Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
P-PP photodegrades in air (the half-life was calculated to be 0.391 days) but will not hydrolyse, nor does it biodegrade. Although the Log Kow is above 3 (3.81) a bioaccumulation study in carp indicates that P-PP has a limited capacity to bioaccumulate (less than 60 fold over the duration of the study). The Log Koc of 2.43 (Koc 273) determined by HPLC indicates that P-PP has a limited capacity to adsorb on to soil and sediment. P-PP is imported into the EU and used at a limited number of sites where it is added to and reacts with resins. After the reaction, P-PP no longer exists. Water is not used in the process nor is it used for cleaning. Direct emissions to water are therefore very unlikely and good practice industrial hygiene will minimise indirect exposure via the air (where some photodegradation is predicted) to water or soil.
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.
