Any other information on results incl. tables
19 of the 28 (68%) possible structures has a calculated partition coefficient value of less than 3.
Log Kow calculated values are all less than 4 for every possible component.
Each substance is of molecular weight > 700 units, the current “cut-off” limit of molecular size for which substances are anticipated to bioaccumulate. (This does not take account of the proposed revised limit of 1000 currently under consideration).
Applicant's summary and conclusion
- Conclusions:
- Each component therefore is NOT anticipated to be potentially bioaccumulative, and by proxy, the substance as a whole is considered to be not bioaccumulative based on the considerations of GHS (and CLP).
- Executive summary:
Taking into consideration all of the above guidance and information, the following can be concluded:
1) Log Kow calculated values are all less than 4 for every possible component.
2) Each substance is of molecular weight > 700 units, the current “cut-off” limit of molecular size for which substances are anticipated to bioaccumulate. (This does not take account of the proposed revised limit of 1000 currently under consideration).
3) The above indicates that the substance does not have the potential for bioaccumulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
