-constituent nature of the substance each test substance component has been examined separately with help of model calculations for logPow. Subsequently, the accumulation potential of the test substance in organisms was derived from the outcomes of the evaluation of its components.
The following logPow values of the uncharged molecules were determined by EpiWin calculations (SRC KOWWIN v2.00):
CAS 104-75-6: logPow = 2.73
CAS 102-71-6: logPow = -2.48
CAS 6975-33-3: logPow = 3.22
For the charged molecules, logD values were calculated using SPARC On-Line Calculator v4.6 which resulted in the following pH-dependent logDs:
|
pH5 |
pH7 |
pH9 |
CAS 104-75-6 |
-1.17 |
-1.03 |
0.42 |
CAS 102-71-6 |
-5.71 |
-3.78 |
-2.85 |
CAS 6975-33-3 |
1.52 |
0.29 |
0.21 |
These results demonstrate that under environmental conditions (pH from 5 to 9), where the three test substance components are mostly present in their charged forms, the potential for bioaccumulation is low for each one of them. Since the test substance is composed mainly of these three constituents, bioaccumulation is not expected for the test substance as well.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
