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

A Final Decision letter (CCH-D-2114412576-50-01-F) was received for this substance on 09 July 2018 which requested further information on the PBT properties of the Block 10 Aldehyde consituents in this substance. As a first step Abietal was chosen to represent the Aldehyde Block 10 consituents and a ready biodegradation study was comissioned and depending on the outcome of that study the requirement for further testing for Persistence, Bioaccumulation and Toxicity would not be required.

The results show that Abietal meets the criteria in the OECD 301B to be labelled readily biodegradable e.g. at least 60% biodegradation in 28 days. Meeting the 10-day window was not a requirement according to both the ECHA Final Decision Letter and OECD guidance documents.

The test item is non-persistent, and satisfies the criteria to be labelled readily biodegradable based on the results obtained in the second experiment.

Therefore, no further work on the persistence of DTO or its consituents is required.
