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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption potential to soil or sediment is low. The mean logKoc is 1.05, calculated by 2 QSAR methods.
Key value for chemical safety assessment
- Koc at 20 °C:
- 11.2
Additional information
The partition coefficients of diacetone acrylamide is low, i.e. log Pow = 0.321, see Chapter 4.7. Diacetone acrylamide is inherently biodegradable. A relevant adsorption of diacetone acrylamide to soil is therefore not expected and a waiving of the study is justified.
Applying additionally a recognised QSAR models it was calculated that the log Koc of diacetone acrylamide is low. The geometric mean of the 2 available Koc was calculated according to the ECHA Guidance Documents on Info Requirements, R.7.1.15.3 to logKoc = 1.05, corresponding to Koc = 11.2.
The adsorption potential to soil or sediment is therefore considered to be low.
[LogKoc: 1.05]
