Description of key information

The melting temperatures of LL-lactide and DD-lactide were determined using DSC. The outcome was the same for the two lactides and is fully valid for dilactide as dilactide is a mixture of D- and L-lactide isomers. The melting temperature of the test substance is 97 °C or 370 K. The experiments were performed under a flow of nitrogen and at atmospheric pressure.

Key value for chemical safety assessment
