Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with Column 2 of Annex VII Section 7.8 and Section 2 of Annex XI of the REACH regulation the test was not performed because the substance decomposes rapidly in aqueous solution (hydrolytically unstable).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.485
- at the temperature of:
- 25 °C
Additional information
Due to the behaviour of the substance in water and aqueous solution (rapid hydrolysis), the test could not be performed. Alternatively, the log Kow of MMDS and its hydrolysis products MDSA and formaldehyde were calculated using EPI Suite (KOWWIN Program (v1.68)):
Calculation of the log Kow of MMDS: estimated value of -0.85
Calculation of the log Kow of MDSA: estimated value of -1.485
Calculation of the log Kow of formaldehyde: estimated value of 0.35
For chemical safety assessment purposes the log Kow value of MDSA (i.e. -1.485) will be considered as key value.
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.
