Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Sodium lactate as such is a solid organic salt, but due to its hygroscopic properties, it is only available and marketed as an aqueous solution. Therefore, the melting and boiling point of “pure” Sodium lactate are calculated using QSAR and are 174.03 °C and 436.7 °C, respectively. The ionic compound has a water solubility of 1086 g/L at 25 °C. The corresponding partition coefficient octanol-water was determined in a study conducted according to OECD 107 with log Pow -1.52 at 20 °C, which is derived by read across to its enantiomer, Sodium (S)-lactate (chirality has no or only minor influence on this physical-chemical property).
As pure Sodium lactate is not available, the relative density of the substance can only be indicated for highly concentrated (60 - 77.15 % w/w) aqueous solutions. The values range from 1.3131 for a 60 % w/w solution to 1.4085 for a 77.15 % w/w solution. The QSAR estimate for vapour pressure indicates a negligible value of 5.8E-8 Pa for the pure substance. A calculation of the pKa value was not possible as no half-equivalence point could be determined with the titration method conducted according to OECD 112. The surface tension of the target substance is 71.8 mN/m at 20.0 °C as determined in a GLP study conducted according to OECD 115 and EU Method A.5 and in addition surface tension is a desired property of the substance. Finally, Sodium lactate has neither flammable, explosive nor oxidizing properties.
Additional information
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.
