Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
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
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
flakes
Colour:
White
Substance type:
organic
Conclusions:
L-lactide was found to be solid at room temperature.
Executive summary:

In summary, L-lactide was found to be solid at room temperature determined by visual observations. L-lactide is a suitable read across partner as Dilactide is a mixture of D- and L-lactide isomers.

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.
