Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Partition coefficient of hydroxy(2-methylprop-2-enoato-O)zinc has a log Pow = 0.17 (arithmetical mean value of 3 QSARS results)
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.17
Additional information
It is thus concluded that the test item has a log POW = 0.17 for undissociated form and a log POW= 0.89 for the dissociated form (methacrylic acid)
Three QSARS estimated values for the partition coefficient of hydroxy(2-methylprop-2-enoato-O)zinc (neutral form) were reported and can be considered as consistent :
- The log Pow of hydroxy(2-methylprop-2-enoato-O)zinc was calculated to be -0.12 using Kowwin QSAR; -0.09 using Vcclab QSAR and 0.73 using Vega logP. A mean value can be calculated to give an approximate representative partition coefficient of the hydroxy(2-methylprop-2-enoato-O)zinc
The arithmetical mean value of these 3 results, log Pow = 0.17, will be retained as Key value for chemical assessment .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).
