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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
- Measurement of the partition coefficient is technically not feasible because the substance is hydrolytically instable. Instead a QSAR calculation was performed using Estimation Programs Interface Suite™ for Microsoft® Windows v4.11. The prediction revealed a logKow of 0.81 for glycolide.
- The partition coefficient of glycolic acid, the break down product of hydrolytically instable glycolide, was determined to be < 0.3 according to the available information of Collander, R. (1951)
Key value for chemical safety assessment
Additional information
The substance glycolide is hydrolytically instable and decomposes to glycolic acid, thus experimental determination of the partition coefficient is not possible. In order to predict the logKow of glycolide a QSAR estimation was performed. Furthermore, there are data from published studies.
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.
