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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 418-220-4 | CAS number: - RED JB 747
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
RED JB 747 is hydrolytically stable at pH range from 4 to 9, with an estimated t1/2 > 1 year at 25 °C and it is not readily and inherently biodegradable by microorganisms. Despite its persistence, RED JB 747 shows a very high affinity to the water phase (logKow = -2.9) which excludes a bioaccumulation potential in organisms.
The substance is neither classified for CMR properties nor for specific target organ toxicity, repeat exposure.
Despite no long term toxicity data are available for aquatic organisms, it could be possible to conclude that the substance will not be chronically toxic for aquatic organisms and, with reasonable probability, its LC/E50 or NOEC will not be below the threshold value of 0.01 mg/L required for the toxicity “T” classification.
For these reasons, according to REACH regulation, Annex XIII (section 1), the substance does not meet the criteria for PBT classification, since only the criteria for persistence has been satisfied.
- Likely routes of exposure:
Due to its high affinity to the hydrophilic phase and because bioaccumulation is not significant, exposure from the consumption of contaminated water seems to be the most relevant route.
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).
