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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 1,4-Dihydroxyanthraquinone
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Reference substance:
- 1,4-Dihydroxyanthraquinone
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Although the partition coefficient, low biodegradation rates (from one study on the registered substance) and aquatic toxicity would suggest properties are close to those leading to PBT, it is considered that PBT does not apply based on data present.
As well as the single screening study performed on the substance itself, there are published data on this class of substance suggestign biodegradation occurs.
The fact that hydroxyanthraquinones are formed in plants would suggest ultimate biodegradation and no accumulation.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
