Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Adsorption/Desorption
In accordance with column 2 of REACH Annex VIII Nr 9.3.1 column 2, the study does not need to be conducted as the substance has a low potential for absorption (log Kow < 3, see Sect. 4.7) and is readily biodegradable (see Sect. 5.2.1).
Based on a calculated log Koc of 1.1363 (Koc = 13.69). N,N-Dimethylbutylamine is expected to have a high mobility in soil (GUBDH, 2012). This value is used for the calculation of PNECs sediment and soil.
Henry’s Law constant
Henry’s law constant (HLC) of N,N-Dimethylbutylamine at 25°C was estimated by calculation using the group contribution method of Maylan and Howard (1995) (US EPA EPI Suite v4.10, program component HENRYWIN v3.20) (GUBDH, 2012; program).
calculated HLC (25°C) = 31.2 Pa m³/mol. This value is used for the calculation of PNEC soil.
N,N-Dimethylbutylamine is expected to volatilize only to a low degree from water.
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.
