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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 916-604-0 | CAS number: -
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence
Taking into account the lack of biodegradation in a ready biodegradation test (OECD 301B), Basic Brown 17 is considered as potentially persistent or very persistent on the basis of screening criteria.
Bioaccumulation
The octanol water partition coefficient log Kow is -0.15 (EU A.8). This low log Kow indicates that the substance has hydrophilic properties and is not considered as bioaccumulable or very bioaccumulable.
Toxicity
Available data : EC50/algae/72 hours = 0.085 mg/L (OECD 201), EC50/daphnia magna/48 hours = 21.0 mg/L (OECD 202).
Criteria : Acute E(L)C50 from standard acute toxicity tests <0.1 mg/L.
The substance is not classified as carcinogenic (cat. 1A or 1B), nor germ cell mutagenic (Cat. 1A or 1B), nor toxic for the reproduction ((cat. 1A, 1B or 2). It is not classified as "Specific Target Organ Toxicity Repeated Exposure category 1 or category 2 ".
Screening assignment : T screening criteria met based on acute aquatic toxicity tests.
Basic Brown 17 is potentially Vp/P and Toxic but not B/vB. It is therefore not PBT or vP/vB.
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.
