Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
2 assays were performed :
Assay No. 1:
No freezing point was observed down to -50°C (223.15 K). The
test item was a fluid and clear liquid at the start of the
test, it was whitish and viscous when the test was stopped
after 24 minutes and 20 seconds.
Assay No. 2:
No freezing point was observed down to -50°C (223.15 K). The
test item was a fluid and clear liquid at the start of the
test, it was whitish and viscous when the test was stopped
after 23 minutes and 20 seconds.
The graphs of the resutls are in attached file.
Description of key information
The freezing point of isooctyl mercaptoacetate was measured to be below -50°C (Mourgues 2003).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -50 °C
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.
