PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Likely routes of exposure:
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
The substance is readily biodegradable based on screening criteria.This was shown in a study according to OECD 301 F (62% biodegradation after 28 d, 10 day-window fulfilled). Thus, the substance does not meet the screening criterion for persistency and is not considered to be not persistent (P) or very persistent (vP) in the environment.
Bioaccumulation
Due to the low log Kow value of <-2.7 bioaccumulation is not expected. Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB) in accordance with ECHA Guidance R.11 (ECHA, 2017).
Toxicity
Acute aquatic toxicity studies are available for fish, aquatic invertebrates and algae. No effects were observed for all three trophic levels up to a test item concentration of 100 mg/L. Moreover, the substance is not classified as carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B) or toxic for reproduction (category 1A, 1B or 2) according to the consolidated version of Regulation (EC) No. 1272/2008 and all further amendments (ATPs). Thus, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not met and the test substance is not considered to meet the T criterion.
In conclusion, the substance is not PBT/vPvB.
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.
