PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence:
Reaction mass of CXN1-55 was found readily biodegradable. Substance therefore "not (v)P)".
Bioaccumulation:
Reaction mass of CXN1-55 has a log Kow =< 4.5. Substance therefore "not (v)B".
Toxicity:
Based on the results of a prenatal developmental study (OECD 414) together with the results of a ninety days repeated dose toxicity study, Reaction mass of CXN1-55 is classified as reproductive toxicant category 2 according to Regulation (EC) No. 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures. This implies that Reaction mass of CXN1-55 fulfils the toxicity criterion (T).
Substances are considered as PBT or vPvB substances when they fulfil the criteria for all three inherent properties P, B and T or both of the inherent properties vP and vB, respectively. As the test substance is found not to fulfill the criteria for the properties P and B, Reaction mass of CXN1-55 is not considered PBT or 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.
