Description of key information

Additional information

No information on the potential of the substance for hydrolysis is available as the substance is considered readily biodegradable.

Some information on phototransformation on the read-across substance Santicizer 154 is available. As the main component is the same for S-154 and the substance of concern (reaction mass of tert-butylphenyl diphenyl phosphate and di-tert-butylphenyl phenyl phosphate) the information on S-154 is relevant for this substance as well. In this study - performed according to the methodology comparable to the OECD Guideline draft (Phototransformation of Chemicals in Water - Direct and Indirect Photolysis) no photolysis of chemical transformation of the substance was detected at a concentration o f 1 ppm during during the 14 -day test period. Consequently it can be concluded that phototransformation is not a relevant degradation pathway.
