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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
PETMP is considered to have a low potential for bioaccumulation according to the log Pow reported to be ca. 2.8 at pH 7 and 30 °C (see chapter 4.7).
The BCF for the aquatic environment was calculated to be 23.7 using the software BCFBAF v3.00 (2008) implemented in Epi Suite developed by US EPA.The substance is not stable in the aquatic environment. However, it is not experimentally confirmed which mechanisms is the primary cause for the degradation, hydrolysis or oxidation. The hydrolysis test showed the fast elimination of the test substance, probably due to oxidation.
Thus, testing on bioconcentration of PETMP in aquatic organisms is not considered to provide further relevant information for the bioaccumulation assessment as the calculated BCF is far below 2000 which is the criterion for a substance to be classified as 'B'. Additionally, the log Pow of PETMP is lower than 4.5 which is a screening criterion for bioaccumulating substances.
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.
