Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No experimental data evaluating the potential of Glycerides, mixed C8-10 and succinyl (CAS No. 91744-56-8) to undergo photodegradation in air are available. Since the substance is an UVCB, QSAR calculations using the AOPWIN v1.92 program have been performed on the most representative components, resulting in estimated half-lives ranging from 4.8 to 12.7 hours (reaction with OH-radicals, based on a 24-h day)(López Parrón, 2012). These values indicate that Glycerides, mixed C8-10 and succinyl is susceptible to undergo rapid indirect phototransformation if released into the 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 vapour pressure (< 5 Pa at 20°C).
