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.
