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.

Additional information

We chose the study read-across from a standard test of TDCP as the key study. This study obeyed with the OECD TGD 106, which used a regression equation derived from a plot of log Kd versus logKoc (organic carbon concentration), which in order to derive a Koc from the plot. Taking account to the TCPP's structure similar with the TDCP, the regression equation was also applied to the TCPP, which indicated that the Koc of the TCPP was 174.

The relatively low volatility and moderate solubility and adsorption coefficient suggest that most TCPP found in the atmosphere will adsorb to particulate matter, which may then be washed out by rainfall. The TGD estimates this from vapour pressure, leading to a similar conclusion.
