Description of key information
Partition coefficient data are available for the registration substance and for three read-across chemicals. The read-across chemicals are included in the Glycol Esters Category submitted by the American Chemistry Council for the U.S. Environmental Protection Agency as a contribution to the U.S. EPA High Production Volume Chemical Program. All members of this category have similar molecular structure and functional groups. The functional groups in common are aliphatic ester groups and glycol ether groups. The glycol ether groups, joined together in one to four units, are end-capped with aliphatic acids via ester groups. The read-across chemicals as well as the chemical to be registered all have strongly positive partition coefficients.
The KOWWIN module (v1.68) of the U.S. EPA EpiSuite program (Copyright 2000 -2012) was used to calculate a partition coefficient for the subject chemical. The value obtained bu this method was 5.3278 (LogKow) and is consistent with the values for the other similar read-across chemical.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.43

Additional information
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.
