Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No photolysis or chemical transformation detected for t-butylphenyl diphenyl phosphate.

Key value for chemical safety assessment

Additional information

Information 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 a study performed according to methodology comparable to OECD Guideline draft (Phototransformation of Chemicals in Water - Direct and Indirect Photolysis) no photolysis or chemical transformation of the reaction mass of t-butylphenyldiphenyl phosphate and bis-t-butylphenylphenyl phosphate and triphenyl phosphate was detected at a concentration of 1 ppm during the 14 -day test period.
