Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- cloquintocet-mexyl technical
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- cloquintocet-mexyl technical
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Conclusion on persistence:
The half-lives of cloquintocet-mexyl in soil and water/sediment systems are well below the threshold criteria in accordance with Annex XIII, thus indicating a non-persistent substance (not P or vP).
Conclusion on bioaccumulation:
Based on measured data from a fish bioconcentration study, the whole fish BCF was 621, significantly lower than the threshold of concern of 2000. Cloquintocet-mexyl is, therefore, not bioaccumulative (not B or vB).
Conclusion on toxicity:
The NOEC, from recognised long-term toxicity studies with aquatic organisms, ranges from 0.09 mg/L (algae) to 0.437 mg/L (invertebrates). In all cases, the NOEC values are >0.01 mg/L. Therefore, cloquintocet-mexyl does not fulfil the toxicity criterion based on hazards to the environment (not T). The substance is not classified as carcinogenic, mutagenic or toxic to reproduction. Based on the results of repeated dose toxicity studies, the substance is classified for specific target organ toxicity following repeated exposure (STOT RE Cat. 2), and hence is considered as toxic (T).
- Likely routes of exposure:
Not applicable as the substance is not PBT and not vPvB.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
