Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with Regulation (EC) No. 1907/2006, Column 2, Section 7.7, of REACH Annex VII, the study does not need to be conducted if the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours), or the substance is readily oxidisable in water. The substance, like all cyclic acid anhydrides, is anticipated to hydrolyse rapidly in water (t1/2< 12 hr). Therefore, the criterion for adaptation is met.

However, for the purpose of exposure assessment, the models require a value for solubility, therefore a conservative value of 10g/L is used for the CSR.
