Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of composition:
legal entity composition of the substance
State / form:
solid: particulate/powder
>= 87.5 - <= 100 % (w/w)
Reference substance:
Reference substance:
This impurity is considered relevant for the classification and labelling of the substance
PBT status:
the substance is not PBT / vPvB

The PBT Assessment for the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).


Persistency assessment

Two experimental studies are available investigating the biodegradability of the test substance. The studies were performed according to OECD 301D (GLP). After 28 d the substance was degraded to 79 - 92% meeting the 14-day window. Based on these results the substance is not considered to be P/vP based on the screening criteria.



The substance has an experimental BCF of < 0.5-15 L/kg (OECD 305C) which is clearly below the trigger value of 2000 L/kg. Thus, the substance is not considered to be B/vB based on the criteria in REACh Annex XIII.


Aquatic studies are available for three trophic levels. All acute effect concentrations were clearly > 0.1 mg/L (lowest LC50 (96 h): 15.6 mg/L). Moreover, the substance is not classified as carcinogenic, mutagenic or toxic to reproduction (CMR). Since the P/vP and B/vB criteria are not met a further assessment is not necessary in accordance with ECHA Guidance R.11. However, since the chronic effect concentration from the algae study is > 0.01 (NOErC (72 h): 4.6 mg/L) the substance presumably does not meet the T-criterion.
