Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The environmental fate of ammonium-S-lactate is assessed via read-across from its compounds lactic acid and ammonia. Based on these information, ammonium-S-lactate is readily biodegradable. The adsorption coefficient does not need to be analysed, as the log Kow for ammonium-S-lactate is expected to be low: -3.84 (modelled with EPISuite v. 4.1).
However, the adsorption/desorption coefficient of lactic acid was estimated to be approximately 1 L/kg using the QSAR model KOCWIN v2.00. Hence, distribution is equal between water and soil for lactic acid. As ammonia is poorly mobile in soil, it is the main compartment for ammonia to remain in. Moreover, lactic acid and ammonia are rapidly transformed and degraded in the environment.
Additional information
This information is used in a read-across approach in the assessment of the target substance. For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.
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.
