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.
