PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
In a study according to OECD 301 E a biodegradation of 8 % was observed after 28 d. The n-octanol/water partition coefficient (logPow) of Cyclen was determined to be <-1.5. NOEC and EC10 were determined to be > 0.01 mg/L for marine/freshwater organisms. The substance is not classified as CMR and no other evidence of chronic toxicity or specific target organ toxicity is present. Thus, Cyclen is neither PBT nor 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.
