Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Potassium-S-lactate fully dissociates into K+ ions and lactic acid in aqueous environments. Therefore, the transport and distribution behaviour of potassium-S-lactate in the environment can be understood in terms of the transport and distribution behaviour of potassium chloride and lactic acid. Read-across from these two substances is considered feasible.
Potassium-S-lactate does not contain any functional groups that are susceptible to hydrolysis.
Based on unequivocally positive QSAR predictions (BIOWIN v4.10) and a supporting study investigating the biochemical oxygen demand (BOD) lactic acid is readily biodegradable, and therefore also potassium-S-lactate is considered to be readily biodegradable. Potassium chloride is inorganic and has a high water solubility. Potassium and chloride ions are essential constituents of the body of all organisms and the concentrations of both ions are maintained by active regulation. Lactic acid is highly soluble in water, has a low log Kow (-0.72) and is readily biodegradable. Both potassium chloride and lactic acid will not bioaccumulate, therefore neither potassium-S-lactate is expected to bioaccumulate or bioconcentrate.
Adsorption of potassium chloride is not predicted to occur to an appreciable extent. The substance is inorganic and has a high water solubility. Due to its physicochemical properties, lactic acid will be present, remain, or distribute to, aqueous compartments, and will be rapidly degraded or metabolized there.
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.
