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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- PBT status:
- the substance is not PBT / vPvB
- Justification:
On the basis of the currently available information, the substance is expected to be not-PBT.
PERSISTENCE
The substance is expected to be not readily biodegradable. In addition, abiotic degradation by hydrolysis is considered as negligible, since the substance can be considered to be hydrolytically stable.
Based on the available information, the substance can be considered as potentially P or vP.
BIOACCUMULATION
Many substances with a molecular mass greater than 700 are not readily taken up by fish, because of possible steric hindrance at passage of gill membranes or cell membranes of respiratory organs. Acid Blue 134 has a molecular weight higher than 800 g/mol and is characterised by a negative log Kow.
Thus, B-criterion is not met.
TOXICITY
Aquatic long-term toxicity data is not available, therefore the aquatic toxicity assessment and classification are based mainly on the short-term toxicity data. Short-term toxicity studies show that the substance should be considered as harmful to aquatic life with long lasting effects for aquatic life, according to the criteria of CLP Regulation (EC) No 1272/2008.
The substance is not classified as carcinogenic, germ cell mutagenic, or toxic for reproduction and it does not meet the criteria of CLP Regulation (EC) No 1272/2008 to be classified for specific target organ toxicity after repeated exposure evidence of chronic toxicity.
A definitive conclusion about the T-criterion cannot be reached.
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.
