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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- Reactive Scarlet F07-0522
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Reference substance:
- Reactive Scarlet F07-0522
- Reference substance:
- Reactive Scarlet F07-0522
- Reference substance:
- Reactive Scarlet F07-0522
- Reference substance:
- Reactive Scarlet F07-0522
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The test substance is not readily or inherently biodegradable, however, experimental studies on hydrolytic effects demonstrated that the substance does undergo hydrolysis at environmentally relevant pH, with a half life of 2.7 days at pH 7, and shorter than one day at pH 9, at 25°C. As such, degradation is anticipated via this route.
Due to its good water solubility and low solubility in n-octanol (log Kow < -4.5) the test substance is considered to be not bioaccumulative.
While chronic aquatic toxicity data are not available, the substance is not considered toxic based on consideration of the acute aquatic toxicity data (including results of studies in fish, daphnia and algae), which do not fulfil the screening criteria for toxicity based on the EC50 values of these studies. No repeated dose toxicity to humans is known. In addition, due to the absence of effects seen in the reproductive toxicity screen study (OECD 421) and the negative assessment of mutagenicity the substance is neither classified for CMR properties nor for repeated dose toxicity/specific target organ toxicity upon repeat exposure. Thus, the substance also does not fulfil the T-criterion.
Consequential, the substance is considered neither PBT nor vPvB.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
