Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density:
1.31 g/cm³
Temp.:
20 °C
Conclusions:
In conclusion, it can be stated that the relative density of D-lactide at 20 °C is 1.31.
Executive summary:

The density has been determined in accordance with OECD 109 resp. EU A.3. By applying the pycnometer method, a density of 1.31 g/cm³ at 20 °C was measured. The relative density was 1.31.

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

A gas comparison pycnometer was used for the determination of the density and relative density of D-lactide and L-lactide. The outcome was similar for the two lactides and is fully valid for dilactide as dilactide is a mixture of D- and L-lactide isomers. The density of the test substances were 1.31-1.33 g/cm³. The relative density were determined to be 1.31-1.33.

Key value for chemical safety assessment

Relative density at 20C:
1.31
