Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.
- Reason / purpose for cross-reference:
- read-across source
- Water solubility:
- 1 086 g/L
- Conc. based on:
- other: The sodium content of the solution was determined by weighing the sulfate precipitate after decomposition with sulfuric acid.
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not reported in the literature.
- Conclusions:
- The maximum solubility of potassium lactate in water at 25 °C determined by gravimetric analysis is 1126 g/L (78 % w/w).
- Executive summary:
A concentrated solution of potassium lacTate was obtained by slow addition of a saturated solution of potassium hydroxide to the lactic acid. The potassium content of the solution was determined by gravimetric analysis (weighing of precipitate) after decomposition with sulfuric acid. The maximum solubility of potassium lactate in water at 25 °C is 1126 g/L (78 % w/w).
This information is used in a read-across approach in the assessment of the target substance. For justification of read-across please refer to the read-across report attached to IUCLID section 13.
Reference
Description of key information
A concentrated solution of Sodium lactate was obtained by slow addition of a saturated solution of sodium hydroxide to the lactic acid. The sodium content of the solution was determined by gravimetric analysis (weighing of precipitate) after decomposition with sulfuric acid. The maximum solubility of Sodium lactate in water at 25 °C is 1086 g/L (77.15 % w/w).
Based on this result, it is assumed that the water solubility of the target substance Sodium (S)-lactate is in the same range and therefore indicated with 1086 g/L.
Key value for chemical safety assessment
- Water solubility:
- 1 086 g/L
- at the temperature of:
- 25 °C
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.
