Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data for soil sorption are reported in a reliable scientifical study. Soil sorption Kd was 1.5 L/kg, at 20 °C.
The soil sorption coefficient indicates that acetone is mobile in soil and may be transported by soil water.

Key value for chemical safety assessment

Additional information

The result of the key study is supported by two other findings. In an adsorption/desorption study with the clay mineral sodium montmorillonite no adsorption of acetone was observed. Sodium montmorillonite is part of the clay fraction soils. Therefore it can be concluded that acetone does not sorb on clay fractions of soils. In a further study on anaerobic biodegradation of14C labelled acetone in landfill refuse, the soil was intensively extracted after the experiment. The study shows that acetone is able to percolate through landfill refuse caused by rainfall, despite anaerobic biodegradation occurred. Traces of 14C were found in the humin fraction of the refuse, but nature and bonding of these residues were not studied. No physically adsorbed 14C-acetone was found in the CH2Cl2-extracts of the samples percolated with water, and only traces of 14C-acetone were found in the samples that were not percolated by water, indicating the low adsorption potential of 14C-acetone.
