- 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.

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
