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 reaction mass of tert-butylphenyl diphenyl phosphate and di-tert-butylphenyl phenyl phoshate is a lipophylic substance with a log Kow of 5.61 (= log Kow of the main constituent). The substance has a slight potential for bioaccumulation as indicated by the selected key BCF value of 1850. Furthermore, the reaction mass of tert-butylphenyl diphenyl phosphate and di-tert-butylphenyl phenyl phoshate is readily biodegradable and in a river-die-away test with a read-across substance composed of similar constituents, the half-life was found to be 1 day at 24 ºC. Therefore as the substance is clearly not persistent, it is highly unlikely that reaction mass of tert-butylphenyl diphenyl phosphate and di-tert-butylphenyl phenyl phoshate will bioaccumulate to any significant extent.

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).
