The calculated vapour pressure of Sodium
lactate is based on an estimated melting point and boiling point.
However, crystalline Sodium lactate has strong hygroscopic properties
and is extremely difficult to isolate. Therefore, the substance is only
manufactured and marketed as a concentrated aqueous solution. It can be
concluded that the experimental determination of the vapour pressure of
an aqueous solution of Sodium lactate is not representative for the
"pure" substance. Therefore, a QSAR estimation using MPBPVP v1.43 of
EpiSuite v4.1 is considered to be more practical in this case. The
estimated vapour pressure for "pure" Sodium lactate is 5.8E-8 Pa. The
substance is considered to be in the applicability domain of the model
and despite poor model accuracy, due to the usage of an estimated
melting point and boiling point for vapour pressure prediction MPBPVP
methodology is considered adequate for a regulatory conclusion.
The estimated vapour pressure for
Sodium lactate is 5.8E-8 Pa.
