Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- 2-ethylhexanol and pentane-2,4-dione are two main hydrolysis prodcuts of the target substance. Properties of the the two substance are used for read-across.

- GLP compliance:
- not specified
- Type of method:
- batch equilibrium method

- Key result
- Type:
- Koc
- Value:
- ca. 105 L/kg

Description of key information
Key value for chemical safety assessment
- Koc at 20 °C:
- 105
Additional information
Testing is scientifically unjustified as this substance is hydrolytically unstable (half-life less than 30 minutes). The hydrolysis products were identified to be 2-ethylhexanol and pentane-2,4-dione. The Koc value of more hydrophobic component, 2-ethylhexanol (judged from its octanol-water partition coefficient Kow), was used for CSA.
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.
