Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- PBT status:
- the substance is not PBT / vPvB
- Justification:
8.1. Assessment of PBT/vPvB Properties - Comparison with the Criteria of Annex XIII
8.1.1. Persistence Assessment
A substance is not considered to be persistent if it can be demonstrated that it has potential to degrade (via photolysis, hydrolysis and/or biodegradation)
Based on the available measured data, the substance is biodegradable. Therefore, based on initial persistence screening the substance is not expected to meet the Persistent (P) or very Persistent (vP) criteria.
8.1.2. Bioaccumulation Assessment
As a screening criterion it has been established that if the log Kow of the substance is lower than 4.5 it indicates that the substance will not fulfil the bioaccumulative (B) or very bioaccumulative (vB) criteria.
Available experimental aquatic BCF or biomagnifications data can be compared directly against the B and vB criteria
As a screening criterion it has been established that if the log Kow of the substance is equal to or higher than 4.5, it indicates that the substance has a high bioaccumulation potential and therefore fulfils the B criterion.
Available experimental aquatic BCF or biomagnification data can be compared directly against the B and vB criteria.
n-hexane is there for not considered B or vB.
8.1.3. Toxicity Assessment
No representative structures were identified as PB or vPvB, therefore a toxicity assessment is not needed.
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.
