Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Studies concerning toxicity to soil microorganisms have been waived based on the neglible expected exposure (high volatility of CTC and the low adsorption of CTC to the soil)

Key value for chemical safety assessment

Short-term EC50 for soil microorganisms:
1 mg/kg soil dw

Additional information

Based on the results of Walton et al (1989) some reversible effects are reported at a high concentration of 1 mg/g dw. As volatility of CTC is high, it is considered that CTC is not significantly present in soils; hence no further data generation is planned.
