Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification & Labelling & PBT assessment

PBT assessment

Currently viewing:

Administrative data

PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Comparison with the Criteria of Annex XIII. An assessment of the PBT/vPvB status of the test substance has been made using all available data.

Persistence Assessment.

Two CO2 evolution tests (OECD 301B; see Section 5.2.1) are available and used in a weight of evidence approach to show that the test substance is not readily biodegradable; the test substance is therefore identified as being potentially persistent based on this finding.

Bioaccumulation Assessment

No studies to assess bioaccumulation in aquatic species have been conducted. The low Log Kow value (<4.5) indicates that the test material is unlikely to be bioaccumulative in aquatic systems, and as such is considered to have a low potential for bioaccumulation.

Toxicity assessment

In a Daphnia Reproduction study (OECD 211), the chronic 21day NOEL was reported as 0.2 mg/L (Reproduction). This value is greater that the criteria to classify a substance as "toxic -T" in this assessment (NOEL <0.01 mg/L). Supporting evidence is provided in Acute (short-term) toxicity tests where chronic data are not available for certain trophic levels; the LC50/EC50 for fish and algae are higher than the PBT screening criterion of <0.1mg/L. The substance is also not considered to have CMR or STOT RE properties based on the results of the applicable tests. Therefore the test material is not T in accordance with the criteria in Annex XIII of the REACH regulation as amended.

The overall conclusions, based on the present available data, are that the (screening) criteria for PBT/vPvB, as outlined in Annex XIII of Directive 2006/121/EC, for B and vB are not met and the substance is not T in comparison with the available information and the criteria set. As the substance is not B, vB or T then further testing in the scope of the final PBT/vPvB assessment to assess P or vP is not considered to be required.
