Reference
Endpoint:
Henry's law constant
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
Key result
H:
0 atm m³/mol
Conclusions:
Lactic acid is unlikely to volatilize from water according to the Henry's Law Constant of 1.13*10^-7 atm m^3 mol^-1.
Executive summary:

Henry's law constant of lactic acid was estimated with EPISuite, as the quotient of its vapour pressure and its aqueous solubility. Since lactic acid is miscible with water, this is in fact an overestimation of its propensity to evaporate from water.

 

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.

Description of key information

The target substance L-lactide hydrolyses rapidly into lactic acid in aquatic environments and thus read-across to the source substance lactic acid is applicable and justified.

For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.

 

Lactic acid is unlikely to volatilize from water according to the Henry's Law Constant of 1.13*10-7 atm m³ mol-1.
