Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The logPow of Resin 835A is high if the Resin is in the undissociated state. The dissociation constant was calculated to 5.1 so that at environmentally relevant pH in the neutral range the sparingly dissoluted substance will be in the dissociated state, which would result in a much lower logPow. Although formally a candidate for a bioaccumulative substance it is under realistic conditions probably not bioaccumulative.

This matches with the determined relatively low adsorption coefficient of logKoc of >0.9 to <2 at pH 6.5 (an environmentally relevant pH). The adsorption coefficient points to a ca. 10 to 100 times higher concentration in sediment and soil than in water, so that the concentrations in soil and sediment are still very low and are also considered to be insignificant.

Therefore no further studies are proposed.
