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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Butylal adsorption/desorption was estimated by KOCWIN v2.00 software to a Koc value of 184.1 L/kg.
Therefore butylal would be moderately mobile in soil.
Key value for chemical safety assessment
- Koc at 20 °C:
- 184.1
Additional information
According to REACH Annex VIII, Point 9.3.3 (Adsorption/desorption screening), the study needs not be conducted if:
- based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient); or
– the substance and its degradation products decompose rapidly.
With a log Kow of 2.75, a study using animals is not justified. Butylal adsorption/desorption was estimated by KOCWIN v2.00 software to a Koc value of 184.1 L/kg. Therefore butylal would be moderately mobile in soil.
