Description of key information

Miscible in water and polar solvents.  Partition coefficient less than 1 (Log Kow - 1.6)

Key value for chemical safety assessment

Log Kow (Log Pow):
-1.3
at the temperature of:
24 °C

Additional information

Initial QSAR estimate and literature references of Log Kow -1.6 was confirmed to be Log Kow -1.3 by a subsequent Shake-Flask test performed at the request of ECHA. Malic acid is miscible in water at all pH levels and is naturally occurring as an intermediate in aerobic metabolic processes; the partition coefficient is academic and not relevant for environmental risk assessment.
