Adequacy of study:
key study
Study period:
August 2015
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
according to guideline
other: ECHA guidance on information requirements and chemical safety assessment, chapter R.6: QSARs and grouping of chemicals
GLP compliance:
Type of method:
other: QSAR, modified grain method
Specific details on test material used for the study:
SMILES: CC1C(=O)OC(C(=O)O1)C (canonical); C[C@@H]1C(=O)O[C@@H](C(=O)O1)C (isomeric)
Key result
25 °C
Vapour pressure:
0.28 Pa
Remarks on result:
other: Estimation of vapour pressure is reliable since experimental values for melting point and boiling point are available.
The vapour pressure of DD-lactide is 0.28 Pa at 25 °C, obtained by QSAR calculation.
Executive summary:

The vapour pressure of DD-lactide was estimated by QSAR calculation (MPBPWin v1.43, EpiSuite). Experimental values for melting point and boiling point were taken into account. The resulting vapour pressure of DD-lactide is 0.28 Pa at 25 °C.

Description of key information

The vapour pressure of DD-lactide is 0.28 Pa at 25 °C (QSAR calculation).

Key value for chemical safety assessment

Vapour pressure:
0.28 Pa
at the temperature of:
