Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Log Kow (Log Pow):
0.45
at the temperature of:
22 °C

Additional information

GMT 80% has been tested to determine the octanol-water partition coefficient by using the HPLC method according to OECD 117 (EU A.8.) The peak of glyceryl monomercaptoacetate corresponds to a logPow of 0.45 at 22 °C. This logPow was selected as key value for chemical safety assessment because this value considers the varying amounts of glycerol in the reaction mass of glycerol and thioglycolic acid in a sufficient and realistic manner.
