Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Using a QSAR calculation, the adsorption coefficient of the test material was estimated to be log10 Koc 0.472. Based on the low Koc the substance is less likely to adsorb to organic matter.

Key value for chemical safety assessment

Koc at 20 °C:
0.472

Additional information

No determination of the adsorption coefficient was possible by the HPLC estimation method, Method C19 of Commission Directive 200l/39/EC, as the method is not valid for organic acids. Therefore in place of experimental data, an estimate of the adsorption coefficient was obtained by calculation using Quantitative Structure Activity Relationships (QSAR's), the details of which are provided in the technical guidance documents in support of Commission Directive 93/67/EEC on risk assessment for new substances. Using a QSAR calculation, the adsorption coefficient of the test material was estimated to be log10 Koc 0.472.

Based on the low Koc the substance is less likely to adsorb to organic matter.
