PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to the ECHA guidance on PBT/vPvB assessment (version 3.0, 2017), ZN-100 is not a PBT or vPvB substance.
Persistence Assessment
The OECD 301F tests conducted determined that ZN-100 is readily biodegradable. Therefore the substance is regarded as not being persistent (P) or very persistent (vP).
Bioaccumulation Assessment
The substance’s log Pow is < 1. Based on this, ZN-100 does not fulfill the bioaccumulative (B) and very bioaccumulative (vB) criteria.
Toxicity Assessment
The substance does not fulfil the toxicity (T) criterion as it is not classified as H350, H340, H372, H373, H350i, H360 and/or H361, none of the acute aquatic ecotoxicity LC50 and EC50 endpoints (for fish, daphnia and algae) are < 0.01 mg/L, the log Pow of < 1 is less than the trigger value of > 4.5, the substance is readily biodegradable and there is no other evidence that suggests chronic toxicity (as identified by the substance meeting the criteria for classification: STOT RE 1, or STOT RE 2 according to the CLP Regulation). Based on the above, the T criterion is not fulfilled.
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.
