Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Thioglycolic acid and its salts are highly soluble in water (> 1000 g/L at 20°C) (Sablowski and Fölsing, 2007) and thioglycolic acid has a partition coefficient octanol-water equal to -2.99 at 22°C and pH 7. Therefore thioglycolic acid is not expected to bioaccumulate according to technical guidance documents. Modeling is not necessarily appropriate for assessing bioaccumulation potential of inonizable substances. Therefore no estimated BCF is proposed.

In conclusion, based on their intrinsic chemical properties, thioglycolic acid and its salts when released in aquatic environment are not expected to represent a chronic hazard for aquatic or terrestrial species.
