Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

No experimental data on the hydrolysis of sodium lactate are available. In aqueous environments, sodium lactate fully dissociates into Na+ ions and lactate ions. Therefore, transport and distribution behaviour of sodium lactate in the environment can be understood in terms of the transport and distribution behaviour of sodium chloride and lactic acid.

In accordance with Regulation (EC) No 1907/2006 (REACH) annex VIII, column 2, a hydrolysis study is not required if the substance is readily biodegradable.

Lactic acid is readily biodegradable and the sodium compound is as such not hydrolysable.
