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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Stability
Hydrolysis
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, Section 9.2.2.1, a study on hydrolysis does not need to be conducted if the substance is readily biodegradable. Since the ready biodegradability of the test substance was proven (please refer to IUCLID section 5.2.1), an experimental investigation of its hydrolytic properties was not considered necessary.
Biodegradation
Biodegradation in water: screening test
The ready biodegradability of the test substance was investigated according to the OECD 301F (1992). The test substance undergoes 83 % biodegradation after 28 days. The test substance is regarded as readily biodegradable according to OECD guideline.
Transport and distribution
Adsorption/Desorption
In accordance with column 2 of REACH Annex VIII, the adsorption/desorption study (required in section 9.3.1) does not need to be conducted if the substance and its relevant degradation products decompose rapidly. As the substance is readily biodegradable no testing is necessary. In addition according to Annex IX, Section 9.3.3, column 2 of REACH Regulation (EC) No 1907/2006 a study on adsorption/desorption need not be conducted, if based on the physicochemical properties the substance can be expected to have a low potential for adsorption.The substance can be expected to have a low potential for adsorption (following REACh guidance Document R7.1.15.4): A log kow of 1.6 at 35 °C was determined which indicates low potential for adsorption (log Pow < 3).
Henry´s Law constant
The Henry's law constant was calculated to be 0.611 Pa m3/mol. The Henrys law constant is calculated according to ECHA guidance R.16: Environmental exposure assessment (ECHA 2016) using experimental data for water solubility and vapour pressure.
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.
