Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The test substance Dantocol DHE meets the P criterion but does not meet the B or T criteria based on the following evidence:
Persistence: The evidence indicates the test substance is Persistent. A maximum of 17% biodegradation was observed after 28 days in ready biodegradation studies. An inherent biodegradation study demonstrated no potential for biodegradation. The hydrolysis half-life was calculated at >1 year.
Bioaccumulation: ECHA guidance states that where the Log Kow of a test substance is ≤3, the requirement for bioaccumulation testing can be waived as the test substance has a low potential to bioaccumlate. The Log Kow of the test substance was measured as -1.32 in a validated, acceptable GLP study and therefore the potential for bioaccumulation in aquatic organisms is considered low. The test substance does not meet the B criterion.
Toxicity: The lowest toxicity value for the test substance is 100 mg/L, which is several orders of magnitude greater than the T criterion of <0.01 mg/L. The test substance is not classified as carcinogenic (category 1A or 1B), germ mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2). The test substance is not classified for chronic toxicity, as identified by the classifications STOT (repeated exposure), category 1 or category 2 according to Regulation (EC) No 1272/2008.
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.
