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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Not relevant due to low vapour pressure
Key value for chemical safety assessment
Additional information
No experimental data evaluating the potential for photodegradation of 2,3-dihydroxypropyl laurate (CAS No. 142-18-7) in air are available. Therefore, a QSAR calculation using the AOPWIN v1.92 program has been performed instead, resulting in an estimated half-life of 13.1 hours (reaction with OH-radicals, 24h-day)(López Parrón, 2011).This value indicates that the substance is susceptible to undergo rapid indirect photodegradation in air. Nevertheless, this is not expected to be a relevant environmental fate process, since the substance is not likely to be present in the atmosphere in relevant amounts based on its estimated vapour pressure (5.45 x 10E-07 Pa at 20 °C).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
