Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
TCP has a low toxicity potential for terrestrial micro-organisms
Key value for chemical safety assessment
Additional information
Walton et al (1989) investigated the effect of a nominal concentration of 1000 µg TCP/kg soil upon the microbial activity in two different soils (silty and sandy loam) by measuring soil respiration as an indicator for microbial activity. TCP exhibited 7.74 and 17% reduction compared to the control, which suggests a 4-day EC10 and 4-day EC25 of < 1 g/kg soil dw for Captina silt loam and McLaurin sandy loam respectively. In both soils the 6-day EC0 was < 1 g/kg soil dw.
In conclusion these results indicate a low toxicity potential of TCP for terrestrial micro-organisms.
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.
