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

Additional information

The low water solubility, rapid hydrolysis and use patterns of tris 2 -propylheptyl phosphite indicate that exposure to terrestrial organisms is unlikely to occur to any significant extent. Further, tris 2 -propylheptyl phosphite has been shown to be of a low order of toxicity for aquatic and mammalian endpoints.

Additionally, tris 2 -propylheptyl phosphite has a limited exposure profile.  It is used as a stabiliser in polymer formulations. As such, its use is limited to industrial locations where the use is in largely closed systems.  There is minimal release to the environment during these processes.  Once compounded into a polymer it stays in the matrix.  As such, any subsequent use of the formulated polymer would be considered an article with low release potential.
